Description:
Pregabalin is described chemically as (S)-3-(aminomethyl)-5-methylhexanoic acid. The molecular formula is C8H17NO2 and the molecular weight is 159.23.

Pregabalin is a white to off-white, crystalline solid with a pKa1 of 4.2 and a pKa2 of 10.6. It is freely soluble in water and both basic and acidic aqueous solutions. The log of the partition coefficient (n-octanol/0.05M phosphate buffer) at pH 7.4 is 1.35.

Application
1. Pregabalin is an anticonvulsant drug used for neuropathic pain, as an adjunct therapy for partial seizures, and in generalized anxiety disorder. It was designed as a more potent successor to gabapentin. Pregabalin is marketed by under the trade name.

2. Pregabalin is used to relieve neuropathic pain (pain from damaged nerves) that can occur in your arms, hands, fingers, legs, feet, or toes if you have diabetes or in the area of your rash if you have had shingles (a painful rash that occurs after infection with herpes zoster).

3. It is also used to treat fibromyalgia (a long-lasting condition that may cause pain, muscle stiffness and tenderness, tiredness, and difficulty falling asleep or staying asleep).

4. Pregabalin is used with other medications to treat certain types of seizures in people with epilepsy.

5. Pregabalin is in a class of medications called anticonvulsants. It works by decreasing the number of pain signals that are sent out by damaged nerves in the body.


Efficiency:

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 is 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 is also prescribed to treat certain types of long-lasting pain caused by damage to nerves. This type of pain, called neuropathic pain, can be caused by a number of different conditions, including diabetes (where it is called diabetic neuropathy) and shingles(where it is called postherpetic neuralgia).
