These include: feeling pain from light pressure or touch, such as clothing hypersensitivity to mildly painful events such as bumps or knocks burning, tingling and pins and needles and abnormal sensations, such as ants crawling under the skin when touched. from Ībout 7% to 8% of adults have chronic pain with neuropathic characteristics. In neuropathic pain, damaged nerve fibres are hyper-excitable. Because it’s often poorly relieved by available medications, the pain is unrelenting and intrudes into all activities of daily living. Patients with persistent nerve pain often describe it as intense burning or shooting sensations in their arms, hands, fingers, legs, feet or toes. Nerve pain is more severe than non-neuropathic pain. This reduces entry of calcium ions into nerve terminals to dampen release of pain neurotransmitter molecules in the spinal cord and brain. Pregabalin (and gabapentin) are thought to interact with specific proteins in nerve endings in the brain and spinal cord. In neuropathic pain, damaged nerve fibres are hyper-excitable, which means sensations such as light pressure or touch, which are normally barely felt, are perceived as painful. In Australia, it was registered by the Therapeutic Goods Administration in 2005. In 2007, pregabalin was approved in the United States to treat fibromyalgia, a chronic disorder characterised by pain and muscle tenderness throughout the body.

Lyrica was approved in 2004 in the United States for the treatment of partial seizures of epilepsy and some neuropathic pain. This makes the effects of pregabalin more predictable than those of gabapentin.īoth are recommended as first line treatments for nerve pain by the International Association for the Study of Pain. The amount of pregabalin absorbed into the bloodstream increases in a linear fashion unlike gabapentin where as the dose goes up, the proportion absorbed into the bloodstream goes down. Subsequently, pregabalin was developed as an improved version of gabapentin. By Acdx (Own work), via Wikimedia Commons, CC BY
