Galaxy® (PL 2040) Plastic Container
(Product Package)
Timentin is an injectable antibacterial combination consisting of the semisynthetic antibiotic, ticarcillin disodium, and the (beta)-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.
Clavulanic acid is produced by the fermentation of Streptomyces clavuligerus . It is a (beta)-lactam structurally related to the penicillins and possesses the ability to inactivate a wide variety of (beta)-lactamases by blocking the active sites of these enzymes. Clavulanic acid is particularly active against the clinically important plasmid-mediated (beta)-lactamases frequently responsible for transferred drug resistance to penicillins and cephalosporins.
Chemically, clavulanate potassium is potassium (Z)-(2 R ,5 R )-3-(2-hydroxyethylidene)-7-oxo- 4-oxa-1- azabicyclo[3.2.0] heptane-2-carboxylate.
Timentin is an iso-osmotic, sterile, nonpyrogenic, frozen solution consisting of 3.0 grams ticarcillin as ticarcillin disodium and 0.1 gram clavulanic acid as clavulanate potassium. Approximately 0.3 gram sodium citrate hydrous, USP, is added as a buffer. Sodium hydroxide is used to adjust pH and convert ticarcillin monosodium to ticarcillin disodium. The pH may have been adjusted with hydrochloric acid. The solution is intended for intravenous use after thawing to room temperature. The pH of thawed solution ranges from 5.5 to 7.5.
For the Timentin 3.1 gram in the Galaxy® (PL 2040) Plastic Container, the theoretical total sodium content of the 100 mL solution is 18.7 mEq (429 mg), of which 15.6 mEq (359 mg) is contributed by the ticarcillin disodium component of Timentin . The total theoretical potassium content of the 100 mL solution is 0.50 mEq (19.63 mg).
This plastic container is fabricated from a specially designed multilayer plastic (PL 2040). Solutions are in contact with the polyethylene layer of this container and can leach out certain chemical components of the plastic in very small amounts within the expiration period. The suitability of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers, as well as by tissue culture toxicity studies.
After an intravenous infusion (30 min.) of 3.1 grams Timentin , peak serum concentrations of both ticarcillin and clavulanic acid are attained immediately after completion of the 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 324 µg/mL for the 3.1 gram formulation. The mean peak serum level for clavulanic acid is 8 µg/mL for the 3.1 gram formulation. (See following table.)
|
The mean area under the serum concentration curve was 485 µg.hr./mL for ticarcillin and 8.2 µg.hr./mL for clavulanic acid in the Timentin 3.1 gram formulation.
The mean serum half-lives of ticarcillin and clavulanic acid in healthy volunteers are 1.1 hours and 1.1 hours, respectively, following administration of 3.1 grams of Timentin .
In pediatric patients receiving approximately 50 mg/kg 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 µg.hr./mL in infants and children (n=41), whereas the corresponding mean clavulanate area under the serum concentration time curves was approximately 7 µg.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 Timentin , concentrations of ticarcillin in urine generally exceed 1500 µg/mL. The corresponding concentration of clavulanic acid in urine generally exceeds 40 µg/mL. By 4 to 6 hours after injection, the urine concentrations of ticarcillin and clavulanic acid usually decline to approximately 190 µg/mL and 2 µg/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 9% 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.
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 (beta)-lactamases and, therefore, the spectrum of activity does not normally include organisms which produce these enzymes.
Clavulanic acid is a (beta)-lactam, structurally related to the penicillins, which possesses the ability to inactivate a wide range of (beta)-lactamase enzymes commonly found in microorganisms resistant to penicillins and cephalosporins. In particular, it has good activity against the clinically important plasmid-mediated (beta)-lactamases frequently responsible for transferred drug resistance.
The formulation of ticarcillin with clavulanic acid in Timentin protects ticarcillin from degradation by (beta)-lactamase enzymes and effectively extends the antibiotic spectrum of ticarcillin to include many bacteria normally resistant to ticarcillin and other (beta)-lactam antibiotics. Thus Timentin possesses the distinctive properties of a broad-spectrum antibiotic and a (beta)-lactamase inhibitor.
