Timentin Injection





Dosage Form: injection, solution
TIMENTIN®

(sterile ticarcillin disodium and clavulanate potassium)

FOR INTRAVENOUS ADMINISTRATION

PHARMACY BULK PACKAGE

NOT FOR DIRECT INFUSION

RECONSTITUTED STOCK SOLUTION MUST BE TRANSFERRED AND FURTHER DILUTED FOR IV INFUSION.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of TIMENTIN (ticarcillin disodium and clavulanate potassium) and other antibacterial drugs, TIMENTIN should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.



PACKAGE DESCRIPTION


TIMENTIN is available in a 31-gram Pharmacy Bulk Package. This sterile dosage form contains multiple-single doses for use in a pharmacy admixture program for the preparation of parenteral fluids.



PRODUCT DESCRIPTION


TIMENTIN is a sterile injectable antibacterial combination consisting of the semisynthetic antibiotic ticarcillin disodium and the β-lactamase inhibitor clavulanate potassium (the potassium salt of clavulanic acid) for intravenous administration. Ticarcillin is derived from the basic penicillin nucleus, 6-amino-penicillanic acid.


Chemically, ticarcillin disodium is N-(2-Carboxy-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]hept-6-yl)-3-thiophenemalonamic acid disodium salt and may be represented as:



Clavulanic acid is produced by the fermentation of Streptomyces clavuligerus. It is a β-lactam structurally related to the penicillins and possesses the ability to inactivate a wide variety of β-lactamases by blocking the active sites of these enzymes. Clavulanic acid is particularly active against the clinically important plasmid-mediated β-lactamases frequently responsible for transferred drug resistance to penicillins and cephalosporins.


Chemically, clavulanate potassium is potassium (Z)-(2R,5R)-3-(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo[3.2.0]heptane-2-carboxylate and may be represented structurally as:



TIMENTIN is supplied as a white to pale yellow powder for reconstitution. TIMENTIN is very soluble in water, its solubility being greater than 600 mg/mL. The reconstituted solution is clear, colorless or pale yellow, having a pH of 5.5 to 7.5.


For the 3.1-gram dosage of TIMENTIN, the theoretical sodium content is 4.51 mEq (103.6 mg) per gram of TIMENTIN. The theoretical potassium content is 0.15 mEq (6 mg) per gram of TIMENTIN.



Timentin Injection - Clinical Pharmacology


After an intravenous infusion (30 min.) of 3.1 grams of TIMENTIN, peak serum concentrations of both ticarcillin and clavulanic acid are attained immediately after completion of infusion. Ticarcillin serum levels are similar to those produced by the administration of equivalent amounts of ticarcillin alone with a mean peak serum level of 330 mcg/mL. The corresponding mean peak serum level for clavulanic acid was 8 mcg/mL. (See following table.)

The mean area under the serum concentration curve was 485 mcg•hr/mL for ticarcillin and 8.2 mcg•hr/mL for clavulanic acid.


The mean serum half-lives of ticarcillin and clavulanic acid in healthy volunteers are 1.1 hours and 1.1 hours, respectively.


In pediatric patients receiving approximately 50 mg/kg of TIMENTIN (30:1 ratio ticarcillin to clavulanate), mean ticarcillin serum half-lives were 4.4 hours in neonates (n = 18) and 1.0 hour in infants and children (n = 41). The corresponding clavulanate serum half-lives averaged 1.9 hours in neonates (n = 14) and 0.9 hour in infants and children (n = 40). Area under the serum concentration time curves averaged 339 mcg•hr/mL in infants and children (n = 41), whereas the corresponding mean clavulanate area under the serum concentration time curves was approximately 7 mcg•hr/mL in the same population (n = 40).


