A Muscle Relaxant is a drug which affects skeletal muscle value derived and decreases the muscle tone.

It may be used to alleviate symptoms such as muscle spasm and vexation, and hyperreflexia. The term 'muscle relaxant' is used to refer to two major therapeutic groups: neuromuscular blockers and spasmolytics.

Neuromuscular blockers act through interfering by transmission at the neuromuscular end dish and have no CNS activity.

They are often used during surgical procedures and in emphatic care and emergency medicine to cause paralysis.

Spasmolytics, also known as 'centrally-acting' muscle relaxants, are used to alleviate musculoskeletal pain and spasms and to reduce spasticity in a variety of neurological conditions.

While the couple neuromuscular blockers and spasmolytics are ofttimes grouped together as muscle relaxants, the term is commonly used to apply to spasmolytics only.
