DRUGS & SUPPLEMENTS
Obirax is an drug for the treatment of central action obesity. The mechanism of action is due to selective inhibition of serotonin reuptake of norepinephrine and, to a lesser extent, of dopamine. This medication accelerates the onset and prolong satiety, which leads to a decrease in food consumption. It increases energy expenditure by stimulating thermogenesis mediated by activation of beta3-adrenergic receptors. Acts on both sides of the balance of energy and helps reduce body weight.
Sibutramine and its metabolites did not release monoamines, and they are not MAO inhibitors, have no affinity for serotonergic, adrenergic, dopaminergic, muscarinic, histamine, benzodiazepine and NMDA receptors.
After oral administration Obirax is rapidly absorbed from the gastrointestinal tract. Almost completely metabolized in the liver, with the participation of cytochrome isozymes CYP3A4, as well as by hydroxylation and conjugation to form inactive metabolites. Cmax of sibutramine is achieved in 1.2 h. This medicine is quickly and widely distributed in tissues. The plasma protein binding is 97%. T1/2 is 1.1 h. Obirax derived primarily by the kidneys as inactive metabolites.