Approximately 60% to 70% of ticarcillin and approximately 35% to 45% of clavulanic acid are excreted unchanged in urine during the first 6 hours after administration of a single dose of TIMENTIN to normal volunteers with normal renal function. Two hours after an intravenous injection of 3.1 grams of TIMENTIN, concentrations of ticarcillin in urine generally exceed 1,500 mcg/mL. The corresponding concentrations of clavulanic acid in urine generally exceed 40 mcg/mL. By 4 to 6 hours after injection, the urine concentrations of ticarcillin and clavulanic acid usually decline to approximately 190 mcg/mL and 2 mcg/mL, respectively. Neither component of TIMENTIN is highly protein bound; ticarcillin has been found to be approximately 45% bound to human serum protein and clavulanic acid approximately 25% bound.


Somewhat higher and more prolonged serum levels of ticarcillin can be achieved with the concurrent administration of probenecid; however, probenecid does not enhance the serum levels of clavulanic acid.


Ticarcillin can be detected in tissues and interstitial fluid following parenteral administration.


Penetration of ticarcillin into bile and pleural fluid has been demonstrated. The results of experiments involving the administration of clavulanic acid to animals suggest that this compound, like ticarcillin, is well distributed in body tissues.


An inverse relationship exists between the serum half-life of ticarcillin and creatinine clearance. The dosage of TIMENTIN need only be adjusted in cases of severe renal impairment. (See DOSAGE AND ADMINISTRATION.)


Ticarcillin may be removed from patients undergoing dialysis; the actual amount removed depends on the duration and type of dialysis.



Microbiology


Ticarcillin is a semisynthetic antibiotic with a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria.


Ticarcillin is, however, susceptible to degradation by β-lactamases, and therefore, the spectrum of activity does not normally include organisms which produce these enzymes.


Clavulanic acid is a β-lactam, structurally related to the penicillins, which possesses the ability to inactivate a wide range of β-lactamase enzymes commonly found in microorganisms resistant to penicillins and cephalosporins. In particular, it has good activity against the clinically important plasmid-mediated β-lactamases frequently responsible for transferred drug resistance.


The formulation of ticarcillin with clavulanic acid in TIMENTIN protects ticarcillin from degradation by β-lactamase enzymes and effectively extends the antibiotic spectrum of ticarcillin to include many bacteria normally resistant to ticarcillin and other β-lactam antibiotics. Thus, TIMENTIN possesses the distinctive properties of a broad-spectrum antibiotic and a β-lactamase inhibitor. Ticarcillin/clavulanic acid has been shown to be active against most strains of the following microorganisms, both in vitro and in clinical infections as described in the INDICATIONS AND USAGE section.

In vitro synergism between TIMENTIN and gentamicin, tobramycin, or amikacin against multiresistant strains of Pseudomonas aeruginosa has been demonstrated.



Susceptibility Testing


Dilution Techniques

Quantitative methods are used to determine antimicrobial MICs. These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs should be determined using a standardized procedure. Standardized procedures are based on a dilution method1,3 (broth or agar) or equivalent with standardized inoculum concentrations and standardized concentrations of ticarcillin/clavulanate potassium powder.


The recommended dilution pattern utilizes a constant level of 2 mcg/mL clavulanic acid in all tubes with varying amounts of ticarcillin. MICs are expressed in terms of the ticarcillin concentration in the presence of clavulanic acid at a constant 2 mcg/mL. The MIC values should be interpreted according to the following criteria:


RECOMMENDED RANGES FOR TICARCILLIN/CLAVULANIC ACID SUSCEPTIBILITY TESTING*

* Expressed as concentration of ticarcillin in the presence of clavulanic acid at a constant 2 mcg/mL.


† Staphylococci that are susceptible to ticarcillin/clavulanic acid but resistant to methicillin/oxacillin must be considered as resistant.


A report of “Susceptible” indicates that the pathogen is likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable. A report of “Intermediate” indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone that prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of “Resistant” indicates that the pathogen is not likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable; other therapy should be selected.


