In Vitro | In vitro activity: The presence of BV at a concentration of 4.6 mM/l provoked a still further diminuition of the G-6-PDH-activity of human skin homogenates that followed the incubation for 120 min at 37°C in media containing 5% dimethylformamide and in which the concentration of G-6-PDH changed from about 55 mU/ml to 9 mU/ml. |

In Vivo | Compared with sodium cromoglycate (SCG, 80mg daily), treatment of betamethasone valerate (BV, 800μg daily) for 4 weeks made children requiring bronchodilators for perennial asthma significantly require less bronchodilator drugs, and have fewer symptoms and higher daily peak expiratory flow rates. Compared with coal tar (10% LCD) cream, after a 2 week wash-out period, treatment with betamethasone valerate cream (0.1%) twice daily for 6 weeks made patients with stable, mild-moderate plaque psoriasis get more mean reduction of PASI score from baseline. The final effect of betamethasone valerate was significantly greater clearance and improvement . |
