Rimantadine Usage And Synthesis
  • DescriptionRimantadine (Brand name: Flumadine) is a kind of RNA synthesis inhibitor that used as an orally administrated antiviral drug in the prophylaxis and for the treatment of influenza. It is capable of shortening the duration and alleviated the symptoms of influenza. However, it is now not recommended for the treatment of influenza any longer due to the emergence of resistance problem since 2009. Its mechanism of action is not fully understood. It is indicated that it take effects through inhibiting the viral replication through possibly inhibiting the uncoating process of the virus. The virus M2 protein (an ion channel) seems to play an important role in the susceptibility of influenza A virus to the treatment of Rimantadine.

  • UsesRimantadine act by blocking the M2 ion channel which is required for uptake of protons into the interior of the virus to permit acid-promoted viral uncoating (decapsidation).
  • brand nameFlumadine (Forest).
  • General DescriptionResistant variants of influenza type A have been recoveredfrom rimantadine-treated patients.Resistance with inhibitory concentrations increased morethan 100-fold have been associated with single nucleotidechanges that lead to amino acid substitutions in the transmembranedomain of M2. rimantadineshare cross-susceptibility and resistance.
  • Pharmaceutical ApplicationsAn analog of amantadine, supplied as the hydrochloride for oral administration.
  • PharmacokineticsOral absorption: >90%
    Cmax 100 mg oral (every 12 h): 0.4–0.5 mg/L after 2–6 h
    Plasma half-life: c. 35 h
    Volume of distribution: Very large
    Plasma protein binding: c. 40%
    Absorption and distribution
    Single- and multiple-dose pharmacokinetic studies in elderly patients and young adults are remarkably similar. The steadystate concentration in nasal mucus develops by day 5 at a concentration approximately 1.5-fold higher than plasma.
    Metabolism
    In contrast to amantadine, rimantadine is extensively metabolized in the liver by hydroxylation and glucuronidation.
    Excretion
    Less than 20% is excreted unchanged in the urine and most of the breakdown products are excreted by this route. Thus, the plasma half-life is much less affected by renal dysfunction than that of amantadine.
  • Clinical UseProphylaxis and treatment of influenza A H1N1 infections Since prolonged administration is well tolerated by elderly patients, the drug is preferable to amantadine.
  • Clinical Userimantadine is used for the treatment of diseases caused by influenza A strains.
  • Side effectsRimantadine has significantly fewer side effects than amantadine at equivalent doses, perhaps because of differences in pharmacokinetics, since with equal doses the blood levels are considerably lower. CNS side effects are not significantly higher than placebo.
