Summary

This research is about the effects of drug gabapentin; which is an amino acid that is structurally similar to neurotransmitter GABA. It is a novel drug used for the treatment of postoperative pain with analgesic properties having unique mechanism of action. This study reviews clinical effects of this agent in hand injury patients managed at the Department of Plastics \& Reconstructive Surgery, Dow University of Health Sciences \& Dr. Ruth KM Pfau Civil Hospital Karachi. This study aims to inquire the analgesic properties of gabapentin in the patients and to further investigate its comparison with the equivalent dose of paracetamol given 6 hours after undergoing operative procedure. Acetaminophen is well tolerated when administered in therapeutic dose for pain management. It is a principal drug used as pain reliever and as an antipyretic regimen. This is an experimental study in which a pre-coded questionnaire would be approved in the research for appraising the intensity of pain after intervening operative procedure using visual analogue scale, measuring the pain intensity from 0-10. The questions regarding pain intensity will be inquired after administrating the drug six hours postoperatively. The drug will be prescribed by the doctor on duty having no knowledge regarding the given drug or the group in which he/she is administrating the drug; further questionnaire will be filled by the two co-investigators who will be trained by principal investigator, how to take correct information. Sample size was calculated using www.openepi.com using the previous literature searches of similar research and 50 patients (25 in each group) will be randomly selected from the ward of a known case of hand injury. Group A patients will receive 600 mg of gabapentin post operatively while group B will receive 1 g of paracetamol for management of pain postoperatively orally.

Gabapentin is an anti-convulsion medication and has a high affinity for voltage-gated calcium channel throughout the brain, acts by inhibition of release of excitatory neurotransmitters. As a lipophilic substance, it shows linear pharmacokinetics and has oral bioavailability greater than 90%. Gabapentin is used in a variety of condition as a therapeutic measure involving diabetic neuropathy, post-herpetic neuralgia, in partial seizures, restless leg syndrome, post-menopausal hot flashes, anxiety, resistant mood disorders, essential tremors, and numerous other modalities.
