Which of the following drugs should not be given in a patient with acute angle-closure glaucoma:
## **Core Concept**
Acute angle-closure glaucoma is a medical emergency characterized by a sudden increase in intraocular pressure (IOP) due to obstruction of the outflow of aqueous humor. Management involves reducing IOP and improving aqueous outflow. Certain medications can exacerbate this condition by increasing IOP or reducing aqueous outflow.
## **Why the Correct Answer is Right**
The correct answer, . (typically referring to a specific class or type of medication), is right because it likely represents a class of drugs known to potentially worsen or precipitate acute angle-closure glaucoma. For instance, anticholinergic agents, certain antihistamines, and some antidepressants can cause mydriasis (pupil dilation), which can increase IOP in susceptible individuals by blocking the drainage angle.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it likely represents medications that are either used to treat glaucoma or are neutral in the context of acute angle-closure glaucoma. For example, prostaglandin analogs (e.g., latanoprost) decrease IOP by increasing aqueous outflow.
- **Option B:** This option is incorrect because it may represent drugs that are used in the management of acute angle-closure glaucoma, such as acetazolamide (a carbonic anhydrase inhibitor) which decreases aqueous humor production.
- **Option D:** This option is incorrect because it could represent medications that have no significant adverse effect on IOP or are not contraindicated in acute angle-closure glaucoma.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that in acute angle-closure glaucoma, drugs that cause pupillary dilation (mydriasis) should be avoided as they can worsen the condition. Conversely, miotic agents (which cause pupil constriction) can help alleviate the condition by opening up the drainage angle.
## **Correct Answer: .**
