**Question:** Extra pyramidal syndrome like side effects are seen in:

A. Antipsychotics
B. Antidepressants
C. Anticonvulsants
D. Beta-blockers

**Core Concept:** Extra pyramidal syndrome (EPS) is a group of movement disorders caused by the use of certain medications. It is characterized by symptoms such as tremors, muscle rigidity, and impaired voluntary movement. The most common cause of EPS is the use of antipsychotic drugs, which primarily affect dopamine neurotransmission.

**Why the Correct Answer is Right:** Extra pyramidal syndrome like side effects are primarily seen in the use of antipsychotics. This is because antipsychotic drugs, such as those in the thioxanthene and benzothiazepine classes, act as dopamine antagonists. Dopamine is a neurotransmitter involved in motor control, and blocking its activity can lead to EPS.

**Why Each Wrong Option is Incorrect:**

A. Antipsychotics: While the question asks for side effects, these drugs are the cause of EPS, not the result.
B. Antidepressants: Most antidepressants do not cause EPS due to their selective actions on serotonin and norepinephrine neurotransmitters.
C. Anticonvulsants: While anticonvulsants can cause extrapyramidal symptoms, it is less common compared to antipsychotics.
D. Beta-blockers: These drugs primarily affect the cardiovascular system and are not associated with EPS.

**Clinical Pearl:** It is essential for medical professionals to be aware of the potential side effects of medications they prescribe, including EPS in the case of antipsychotics. Monitoring patients on these drugs for motor symptoms and adjusting the dosage or medication choice accordingly can help minimize the risk of EPS and improve patient care.
