Abstrakt: Phenothiazine (chloropromazine and promethazine) and antihistamine quinuclidine derivatives [Phencarol, quinuclidyl-d-di-(o-tolyl) carbinol, quinuclidyl-3-di-(o-methoxyphenyl) carbinol hydrochloride (QMCH)], in doses below those liberating histamine, inhibited histamine liberation from the mast cells of rats induced by compound 48/80. QMCH inhibited histamine liberation induced by selective liberators (compound 48/80, MCD-peptide, and specific antigen), but potentiated histamine liberation induced by nonselective liberators (Triton X-100 and chlorpromazine). The inhibitory action of QMCH on histamine liberation induced by compound 48/80 increased for 1 min and was reversible. The inhibitory effect of all the compounds tested was reduced to some extent in the presence of glucose.
