There are many lines of research related to pharmacology, ranging from the study of the effects of drugs, to the creation of new ones capable of mitigating the symptoms of diseases, whether they are new or already known diseases. Drugs have to undergo many controls and tests to demonstrate their safety and effectiveness before reaching patients. It is essential to analyze all possible adverse effects to assess whether they can be circulated and to whom they can be administered. In recent times we have confirmed the importance of research in the treatment of diseases. A clear example is vaccines, the only way to stop infections. Time and support is what professionals need to carry out their work without pressure and achieve the best results.
