What is Methocarbamol for?

As we said in the introduction, Methocarbamol is a drug that works as a muscle relaxant. Its functionality is not yet fully known, but it is believed with certainty that it blocks painful impulses to the central nervous system at the level of the spinal cord. This prevents neurotransmitters, responsible for communicating pain signals, from activating muscle fibers. It is very common to use this medicine to treat skeletal-muscular problems, such as sprains, strains, fractures, bumps and contractures. It is also an antispasmodic drug, therefore it usually helps in the fight against tetanus (a disease caused by the bacteria clostridium). Finally, it is very normal to combine it with paracetamol to help relieve discomfort,

Treatment of torticollis, tendonitis and bursitis:  Torticollis and neck pain due to stress are usually combated by Methocarbamol, since it helps to relax the muscles, distend the tendons and begin to reduce inflammation. The same effects apply to tendonitis and bursitis, as it blocks pain and begins to eradicate inflammation.

Its use in tetanus, spasms and contractures:  We have already said that this drug is a natural relaxant, which is equivalent to preventing the muscles from contracting and tensing causing pain, from which it derives that it is used for spasms and contractures. As for tetanus, it clearly does not affect the pathology itself, but anyway by relaxing the muscles it allows other drugs to act as they should. It is widely used on horses.
