One of the key procedures for drug registration in the United States is to study the properties of the drug. The purpose of this study is to obtain reliable information about the effectiveness and safety of a medical device that is planned to be brought to the market, and it consists of several main stages:
-The first stage of the study is the most difficult and responsible stage, which is usually carried out under conditions of open or single-blind observation. In case of open observation, the study drug is used with a known both to the doctor and the subject, and in case of single blind observation, information about the drug used is available only to the doctor. At this stage, tests are carried out using the minimum allowable dose of the drug, at which a safe level of toxicity of the drug is observed. Usually tests are performed on young healthy men without any healthy abnormalities;
-The second stage of research provides for a primary test of the medicinal properties of the drug, so patients suffering from a disease that should be cured by this drug are involved in its implementation. At this stage, the most effective dosages of the drug are also determined and its interaction with other substances is studied;
-The third stage of the study is aimed at obtaining statistical data on the medicinal properties of the drug and its side effects. This requires the involvement of a large sample of patients, which should be representative of the general population. At this stage, the possibility of using the drug in specific patient groups, such as children, is also checked, and conclusions are drawn about its safety;
-The fourth stage is implemented after the registration of the medicinal product and its release to the market. This stage is the stage of post-registration control of the effectiveness and safety of its use. At this stage, data are collected on the use of the drug in real conditions of use and any new side effects or interactions with other drugs that may occur in a larger number of patients are identified. These observations allow further evaluation of the safety and efficacy of the drug in a wider patient population.
The Food and Drug Administration (FDA) is the primary government agency responsible for regulating human drug efficacy and drug testing in the United States.
The FDA authorizes and controls clinical trials involving patients. Companies conducting these studies are required to report to the FDA on the results of the studies.
After completion of clinical trials and receipt of final results, the applicant company provides relevant information to the FDA. The FDA then decides to approve the results and grants a marketing authorization for the drug, or may require additional testing if it believes that the data obtained is insufficiently informative.
In addition, in addition to the characteristics of the drug, the FDA must also agree and approve the technology for its production. Only after the successful completion of this process will the product be released to the market.
The instruction for use is the main document containing information about the properties and use of the drug for consumers, and is subject to strict control by the FDA. The FDA has the authority to approve and approve the following sections of the guidelines:
-Pharmacological properties of the drug, including its interaction with other substances. This section describes how the drug works in the body, its mechanism of action, and how it interacts with other drugs.
- Indications for the use of this drug. It indicates diseases and conditions in which the drug can be effective and its use is recommended.
-Description of side effects and their frequency. This section lists possible side effects of taking the drug, and also indicates how often they can occur.
- Prescriptions for the recommended dosages of the drug, depending on the purpose of its use. It indicates the optimal dose of the drug to achieve the desired effect, as well as recommendations for the frequency of administration and duration of treatment.
All of these sections of the package leaflet are approved and cleared by the FDA to ensure that product information meets safety and efficacy standards.
