PRIMAXIN?I.V.(Imipenem and Cilastatin for Injection)78821316

Pseudomonas aeruginosa, Serratia species, Peptococcus species, Peptostreptococcus species,

Bacteroides species including B. fragilis, Fusobacterium species*

(8)   Endocarditis. Staphylococcus aureus (penicillinase-producing strains)

(9)   Polymicrobic infections. ZIMILAST I.V. is indicated for polymicorbic infections including those in which S.pneumoniae (pneumonia,septicemia), S.pyogenes (skin and skin structure), or nonpenicillinase-producing S. aureus is one of the causative organisms. However,monobacterial infections due to these organisms are usually treated with narrower spectrum antibiotics, such as penicillin G.

ZIMILASTI.V. is not indicated in patients with meningitis because safety and efficacy have not been established.

 

CONTRAINDICATIONS

ZIMILASTI.V. is contraindicated in patients who have shown hypersensitivity to any component of this product.

 

Dosage and administration;

Adults

The dosage recommendations for ZIMILAST I.V. represent the quantity of imipenem to be administered.

An equivalent amount of cilastatin is also present in the solution. Each 125mg, 250mg, or 500mg dose should be given by intravenous administration over 20 to 30 minutes. Each 750mg or 1000mg dose should be infused over 40 to 60minutes. In patients who develop nausea during the infusion, the rate of infusionmay be slowed.

The total daily dosage for ZIMILAST I.V. should be based on the type or severity of infection and given in equally divided doses based on consideration of degree of susceptibility of the pathogen(s), renalfunction, and body weight. Adult patients with impaired renal function, as judged by creatinine clearance=70ml/min/1.73m2, require adjustment of dosage.

 

Type or Severity of Infection Fully susceptibleOrganisms includingGram positive and Gram negative aerobes and anaerobes Moderately susceptible organisms, primarily some strains of P.Aeruginosa
Mild 250mg q 6h(Total Daily Dose=1.0g) 500mg q 6h(Total Daily Dose=2.0g)
Moderate 500mg q 8h(Total Daily Dose=1.5g)Or500mg q 6h(Total Daily Dose=2.0g) 500mg q 6h(Total Daily Dose=2.0g)Or1g q 8h(Total Daily Dose=3.0g)
Severe Life threatening Only 500mg q 6 h(Total Daily Dose=2.0g) 1g q 8 h(Total Daily Dose=3.0g)Or1g q 6 h(Total Daily Dose=4.0g)
Uncomplicated urinary tract Infection 250mg q 6 h(Total Daily Dose=1.0g) 250mg q 6 h(Total Daily Dose=1.0g)
Complicated urinary tract Infection 500mg q 6 h(Total Daily Dose=2.0g) 500mg q 6 h(Total Daily Dose=2.0g)
   
   

Due to the high antimicrobial activity of ZIMILASTI.V., it is recommended that the maximum total daily dosage not exceed 50mg/kg/day or 4.0 g/day, whichever is lower.

 

Paediatric patients

For pediatric patients = 3 months of age, the recommended dose for non-CNS infections is 15-25mg/kg every sixed hours. Based on studies in adults, the maximum daily dose for treatment of infections with fully susceptible organisms is 2.0g per day, and of infections with moderately suscetpibleorganisms(primarily some strains of P. aeruginosa) is 4.0g/day. Higher doses (up to 90mg/kg/day in older children)have been used in patients with cystic fibrosis.

For pediatric patient= 3 months of age (weighing=1500 gms), the following dosage schedule is recommended for non.CNS infections: <1 wk of age: 25mg/kg every 12 hrs, 1-4 wks of age: 25mg/kg every 8 hrs, 4wks-3mos. of age: 25mg/kg every 6 hrs.

Doses less than or equal to 500mg should be given by intravenous infusion over 15 to 30 minutes.

Doses greater than 500 mg should be given by intravenous infusion over 40 to 60 minutes.

ZIMILAST I.V. is not recommended in pediatric patients with CNS infections because of the risk of seizures. is not recommended in pediatric patients <30 kg with impaired renal function.,

 

Drug Interactions

Generalized seizures have been reported in patients who received ganciclovir and ZIMILAST.

It is not recommended that probenecid be given with ZIMILAST: ZIMILAST should not be mixed with or physically added to other antibiotics. However, ZIMILAST may be administered concomitantly with other antibiotics, such as aminoglycosides.
