What is the best OTC muscle relaxer?
The major purpose of muscle relaxants is to treat the painful musculoskeletal conditions, muscle spasms associated with overexertion and help manage the spasticity of sever chronic diseases.

Broadly the term muscle relaxants can be subdivided into two major groups called as neuromuscular blockers and spasmolytic. The function of neuromuscular blockers is to block N1 receptors in the neuromuscular junction to prevent skeletal muscular contractions. These are mainly used during the time of surgeries and for procedures that require short-term flaccid paralysis such as intubation. The spasmolytic work centrally at the spinal cord or brain. These drugs when used along with physical therapy to treat muscle spasms associated with overexertion help manage the spasticity of sever chronic diseases in the best way possible and yield positive results.
Muscle relaxers mechanism of action
We need to review a cross section of the spinal cord in order to understand the mechanism of muscle relaxers such as Baclofen and Tizanidine.
A UMN or upper motor neuron is activated in the cerebral cortex causing voluntary contraction of muscle in the limbs. And the action potentials then travel down the spinal cord with lower motor neurons at the level of exit.
Diazepam and benzodiazepine used for muscle spasms bind to the BZD binding sites of GABA-A receptors situated on cell bodies of the lower motor neuron that increase the permeability of chlorine inside the cell. This action augments the action of GABA and hyperpolarizes the cell even more. This decreases the frequency of action potentials traveling through the element to the muscle.
Baclofen activates the GABA -A receptors in the postsynaptic membrane that causes an increase in the potassium conductance in the alamin which eventually causes hyperpolarization. Activation of GABA- B receptors that are present in the presynaptic membrane of the upper motor neuron leads to less release of calcium ions that eventually causes fewer action potentials travel down the LMN to reach the muscle.
Several muscle relaxers used for local muscle spasms are associated with overexertion or injuries. People facing car accidents or manual laborers are examples of individuals under the impact of these drugs which commonly are –
Adverse effects of Muscle Relaxers
Most muscle relaxers are CNS depressants and must not be mixed with alcohol and proper caution must be adopted while operating machinery or driving. Most muscle relaxers acting in the CNS have the following adverse effects in common –
- Muscle weakness
- Lightheadness or dizziness