Standardized susceptibility test procedures require the use of laboratory control microorganisms to control the technical aspects of the laboratory procedures. Standard ticarcillin/clavulanate potassium powder should provide the following MIC values3:

Diffusion Techniques

Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedure2,3 requires the use of standardized inoculum concentrations. This procedure uses paper disks impregnated with 85 mcg of ticarcillin/clavulanate potassium (75 mcg ticarcillin plus 10 mcg clavulanate potassium) to test the susceptibility of microorganisms to ticarcillin/clavulanic acid.


Reports from the laboratory providing results of the standard single-disk susceptibility test with an 85 mcg of ticarcillin/clavulanate potassium (75 mcg ticarcillin plus 10 mcg clavulanate potassium) disk should be interpreted according to the following criteria:

Interpretation should be as stated above for results using dilution techniques. Interpretation involves correlation of the diameter obtained in the disk test with the MIC for ticarcillin/clavulanic acid.


As with standardized dilution techniques, diffusion methods require the use of laboratory control microorganisms that are used to control the technical aspects of the laboratory procedures. For the diffusion technique, the 85 mcg of ticarcillin/clavulanate potassium (75 mcg ticarcillin plus 10 mcg clavulanate potassium) disk should provide the following zone diameters in these laboratory test quality control strains:

Anaerobic Techniques

For anaerobic bacteria, the susceptibility to ticarcillin/clavulanic acid can be determined by standardized test methods3,4. The MIC values obtained should be interpreted according to the following criteria:

Indications and Usage for Timentin Injection


TIMENTIN is indicated in the treatment of infections caused by susceptible strains of the designated microorganisms in the conditions listed below:


Septicemia (including bacteremia) caused by β-lactamase–producing strains of Klebsiella spp.*, E. coli*, S. aureus*, or P. aeruginosa* (or other Pseudomonas species*)


Lower Respiratory Infections caused by β-lactamase–producing strains of S. aureus, H. influenzae*, or Klebsiella spp.*


Bone and Joint Infections caused by β-lactamase–producing strains of S. aureus


Skin and Skin Structure Infections caused by β-lactamase–producing strains of S. aureus, Klebsiella spp.*, or E. coli*


Urinary Tract Infections (complicated and uncomplicated) caused by β-lactamase–producing strains of E. coli, Klebsiella spp., P. aeruginosa* (or other Pseudomonas spp.*), Citrobacter spp.*, Enterobacter cloacae*, S. marcescens*, or S. aureus*


Gynecologic Infections endometritis caused by β-lactamase–producing strains of P. melaninogenicus*, Enterobacter spp. (including E. cloacae*), E. coli, K. pneumoniae*, S. aureus, or S. epidermidis


Intra-abdominal Infections peritonitis caused by β-lactamase–producing strains of E. coli, K. pneumoniae, or B. fragilis* group


*Efficacy for this organism in this organ system was studied in fewer than 10 infections.


NOTE: For information on use in pediatric patients (≥3 months of age) see PRECAUTIONS—Pediatric Use and CLINICAL STUDIES sections. There are insufficient data to support the use of TIMENTIN in pediatric patients under 3 months of age or for the treatment of septicemia and/or infections in the pediatric population where the suspected or proven pathogen is H. influenzae type b.


While TIMENTIN is indicated only for the conditions listed above, infections caused by ticarcillin-susceptible organisms are also amenable to treatment with TIMENTIN due to its ticarcillin content. Therefore, mixed infections caused by ticarcillin-susceptible organisms and β-lactamase–producing organisms susceptible to ticarcillin/clavulanic acid should not require the addition of another antibiotic.


Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify organisms causing infection and to determine their susceptibility to ticarcillin/clavulanic acid. Because of its broad spectrum of bactericidal activity against gram-positive and gram-negative bacteria, TIMENTIN is particularly useful for the treatment of mixed infections and for presumptive therapy prior to the identification of the causative organisms. TIMENTIN has been shown to be effective as single drug therapy in the treatment of some serious infections where normally combination antibiotic therapy might be employed. Therapy with TIMENTIN may be initiated before results of such tests are known when there is reason to believe the infection may involve any of the β-lactamase–producing organisms listed above.


