Tramadol hydrochloride extended-release tablets are a centrally acting synthetic opioid analgesic. Although its mode of action is not compley understood, at least two complementary mechanisms that demonstrate three different types of activity appear applicable: binding of parent and M1 metabolite to µ-opioid receptors.
Following a single oral dose of immediate-release tramadol, and after adjusting for body weight, females had a 12% higher peak tramadol concentration and a 35% higher area under the concentration-time curve compared to males. Following a 100 mg IV dose of tramadol, plasma clearance was 6.4 mL/min/kg in males and 5.7 mL/min/kg in females. The clinical significance of this difference is unknown.

Concomitant administration of tramadol immediate-release tablets with cimetidine does not result in clinically significant changes in tramadol pharmacokinetics.

Administration of tramadol elicited an antidepressant-like effect in the rat forced swimming test (FST) by a mechanism dependent on the inhibition of the L-arginine-nitric oxide (NO)-guanylate cyclase pathway. Since it has been reported that NO can activate different types of potassium (K+) channels in.

Conversely, pretreatment with apamin (a small-conductance calcium-activated K+ channel inhibitor, 10 pg/site) did not modify the action of a subeffective dose of tramadol (1 mg/kg, p.o.). Since it has been reported that NO can activate different types of potassium (K+) channels in several tissues, the present study investigated the possibility of synergistic interactions between different types of K+ channel inhibitors and tramadol in the mouse FST. Administration of tramadol and the K+ channel inhibitors, alone or in combination, did not affect the number of crossings and rearings in the open field test (OFT). Administration of tramadol elicited an antidepressant-like effect in the rat forced swimming test (FST) by a mechanism dependent on the inhibition of the L-arginine-nitric oxide (NO)-guanylate cyclase pathway. Reduction in the immobility time elicited by an active dose of tramadol (40 mg/kg, p.o.) in the FST was prevented by pretreatment of mice with cromakalim (a K+ channel opener, 10 µg/site, i.c.v.), without affecting the number of crossings and rearings in the OFT. Intracerebroventricular pretreatment of mice with tetraethylammonium (TEA, a non-specific inhibitor of K+ channels, 25 pg/site), glibenclamide (an ATP-sensitive K+ channel inhibitor, 0.5 pg/site) or charybdotoxin (a large- and intermediate conductance calcium-activated K+ channel inhibitor, 25 pg/site) was able to produce a synergistic action of a subeffective dose of tramadol (1 mg/kg, p.o.). Thus, our findings clearly suggest that oral acute administration of tramadol produces antidepressant-like effect on the FST in mice by a mechanism that involves the K+ channels.
