Trihexyphenidyl is used for the symptomatic treatment of Parkinson’s disease in monotherapy or in combination. It is active in postencephalitic, arteriosclerotic and idiopathic forms.

It reduces the frequency and duration of oculogyric crises as well as dyskinetic movements and spastic contractions.

To increase therapeutic activity, trihexyphenidyl is often administered concomitantly with levodopa, other antimuscarinic or antihistamine agents. Combination therapy with dopamine agonists such as cabergoline is also possible. This is often called a “multidimensional approach”. It has also been prescribed for essential tremors and akathisia
