LIVER HOMOGENATES OF RABBITS CONTAINING (-)-HYOSCYAMINE ACYLHYDROLASE HYDROLYZED (-)-HYOSCYAMINE TO TROPINE AND(-)-TROPIC ACID BUT DID NOT CLEAVE (+)-HYOSCYAMINE.
Despite widespread use over many decades, hyoscyamine has not been linked to episodes of liver enzyme elevations or clinically apparent liver injury. A major reason for its safety may relate to the low daily dose and limited duration of use.
References on the safety and potential hepatotoxicity of anticholinergics are given together after the Overview section on Anticholinergic Agents.

Detection and Identification of Side Reactions of Halogenated Hydrocarbon Solvents with Amines of Pharmaceutical Interest by Secondary Processes to the Neutralizations of Sulphonphthaleinic Dyes with These Amines
generate (dye-, amineH+) and [dye2-, (amineH+)2] ion associates that show two absorption bands in the visible spectrum. An unidentified third absorption band; which appears with a high amine concentration, proves that halogenated hydrocarbon solvents (dichloromethane, chloroform, 1,2-dichloroethane, and carbontetrachloride) give side reactions with amines (atropine, tropine, quinine, ephedrine, and
Cellulose tris(4-phenylazophenylcarbamate) (CPAPC) having azobenzene pendant groups was adsorbed on silica gel to use as a chiral stationary phase for HPLC. Pure trans-CPAPC resolved many racemic compounds, whereas 70% cis-CPAPC showed very poor resolving power.
