Sensitization studies with mometasone furoate, tixocortol pivalate, and budesonide in the guinea pig.

Mometasone furoate is a new corticosteroid, synthesized to have an improved ratio of anti-inflammatory potential to adverse effects. The guinea pig maximization test was used to determine the sensitizing capacity of mometasone furoate, and also to investigate cross-reaction patterns in animals sensitized to tixocortol pivalate and budesonide, respectively. Tixocortol pivalate was shown to be a sensitizer in the guinea pig, but cross-reactions to other tested corticosteroids were not observed. Furthermore, no sensitizing capacity could be demonstrated for budesonide or mometasone furoate.
