What is muscle relaxants used for?

Muscle relaxers are used in addition to rest, physical therapy, and other measures to relieve discomfort. They are typically prescribed for short-term use to treat acute, painful musculoskeletal conditions. Muscle relaxers are occasionally prescribed for chronic pain (pain lasting longer than 3 months).

What drugs relax smooth muscle?

The most frequently used drugs in the therapy of visceral smooth muscle spasms are substances that relax smooth muscles (with antimuscarinic activity/atropine-like/or with non-specific activity/papaverine-like direct spasmolytics) and analgesics (opioids or nonsteroid antiinflammatory drugs-NSAID).

How do skeletal muscle relaxants work?

Some of the ways in which skeletal muscle relaxants work to relax skeletal muscles include the following: Inhibit afferent nerves from releasing excitatory neurotransmitters. Inhibit the activity of interneurons which connect the afferent and efferent nerves, and prevent transmission of nerve signals.

Do muscle relaxers work on smooth muscle?

Smooth-muscle relaxants include those directly affecting intestinal smooth muscle relaxation (e.g., mebeverine, pinaverium) and those that act in a similar fashion via anticholinergic pathways (e.g., dicyclomine, hyoscyamine).

Are muscle relaxants safe?

Serious side effects associated with their use include dizziness, falls, fractures, car accidents, dependence and overdose. Muscle relaxants pose a significant risk to people over 65, and the American Geriatrics Society advises against their use in this age group.

Do muscle relaxers effect your heart?

Effects on the heart warning: This drug may cause heart arrhythmias (heart rate or rhythm problems). Your risk may be higher if you take a drug to treat depression or if you already have heart problems. If these issues aren’t treated, they can lead to a heart attack or stroke.

What causes spasm?

Muscle pain, fatigue, and overuse are the most common causes of muscle spasms. Other causes include stress or anxiety, which can lead to muscle twitches in the face. Trapped nerves can result in spasms in the back.

Can muscle relaxers cause paralysis?

Neuromuscular blockers act by interfering with transmission at the neuromuscular end plate and have no central nervous system (CNS) activity. They are often used during surgical procedures and in intensive care and emergency medicine to cause temporary paralysis.

Do muscle relaxers cause low blood pressure?

Methocarbamol and other muscle relaxants can also cause a specific type of hypotension called orthostatic hypotension, which causes lightheadedness when you stand from sitting or lying down. This is usually a mild symptom, but it can lead to fainting and injury.

Do muscle relaxers make you sleepy?

Muscle relaxants are ideally prescribed for acute rather than chronic pain. They may be an option if pain is preventing you from getting enough sleep. Because muscle relaxants cause drowsiness, they can help you get rest when you take them at night.
