Muscle relaxants are a class of medications used to treat muscle spasms and spasticity. They work by interfering with the signals sent from the brain and spinal cord to the muscles, reducing muscle tension and allowing them to relax.
Types of Muscle Relaxants
There are three main types of muscle relaxants:
1. Direct-Acting Muscle Relaxants: These medications work directly on the muscle fibers themselves to prevent muscle contraction.
2. Centrally Acting Muscle Relaxants: These medications work on the central nervous system (CNS) to reduce muscle spasms.
3. Alpha-2 Adrenergic Agonists: These medications work on the spinal cord to decrease muscle spasms.
Common Muscle Relaxants and Their Uses
Here are some of the most common muscle relaxants and their uses:
Dantrolene: A direct-acting muscle relaxant used to treat muscle spasticity caused by spinal cord injuries, cerebral palsy, multiple sclerosis, and malignant hyperthermia.
Baclofen: A centrally acting muscle relaxant used to treat muscle spasticity caused by spinal cord injuries, cerebral palsy, and multiple sclerosis.
Tizanidine: An alpha-2 adrenergic agonist used to treat muscle spasticity caused by spinal cord injuries, cerebral palsy, and multiple sclerosis.
Side Effects of Muscle Relaxants
