Analysis Of Amantadine Formulations For Off And Dyskinesia In Parkinson Disease

W. Oertel, R. Pahwa, R. Hauser, M. Sale, G. Went

Category:Parkinsons Disease: Pharmacology and Therapy

Objective: Evaluate the effects of amantadine formulations on the treatment of OFF and dyskinesia in Parkinsons patients.

Background: There are currently three formulations of amantadine available in the US: immediate release tablets, immediate release/extended release tablets and delayed release/extended release capsules. The DR/ER formulation is the only FDA-approved and effective medication for Parkinsons motor complications, decreasing both OFF time and dyskinesia compared to placebo. Clinical trials for other AMT IR and IR/ER formulations have demonstrated effects on dyskinesia in patients with Parkinsons disease, however, no published trials have compared efficacy amongst all three.

Method: An indirect treatment comparison was performed. The literature studies of AMT IR in PD patients with OFF and dyskinesia were utilized, along with data from pivotal trials of AMT DR/ER and AMT IR/ER. For each trial, where available, the mean treatment differences in diary states of OFF and ON with troublesome dyskinesia were obtained directly or calculated from the active and placebo arms, relative to baseline. The treatment effect magnitude was computed for each treatment option and reported as percentage. For AMT IR/ER, data for the two doses used in the phase 3 trials were pooled to increase the sample size using statistically weighted averages.

Parkinson disease is a neurological disorder where patients have a lack of dopaminergic neurons in the substantia nigra. The affected population is estimated to extend toward 10 million worldwide.2 Drug-induced extrapyramidal reactions, mainly caused by antipsychotics, has led to many problematic symptoms such as dystonia, pseudo-parkinsonism, akathisia, and tardive dyskinesia. Anticholinergics, such as amantadine have been used to treat extrapyramidal symptoms caused by antipsychotics for many years now.3

Chemistry Mechanism Of Action Spectrum And Resistance

Amantadine and rimantadine are symmetric tricyclic amines with cagelike structures that are closely related structurally to one another. Amantadine was the first antiviral agent to be licensed for systemic use in the U.S. The activity of amantadine and rimantadine is limited to influenza A viruses. Rimantadine is 4- to 10-fold more active than amantadine.268 The target of the inhibitory action for both amantadine and rimantadine is the influenza A virus M2 protein. Resistance to amantadine and rimantadine results from a point mutation in the RNA sequence encoding for the M2 protein transmembrane domain.269 Resistance typically appears in the treated subject and his or her close contacts within 2 to 3 days of the initiation of therapy as many as one-third of treated adults and children shed resistant strains of influenza by the fifth day of treatment.270
