Which two medications are contraindicated in patients with narrow-angle glaucoma?

The choice specifying tricyclic antidepressants, particularly Amitriptyline and Nortriptyline, is correct because these medications have anticholinergic properties, which can lead to increased intraocular pressure in patients with narrow-angle glaucoma. This occurs due to the potential for these medications to cause pupil dilation, further narrowing the angle between the iris and cornea, which can exacerbate or trigger an acute glaucoma attack.

Tricyclic antidepressants are known to inhibit the action of acetylcholine, which can lead to several side effects, including blurred vision, dry mouth, constipation, and urinary retention—factors that can complicate the condition of patients with glaucoma. Consequently, the use of these medications in individuals with narrow-angle glaucoma poses a significant risk, making them contraindicated.

In contrast, while the other options may involve medications that have various side effects, they do not prominently feature the specific mechanism that poses a danger for narrow-angle glaucoma patients. This understanding of how certain medications can interact with the anatomical considerations of glaucoma is crucial for safe prescribing practices.
