Which drug is associated with decreased tear production due to anti-cholinergic effects?

Explanation:
Anticholinergic activity lowers tear production by blocking parasympathetic stimulation to the lacrimal glands, reducing lacrimal secretion and thinning the tear film. Isotretinoin is well known for causing ocular surface dryness and reduced tear production, likely through effects on the lacrimal and meibomian glands and goblet cells, leading to a thinner, less stable tear film. This is why isotretinoin is the drug most associated with decreased tear production in this context.
