Remicov IV Infusion 5 mg/ml

Remicov IV Infusion 5 mg/ml Uses, Dosage, Side Effects, Food Interaction and all others data.

Remicov IV Infusion 5 mg/ml is a preparation of Remicov IV Infusion 5 mg/ml. It is an adenosine nucleotide prodrug that distributes into cells where it is metabolized to form the pharmacologically active nucleoside triphosphate metabolite. Metabolism of Remicov IV Infusion 5 mg/ml to Remicov IV Infusion 5 mg/ml Triphosphate has been demonstrated in multiple cell types. Remicov IV Infusion 5 mg/ml 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. Remicov IV Infusion 5 mg/ml triphosphate is a weak inhibitor of mammalian DNA and RNA polymerase with low potential for mitochondrial toxicity.

Remicov IV Infusion 5 mg/ml is a nucleoside analog used to inhibit the action of RNA polymerase. The duration of action is moderate, as it is given once daily. Due to much higher selectivity of mammalian DNA and RNA polymerases, including human mitochondrial RNA polymerase, for ATP over remdesivir triphosphate, remdesivir is not a significant inhibitor of these enzymes, which contributes to its overall tolerability and safety profile. Despite this, remdesivir carries risks for hypersensitivity reactions, including anaphylaxis and other infusion-related reactions, elevated transaminase levels, and potential decreased efficacy when combined with hydroxychloroquine or chloroquine.

Uses

Emergency use of Remicov IV Infusion 5 mg/ml 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, Remicov IV Infusion 5 mg/ml is only authorized for hospitalized adult and pediatric patients for whom use of an intravenous agent is clinically appropriate.

Remicov IV Infusion 5 mg/ml is also used to associated treatment for these conditions: Coronavirus Disease 2019 (COVID‑19)

How Remicov IV Infusion 5 mg/ml works

COVID-19 is caused by the positive-sense RNA virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Replication of the viral genome is a key step in the infectious cycle of RNA viruses, including those of the Filoviridae, Paramyxoviridae, Pneumoviridae, and Coronaviridae families, and is carried out by viral RNA-dependent RNA polymerase (RdRp) enzymes or enzyme complexes. For both SARS-CoV and SARS-CoV-2, the RdRp comprises nsp7, nsp8, and nsp12 subunits under physiological conditions, although functional RdRp complexes can be reassembled in vitro that incorporate only the nsp8 and nsp12 subunits, similar to the Middle East respiratory syndrome coronavirus (MERS-CoV).

Remicov IV Infusion 5 mg/ml is a phosphoramidite prodrug of a 1'-cyano-substituted adenosine nucleotide analogue that competes with ATP for incorporation into newly synthesized viral RNA by the corresponding RdRp complex. Remicov IV Infusion 5 mg/ml enters cells before being cleaved to its monophosphate form through the action of either carboxylesterase 1 or cathepsin A; it is subsequently phosphorylated by undescribed kinases to yield its active triphosphate form remdesivir triphosphate (RDV-TP or GS-443902). RDV-TP is efficiently incorporated by the SARS-CoV-2 RdRp complex, with a 3.65-fold selectivity for RDV-TP over endogenous ATP. Unlike some nucleoside analogues, remdesivir provides a free 3'-hydroxyl group that allows for continued chain elongation. However, modelling and in vitro experiments suggest that at i + 4 (corresponding to the position for the incorporation of the fourth nucleotide following RDV-TP incorporation), the 1'-cyano group of remdesivir sterically clashes with Ser-861 of the RdRp, preventing further enzyme translocation and terminating replication at position i + 3. This mechanism was essentially identical between SARS-CoV, SARS-CoV-2, and MERS-CoV, and genomic comparisons reveal that Ser-861 is conserved across alpha-, beta-, and deltacoronaviruses, suggesting remdesivir may possess broad antiviral activity.

Considerations for the use of nucleotide analogues like remdesivir include the possible accumulation of resistance mutations. Excision of analogues through the 3'-5' exonuclease (ExoN) activity of replication complexes, mediated in SARS-CoV by the nsp14 subunit, is of possible concern. Murine hepatitis viruses (MHVs) engineered to lack ExoN activity are approximately 4-fold more susceptible to remdesivir, supporting the proposed mechanism of action. However, the relatively mild benefit of ExoN activity to remdesivir resistance is proposed to involve its delayed chain termination mechanism, whereby additional endogenous nucleotides are incorporated following RDV-TP. In addition, serial passage of MHV in increasing concentrations of the remdesivir parent molecule GS-441524 led to the development of resistance mutations F476L and V553L, which maintain activity when transferred to SARS-CoV. However, these mutant viruses are less fit than wild-type in both competition assays and in vivo in the absence of selective pressure. To date, no clinical data on SARS-CoV-2 resistance to remdesivir have been described.

Remicov IV Infusion 5 mg/ml Alcohol interaction

[Moderate] GENERALLY AVOID:

Concomitant use of remdesivir with other agents that are known to induce hepatotoxicity may theoretically increase the risk of liver injury.

Data from investigational use and clinical studies suggest that remdesivir may be associated with hepatotoxic effects.

Transient treatment-emergent Grade 1 or Grade 2 elevations in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were observed during multiple-dose Phase 1 studies in healthy volunteers.

Some ALT and AST elevations were associated with graded PT elevations, but there were no graded changes in international normalized ratio (INR).

Laboratory results for these subjects indicated no systemic sign of drug reaction.

Liver transaminase elevations, including grade 3 or higher, were also observed in some participants during compassionate or investigational use of remdesivir and clinical studies for the treatment of COVID-19.

The mechanism of potential hepatotoxicity is unknown and the contribution of remdesivir is difficult to determine, as transaminase elevations have also been reported as a component of COVID-19, including in patients receiving placebo in clinical trials of remdesivir.

Until more information is available, concomitant use of remdesivir with known hepatotoxic drugs should be avoided when possible.

Liver function should be evaluated prior to starting remdesivir and monitored during treatment as clinically appropriate.

Remicov IV Infusion 5 mg/ml should not be initiated in patients with ALT greater than or equal to 5 times the upper limit of normal (ULN) at baseline.

Likewise, remdesivir should be discontinued immediately if ALT increases to 5 times ULN or greater during treatment (may be restarted when ALT falls below 5 times ULN), or if ALT elevation is accompanied by signs or symptoms of liver inflammation or increasing conjugated bilirubin, alkaline phosphatase, or INR.
