The enantioselectivity of the amylose tris(3,5-dimethoxyphenyl carbamate) p
hase towards some P-blockers was investigated. A sensitive HPLC method was
developed for the enantiomers of metoprolol and betaxolol. The validated me
thods were suitable for the analysis of enantiomeric composition in a varie
ty of pharmaceutical formulations of both drugs.
