Treatment Covid-19

Indications

Emergency use of Remdesivir for treatment of suspected or laboratory confirmed Corona Virus Disease 2019 (COVID-19). Severe disease is defined as patients with an oxygen saturation (Sp02) <94% on room air or requiring supplemental oxygen or requiring mechanical ventilation or requiring extracorporeal membrane oxygenation (ECMO). Specifically, Remdesivir is only authorized for hospitalized adult and pediatric patients for whom use of an intravenous agent is clinically appropriate.

Pharmacology

Remdesivir is a preparation of Remdesivir. It is an adenosine nucleotide prodrug that distributes into cells where it is metabolized to form the pharmacologically active nucleoside triphosphate metabolite. Metabolism of Remdesivir to Remdesivir Triphosphate has been demonstrated in multiple cell types. Remdesivir Triphosphate act as an analogue of adenosine triphosphate (ATP) and competes with the natural ATP substrate for incorporation into nascent RNA chains by the SARS-CoV-2 RNA-dependent RNA polymerase, which results in delayed chain termination during replication of the viral RNA. Remdesivir triphosphate is a weak inhibitor of mammalian DNA and RNA polymerase with low potential for mitochondrial toxicity.

Dosage

General Information-

  • Adult and pediatric patients (>28 days and old) must have an eGFR determined and full-term neonates (≥7 days to ≤28 days old) must have serum creatinine determined before dosing of Remdesivir.
  • Hepatic laboratory testing should be performed in all patients prior to starting Remdesivir and daily while receiving Remdesivir.
  • Remdesivir should be administered via intravenous infusion only. Do not administer as intramuscular injection.

Adult Patients-

  • The recommended dosage in adults requiring invasive mechanical ventilation and/or ECMO is a single loading dose of Remdesivir 200 mg on day 1 followed by once daily maintenance dose of Remdesivir 100 mg for 9 days.
  • The recommended dose in adults not requiring invasive mechanical ventilation and/or ECMO is a single dose of Remdesivir 200 mg on day 1 followed by once daily maintenance dose of Remdesivir 100 mg for 4 days. If a patient dose not demonstrate clinical improvement, treatment may be extended for up to 5 additional days (i.e. up to a total of 10 days)
  • Remdesivir is to be administered via intravenous infusion in a total volume of up to 250 ml 0.9% saline over 30 to 120 minutes.

Pediatric Patients-

  • The recommended pediatric dose for pediatric patients weighing between 3.5 kg <40 kg should be calculated using the mg/kg dose according to the patient’s weight.
  • For pediatric patients with body weight between 3.5 kg <40 kg use Remdesivir for injection 100 mg lyophilized powder only. Administer a body weight-based dosing regimen of one loading dose of Remdesivir 5 mg/kg IV (infused over 30 to 120 minutes) on day 1 followed by Remdesivir 2.5 mg/kg IV (infused over 30 to 120 minutes) once daily for 9 days (for pediatric patients requiring invasive mechanical ventilation and/or ECMO, days 2 through 5). If a patient dose not demonstrate clinical improvement, treatment may be extended for up to 5 additional days (i.e. up to a total of 10 days)
  • For pediatric patients with body weight ≥40 kg requiring invasive mechanical ventilation and/or ECMO, the adult dosage regimen of one loading dose of Remdesivir 200 mg IV (infused over 30 to 120 minutes) on day 1 followed by Remdesivir 100 mg IV (infused over 30 to 120 minutes) once daily for 9 days will be administered.
  • For pediatric patients with body weight ≥40 kg requiring invasive mechanical ventilation and/or ECMO, the adult dosage regimen of one loading dose of Remdesivir 200 mg IV (infused over 30 to 120 minutes) on day 1 followed by Remdesivir 100 mg IV (infused over 30 to 120 minutes) once daily for 4 days (days 2 through 5) will be administered. If a patient does not demonstrate clinical improvement, treatment may be extended for up to 5 additional days (i.e. up to a total of 10 days).

Administration

The prepared dilution should not be administered simultaneously with any other medication. The compatibility of Remdesivir injection with IV solutions and medications other than saline is not known. Please administered the diluted solution with the infusion rate described in the below table.

Side Effects

An adverse reaction associated with Remdesivir in clinical trials in healthy adult subjects was increased liver transaminases.

Pregnancy & Lactation

No adequate and well controlled studies of Remdesivir use in pregnant women have been conducted. Remdesivir should be used in pregnancy only if the potential benefit justifies the potential risk for the mother fetus. There is no information regarding the presence of Remdesivir in human milk, the effects on the breastfeed infants, or the effects on milk production. Because of the potential for viral transmission of SARS-CoV-2 negative infants and adverse reactions from the drug in breastfeeding infants, the development and health benefits of breastfeeding should be considered along with the mother’s clinical need for Remdesivir and any potential adverse effects on the breastfed child from Remdesivir or from the underlying maternal condition.

Precautions & Warnings

There are limited clinical data available for Remdesivir. Serious and unexpected adverse events may occur that have not been previously reported with Remdesivir use.

Reconstitution

Reconstitution instructions:

  • Aseptically reconstitute Remdesivir lyophilized powder by addition of 19 ml of sterile water for injection using a suitably sized syringe and needle per vial.
  • Discard the vial if a vacuum does not pull the sterile water for injection into the vial.
  • Immediately shake the vial for 30 seconds.
  • Allow the contents of the vial to settle for 2 to 3 minutes. A clear solution should result.
  • If the content of the vial is not completely dissolved, shake the vial again for 30 seconds and allow the contents to settle for 2 to 3 minutes. Repeat this procedure as necessary until the contents of the vial are completely dissolved.
  • Following reconstitution, each vial contains 100 mg/20 ml (5 mg/ml).
  • Parenteral drug products should be inspected virtually for particulate matter and and discoloration prior to administration, whenever solution and container permit.