Based on the in vitro synergism between ticarcillin/clavulanic acid and aminoglycosides against certain strains of P. aeruginosa, combined therapy has been successful, especially in patients with impaired host defenses. Both drugs should be used in full therapeutic doses.


To reduce the development of drug-resistant bacteria and maintain the effectiveness of TIMENTIN and other antibacterial drugs, TIMENTIN should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.



Contraindications


TIMENTIN is contraindicated in patients with a history of hypersensitivity reactions to any of the penicillins.



Warnings


SERIOUS AND OCCASIONALLY FATAL HYPERSENSITIVITY (ANAPHYLACTIC) REACTIONS HAVE BEEN REPORTED IN PATIENTS ON PENICILLIN THERAPY. THESE REACTIONS ARE MORE LIKELY TO OCCUR IN INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY AND/OR A HISTORY OF SENSITIVITY TO MULTIPLE ALLERGENS. THERE HAVE BEEN REPORTS OF INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY WHO HAVE EXPERIENCED SEVERE REACTIONS WHEN TREATED WITH CEPHALOSPORINS. BEFORE INITIATING THERAPY WITH TIMENTIN, CAREFUL INQUIRY SHOULD BE MADE CONCERNING PREVIOUS HYPERSENSITIVITY REACTIONS TO PENICILLINS, CEPHALOSPORINS, OR OTHER ALLERGENS. IF AN ALLERGIC REACTION OCCURS, TIMENTIN SHOULD BE DISCONTINUED AND THE APPROPRIATE THERAPY INSTITUTED. SERIOUS ANAPHYLACTIC REACTIONS REQUIRE IMMEDIATE EMERGENCY TREATMENT WITH EPINEPHRINE. OXYGEN, INTRAVENOUS STEROIDS, AND AIRWAY MANAGEMENT, INCLUDING INTUBATION, SHOULD ALSO BE PROVIDED AS INDICATED.


Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including TIMENTIN, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.


C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.


If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.


When very high doses of TIMENTIN are administered, especially in the presence of impaired renal function, patients may experience convulsions. (See ADVERSE REACTIONS and OVERDOSAGE.)



Precautions



General


While TIMENTIN possesses the characteristic low toxicity of the penicillin group of antibiotics, periodic assessment of organ system functions, including renal, hepatic, and hematopoietic function, is advisable during prolonged therapy.


Bleeding manifestations have occurred in some patients receiving β-lactam antibiotics. These reactions have been associated with abnormalities of coagulation tests such as clotting time, platelet aggregation, and prothrombin time and are more likely to occur in patients with renal impairment. If bleeding manifestations appear, treatment with TIMENTIN should be discontinued and appropriate therapy instituted.


TIMENTIN has only rarely been reported to cause hypokalemia; however, the possibility of this occurring should be kept in mind particularly when treating patients with fluid and electrolyte imbalance. Periodic monitoring of serum potassium may be advisable in patients receiving prolonged therapy.


The theoretical sodium content is 4.51 mEq (103.6 mg) per gram of TIMENTIN. This should be considered when treating patients requiring restricted salt intake.


As with any penicillin, an allergic reaction, including anaphylaxis, may occur during administration of TIMENTIN, particularly in a hypersensitive individual.


The possibility of superinfections with mycotic or bacterial pathogens should be kept in mind, particularly during prolonged treatment. If superinfections occur, appropriate measures should be taken.


Prescribing TIMENTIN in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.



Information for Patients


Patients should be counseled that antibacterial drugs, including TIMENTIN, should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When TIMENTIN is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may: (1) decrease the effectiveness of the immediate treatment, and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by TIMENTIN or other antibacterial drugs in the future.


Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible.



Drug/Laboratory Test Interactions


As with other penicillins, the mixing of TIMENTIN with an aminoglycoside in solutions for parenteral administration can result in substantial inactivation of the aminoglycoside.