While in vitro studies have demonstrated the susceptibility of most strains of the following organisms, clinical efficacy for infections other than those included in the INDICATIONS AND USAGE section has not been documented.
GRAM-NEGATIVE BACTERIA : Pseudomonas aeruginosa ((beta)-lactamase and non-(beta)-lactamase producing), Pseudomonas species including P. maltophilia ((beta)-lactamase and non-(beta)-lactamase producing), Escherichia coli ((beta)-lactamase and non-(beta)-lactamase producing), Proteus mirabilis ((beta)-lactamase and non-(beta)-lactamase producing), Proteus vulgaris ((beta)-lactamase and non-(beta)-lactamase producing), Providencia rettgeri (formerly Proteus rettgeri ) ((beta)-lactamase and non-(beta)-lactamase producing), Providencia stuartii ((beta)-lactamase and non-(beta)-lactamase producing), Morganella morganii (formerly Proteus morganii ) ((beta)-lactamase and non-(beta)-lactamase producing), Enterobacter species (Although most strains of Enterobacter species are resistant in vitro , clinical efficacy has been demonstrated with Timentin in urinary tract infections caused by these organisms.), Acinetobacter species ((beta)-lactamase and non-(beta)-lactamase producing), Haemophilus influenzae ((beta)-lactamase and non-(beta)-lactamase producing), Moraxella ( Branhamella ) catarrhalis ((beta)-lactamase and non-(beta)-lactamase producing), Serratia species including S. marcescens ((beta)-lactamase and non-(beta)-lactamase producing), Neisseria gonorrhoeae ((beta)-lactamase and non-(beta)-lactamase producing), Neisseria meningitidis * , Salmonella species ((beta)-lactamase and non-(beta)-lactamase producing), Klebsiella species including K. pneumoniae ((beta)-lactamase and non- (beta)-lactamase producing), Citrobacter species including C. freundii, C. diversus and C. amalonaticus ((beta)-lactamase and non-(beta)-lactamase producing).
GRAM-POSITIVE BACTERIA : Staphylococcus aureus ((beta)-lactamase and non-(beta)-lactamase producing), Staphylococcus saprophyticus, Staphylococcus epidermidis (coagulase-negative staphylococci) ((beta)-lactamase and non-(beta)-lactamase producing), Streptococcus pneumoniae * ( D. pneumoniae ), Streptococcus bovis * , Streptococcus agalactiae * (Group B), Enterococcus faecalis * (formerly Streptococcus faecalis ), Streptococcus pyogenes * (Group A, (beta)-hemolytic), Viridans group streptococci * .
ANAEROBIC BACTERIA : Bacteroides species, including B. fragilis group ( B. fragilis, B. vulgatus ) ((beta)-lactamase and non-(beta)-lactamase producing), non- B. fragilis beta melaninogenicus ) ((beta)-lactamase and non-(beta)-lactamase producing), B. thetaiotaomicron, B. ovatus, B. distasonis ((beta)-lactamase and non-(beta)-lactamase-producing), Clostridium species including C. perfringens, C. difficile, C. sporogenes, C. ramosum and C. bifermentans * , Eubacterium species Fusobacterium species including F. nucleatum and F. necrophorum * , Peptococcus species * , Peptostreptococcus species * , Veillonella species
In vitro synergism between Timentin and gentamicin, tobramycin or amikacin against multiresistant strains of Pseudomonas aeruginosa has been demonstrated.
Diffusion Technique: An 85 mcg Timentin (75 mcg ticarcillin plus 10 mcg clavulanic acid) diffusion disk is available for use with the Kirby-Bauer method. 1 Based on the zone sizes given below, a report of "Susceptible" indicates that the infecting organism is likely to respond to Timentin therapy, while a report of "Resistant" indicates that the organism is not likely to respond to therapy with this antibiotic. A report of "Intermediate" susceptibility indicates that the organism would be susceptible to Timentin at a higher dosage or if the infection is confined to tissues or fluids (e.g., urine) in which high antibiotic levels are attained.
