Betamethasone valerate (BV or BET), also called betamethasone 17-valerate [2], is a commonly used anti-inflammatory corticosteroid, used to manufacture dermatological drug products for topical applications [3] [1]. Its IC50 in normal rats is 3.4±0.5 nM [4].  BV can reduce glucose-6-phosphate dehydrogenase (G-6-PDH) activity in vitro [5].
G-6-PDH (EC. is an enzyme that catalyzes the first step in the pentosephosphate pathway [6].
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 [5].
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 [7]. 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 [8].
