The FDA has approved adjunctive treatment with Dartisla ODT (Edenbridge), a new orally disintegrating tablet (ODT) formulation of the anticholinergic drug glycopyrrolate, to reduce symptoms of a peptic ulcer. Glycopyrrolate oral tablets (Robinul, Robinul Forte, and generics) were approved for the same indication in 1961.

Glycopyrrolate (Robinul, and others), a synthetic muscarinic receptor antagonist, has been used off-label for many years for treatment of excessive drooling in patients with Parkinson’s disease, in patients taking clozapine for schizophrenia, and in developmentally disabled children.1-3 It has now been approved by the FDA as Cuvposa (Shionogi) for use specifically in children 3-16 years old with severe chronic drooling due to a neurologic condition, such as cerebral palsy. It is being marketed as an oral solution, which will permit more precise weight-based dosing than was possible with the oral tablets used in the past. As with other anticholinergic drugs, dry mouth, constipation, flushing and nasal congestion can occur. Since glycopyrrolate decreases secretion not only of saliva, but also of sweat, overheating due to high ambient temperatures or excessive exercise could be dangerous for patients who take it.
