Study on dissolution behavior in vitro of an osteoporosis treatment drug: eldecalcitol soft capsule
Objective:To establish a method for the dissolutions profile determination of Eldecalcitol softgels, evaluate the in vitro dissolutions behavior between domestic Eldecalcitol soft capsules and the original preparation。Methods:The effects of different stirring apparatus, different dissolutions medium, different agitation speeds on the dissolutions behavior of Eldecalcitol soft capsules were investigated, cumulative dissolutions were calculated by measuring the dissolutions samples with HPLC-MS/MS method. Results:The dissolutions test of Eldecalcitol soft capsules was carried out by rotating basket method, agitation speed of 75 rpm, temperature of 37℃ in four mediums。Conclusion:This dissolutions method can be effectively applied to the dissolutions test of soft Eldecalcitol capsules. and the selected generics have good dissolution consistency with the original drugs.
Keywords:Eldecalcitol soft capsules;dissolutions method;dissolutions behavior;consistency evaluation
期刊介绍:
The international journal of the Polish Pharmaceutical Society is published in 6 issues a year. The journal offers Open Access publication of original research papers, short communications and reviews written in English, in all areas of pharmaceutical sciences. The following areas of pharmaceutical sciences are covered: Analysis, Biopharmacy, Drug Biochemistry, Drug Synthesis, Natural Drugs, Pharmaceutical Technology, Pharmacology and General.
A bimonthly appearing in English since 1994, which continues “Acta Poloniae Pharmaceutica”, whose first issue appeared in December 1937. The war halted the activity of the journal’s creators. Issuance of “Acta Poloniae Pharmaceutica” was resumed in 1947. From 1947 the journal appeared irregularly, initially as a quarterly, then a bimonthly. In the years 1963 – 1973 alongside the Polish version appeared the English edition of the journal. Starting from 1974 only works in English are published in the journal. Since 1995 the journal has been appearing very regularly in two-month intervals (six books a year). The journal publishes original works from all fields of pharmacy, summaries of postdoctoral dissertations and laboratory notes.
