Clinical Applications and Adverse Effects
Start with the big picture
Clinical use depends on matching a drug’s action and safety profile to the problem being treated. Baclofen and tizanidine are used for spasticity, while dantrolene has roles in malignant hyperthermia, neuroleptic malignant syndrome, and chronic spasticity. Diazepam and several other centrally acting agents are used for acute muscle spasm, with risks such as sedation and CNS depression. Botulinum toxin is used for focal dystonia and spasticity, and neuromuscular blockers support intubation, surgical relaxation, or prolonged ventilation. Important adverse effects span hypotension, hepatotoxicity, muscle weakness, respiratory depression, and risks specific to depolarizing or nondepolarizing blockers. The deeper lesson organizes these agents by mechanism and clinical role, then highlights adverse-effect patterns and clinical distinctions.
What you'll learn
- Match baclofen, tizanidine, and dantrolene with their stated clinical applications.

- Identify important adverse effects associated with centrally acting spasmolytics.
- Compare the clinical roles and risks of depolarizing and nondepolarizing blockers.
- Describe the clinical uses and key adverse effects of botulinum toxin.
