What is the fundamental difference in receptor classification between Baclofen and Diazepam?
Answer
Baclofen is a GABA-B receptor agonist, while Diazepam modulates GABA-A receptors.
The most significant pharmacological divergence between these two agents lies in their target receptors within the GABA system. Diazepam is classified as a benzodiazepine that functions as a positive allosteric modulator of the GABA-A receptor. In contrast, Baclofen is structurally and functionally classified as a GABA-B receptor agonist. This means Baclofen selectively mimics the action of GABA at the GABA-B receptors, whereas diazepam enhances GABA's action at the GABA-A receptors. This separation between GABA-A and GABA-B targets is crucial because it dictates their differing primary medical applications and symptomatic profiles.
