Parkinson's Disease - Medications

Drooling. In search of a simple solution for the problem of drooling, scientists have reported that injections of very small amounts of botulinum toxin A effectively reduce saliva production and drooling. In such small amounts the toxin is safe.

Constipation. Cisapride is being investigated for relieving constipation.

Voice Loss. A relatively simple procedure using collagen injections in the neck appears to be a safe and effective method of improving the voice and speech disorders caused by PD. The procedure augments the collagen in the vocal fold and works best in patients who can still initiate speech. A 2001 study reported improvements that lasted from two to seven months in 61% of patients.

Impotence. Sildenafil (Viagra) is proving to be very helpful for men who suffer from impotence from Parkinson's disease. However, the agent may worsen orthostatic hypotension, which may be a side effect of some of the PD medications.
