A generic drug contains the exact same active ingredients, in equivalent quantities, as the brand-name drug to which it corresponds. Its absorption, diffusion in the body, and effectiveness must be similar to those of its model. But this strictly rational approach is sometimes called into question.
ARE GENERIC DRUGS AS EFFECTIVE AS BRAND-NAME DRUGS?
Sometimes a patient finds the action of a generic less effective than that of the brand-name drug to which he was accustomed. Is it just a prejudice, a distorted perception of reality? Even if they are by definition impossible to verify, such statements deserve in any case to be heard and respected by doctors and pharmacists.
ARE GENERICS THE SUBJECT OF CLINICAL STUDIES?
The marketing authorization which allows the marketing of a generic drug is based on the safety and efficacy data obtained with the original drug. Clinical studies to confirm this efficacy are therefore not necessary. However, as the form and excipients in generic drugs are not always identical to those of the original drug, studies are done to ensure that the generic drug is well absorbed and then eliminated under the same or very similar conditions—those of the original drug.
Medicines are products intended to prevent diseases, to treat them, sometimes even to detect them. They can fight the cause - such as antibiotic drugs for bacterial infections - or alleviate its manifestations, such as analgesics to relieve pain. It acts through one or more active substances associated with excipients (without therapeutic activity) which allow the preparation of the drug.

The prescription makes it possible to obtain the necessary drugs from your pharmacist and to be reimbursed. It is drawn up in two copies: the original and the duplicate, which bears the words "duplicate not allowing the delivery of medicinal products." The pharmacist keeps the duplicate and the address himself at the health insurance fund to be reimbursed for the part you do not pay. You must keep the original of your prescription. It will allow you to follow the treatment carefully and, if necessary, repeat the treatment.
