How Regab 25 works

Regab 25 is an antiepileptic medication. When given for epilepsy, it is believed to work by reducing the abnormal electrical activity in the brain, thus preventing seizures. It is also used to treat nerve pain where it blocks pain by interfering with pain signals travelling through the damaged nerves and the brain. For treatment of anxiety, it is believed to work by stopping the release of certain chemical messengers (neurotransmitters) that make you feel anxious.

Mode of Action

Pregabalin is an analog of the neurotransmitter GABA. It binds potently to the alpha2-delta subunit resulting in modulation of Ca channels and reduction in the release of several neurotransmitters, including glutamate, norepinephrine, serotonin, dopamine, calcitonin gene-related peptide and substance P.

Precaution

Abrupt or rapid discontinuation of Pregabalin may produce some symptoms including insomnia, nausea, headache and diarrhoea. So Pregabalin should be tapered gradually over a minimum of 1 week rather than discontinued abruptly. Pregabalin treatment may associate with creatine kinase elevations. It should be discontinued if myopathy is diagnosed or suspected or if markedly elevated creatine kinase levels occur. Discontinue treatment if patients develop severe angioedema. Regular vision check is recommended. May decrease platelet count and prolong PR interval. Patient w/ history of angioedema episodes, severe CV disease, renal impairment. Pregnancy and lactation.
