What is the primary indication for muscle relaxants?

Muscle relaxants are primarily indicated for their ability to reduce muscle tension. They work by acting on the central nervous system or directly on skeletal muscles to alleviate conditions characterized by muscle spasm, spasticity, or excessive muscle contraction. This reduction in muscle tension can help alleviate pain and improve mobility and function in patients suffering from various musculoskeletal conditions, such as acute back pain, fibromyalgia, and neurological disorders.

While some other medications and treatments may target pain relief, airway management, or the treatment of inflammatory arthritis, they do not primarily focus on reducing muscle tension as their main function.
