Amantadine sulfate

white fine crystalline powder

Amantadine sulfate is an alkylammonium sulfate salt obtained by combining amantadine and sulfuric acid in a 2:1 ratio. Used as an antiviral and antiparkinson drug. It has a role as an antiparkinson drug, an antiviral drug, a dopaminergic agent, a NMDA receptor antagonist and a non-narcotic analgesic. It contains an adamantan-1-aminium.|Amantadine Sulfate is the sulfate salt of amantadine, a synthetic tricyclic amine with antiviral, antiparkinsonian, and antihyperalgesic activities. Amantadine appears to exert its antiviral effect against the influenza A virus by interfering with the function of the transmembrane domain of the viral M2 protein, thereby preventing the release of infectious viral nucleic acids into host cells; furthermore, this agent prevents virus assembly during virus replication. Amantadine exerts its antiparkinsonian effects by stimulating the release of dopamine from striatal dopaminergic nerve terminals and inhibiting its pre-synaptic reuptake. This agent may also exert some anticholinergic effect through inhibition of N-methyl-D-aspartic acid (NMDA) receptor-mediated stimulation of acetylcholine, resulting in antihyperalgesia.|An antiviral that is used in the prophylactic or symptomatic treatment of influenza A. It is also used as an antiparkinsonian agent, to treat extrapyramidal reactions, and for postherpetic neuralgia. The mechanisms of its effects in movement disorders are not well understood but probably reflect an increase in synthesis and release of dopamine, with perhaps some inhibition of dopamine uptake.
