AstraZeneca R&D Charnwood (formerly Astra Charnwood, a subsidiary of AstraZeneca) was developing sibenadet (Viozan, AR-C68397AA) for the potential treatment of chronic obstructive pulmonary disease and asthma. Sibenadet is a dual D2 dopamine receptor, beta2-adrenoceptor agonist that combines bronchodilator activity with the sensory afferent modulating effects associated with D2-receptor agonism. Development of sibenadet has been discontinued due to disappointing efficacy findings.

Sample Use Guides

In Vivo Use Guide

701 patients were randomized to one of three sibenadet dose groups (400, 600 or 1000 ug ex valve), salbutamol 200 ug, ipratropium bromide (IB) 40 ug or placebo, all three times daily via pressurized metered dose inhaler (pMDI) for 4 weeks. Once the results of Study 1 had been evaluated, a dose-ranging, study (Study 2) involving 872 patients randomized to receive sibenadet (45, 270, or 495 ug ex actuator), or placebo all three times daily via pMDI, for 6 weeks commenced.

Route of Administration: Respiratory

In Vitro Use Guide

Sibenadet is a weak R1-adrenoceptor agonist (R1(REA): p[A]50 6.08, IA 0.08). It is a dual D2-receptor agonist (D2(REA): p[A]50 8.94, IA 0.90; essentially a full agonist at the D2-receptor) and beta2-adrenoceptor partial agonist (beta2(GPT): p[A]50 7.95
