Meropenem

Drug overview for MEROPENEM (meropenem):

Generic name: MEROPENEM (MER-oh-PEN-em)
Drug class: Beta-Lactams
Therapeutic class: Anti-Infective Agents

Meropenem is a synthetic carbapenem beta-lactam antibiotic that is structurally and pharmacologically related to imipenem, but does not require concomitant administration with a dehydropeptidase 1 (DHP 1) inhibitor such as cilastatin.

Meropenem is used for the treatment of intra-abdominal infections, meningitis, and skin and skin structure infections caused by susceptible bacteria. The drug also is used for the treatment of respiratory tract infections+, septicemia+, and urinary tract infections+ caused by susceptible bacteria and for empiric anti-infective therapy in febrile neutropenic patients+. Prior to initiation of meropenem therapy, appropriate specimens should be obtained for identification of the causative organism and in vitro susceptibility tests.

Meropenem can be initiated empirically pending completion of susceptibility testing, with continuance or alteration (e.g., substitution of an appropriate alternative anti-infective) determined by the results of culture and susceptibility tests.

The following dosing information is available for MEROPENEM (meropenem):

Dosing
Administration
MEROPENEM
MEROPENEM

Meropenem is commercially available as the trihydrate; potency and dosage of the drug are expressed on the anhydrous basis.

To minimize the risk of seizures, recommended meropenem dosage should not be exceeded, especially in patients with factors known to predispose to seizure activity. (See CNS Effects under Warning/Precautions: Warnings, in Cautions.)

Children weighing more than 50 kg should receive the usually recommended adult dosage of meropenem.

The manufacturer states that dosage adjustment is not necessary for geriatric patients with creatinine clearances exceeding 50 mL/minute. For geriatric patients with reduced renal function, dosage should be adjusted according to the guidelines for other adults with renal impairment. (See Dosage in Renal and Hepatic Impairment under Dosage and Administration: Dosage.)

Dosage of meropenem should be modified according to the degree of renal impairment in adults with creatinine clearances of 50 mL/minute or less. The manufacturer and some clinicians recommend that adults with creatinine clearances of 26-50 mL/minute can receive the usual dose every 12 hours, those with creatinine clearances of 10-25 mL/minute can receive half the usual dose every 12 hours, and those with creatinine clearances less than 10 mL/minute can receive half the usual dose every 24 hours. If a measured creatinine clearance is unavailable, the patient's creatinine clearance (Ccr) can be estimated using the following formulas:

Because meropenem is removed by hemodialysis, supplemental doses should be given after each hemodialysis session. Meropenem also is removed by various forms of continuous renal replacement therapy, including continuous venovenous hemodiafiltration (CVVHDF), continuous venovenous hemofiltration (CVVHF), and continuous ambulatory peritoneal dialysis (CAPD). Therefore, to avoid inadequate meropenem concentrations in anuric patients undergoing these procedures, dosage adjustments are necessary and should be based on characteristics of the specific procedure (e.g., filter or membrane type, amount of filtrate produced, dialysate flow rate).

The manufacturer states that there is a lack of experience with use of meropenem in pediatric patients with renal impairment. Some clinicians suggest that pediatric patients undergoing hemodialysis receive meropenem doses after hemodialysis.

Dosage adjustment is not necessary in patients with hepatic impairment.

Meropenem is administered by IV injection or IV infusion.

Drug Interaction	Drug Names
Live Typhoid Vaccine/Antimicrobials SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient. MECHANISM OF ACTION: The antimicrobial may be active against the organism in the live-vaccine. Antimicrobial therapy may prevent the vaccine organism from replicating enough to trigger an immune response.(1) CLINICAL EFFECTS: Vaccination may be ineffective. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Do not give oral typhoid vaccine until 72 hours after the last dose of antimicrobial. If possible, to optimize vaccine effectiveness, do not start antibacterial drugs for 72 hours after the last dose of oral typhoid vaccine. A longer interval should be considered for long-acting antimicrobials, such as azithromycin.(3) DISCUSSION: Because antimicrobial therapy may prevent sufficient vaccine-organism replication to generate an immune response, the manufacturer of live-attenuated typhoid vaccine and the Centers for Disease Control (CDC) state that the vaccine should not be administered to patients receiving antimicrobial therapy.(1-3)	VIVOTIF

There are 3 severe interactions. These drug interactions can produce serious consequences in most patients. Actions required for severe interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration scheduling, and providing additional patient monitoring. Review the full interaction monograph for more information.

