Introduction

Aciclovir is the brand name of Aciclovir, a synthetic purine nucleoside with inhibitory activity against herpes simplex virus(HSV-1 & HSV-2) and varicella-zoster virus (VZV). The activity of Aciclovir is highly selective due to its affinity for the enzyme thymidine kinase encoded by HSV and VZV. This viral enzyme converts Aciclovir into Aciclovir monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate and finally triphosphate by a number of cellular enzymes. In vitro, Aciclovir triphosphate stops replication of herpes viral DNA. This is accomplished in 3 ways: 1) Competitive inhibition of viral DNA polymerase, 2) Incorporation into and termination of the growing viral DNA chain and 3) Inactivation of the viral DNA polymerase.

Therapeutic Class

Dose adjustment of Tablet for patients with acute or chronic renal impairment, based on Creatinine Clearance, Cr Cl (mL/min/1.73 m2):

For Cr Cl= > 25 : 800 mg 4 hourly 5 times daily

For Cr Cl = 10 to 25 : 200 mg 4 hourly 5 times daily or 400 mg 12 hourly or 800 mg 8 hourly

For Cr Cl = 0 to 10 : 200 mg 12 hourly or 400 mg 12 hourly or 800 mg 12 hourly

Dose adjustment of IV for patients with acute or chronic renal impairment, based on Creatinine Clearance, Cr Cl (mL/min/1.73 m2):

For Cr Cl = > 50 : 100% of recommended dose, 8 hourly

For Cr Cl = 25 to 50 : 100% of recommended dose, 12 hourly

For Cr Cl = 10 to 25 : 100% of recommended dose, 24 hourly

For Cr Cl = 0 to 10 : 50% of recommended dose, 24 hourly

Caution: Rapid or bolus intravenous injection must be avoided. Intramuscular or subcutaneous injection must be avoided.

Reconstitution procedure of IV infusion

Vial containing 250 mg Aciclovir will be reconstituted with 50 ml infusion solution and vial containing 500 mg Aciclovir will be reconstituted with 100 ml infusion solution. Besides, Vial containing 1 gm Aciclovir will be reconstituted with 250 ml infusion solution. 10 ml of the infusion solution will be added to the vial containing 250 mg, 500 mg and 1 gm Aciclovir.

Precaution

Aciclovir should be administered with caution in patient with renal impairment and doses should be adjusted according to creatinine clearance.

Interaction

Coadministration of probenecid with acyclovir has been shown to increase the mean acyclovir half-life and the area under the concentration-time curve. Urinary excretion and renal clearance were correspondingly reduced.

Acerux IV Infusion Uses During Pregnancy

Pregnancy category B. There are no adequate and well-controlled studies in pregnant women. Acyclovir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. 

Use in nursing mothers: Acyclovir should be administered to a nursing mother with caution and only when indicated. Geriatric Use: No overall differences in safety are observed between older and younger subjects.

Management: Consider use of haemodialysis until renal function is restored.

Contraindication

Acyclovir IV Injection is contraindicated in patients known to be hypersensitive to Acyclovir or Valacyclovir.

Uses Direction

It is recommended that Acyclovir IV Injection for Intravenous Infusion should be administered for five to seven days in the treatment of most infections and for at least ten days in the treatment of Herpes simplex encephalitis.

Each 250 mg vial of Acyclovir IV Injection should be reconstituted by the addition of 10 ml of either Water for Injection or Sodium Chloride Intravenous Infusion (0.9% w/v). This provides a solution containing 25 mg Acyclovir per ml.

Each 500 mg vial of Acyclovir IV Injection should be reconstituted by the addition of 10 ml of either Water for Injection or Sodium Chloride Intravenous Infusion (0.9% w/v). This provides a solution containing 50 mg Acyclovir per ml.

Storage Condition

Store at 15°C to 25°C. Protected from light and moisture. Keep the medicine out of the reach of children.

Special Warning

The dose of Acyclovir IV injection in children aged 1-12 years should be calculated on the basis of body surface area. Children in this age group with Herpes simplex infections (except Herpes simplex encephalitis) or Varicella zoster infections should be given Acyclovir Infusion in doses of 250 mg per square metre of body surface area (equivalent to 5 mg/kg in adults). Immunocompromised children in this age group with Varicella zoster virus infection or with Herpes simplex encephalitis should be given Acyclovir IV Infusion in doses of 500 mg per square metre of body surface area (equivalent to 10 mg/kg in adults). Children with impaired renal function require an appropriately modified dose, according to the degree of impairment.

Interactions with other Medicine

Probenecid reduces Aciclovir excretion and so increases plasma concentration and risk of toxicity.
