Carisoprodol, the active ingredient in Pain O Soma 500, works by blocking signals in the central nervous system that are responsible for coordinating muscle contraction and pain sensation. It acts as a muscle relaxant by blocking the transmission of pain signals from the nerves to the brain. Carisoprodol is well absorbed after oral administration and reaches peak plasma concentrations in 1 to 2 hours. The liver breaks down the medication before the kidneys flush it out of the body. The effects of Pain O Soma 500 usually last between 4 and 6 hours. Pain O Soma 500 should not be used as a long-term treatment for chronic pain because of its addictive qualities. Use it only as directed by a doctor or other qualified healthcare practitioner for the temporary relief of severe musculoskeletal pain. For more information click here Medicationplace.
