Baclofen Pharmacology

Baclofen is primarily used for its ability to help relieve muscle spasms. I discuss baclofen pharmacology on this podcast episode. Baclofen should not be abruptly discontinued as it can cause a significant withdrawal reaction whose symptoms may include fever, spasticity, rhabdomyolysis, and death. While baclofen generally avoids any issues with CYP enzyme interactions, it is eliminated by the kidney. Renal function changes can alter drug concentrations. Sedation, confusion, dizziness, hypotension, and GI upset are some of the more common adverse effects of baclofen.
