CHEMISTY IN EVERYDAY LIFE
➱ Drugs : Drugs are the chemical substances of low molecular mas, interact with macromolecular targets and produce a biological response.
➱ Medicines : Drugs which produce a therapeutic and useful response.
➱ Chemotherapy : It is the science in which chemicals are used in the treatment of diseases due to bacterial invasion.These chemicals destroy the micro-organisms without affecting any material extent, the tissues of the host).
➱ Classification of Drugs :
(i) On the basis of pharmacological effect : Most useful for doctors as it provides the whole range of drugs available for the treatment of a particular type of problem. e.g., analgesics have pain killing effect, antiseptics kill or arrest the growth of microorganisms.
(ii) On the basis of drug action : It is based on the action of a drug on a particular biochemical process. e.g., all histamines inhibit the action of the compound histamines, which causes inflammation of the body.
(iii) On the basis of chemical structure : Drugs which have common structural features and often have similar pharmacological activity. e.g., sulphonamides have common structural feature.
