GABAPENTIN- GABAPENTIN TABLET TYA PHARMACEUTICALS ---------- GABAPENTIN TABLETS USP DESCRIPTION Gabapentin tablets USP are supplied as oval shaped, film-coated, biconvex scored tablets containing 600 mg and 800 mg of gabapentin USP. The inactive ingredients for the tablets are corn starch, copovidone, poloxamer 407, magnesium stearate, polyethylene glycol, talc, hypromellose, titanium dioxide, macrogol, polysorbate 80 and purified water. Gabapentin USP is described as 1-(aminomethyl) cyclohexaneacetic acid with a molecular formula of C H NO and a molecular weight of 171.24. The structural formula of gabapentin is: Gabapentin USP is a white to off-white crystalline solid with a pK of 3.7 and a pK of 10.7. 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 –1.25. CLINICAL PHARMACOLOGY MECHANISM OF ACTION The mechanism by which gabapentin exerts its analgesic action is unknown, but in animal models of analgesia, gabapentin prevents allodynia (pain-related behavior in response to a normally innocuous stimulus) and hyperalgesia (exaggerated response to painful stimuli). In particular, gabapentin prevents pain-related responses in several models of neuropathic pain in rats or mice (e.g., spinal nerve ligation models, streptozocin-induced diabetes model, spinal cord injury model, acute herpes zoster infection model). Gabapentin also decreases pain-related responses after peripheral inflammation (carrageenan footpad test, late phase of formalin test). Gabapentin did not alter immediate pain-related behaviors (rat tail flick test, formalin footpad acute phase, acetic acid abdominal constriction test, footpad heat irradiation test). The relevance of these models to human pain is not known. The mechanism by which gabapentin exerts its anticonvulsant action is unknown, but in animal test 9172 a1a2 systems designed to detect anticonvulsant activity, gabapentin prevents seizures as do other marketed anticonvulsants.
