Myospas ET 4 is a combination medicine containing Etoricoxib (60mg) + Thiocolchicoside (4mg) which provides relief to patients experiencing muscular pain. It relieves muscle spasms and improves movement of muscles. Etoricoxib in Myospas is a medicine belonging to the Nonsteroidal anti-inflammatory drug (NSAD) group helpful for relieving moderate pain and inflammation. Etoricoxib works by blocking the effect of a natural chemical called cyclo-oxygenase-2 (COX-2) enzyme which causes inflammation and pain. Myospas ET4 also contains Thiocolchicoside which is a muscle relaxant with anti-inflammatory effects used for relieving muscular pain. This combination is also used for rheumatological and orthopaedic pain and pain caused due to trauma.

Your doctor has prescribed Myospas ET4 as you may be suffering from Muscle pain, muscle cramps, low back pain, sprains and strains.


Lower back pain is due to conditions affecting the spinal cord and nerves, ligaments around the spine and discs, discs between the vertebrae, muscles of the low back, internal organs of the pelvis and abdomen and the skin covering the lumbar area. It can also be caused due to narrowing of the space around the spinal cord which can put pressure on the spinal nerves. Fibromyalgia (widespread muscle aches and tenderness) too causes low back pain.

Massage may relieve chronic low back pain in combination with exercise and stretching. For severe pain or chronic pain, doctors may prescribe medication or injections to the back together with physiotherapy.


Muscle cramp or muscle spasm is an involuntary contraction of a muscle. Muscle spasms occur suddenly, usually resolve quickly, and are often painful. Muscle cramps happen due to muscle fatigue, dehydration and depletion of electrolytes. It also occurs if the muscle has been previously injured or strained, overstretched or if it has been held in the same position for a prolonged period of time. The muscle cell may run out of energy and fluid leading to a forceful contraction. Muscle spasms occur suddenly, are usually short-lived and often painful.


The initial treatment is to gently stretch the muscle.  For treating muscles that have been damaged or strained, medications may be required for pain relief like anti-inflammatories, narcotics and muscle relaxants.
