Clinical Investigation and Analysis of the Combination Use of Western Medicines and Chinese Patent Drugs Containing Salvia Miltiorrhiza or Its Active Ingredients / 中国药师

ABSTRACT

Objective: To understand the combination use and rationality of Chinese patent drugs containing Salvia Miltiorrhiza or its active ingredients and western medicines to provide reference for regulating prescriptions and improving rational drug use level. Methods: The prescriptions of outpatients in our hospital during January 2016 and December 2016 were collected by a retrospective study method, and the ones with the combination use of Chinese patent drugs containing Salvia Miltiorrhiza or its active ingredients and western medicines were analyzed. The rationality of the combination use was analyzed in aspects of physicochemical properties, phar-macological effects, pharmacodynamics and pharmacokinetics. Results: Totally 257 730 prescriptions were examined selectively, and among them, 8 894 were with the combination use of western medicines and Chinese patent medicines containing Salvia Miltiorrhiza or its active ingredients including 1 213 irrational prescriptions (13. 64% ). The irrational prescriptions showed such problems as antago-nism in pharmacologic action causing decreased efficacy (510, 42. 04% ), overlaying in pharmacological effects causing increased effi-cacy (492, 40. 56% ), precipitation because of physical and chemical reactions and chemical taboos (299, 24. 65% ) and reduced bioavailability and affected efficacy due to complex reactions (174, 14. 34% ). Conclusion: The combination use of western medicines and Chinese patent medicines containing Salvia Miltiorrhiza or its active ingredients should be careful to avoid irrational problems. When they are auditing prescriptions and monitoring medication, clinical pharmacists should strengthen intervention of the combination use of Chinese patent medicines and western medicines reasonably combining with physical and chemical properties of medicines, phar-macological effects, pharmacodynamics and other characteristics.
