Amantadine is a tricyclic amine with antiviral, antiparkinsonian, and anti-hyperalgesia activities. This is used as an active component that 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. It is for the prevention of the release of infectious viral nucleic acids into host cells. It also prevents virus assembly during virus replication. It exerts its antiparkinsonian effects by stimulating the release of dopamine from striatal dopaminergic nerve terminals and inhibiting its pre-synaptic reuptake. It may also exert some anticholinergic effect through inhibition of N-methyl-D-aspartic acid receptor-mediated stimulation of acetylcholine, resulting in anti-hyperalgesia.
