Relatively nonselective drugs affect many different tissues or organs. For example, atropine, a drug given to relax muscles in the digestive tract, may also relax muscles in the eyes and in the respiratory tract.

WebA drug target is usually selected depending on the requirements of the problem disease; hence, this step is primarily biologically or biochemically driven. Ideally, the target must be associated with a disease and it must have a suitable binding-pocket/active site into which a drug or drug-like molecule can bind. WebA drug receptor is a specialized target macromolecule that binds a drug and mediates its pharmacological action. These receptors may be enzymes, nucleic acids, or specialized membrane-bound proteins. The formation of the drug-receptor complex leads to a biological response.

WebA focused drug transport aims to extend, localize, target and have a safe drug interaction with the diseased tissue. Objective: The aim of targeted drug delivery is to make the required amount of the drug available at its desired site of action. WebStructure-dependent drug action. The actions of the majority of drugs are intimately related to their three-dimensional chemical structure. Seemingly minor alterations to a drug molecule can result in major changes in pharmacological properties. This can be exploited to develop drugs with a more favorable therapeutic index, fewer side effects ... WebMechanism of Drug Action Most drugs produce their effects by binding to protein molecules. Drug binding often leads to a conformational change in the protein. Four primary drug targets are: ± Ion channels. ± Enzymes. ± Carrier molecules. ± Receptors.
