Pharmacokinetic study on lovastatin sustained-release tablet and sustained-release capsule in Beagal dogs / 华中科技大学学报（医学）（英德文版）

ABSTRACT

This study pharmacokinetically examined the lovastatin sustained-release tablet and sustained-release capsule in Beagle dogs. An reversed-phase HPLC method was established for the determination of lovastatin in Beagle dog plasma. Pharmacokinetic findings were compared among three preparation(lovastatin sustained-release tablet, Tp; sustained-release capsule, TJ and conventional capsule). Our results showed that the pharmacokinetic parameters in 6 dogs after single-dose oral administration of three perparations were calculated. Tmax, Cmax and MRT revealed significant difference (P0.05). It is concluded that the lovastatin sustained-release tablet and sustained-release capsule are able to maintain a sustained-release for 24 h.
