movements and troublesome restlessness. Agitane also
reduces muscular stiffness and saliva production.
Agitane is used in the management of Parkinson’s disease
or Parkinsonism caused by encephalitis or hardening of the
arteries. It is also used to control certain types of disorder
such as muscular rigidity, stiffness, tremor (fine shaking of
the hands), spasm which may be caused by certain drugs
acting on the central nervous system of which the
phenothiazine drugs (used to treat mental disorders,
nausea and vomiting) are examples.
