The potentiation of the ami akinetic effect after L-Dopa treatment by an inhibitor of monoamine oxidase (MAO) “B”, Deprenil, has been demonstrated in parkinsonian patients with or without previous L-Dopa therapy. Application of the drug has been performed orally, intravenously and intramuscularly. Excellent kinetic effects resulted when combined with Madopar. The combined treatment with L-Dopa was highly effective when applicated i.v. or i.m.
Deprenil is an inhibitor of MAO-B and is characterized by less frequent side effects. These are predominantly involuntary movements and confusion, which can be eliminated by lowering the dosage of Deprenil.
A daily rhythm of MAO could be demonstrated in several areas of human brains as well in a control group as in parkinsonian patients with or without L-Dopa therapy. Maximal activity of MAO occurs between noon and 6 p.m.
The clinical and biochemical data are discussed regarding the off-phenomenons as Deprenil is an excellent drug for preventing these.
