## Abstract Drooling is a frequent symptom in Parkinson's disease (PD), occurring in almost 75% of all patients. Although it is now well known that drooling in PD is the result of swallowing difficulties rather than excessive saliva production, few treatments have been developed to reduce it. Clini

β¦ Synopsis
To investigate the safety and efficacy of botulinum toxin type A (BoNTX) treatment to reduce sialorrhea in Parkinson's disease (PD), a double-blind, randomized, placebo-controlled study enrolled 32 PD patients complaining of excessive drooling. Patients received either 50 U Botox in each parotid gland or placebo without using ultrasound guidance. Subjects treated with BoNTX experienced a reduction in both drooling frequency and familial and social disability (TimexGroup effect: P<0.01), as well as in saliva production (Time x Group effect: P<0.0001). No adverse events were recorded. BoNTX injections are safe and effective treatment for the management of PD-related drooling.