Probenecid interferes with the renal tubular secretion of ticarcillin, thereby increasing serum concentrations and prolonging serum half-life of the antibiotic.


In common with other antibiotics, ticarcillin disodium/clavulanate potassium may affect the gut flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives.


High urine concentrations of ticarcillin may produce false-positive protein reactions (pseudoproteinuria) with the following methods: Sulfosalicylic acid and boiling test, acetic acid test, biuret reaction, and nitric acid test. The bromphenol blue (MULTI-STIX®) reagent strip test has been reported to be reliable.


The presence of clavulanic acid in TIMENTIN may cause a nonspecific binding of IgG and albumin by red cell membranes leading to a false-positive Coombs test.



Carcinogenesis, Mutagenesis, Impairment of Fertility


Long-term studies in animals have not been performed to evaluate carcinogenic potential. However, results from assays for gene mutation in vitro using bacteria (Ames tests) and yeast, and for chromosomal effects in vitro in human lymphocytes, and in vivo in mouse bone marrow (micronucleus test) indicate that TIMENTIN is without any mutagenic potential.



Pregnancy (Category B)


Reproduction studies have been performed in rats given doses up to 1,050 mg/kg/day and have revealed no evidence of impaired fertility or harm to the fetus due to TIMENTIN. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.



Nursing Mothers


It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when TIMENTIN is administered to a nursing woman.



Pediatric Use


The safety and effectiveness of TIMENTIN have been established in the age group of 3 months to 16 years. Use of TIMENTIN in these age groups is supported by evidence from adequate and well-controlled studies of TIMENTIN in adults with additional efficacy, safety, and pharmacokinetic data from both comparative and non-comparative studies in pediatric patients. There are insufficient data to support the use of TIMENTIN in pediatric patients under 3 months of age or for the treatment of septicemia and/or infections in the pediatric population where the suspected or proven pathogen is H. influenzae type b.


In those patients in whom meningeal seeding from a distant infection site or in whom meningitis is suspected or documented, or in patients who require prophylaxis against central nervous system infection, an alternate agent with demonstrated clinical efficacy in this setting should be used.



Geriatric Use


 An analysis of clinical studies of TIMENTIN was conducted to determine whether subjects aged 65 and over respond differently from younger subjects. Of the 1,078 subjects treated with at least one dose of TIMENTIN, 67.5% were <65 years old, and 32.5% were ≥65 years old.  No overall differences in safety or efficacy were observed between these subjects and younger subjects, and other reported clinical experience have not identified differences in responses between the elderly and younger patients, but a greater sensitivity of some older individuals cannot be ruled out.


This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function (see DOSAGE and ADMINISTRATION). 


TIMENTIN contains 103.6 mg (4.51 mEq) of sodium per gram of TIMENTIN. At the usual recommended doses, patients would receive between 1,285 and 1,927 mg/day (56 and 84 mEq) of sodium. The geriatric population may respond with a blunted natriuresis to salt loading. This may be clinically important with regard to such diseases as congestive heart failure.



Adverse Reactions


As with other penicillins, the following adverse reactions may occur:



Hypersensitivity Reactions


Skin rash, pruritus, urticaria, arthralgia, myalgia, drug fever, chills, chest discomfort, erythema multiforme, toxic epidermal necrolysis, Stevens-Johnson syndrome, and anaphylactic reactions.



Central Nervous System


Headache, giddiness, neuromuscular hyperirritability, or convulsive seizures.

Trihist-D


Generic Name: pheniramine/ pyrilamine/ phenyltoloxamine/ phenylpropanolamine (fen IR a meen/pie RILL a meen/fen ill toe LOX a meen/fen ill proe pa NOLE a meen)

Brand Names: Delhist D, Delhistine D, Histine-D, Iohist D, KG-Hist D, Liqui-Histine-D, Metahistine D, Multihist D, Multihistamine-D, Poly-D, Poly-Histine-D, Prohistine-D, Trihist-D


What is Trihist-D (pheniramine/ pyrilamine/ phenyltoloxamine/ phenylpropanolamine)?

