Physicians’ and patients’ opinions on the use of generic drugs

low score to the information received on the substitution of a brand name drug by a GD, similar to the results of other studies,[2-5] suggesting the need for greater health education. Possible study limitations include the fact that the results are only applicable to our organizational model and physicians, and cannot be easily generalized to other institutions. One limitation of the study may be due to recall bias, due to the time elapsed between the period of replacement of drug and the realization of the interview. However, all patients were taking a drug at the moment of interview. In conclusion, although the use of GD is vital in order to reduce pharmaceutical expenditure, patients who received substitute generic brands of amlodipine and simvastatin and the physicians who prescribed them both evidenced a worrying lack of information on their use.
