First seen Apr 23, 2026 · Last updated Apr 23, 2026
Summary
This study tested whether injections of MYOBLOC (a botulinum toxin) into the saliva glands can safely reduce drooling in people with Parkinson's disease. Fifty-four participants received either the drug or a placebo, and researchers measured changes in drooling frequency and severity over 12 weeks. The goal was to find a tolerable dose that eases this bothersome symptom.
