A drug class is a group of medications and other compounds that share similar chemical structures, act through the same mechanism of action (i.e., binding to the same biological target), have similar modes of action, and/or are used to treat similar diseases.
In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. [2] A pharmaceutical drug , also called a medication or medicine, is a chemical substance used to treat , cure, prevent , or diagnose a disease or to promote well-being . [ 3 ]
The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way. Based on drug action on receptors, there are 2 different types of drugs: Agonists – they stimulate and activate the receptors
Side effects can differ within the drug class due to differences in metabolism and pharmacology. For example, long-acting benzodiazepines have problems of drug accumulation especially in the elderly or those with liver disease, and shorter-acting benzodiazepines have a higher risk of more severe withdrawal symptoms.
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
The energy of light is used to change for shape and chemical properties of the drug, resulting in different biological activity. [39] This is done to ultimately achieve control when and where drugs are active in a reversible manner, to prevent side effects and pollution of drugs into the environment. [40] [41]
A medication (also called medicament, medicine, pharmaceutical drug, medicinal drug or simply drug) is a drug used to diagnose, cure, treat, or prevent disease. [1] [2] Drug therapy (pharmacotherapy) is an important part of the medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate ...
The field of pharmacotoxicology also involves the treatment and prevention of pharmaceutically induced side effects. Pharmacotoxicology can be separated into two different categories: pharmacodynamics (the effects of a drug on an organism), and pharmacokinetics (the effects of the organism on the drug).
