Assessment of quality of post mastectomy analgesic protocol of Gabapentin and Dexmedetomedine in a placebo-controlled study.~Dexmedetomidine is a highly selective X2 adrenergic receptor aganist; it has anxiolytic, sedative, analgesic and sympathdytic properties without significant respiratory depressant effects. Research evidence has shown that this drug protects the body (including heart, nerves, etc.) against ischemia and hypoxic injury. Therefore, dexmedetomidine can be one of the best options for reducing pain after surgery.~Gabapentin, a structural analog of gamma aminobutyric acid, is used as an anticonvulsant drug since 1993. In addition it has been effective in neuropathic pain, diabetic neuropathy and reflex sympathetic dystrophy. It acts through binding to the X-2-5 subvnits of voltagegated calcium ion channels and preventing the central sentization and hyperalgesia. Gabapentin has demonstrated to inhibit the development and establishment of hyperalgesia and secondry allodynia in human volunteers.~Gabapentin may also decrease postoperative obioid requirement through preventing the tolerance development. Furthermore, it has minimal or no effect on gastric mucosa, renal function, and platelets count or activity in the perioperative period to be prefer over nonsteroidal anti-inflammatory drugs.~The Combination of both drugs will be tested for potentiation of post-operative analgesia and decrease of opioid consumptions
