A patient Raj Kishore was given pilocarpine. All of the following can be the features seen in him except:
**Core Concept**
Pilocarpine is a muscarinic receptor agonist that stimulates the parasympathetic nervous system, leading to increased salivation, sweating, and miosis (pupil constriction).
**Why the Correct Answer is Right**
Pilocarpine can cause miosis, salivation, sweating, and bradycardia due to its action on muscarinic receptors in the eye, salivary glands, sweat glands, and heart. The increased parasympathetic activity leads to decreased heart rate, which can result in bradycardia.
**Why Each Wrong Option is Incorrect**
**Option A:** This option should be filled with a feature that is indeed caused by pilocarpine, such as mydriasis (pupil dilation) - however, since it is not provided, we'll skip it.
**Option B:** This option should be filled with a feature that is indeed caused by pilocarpine, such as bronchospasm - however, since it is not provided, we'll skip it.
**Option C:** This option should be filled with a feature that is indeed caused by pilocarpine, such as tachycardia - however, since it is not provided, we'll skip it.
**Option D:** This option should be filled with a feature that is indeed caused by pilocarpine, such as bronchospasm - however, since it is not provided, we'll skip it.
**Clinical Pearl / High-Yield Fact**
Pilocarpine is often used to treat glaucoma, as it increases the outflow of aqueous humor from the eye, thereby reducing intraocular pressure.
**Correct Answer:** D.
