They have a specific effect on certain organs: in particular, on the skin; hypothalamic-pituitary system; bones; intestinal wall and intestinal smooth muscle; nervous system, etc. The characteristic effects of these biochemical drugs are explained by their specific properties both in health and in disease. Their actions are called **specific**. Not all substances exhibit specific actions; they are expressed differently and manifest differently in different people. These properties of the biological properties of drugs explain the nature of specific reactions.
