The IgE-mediated hypersensitivity to Ascaris antigen in reactor rhesus primates is used to assess the pharmacologic profile of Bunaprolast (U-66,858). When Bunaprolast is given by the oral route, it shows dose-related inhibition of resistance (RL) and compliance (Cdyn) changes. When Bunaprolast is given by the aerosol route, it shows dose independent inhibition. In 15 animals, aerosols (52±32 to 53±10% for RL, p=0.05 and 45±19 to 28±19% Cdyn inhibitions, p=0.05) for 5.0-0.1% aerosol. By the oral route, inhibition is seen at 1-4 h following administration. In 5 animals, oral doses of 10 and 5 mg/kg inhibit (RL by 98±2 to 78±1.5%, p=0.01 and Cdyn by 75±17 to 60.9±9.1%, p=0.05) by 10 and 5 mg/kg Bunaprolast, respectively. |
