RESUMO
OBJECTIVE: A basic, powerful and isocratic chiral fluid chromatographic technique was created and approved for the enantiomeric partition of meclizine hydrochloride in pharmaceutical dose structure. METHODS: The chromatographic partition was accomplished on Phenomenex® Lux Cellulose 1 (250 mm x 4.6 mm i.d, 5 µm molecule size) section utilizing portable stage framework containing acetonitrile: 25mM ammonium bicarbonate (75:25%v /v). The versatile stage was siphoned on the segment at the stream pace of 1.0 mL/min, and UV recognition was done at 230 nm. RESULT: The breaking points of recognition and measurement were observed to be 0.25 µg/mL and 1.00 µg/mL individually, for 20µL infusion volume. The alignment bend demonstrated phenomenal linearity over the focus scope of 1-5 µg/mL for (±) meclizine enantiomers with a relationship coefficient (r2 = 0.999). The recuperation investigation of meclizine from tablet plan was observed to be 97.33% and 98.81% separately. Meclizine standard arrangement and versatile stage were observed to be steady for in any event 32h. The meclizine enantiomers were very much settled with mean maintenance times of about (+) Meclizine at 13.14 min and (-) Meclizine at 14.33 min individually. CONCLUSION: The created technique was broadly approved and demonstrated to be hearty, exact, exact and appropriate for the examination of meclizine enantiomers in tablet measurement structure and security investigations of meclizine.