Drug Interaction	Drug Names
Valproic Acid/Carbapenem Antibiotics SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: The exact mechanism is unknown. Carbapenems may inhibit the absorption of valproic acid from the gastrointestinal tract.(1-3) Meropenem may accelerate the renal excretion of valproate.(4) Carbapenems may increase valproic acid intake by erythrocytes.(5,6) Carbapenems may inhibit the metabolite of valproic acid, valproic acid-glucuronide, from being converted back into the active parent form.(7-9) CLINICAL EFFECTS: Concurrent use of carbapenems and valproic acid without supplemental antiepileptic therapy is not recommended because it results in rapid, significant reductions in serum levels of valproic acid to non-therapeutic levels which may result in seizures. Dose escalation of valproic acid formulations does not counteract the decrease in serum levels and patients will require additional antiepileptic therapy. The effects may persist for several days beyond discontinuation of the carbapenem. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Avoid the use of carbapenem antibiotics in patients maintained on valproic acid when possible. If concurrent therapy is warranted, patients will require the addition of a supplemental anti-epileptic agent until valproic acid levels return to therapeutic range. DISCUSSION: In a retrospective review of an 18 month period, charts of 39 patients who received concurrent therapy with valproate and meropenem were examined. A pharmacokinetic interaction was observed in all 39 patients, with an average decrease in valproate levels of 66%. The decrease occurred within 24 hours of the initiation of concurrent therapy. Electroclinical deterioration was seen in 55% of patients.(10) A prospective study evaluated ICU patients given levetiracetam or valproic acid to control seizures. Twenty-four of the 35 patients required meropenem. Each patient that was on valproic acid had valproic acid levels decrease following the addition of meropenum. (13) In a study in 23 healthy male subjects, concurrent doripenem (500 mg every 8 hours) decreased the maximum concentration, (Cmax) area-under-curve (AUC), and minimum concentration (Cmin) of valproic acid by 44.5%, 63% and 77.7%, respectively.(14) There are several case reports of decreased valproic acid levels following the addition of meropenem to therapy.(4,11,12,15-21) Some patients experienced increased seizures.(4 ,11,15,16,20) In some cases, decreased levels persisted despite increased doses of valproic acid.(11,12,15,17,18,21) Others required additional anti-seizure medications during concurrent therapy.(16) Decreased valproic acid levels have also been reported during concurrent ertapenem.(22-25) Seizures were reported in two patients.(22,25) In one patient, valproic acid levels returned to therapeutic levels within three days of discontinuation of ertapenem, despite no change in valproic acid dose.(25) Decreased valproic acid levels have also been reported during concurrent imipenem.(26) A retrospective study evaluated 52 patients given valproic acid and a carbapenem over a five year period. Patients received either ertapenem, imipenem/cilastatin, or meropenem (9, 17, and 26 patients, respectively). The average serum valproic acid concentration before and after carbapenem use was 58.6 +/- 19.2 and 23.7 +/- 16.3 mg/dL, respectively, which represented a decrease of 60% +/- 23% (p<0.001). Valproic acid concentrations were reduced with both intravenous and oral formulations of valproic acid (52% +/- 16% and 61% +/-24%, respectively). Valproic acid serum concentrations were subtherapeutic (<50 mg/L) in 90% of patients during carbapenem concurrent use. Use during ertapenem, imipenem/cilastatin, and meropenem decreased valproic acid concentrations by 72% +/- 17%, 42% +/- 22%, and 67% +/- 19%, respectively.