GENERAL CONSIDERATIONS :

 

Pharmacology is the study of the effects of drugs on living systems. It attempts to characterize the biological actions of chemical and to define the mechanisms by which these actions are evoked. A pharmacologist seeks to describe and quantify both the desirable and undesirable effects in laboratory animals and to establish the conditions under which such observations can be extrapolated to the human population. Experimental pharmacology thus helps in understanding the nature of drug action and the vulnerability of the living systems to the alternation by chemicals that serves as the basis on which a) New therapeutic agents are developed, and b) Toxic consequences of chemical exposure may be alleviated.

 

The experiments can be carried out in whole animal (In-vivo) or in isolated organs(In-vitro). In whole animal experiments (e.g. Dog-blood pressure) the effect of drugs on any organ is influenced by many factors such as metabolic state, blood supply, nervous control, hormonal influences, factors of bio-availability etc. It is difficult to estimate and control the influences of such a diversity of factors. Elucidation of action of drug may be hindered in such cases. The use of isolated ‘ in vitro’ preparations provides distinct advantage to facilitate the experimental investigations concerning mode of actions of drugs. The experimental conditions can be well controlled precisely in these experiments.

 

The effect of drug can be studied independent of other systems thus relating direct mechanism of action of drug. The isolated preparations are commonly used in experiments because of these advantages. The intact experiments (i.e. whole animal experiments) are also of importance to study the effect of drugs, the interaction between two drugs and between the body factors and drugs.

 

Before starting experiments in pharmacology it is essential to understand about laboratory and experimental animal . One should also know about their maintenance and handling.
