What is a muscle relaxant?
muscle relaxants are drugs or other substances used to reduce muscle tone, also called tone or residual muscle tension or to induce temporary immobility. Muscle tol is a continuous partial contraction of muscles that keeps the muscles in a constant state of readiness for action. Muscle relaxants are used to treat muscle cramps and symptoms of disorders affecting muscle tone and to induce paralysis in the patient during medical procedures. The muscle relaxant can be placed in one of the two wide categories, spasmolytics and neuromuscular blocking drugs, although this term is often used specifically to the first. These drugs are often referred to as centrally acting muscle relaxants, which means that they work by affecting cells in the central nervous system. This is not entirely accurate because it has been found that some muscle relaxants actually do not create their effects in the central nervous system, but the term centrally acting muscle relaxant is still often afterIt uses as a blanket for all spasmolytic drugs.
spasms are sudden, involuntary contractions in skeletal muscles. Many convulsions are commonplace and smaller, such as cramps from intense exercise, but in more serious cases spams can cause severe pain and significantly disturbed mobility. Spasticity is a condition in which human skeletal muscles are in a constant state of increased tension or hypertonia. This worsens flexibility and movement by making it difficult to relax and stretch the muscles and over time this constant tension can affect bone alignment near the affected muscles. This can cause problems such as impaired mobility, reduced dexterity or unusual walking and, in some serious cases, can lead to overall paralysis.
Spasmolytics works either inventive inhibition or reduce excitation in motor neurons, which inhibits the creation of electric discharges that send signals fromcells into the cell. This reduces spasticity and convulsions by causing muscles to receive fewer signals that tell them to download. Commonly used spasmolytic drugs include diamepis (C 16 H 13 MCLN 2 O), Dantrolene (C 10 Cln 3 o 3 ).
Spasmolytic drugs are often used to treat symptoms of neurological disorders, such as spasticity caused by conditions such as spastic diplegia, brain palsy and multiple sclerosis or severe muscle spasms caused by dystonia and fibromyalgia. Spasmolytics can also be used to treat other problems, such as serious back pain, which is usually caused by muscle injury and head tension. Spasmolytics affecting a smooth muscle can be used for problems in digestive system, such as irritable colon syndrome.
muscle relaxants can have a significant side effectky. They often cause sedation and fatigue and some have other side effects that may include blurred vision, loss of coordination and stomach problems such as stomach and nausea. In rare cases, some muscle relaxants can cause heart or respiratory failure. Some are also potentially increased after widespread use.
The term muscle relaxant is also sometimes used to indicate a separate group of drugs called neuromuscular blocking drugs. These cause temporary paralysis in skeletal muscles inhibition of production, relaxation or acceptance of acetylcholine neurotransmitter. During surgery, they are served in combination with anesthetics to prevent spontaneous movement.
