What condition may exacerbate if a patient is prescribed anticholinergic medications?

Anticholinergic medications can exacerbate glaucoma, particularly in patients with narrow-angle glaucoma. These medications work by blocking the action of acetylcholine, which can lead to increased intraocular pressure. In narrow-angle glaucoma, there is already a predisposition to elevated pressure in the eye, and anticholinergic drugs can worsen this condition by causing pupil dilation (mydriasis) and potentially leading to an acute glaucoma attack.

In contrast, asthma may be managed with anticholinergic medications that can help to widen the air passages in the lungs, which may offer relief for patients with bronchospasm but is not exacerbated. Hypotension and heart failure are also not typically exacerbated by anticholinergic effects. Therefore, the focus should remain on understanding how anticholinergic medications specifically impact intraocular pressure and the mechanisms that lead to worsening conditions such as glaucoma.
