General pharmacology is the study of the common patterns of drugs pharmacokinetics and pharmacodynamics. Pharmacokinetics1 is the part of pharmacology that deals with compound absorption, distribution in the body, storage, metabolism and excretion (Fig. The main subject of pharmacodynamics2 is the biologic effects of compounds as well as localization and mechanism of action.
The effects of drugs are the result of their interaction with the organism. Therefore, the basic properties defining physiologic activity of the drugs are not the only thing for consideration. The effect of drugs is also dependent on method of use of these compounds as well as the general condition of the organism to which their action is directed.
The other topics for discussion are the most important types of pharmacotherapy, as well as general patterns of drugs' side effects and toxicity.
