描述 | Reboxetine Mesylate is a selective noradrenaline reuptake inhibitor (NaRI), the first drug of a new antidepressant class[3]. It has a superior pharmacological selectivity to existing tricyclic antidepressants and selective serotonin reuptake inhibitors when tested in a large number of in vitro and in vivo systems[4]. The primary route of reboxetine elimination appears to be through hepatic metabolism. Less than 10% of the dose is cleared renally. A number of metabolites formed through hepatic oxidation have been identified, but reboxetine is the major circulating species in plasma. In vitro studies show that reboxetine is predominantly metabolised by cytochrome P450 (CYP) 3A4; CYP2D6 is not involved. Ketoconazole decreases the clearance of reboxetine, so that the dosage of reboxetine may need to be reduced when potent inhibitors of CYP3A4 are coadministered[5]. Moreover, the antihyperalgesic and antiallodynic effects of reboxetine are mediated by the catecholaminergic system; β2-adrenoceptors; D1-, D2/D3-dopaminergic receptors; and δ-opioid receptors. This analgesic effect of reboxetine, besides its neutral profile on glycemic control, may be advantageous in the pharmacotherapy of diabetic neuropathy-induced pain[6]. Reboxetine was well tolerated during the acute and long-term treatment phase; side-effects such as increased sweating, constipation and dry mouth were the most prominent to be reported[7]. |
