Question

Carvedilol is a mixture of how many enantiomers?

• A. \( \text{2} \)
• B. \( \text{4} \)
• C. \( \text{6} \)
• D. \( \text{8} \)

Hint:

Enantiomers can have distinct pharmacological effects, making stereochemistry an essential factor in drug development.

Answer 1

The Correct Option is A

Carvedilol is a non-selective beta-blocker with vasodilatory properties. It is a racemic mixture composed of two enantiomers: \( R \)-carvedilol and \( S \)-carvedilol. The \( S \)-enantiomer primarily contributes to beta-blocking activity, while both enantiomers exhibit alpha-blocking effects.