Pheniramine, pyrilamine, and phenyltoloxamine are antihistamines. They block the effects of the naturally occurring chemical histamine in the body. Pheniramine, pyrilamine, and phenyltoloxamine prevent sneezing; itchy, watery eyes and nose; and other symptoms of allergies and hay fever.


Phenylpropanolamine is a decongestant. It constricts (shrinks) blood vessels (veins and arteries). This reduces the blood flow to certain areas and allows nasal and respiratory (breathing) passages to open up.


Pheniramine/pyrilamine/phenyltoloxamine/phenylpropanolamine is used to treat nasal congestion and sinusitis (inflammation of the sinuses) associated with allergies, hay fever, and the common cold.


Phenylpropanolamine, an ingredient in this product, has been associated with an increased risk of hemorrhagic stroke (bleeding into the brain or into tissue surrounding the brain) in women. Men may also be at risk. Although the risk of hemorrhagic stroke is low, the U.S. Food and Drug Administration (FDA) recommends that consumers not use any products that contain phenylpropanolamine.


Pheniramine/pyrilamine/phenyltoloxamine/phenylpropanolamine may also be used for purposes other than those listed in this medication guide.

Sodium Sulfacetamide and Sulfur Aqueous Gel





Dosage Form: gel
10% Sodium Sulfacetamide and Sulfur 5% Aqueous Gel (in a Urea vehicle)

Rx only

DESCRIPTION:  Sodium sulfacetamide is a sulfonamide with antibacterial activity.  Sulfur acts as a keratolytic agent.  Chemically, sodium sulfacetamide is N-[(4-aminophenyl)sulfonyl]-acetamide, monosodium salt, monohydrate. The structural formula is:



Each mL of 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) contains 100 mg of sodium sulfacetamide and 50 mg of sulfur in an emulsion base containing 10% Urea, propylene glycol, isopropyl myristate, mineral oil, polysorbate 60, sorbitan monostearate, cetyl alcohol, cocoglycerides, stearyl alcohol, benzyl alcohol, glyceryl stearate and PEG 100 stearate, dimethicone, fragrance, disodium EDTA, xanthan gum, zinc pyrithione, sodium thiosulfate, purified water, magnesium aluminum silicate, and methyl paraben.



CLINICAL PHARMACOLOGY:  The most widely accepted mechanism of action of sulfonamides is the Woods-Fildes theory, which is based on the fact that sulfonamides act as competitive antagonists to para-aminobenzoic acid (PABA), an essential component for bacterial growth.  While absorption through intact skin has not been determined, sodium sulfacetamide is readily absorbed from the gastrointestinal tract when taken orally and excreted in the urine, largely unchanged.  The biological half-life has variously been reported as 7 to 12.8 hours.  The exact mode of action of sulfur in the treatment of acne is unknown, but it has been reported that it inhibits the growth of Propionibacterium acnes and the formation of free fatty acids.



INDICATIONS: 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) is indicated in the topical control of acne vulgaris, acne rosacea and seborrheic dermatitis.



CONTRAINDICATIONS: 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) is contraindicated for patients having known hypersensitivity to sulfonamides, sulfur or any other component of this preparation.  10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) is not to be used in patients with kidney disease.



WARNINGS: Rarely, sensitivity to sodium sulfacetamide may occur. Therefore, caution and careful supervision should be observed when prescribing this drug tor patients who may be prone to hypersensitivity to topical sulfonamides. Systemic toxic reactions such as agranulocytosis, acute hemolytic anemia, purpura hemorrhagica, drug fever, jaundice, and contact dermatitis indicate hypersensitivity to sulfonamides. Use particular caution on areas of denuded or abraded skin.


FOR EXTERNAL USE ONLY. Keep away from eyes.

Keep out of reach of children. Keep tube tightly closed.



