tixocortol-pivalate and betamethasone-sodium-phosphate

Tixocortol pivalate is a corticosteroid with topical anti-inflammatory activity equal to that of hydrocortisone. It was evaluated in a group of 18 normal subjects to determine whether it exerted any systemic glucocorticoid activity after single oral or intrarectal doses and after short-term dosing by the intranasal route. Effects of tixocortol pivalate were compared to those of oral dexamethasone and intrarectal betamethasone 21-phosphate. By the three routes, tixocortol pivalate does not induce any changes in plasma cortisol, leukocyte counts (neutrophils, lymphocytes, monocytes, eosinophils), blood glucose, or 24-hr urinary excretion of sodium and potassium, whereas there were changes after dexamethasone and betamethasone. Tixocortol pivalate, however, increased urinary free cortisol-like substances. It is concluded that tixocortol pivalate given for short periods by nonparenteral routes does not induce a measurable systemic glucocorticoid effect.