Dilution Technique: Broth or agar dilution methods 2 may be used to determine the minimal inhibitory concentration (MIC) values for bacterial isolates to Timentin . Tubes should be inoculated with the test culture containing 10 4 to 10 5 CFU/mL or plates spotted with a test solution containing 10 3 to 10 4 CFU/mL.
The recommended dilution pattern utilizes a constant level of clavulanic acid, 2 mcg/mL, in all tubes together with varying amounts of ticarcillin. MICs are expressed in terms of the ticarcillin concentration in the presence of 2 mcg/mL clavulanic acid.

Timentin is indicated in the treatment of infections caused by susceptible strains of the designated organisms in the conditions listed below:
Septicemia , including bacteremia, caused by (beta)-lactamase-producing strains of Klebsiella spp. * , E. coli * , Staphylococcus aureus * , or Pseudomonas aeruginosa * (or other Pseudomonas species * )
Lower Respiratory Infections caused by (beta)-lactamase-producing strains of Staphylococcus aureus, Haemophilus influenzae * , or Klebsiella spp. *

Intra-abdominal Infections peritonitis caused by (beta)-lactamase-producing strains of Escherichia coli, Klebsiella pneumoniae , or Bacteroides fragilis * group
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 Haemophilus influenzae type b.
While Timentin is indicated only for the conditions listed above, infections caused by ticarcillin-susceptible organisms are also amenable to Timentin treatment due to its ticarcillin content. Therefore, mixed infections caused by ticarcillin-susceptible organisms and (beta)-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 (beta)-lactamase-producing organisms listed above; however, once these results become available, appropriate therapy should be continued. Based on the in vitro synergism between ticarcillin/clavulanic acid and aminoglycosides against certain strains of Pseudomonas aeruginosa , combined therapy has been successful, especially in patients with impaired host defenses. Both drugs should be used in full therapeutic doses. As soon as results of culture and susceptibility tests become available, antimicrobial therapy should be adjusted as indicated.
Timentin is contraindicated in patients with a history of hypersensitivity reactions to any of the penicillins.
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. Pseudomembranous colitis has been reported with nearly all antibacterial agents, including Timentin , and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.
Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is a primary cause of "antibiotic-associated colitis."
After the diagnosis of pseudomembranous colitis has been established, appropriate therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation and treatment with an antibacterial drug clinically effective against Clostridium difficile colitis
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 .)
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 (beta)-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, Timentin treatment 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 total sodium content of the 100 mL premixed solution is 429 mg (359 mg contributed by the ticarcillin disodium component 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 Timentin administration, 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.
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.
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 lgG 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 1050 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 Haemophilus influenzae type b. The potential for toxic effects in children from chemicals that may leach from the single dose premixed intravenous preparation in plastic containers has not been determined.
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.
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
Gastrointestinal disturbances: disturbances of taste and smell, stomatitis, flatulence, nausea, vomiting and diarrhea, epigastric pain, and pseudomembranous colitis have been reported. Onset of pseudomembranous colitis symptoms may occur during or after antibiotic treatment. (See WARNINGS .)
Hematologic system: thrombocytopenia, leukopenia, neutropenia, eosinophilia, reduction of hemoglobin or hematocrit, and the prolongation of prothrombin time and bleeding time
Abnormalities of hepatic and renal function tests: elevation of serum aspartate aminotransferase (SGOT), serum alanine aminotransferase (SGPT), serum alkaline phosphatase, serum LDH, serum bilirubin. There have been reports of transient hepatitis and cholestatic jaundice--as with some other penicillins and some cephalosporins. Elevation of serum creatinine and/or BUN, hypernatremia, reduction in serum potassium and uric acid
Local reactions: pain, burning, swelling, and induration at the infusion site and thrombophlebitis.
