生物活性

製品説明 Arformoterol Tartrate is the tartrate salt of arformoterol, a long-acting beta-2 adrenergic agonist with bronchodilator activity.
in vivo Arformoterol (R,R-formoterol) is a active isomer of racemic formoterol and is indicated for the long-term, maintenance treatment of bronchoconstriction in patients with COPD including chronic bronchitis and emphysema. It is a potent and selective agent which causes bronchial smooth muscle relaxation and inhibits the release of inflammatory mediators. Its pharmacological effects can be attributed to the increased intracellular cyclic adenosine monophosphate (cAMP) levels that result from the stimulation of intracellular adenyl cyclase. Arformoterol tartrate is well absorbed through lungs when administered by a nebulizer. The mean peak plasma concentration (Cmax) and systemic exposure (AUC0-12h) are 4.3 pg/mL and 34.5 pg.h/mL, respectively, when 15 µg arformoterol is administered every 12 h for 14 days in COPD patients. The time to achieve median steady state peak plasma concentration (tmax) is approximately half an hour after drug administration. The mean terminal half-life is 26 h in COPD patients when treated with 15 µg inhaled arformoterol twice daily for 14 days. The binding of arformoterol to human plasma proteins in vitro is 52-65% at concentrations of 0.25, 0.5 and 1.0 ng/mL of radiolabeled arformoterol. Metabolism occurs primarily by direct conjugation (glucuronidation) and secondary route of metabolism is via O-demethylation. Metabolism is mediated by atleast five human uridine diphosphoglucuronosyltransferase (UGT) isozymes as well as CYP2D6 and CYP2C19. After administration of a single oral dose of radiolabeled arformoterol, 63% of the radioactive amount was recovered in urine and 11% in feces within 48 h. A total of 89% of the total radioactive dose was recovered within 14 days, with 67% in urine and 22% in faeces[1].
