[How practitioners view generic drugs: an opinion study from general practitioners in Maine-et-Loire (France)]

Abstract

Introduction: Generic drugs are copies of original drugs, hence their low cost. In France, expansion of the use of generic drugs is not significant and the support of practitioners is essential in increasing this.

Aim: The purpose of this study was to survey the opinion and practical experience of physicians regarding generic drugs, in order to develop a proposal for the safer use of these drugs.

Methods: A form was sent to the 1235 general and specialist practitioners in the Maine-et-Loire "département" with assistance from the regional health insurance, in March 2002. The main topics studied were prescribing practices, risks associated with generic drugs and pharmacist substitutions. The chi2 test and Fisher's exact test were used in the data analysis.

Results: Four hundred and twenty-nine forms were returned (34.7%). Only 55% of practitioners considered generic drugs to be as safe and effective as original drugs. Fifty-nine percent prescribe generics rarely or never. The prescribing depends on many factors, linked to the practitioner, the patient or the drug. Many practitioners reported adverse events with generic medicines. With regard to the switch by the pharmacist, it was reported that 45% of prescribers would refuse it in some instances. Among the proposals, cooperation between practitioners and pharmacists in the choice of the generic drugs was approved by 57% of physicians.

Discussion: The main perception is that the vastness of the generic world and the fear of adverse events are somewhat bewildering for both patients and health professionals. Among the proposals made by practitioners, a decrease in the number of generics for a same molecule and the institution of a standard price are widely approved.

Conclusion: Practitioners do not refuse to use generic drugs but are very concerned about the risks of adverse effects for their patients. They regard it as important that a patient receiving chronic treatment be given the same generic drug each time.