(28) A retrospective study in 54 patients treated with valproic acid for at least three months for seizure control were evaluated for changes in valproic acid with concurrent carbapenem therapy. The mean change in valproic acid levels was 80%, 68%, and 51% in the meropenem, ertapenem, and imipenem group, respectively. During concurrent therapy, 48.1% of patients experienced aggravation of seizures and 25.9% died. Valproic acid levels of those experiencing aggravation of seizures were 17.7 +/- 9.9 mcg/mL versus 17.9 +/- 12.6 mcg/mL in those without aggravation (p=0.944).(29) A retrospective study in 381 neurosurgery inpatients evaluated valproic acid levels with concurrent meropenem therapy. Patients were grouped based on valproic acid dose of 1.2 g/day or 1.6 g/day with and without meropenem. In both 1.2 g/day and 1.6 g/day valproic acid groups, valproic acid levels were decreased after initiation of meropenem (67.3 +/- 4.6 mcg/mL v. 15.3 +/- 1.9 mcg/mL; 78.2% decrease, p<0.001 for 1.2 g/day valproic acid; 67.6 +/- 1.2 mcg/mL v. 18.1 +/- 2.6 mcg/mL; 72.5% decrease, p<0.001 for 1.6 g/day valproic acid. Valproic acid concentrations recovered to levels comparable to valproic acid alone more than seven days after meropenem discontinuation.(30)	DEPAKOTE, DEPAKOTE ER, DEPAKOTE SPRINKLE, DIVALPROEX SODIUM, DIVALPROEX SODIUM ER, SODIUM VALPROATE, VALPROATE SODIUM, VALPROIC ACID
Doripenem; Meropenem/OAT3 Inhibitors SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Inhibitors of organic anion transporter 3 (OAT3) may inhibit the renal excretion of doripenem (1) and meropenem(2) by competing with them for active tubular secretion. CLINICAL EFFECTS: Concurrent use of organic anion transporter 3 (OAT3) inhibitors may result in elevated levels of and toxicity from doripenem(1) or meropenem.(2) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of doripenem states that concurrent use of organic anion transporter 3 (OAT3) inhibitors is not recommended.(1) The US manufacturer of meropenem states that concurrent use of OAT3 inhibitors is not recommended.(2) DISCUSSION: Probenecid has been shown to increase doripenem half-life (T1/2) and area-under-curve (AUC) by 53% and 75%, respectively.(1) In a study in six subjects, concurrent probenecid increased meropenem T1/2 by 33%.(3) Other studies have shown probenecid to increase the T1/2 of meropenem by 38% and the extent of meropenem systemic exposure by 58%.(2) OAT3 inhibitors linked to this monograph include: leflunomide, probenecid, teriflunomide, and vadadustat.(4)	ARAVA, AUBAGIO, LEFLUNICLO, LEFLUNOMIDE, PROBENECID, PROBENECID-COLCHICINE, TERIFLUNOMIDE, VAFSEO
Fecal Microbiota Spores/Antibiotics SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Fecal microbiota spores is a suspension of live bacterial spores, which may be compromised by concurrent use of antibiotics.(1) CLINICAL EFFECTS: Antibiotics may decrease the effectiveness of fecal microbiota spores.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Antibiotics should not be used concurrently with fecal microbiota spores. Antibacterial treatment should be completed for 2 to 4 days before initiating treatment with fecal microbiota spores.(1) DISCUSSION: Antibiotics may compromise the effectiveness of fecal microbiota spores.

Not known whether meropenem is distributed into milk. Use with caution.

No substantial differences in safety and efficacy relative to younger adults, but increased sensitivity cannot be ruled out. Substantially eliminated by kidneys; risk of toxicity may be greater in patients with impaired renal function. Select dosage with caution and assess renal function periodically since geriatric patients are more likely to have renal impairment.

No dosage adjustments except those related to renal function. (See Dosage in Renal and Hepatic Impairment under Dosage and Administration: Dosage.)