PRECAUTIONS: General - If irritation develops, use of the product should be discontinued and appropriate therapy instituted.  Patients should be carefully observed for possible local irritation or sensitization during long-term therapy.  The object of this therapy is to achieve desquamation without irritation, but sodium sulfacetamide and sulfur can cause reddening  and scaling of the epidermis.  These side effects are not unusual in the treatment of acne vulgaris, but patients should be cautioned about the possibility.



Information for Patients - Avoid contact with eyes, eyelids, lips and mucous membranes. If accidental contact occurs, rinse with water. If excessive irritation develops, discontinue use and consult your physician.



Carcinogenesis, Mutagenesis and Impairment of Fertility - Long-term studies in animals have not been performed to evaluate carcinogenic potential.



Pregnancy - Category C. Animal reproduction studies have not been conducted with 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle). It is also not known whether 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) should be given to a pregnant woman only if clearly needed.



Nursing Mothers - It is not known whether sodium sulfacetamide is excreted in human milk following topical use of 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle). However, small amounts of orally administered sulfonamides have been reported to be excreted in human milk. For this reason, and because many drugs are excreted in human milk, caution should be exercised when 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) is administered to a nursing woman.



Pediatric Use: Safety and effectiveness in children under the age of 12 years have not been established.



ADVERSE REACTIONS: Rarely, sodium sulfacetamide may cause local irritation.


Call your physician for medical advice about side effects.



DOSAGE AND ADMINISTRATION:


10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle): Cleanse affected areas. Apply a thin film into affected areas 1 to 3 times daily, or as directed by a physician.

10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle): is available in a 1.5 fl. oz (45 g) tube, NDC 42808-0111-45

A single, two-gram injection produces peak serum concentrations averaging about 100 mcg/mL at one hour; a single, four-gram injection produces peak serum concentrations averaging 160 mcg/mL at two hours. Average serum concentrations of 15 mcg/mL for the two-gram dose and 31 mcg/mL for the four-gram dose were present eight hours after dosing.



Microbiology


Spectinomycin hydrochloride is an inhibitor of protein synthesis in the bacterial cell; the site of action is the 30S ribosomal subunit.


In vitro studies have shown spectinomycin hydrochloride to be active against most strains of Neisseria gonorrhoeae (minimum inhibitory concentration <7.5 to 20 mcg/mL).


Definitive in vitro studies have shown no cross-resistance of N. gonorrhoeae between spectinomycin hydrochloride and penicillin. The antibiotic is not significantly bound to plasma protein.



Indications and Usage for Trobicin


Trobicin Sterile Powder is indicated in the treatment of acute gonorrheal urethritis and proctitis in the male and acute gonorrheal cervicitis and proctitis in the female when due to susceptible strains of Neisseria gonorrhoeae. Men and women with known recent exposure to gonorrhea should be treated as those known to have gonorrhea.


The in vitro susceptibility of Neisseria gonorrhoeae to spectinomycin hydrochloride can be tested by agar diluted methods. Trobicin Susceptibility Powder is available for this purpose and its package insert should be consulted for details.


To reduce the development of drug-resistant bacteria and maintain the effectiveness of Trobicin Sterile Powder and other antibacterial drugs, Trobicin Sterile Powder should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.



Contraindications


The use of Trobicin Sterile Powder is contraindicated in patients previously found hypersensitive to it.



Warnings


Spectinomycin hydrochloride is not effective in the treatment of syphilis. Antibiotics used in high doses for short periods of time to treat gonorrhea may mask or delay the symptoms of incubating syphilis. Since the treatment of syphilis demands prolonged therapy with any effective antibiotic, patients being treated for gonorrhea should be closely observed clinically. All patients with gonorrhea should have a serologic test for syphilis at the time of diagnosis. Patients treated with spectinomycin hydrochloride should have a follow-up serologic test for syphilis after three months.


Contains benzyl alcohol. Benzyl alcohol has been reported to be associated with a fatal "Gasping Syndrome" in premature infants and an increased incidence of neurologic and other complications.



Precautions


The usual precautions should be observed with atopic individuals.


