Methylcobalamin is an active form of vitamin B12 that helps in synthesis of methionine and S-adenosylmethionine. It is required for integrity of myelin, neuronal function, proper red blood cell formation and DNA synthesis. The largest group of vitamin B12 deficiency is found in typical vegetarians all over the world, which can be alleviated with its analogue Methylcobalamin. It is a beneficial drug to most of the common disorders like cardiovascular disorders, diabetes, anemia, hyperhomocysteinemia and degenerative disorders. Methylcobalamin helps in the synthesis of neuronal lipids, regeneration of axonal nerves and has neuroprotective activity, which promote neurons to function in proper way and thus improves Alzheimer disease, Parkinsonism, Dementia and neuropathic syndromes. It is an approved treatment for peripheral neuropathy.

Pregabalin belongs to a group of medicines known as anti-epileptic medicines, although it is prescribed for the treatment of several different conditions. You may have been prescribed it for the treatment of partial seizures, which are a type of epilepsy. A seizure is a short episode of symptoms which is caused by a burst of abnormal electrical activity in the brain. With a partial seizure, the burst of electrical activity stays in one part of the brain. Therefore, you tend to have localised or 'focal' symptoms. Pregabalin works by reducing the abnormal electrical activity in the brain. It is taken alongside other medicines for epilepsy.
