causes of drooling
Cerebral palsy is one example of a condition in which oral neuromuscular control may be impaired, resulting in drooling. Drooling is common in infants because of immature muscular control. Medically, drooling is referred to as ptyalism, and an excess of saliva is known as sialorrhea.
A double-blind trial illustrated a 50% decrease in drooling with the administration of benztropine in adults. However, the results varied significantly in the study that included a pediatric population. Glycopyrrolate was also shown to decrease drooling in 95% of patients.