The clinical effectiveness of Trobicin Sterile Powder should be monitored to detect evidence of development of resistance by Neisseria gonorrhoeae.


Prescribing Trobicin Sterile Powder in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.



Information for Patients


Patients should be counseled that antibacterial drugs including Trobicin Sterile Powder should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Trobicin Sterile Powder is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Trobicin Sterile Powder or other antibacterial drugs in the future.



Carcinogenesis, Mutagenesis, Impairment of Fertility


Genotoxicity of spectinomycin hydrochloride was evaluated in six assay test systems including two Ames tests, two micronucleus tests in mice, unscheduled DNA synthesis in rat primary hepatocytes, and a chromosomal aberration test in Chinese hamster ovary cells. Spectinomycin was not shown to be mutagenic or genotoxic in these tests.


No adverse effects on fertility or general reproductive performance were observed when spectinomycin was administered subcutaneously to rats at dose levels up to 300 mg/kg (equivalent to the recommended maximum human dose based on mg/m2). A three-generation reproduction study in rats administered spectinomycin hydrochloride orally at dose levels up to 400 mg/kg (equivalent to the recommended maximum human dose based on mg/m2) produced no evidence of drug-induced toxicity during growth, gestation, or lactation periods of any parental generation. Pregnancy rates of the 400 mg/kg/day groups were consistently lower than those of the control groups. A histopathological examination of the testes and ovaries of the third generation animals was normal.



Pregnancy


Teratogenic Effects

Pregnancy Category B


Spectinomycin was not teratogenic or embryocidal when orally or subcutaneously administered to rats at doses of 300 mg/kg/day (equivalent to the recommended maximum human dose based on mg/m2). No teratogenic effects were observed when spectinomycin was administered intraperitoneally to mice or rats at dose levels of 400 or 1600 mg/kg/day, respectively. Spectinomycin was administered intramuscularly or subcutaneously to pregnant rabbits at dose levels up to 300 mg/kg/day (equivalent to the recommended maximum human dose based on mg/m2). Embryonic and fetal development were unaffected by treatment. Since there are no controlled studies of spectinomycin in pregnant women, and because animal reproduction studies are not always predictive of human responses, spectinomycin should be used during pregnancy only if clearly needed.



Nursing Mothers


It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when spectinomycin is administered to a nursing woman.



Pediatric Use


Safety and effectiveness in the pediatric population have not been established. (See WARNINGS.)



Adverse Reactions


The following reactions were observed during the single dose clinical trials: soreness at the injection site, urticaria, dizziness, nausea, chills, fever and insomnia.


During multiple dose subchronic tolerance studies in normal human volunteers, the following were noted: a decrease in hemoglobin, hematocrit and creatinine clearance; elevation of alkaline phosphatase, BUN and SGPT. In single and multiple dose studies in normal volunteers, a reduction in urine output was noted. Extensive renal function studies demonstrated no consistent changes indicative of renal toxicity.


A few cases of anaphylaxis or anaphylactoid reactions have been reported. If serious allergic reactions occur, the usual agents (epinephrine, corticosteroids, and/or antihistamines) should be available for emergency use. In cases of severe anaphylaxis, airway support and oxygen may also be required.



Overdosage


Information on overdosage in humans is not available. Hemodialysis has been reported to aid in the removal of intravenously administered spectinomycin from the body.

What is Stalevo 150 (carbidopa, entacapone, and levodopa)?

Levodopa is converted to a chemical called dopamine (DOE pa meen) in the brain. Symptoms of Parkinson's disease may be caused by low levels of dopamine in the brain. Carbidopa helps prevent the breakdown of levodopa before it can reach the brain and take effect. Entacapone increases levels of levodopa in the body.


The combination of carbidopa, entacapone, and levodopa is used to treat Parkinson symptoms such as muscle stiffness, tremors, spasms, and poor muscle control.


Carbidopa, entacapone, and levodopa may also be used for purposes not listed in this medication guide.
