Determination of Four Nadolol Stereoisomers in Capsules by High-Performance Liquid Chromatography and Circular Dichroism.

Nadolol is a blocking agent with activity in β-adrenergic receptors. The objective of this research was to develop and validate an HPLC and circular dichroism method for the quantification of four nadolol stereoisomers in capsules. The HPLC method was validated using a Chiralcel OD column (250 × 4,6 mm, 10 μm).
