Abstract:
Objective:To find the reasons for the low dissolution of clarithromycin tablets and study the interference from filter film adsorption at various time points to explore the appropriate processing approach for dissolution solution of clarithromycin tablets. Meth-ods:Clarithromycin tablets from two different manufacturers were used. The dissolution solution was prepared according to Japanese Orange Book. The dissolution was determined after different processing and the adsorption rate of the filter film was calculated. Re-sults:Totally 14 kinds of filter films were tested with different adsorption for clarithromycin, and the adsorption rate of some kinds of filter films exceeded the prescribed limit. Conclusion:The absorption rate of filter films for clarithromycin can be decreased by boiling the films and using American membranes. The interference from filter film adsorption can be reduced and inhibited by rejecting the first filtrate above 5ml or centrifuging dissolution solution.
