Brotizolam is indicated for the short-term treatment (2-4 weeks) of severe or debilitating insomnia.
Mode of Action:
There are two primary metabolites: 1-methyl-hydroxy- and the 4-hydroxy-derivatives (Eberts et al., 1981; Boehringer Ingelheim, product information). The 4-hydroxymetabolites have a pharmacological activity which is far less than that of the parent drugs, but the 1-methyl-hydroxymetabolites probably have comparable activity (Gall et al., 1978; Jochemsen et al., 1982; Sethy & Harris, 1982; Jochemsen et al., unpublished results). These active compounds are, however, not present in plasma in measurable amounts following a single dose of brotizolam to young healthy subjects (Jochemsen et al., 1982; Jochemsen et al., unpublished results).
