Ipratropium bromide is absolutely contraindicated in
**Core Concept**
Ipratropium bromide is an anticholinergic medication used primarily in the management of chronic obstructive pulmonary disease (COPD) and asthma. As an anticholinergic agent, it acts by inhibiting the action of acetylcholine at muscarinic receptors in the lungs, thereby inducing bronchodilation.
**Why the Correct Answer is Right**
The correct answer is **Option A:** (to be filled in). Ipratropium bromide is contraindicated in patients with narrow-angle glaucoma because it can cause an increase in intraocular pressure. This is due to its anticholinergic effects, which can lead to decreased outflow of aqueous humor from the eye.
**Why Each Wrong Option is Incorrect**
* **Option B:** While ipratropium bromide can cause dry mouth and other anticholinergic side effects, it is not contraindicated in patients with angle-closure glaucoma without a narrow angle.
* **Option C:** Ipratropium bromide is not contraindicated in patients with urinary retention due to benign prostatic hyperplasia. In fact, it may be used cautiously in these patients to help manage bronchospasm.
**Clinical Pearl / High-Yield Fact**
Be aware of the potential for increased intraocular pressure with anticholinergic medications like ipratropium bromide, especially in patients with narrow-angle glaucoma.
**Correct Answer:** A. Narrow-angle glaucoma
