Tripenem 1 injection is used to treat infections caused by bacteria. It works by killing the bacteria or preventing their growth. Tripenem 1 will not work for colds, flu, or other virus infections.
Tripenem 1 is to be given only by or under the direct supervision of your doctor.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, Tripenem 1 is used in certain patients with the following medical condition:
Febrile neutropenia (treatment).
Tripenem 1 indications
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Tripenem 1 I.V. and other antibacterial drugs, Tripenem 1 I.V. should only be used 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.
Tripenem 1 I.V. is useful as presumptive therapy in the indicated condition (e.g., intra-abdominal infections) prior to the identification of the causative organisms because of its broad spectrum of bactericidal activity.
For information regarding use in pediatric patients [seeIndications and Usage (1.1), (1.2), (1.3), Dosage and Administration (2.3), Adverse Reactions (6.1), andClinical Pharmacology (12.3)].

The molecular formula of Tripenem 1 trihydrate is C17H25N3O5S·3H2O and its CAS number is 119478-56-7.
DBL Tripenem 1 for Injection is presented as a sterile white to pale yellow crystalline powder containing Tripenem 1 trihydrate equivalent to Tripenem 1, 500 mg or 1 g, blended with sodium carbonate anhydrous. DBL Tripenem 1 for Injection contains 208 mg sodium carbonate anhydrous and 90.2 mg of sodium for each gram of Tripenem 1 (anhydrous potency). It contains no antimicrobial preservative and is for use in one patient on one occasion only..
Tripenem 1 dosage
Adults: The recommended dose of Tripenem 1 injection of 500 mg is given every 8 hours for a skin and skin structure infections when treating infections caused by Pseudomonas aeruginosa, dose of 1 gram every 8 hours is recommended, and 1 gram given every 8 hours for intra-abdominal infections. Tripenem 1 injection should be administered by intravenous infusion over approximately 15 to 30 minutes. Doses of 1 gram every 8 hours may also be administered as an intravenous bolus injection (5 to 20 mL) over approximately 3-5 minutes.
Renal Impairment:Dosage should be reduced in patients with creatinine clearance less than 51 mL/min.
When only serum creatinine is available, the following formula (Cockroft and Gault equation) may be used to estimate creatinine clearance.
There is inadequate information regarding the use of Tripenem 1 in patients on hemodialysis. There is no experience with peritoneal dialysis.
Hepatic Impairment: No dosage adjustment is necessary in patients with impaired hepatic function.
Elderly: No dosage adjustment is required for elderly patients with creatinine clearance values above 50 mL/min.
Children: For pediatric patients from 3 months of age and older, the Tripenem 1 injection, dose is 10, 20 or 40 mg/kg every 8 hours (maximum dose is 2 g every 8 hours), depending on the type of infection (complicated skin and skin structure infections, intra-abdominal or meningitis). Pediatric patients weighing over 50 kg should be administered Tripenem 1 injection at a dose of 500 mg every 8 hours for complicated skin and skin structure infections, 1 g every hour for intra-abdominal infections and 2 g every 8 hours for meningitis. Tripenem 1 injection, should be given as intravenous infusion over approximately 15 to 30 minutes or as an intravenous bolus injection (5 to 20 mL) infusion over approximately 3-5 minutes. There is limited safety data available to support the administration of a 40 mg/kg (up to a maximum of 2 g) bolus dose.
Probenecid competes with Tripenem 1 for active tubular secretion and thus inhibits the renal excretion, with the effect of increasing the elimination half-life and plasma concentration of Tripenem 1. As the potency and duration of action of Tripenem 1 dosed without probenecid are adequate, the co-administration of probenecid with Tripenem 1 is not recommended.
The potential effect of Tripenem 1 on the protein-binding of other drugs or metabolism has not been studied. The protein binding of Tripenem 1 is low (approximately 2%) and, therefore, no interactions with other compounds based on displacement from plasma proteins would be expected.
Tripenem 1 may reduce serum valproic acid levels. Subtherapeutic levels may be reached in some patients.
Tripenem 1 has been administered concomitantly with other medications without adverse pharmacological interactions. However, no specific data regarding potential drug interactions is available (apart from probenecid as previous;y mentioned).
Decreases in blood levels of valproic acid have been reported when it is co-administered with carbapenem agents resulting in a 60-100% decrease in valproic acid levels in about 2 days. Due to the rapid onset and the extent of the decrease, co-administration of Tripenem 1 in patients stabilised on valproic acid is not considered to be manageable and therefore should be avoided.
Simultaneous administration of antibiotics with warfarin may augment its anticoagulant effects. There have been many reports of increases in the anticoagulant effects of orally administered anticoagulant agents, including warfarin in patients who are concomitantly receiving antibacterial agents. The risk may vary with the underlying infection, age and general status of the patient so that the contribution of the antibiotic to the increase in international normalised ratio (INR) is difficult to assess. It is recommended that the INR should be monitored frequently during and shortly after co-administration of antibiotics with an oral anticoagulant agent.
Incompatibilities: Tripenem 1 must not be mixed with other medicinal products except those mentioned in Cautions for Usage.
