Pharmacology is the science of drugs and medications, [1] including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. [ 2 ]
Their new text was first published in 1941 under the title The Pharmacological Basis of Therapeutics: A Textbook of Pharmacology, Toxicology and Therapeutics for Physicians and Medical Student. [1] Because the volume was twice as long as a typical textbook, Macmillan printed few copies, but demand for a readable, up-to-date pharmacological text ...
The IUPHAR/BPS Guide to PHARMACOLOGY is an open-access website, acting as a portal to information on the biological targets of licensed drugs and other small molecules. The Guide to PHARMACOLOGY (with GtoPdb being the standard abbreviation) is developed as a joint venture between the International Union of Basic and Clinical Pharmacology (IUPHAR) and the British Pharmacological Society (BPS).
Topics of pharmacodynamics. Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs).The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection).
In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. [1] These signals are typically chemical messengers [nb 1] which bind to a receptor and produce physiological responses such as change in the electrical activity of a cell.
In the fields of medicine, biotechnology, and pharmacology, drug discovery is the process by which new drugs are discovered. [citation needed] Historically, drugs were discovered by identifying the active ingredient from traditional remedies or by serendipitous discovery.
Explore the concept of PK/PD models, which integrate pharmacokinetics and pharmacodynamics to optimize drug dosing and efficacy.
In pharmacology, the area under the plot of plasma concentration of a drug versus time after dosage (called “area under the curve” or AUC) gives insight into the extent of exposure to a drug and its clearance rate from the body. [2]