Available safety data for pediatric patients treated with Timentin demonstrate a similar adverse event profile to that observed in adult patients.
Neither Timentin abuse nor Timentin dependence has been reported.
As with other penicillins, neurotoxic reactions may arise when very high doses of Timentin are administered, especially in patients with impaired renal function. (See WARNINGS and ADVERSE REACTIONS -- Central nervous system .)
In case of overdosage, discontinue Timentin , treat symptomatically, and institute supportive measures as required. Ticarcillin may be removed from circulation by hemodialysis. The molecular weight, degree of protein binding, and pharmacokinetic profile of clavulanic acid together with information from a single patient with renal insufficiency all suggest that this compound may also be removed by hemodialysis.
Timentin should be administered by intravenous infusion (30 min.).
Adults: The usual recommended dosage for systemic and urinary tract infections for average (60 kg) adults is 3.1 grams Timentin (3 grams ticarcillin and 100 mg clavulanic acid) given every 4 to 6 hours. For gynecologic infections, Timentin should be administered as follows: Moderate infections 200 mg/kg/day in divided doses every 6 hours and for severe infections 300 mg/kg/day in divided doses every 4 hours. For patients weighing less than 60 kg, the recommended dosage is 200-300 mg/kg/day, based on ticarcillin content, given in divided doses every 4 to 6 hours.
For patients <60 kg:
In patients <60 kg, Timentin is dosed at 50 mg/kg/dose based on the ticarcillin component. Timentin should be administered as follows: Mild to moderate infections 200 mg/kg/day in divided doses every 6 hours; for severe infections, 300 mg/kg/day in divided doses every 4 hours.
For patients >/=60 kg:
For mild to moderate infections, 3.1 grams Timentin (3 grams of ticarcillin and 100 mg of clavulanic acid) administered every 6 hours; for severe infections, 3.1 grams every 4 hours.
For infections complicated by renal insufficiency , an initial loading dose of 3.1 grams should be followed by doses based on creatinine clearance and type of dialysis as indicated below:
|
Dosage for any individual patient must take into consideration the site and severity of infection, the susceptibility of the organisms causing infection, and the status of the patient' host defense mechanisms.
The duration of therapy depends upon the severity of infection. Generally, Timentin should be continued for at least two days after the signs and symptoms of infection have disappeared. The usual duration is 10 to 14 days; however, in difficult and complicated infections, more prolonged therapy may be required.
Frequent bacteriologic and clinical appraisals are necessary during therapy of chronic urinary tract infection and may be required for several months after therapy has been completed. Persistent infections may require treatment for several weeks and doses smaller than those indicated above should not be used.
In certain infections, involving abscess formation, appropriate surgical drainage should be performed in conjunction with antimicrobial therapy.

Timentin has been studied in a total of 296 pediatric patients (excluding neonates and infants less than 3 months) in six controlled clinical trials. The majority of patients studied had intra-abdominal infections, and the primary comparator was clindamycin and gentamycin with or without ampicillin. At the end-of-therapy visit, comparable efficacy was reported in the Timentin and appropriate comparator arms.
Timentin was also evaluated in an additional 408 pediatric patients (excluding neonates and infants less than 3 months) in three uncontrolled U.S. clinical trials. Patients were treated across a broad range of presenting diagnoses including: infections in bone and joint, skin and skin structure, lower respiratory tract, urinary tract, as well as intra-abdominal and gynecologic infections. Patients received Timentin either 300 mg/kg/day (based on the ticarcillin component) divided q4h for severe infection or 200 mg/kg/day (based on the ticarcillin component) divided q6h for mild to moderate infections. The efficacy rates were comparable to those obtained in the controlled trials.
The adverse event profile in these 704 Timentin -treated pediatric patients was comparable to that seen in adult patients.
