What is Meropenem?

Meropenem injection is used to treat infections caused by bacteria. It works by killing the bacteria or preventing their growth. Meropenem will not work for colds, flu, or other virus infections.

Meropenem 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, Meropenem is used in certain patients with the following medical condition:

Meropenem 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 Meropenem I.V. and other antibacterial drugs, Meropenem 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.

Meropenem 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)].

Skin and Skin Structure Infections (Adult Patients and Pediatric Patients 3 Months of Age and Older Only)

Meropenem I.V. is indicated as a single agent therapy for the treatment of complicated skin and skin structure infections due to Staphylococcus aureus (methicillin-susceptible isolates only), Streptococcus pyogenes, Streptococcus agalactiae, viridans group streptococci, Enterococcus faecalis (vancomycin-susceptible isolates only), Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis, Bacteroides fragilis, and Peptostreptococcus species.

Intra-abdominal Infections (Adult and Pediatric Patients)

Meropenem I.V. is indicated as a single agent therapy for the treatment of complicated appendicitis and peritonitis caused by viridans group streptococci, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Bacteroides fragilis, B. thetaiotaomicron, and Peptostreptococcus species.

Bacterial Meningitis (Pediatric Patients 3 Months of Age and Older Only)

Meropenem I.V. is indicated as a single agent therapy for the treatment of bacterial meningitis caused by Streptococcus pneumoniae‡, Haemophilus influenzae, and Neisseria meningitidis.

‡ The efficacy of Meropenem as monotherapy in the treatment of meningitis caused by penicillin nonsusceptible isolates of Streptococcus pneumoniae has not been established.

Meropenem I.V. has been found to be effective in eliminating concurrent bacteremia in association with bacterial meningitis.

How should I use Meropenem?

Use Meropenem as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Ask your health care provider any questions you may have about how to use Meropenem.

Uses of Meropenem in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Meropenem dosage

sponsored

Adults: The recommended dose of Meropenem 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. Meropenem 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 Meropenem 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 Meropenem 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 Meropenem 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. Meropenem 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.

Meropenem interactions

What other drugs will affect Meropenem?

Probenecid competes with Meropenem for active tubular secretion and thus inhibits the renal excretion, with the effect of increasing the elimination half-life and plasma concentration of Meropenem. As the potency and duration of action of Meropenem dosed without probenecid are adequate, the co-administration of probenecid with Meropenem is not recommended.

The potential effect of Meropenem on the protein-binding of other drugs or metabolism has not been studied. The protein binding of Meropenem is low (approximately 2%) and, therefore, no interactions with other compounds based on displacement from plasma proteins would be expected.

Meropenem may reduce serum valproic acid levels. Subtherapeutic levels may be reached in some patients.

Meropenem 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 Meropenem in patients stabilised on valproic acid is not considered to be manageable and therefore should be avoided.

Oral Anticoagulants:

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: Meropenem must not be mixed with other medicinal products except those mentioned in Cautions for Usage.
