Goodman & Gilman's The Pharmacological Basis of Therapeutics, commonly referred to as the Blue Bible or Goodman & Gilman, is a textbook of pharmacology originally authored by Louis S. Goodman and Alfred Gilman. First published in 1941, the book is in its 14th edition (as of 2022), and has the reputation of being the "bible of pharmacology".
Pharmacology can be applied within clinical sciences. Clinical pharmacology is the application of pharmacological methods and principles in the study of drugs in humans. [21] An example of this is posology, which is the study of dosage of medicines. [22] Pharmacology is closely related to toxicology.
[1] [2] Clinical pharmacology is inherently a translational discipline underpinned by the basic science of pharmacology, engaged in the experimental and observational study of the disposition and effects of drugs in humans, and committed to the translation of science into evidence-based therapeutics.

Upon drug binding, receptors can elicit their normal action (agonist), blocked action (antagonist), or even action opposite to normal (inverse agonist). In principle, a pharmacologist would aim for a target plasma concentration of the drug for a desired level of response. In reality, there are many factors affecting this goal.
Pharmacotherapy, also known as pharmacological therapy or drug therapy, is defined as medical treatment that utilizes one or more pharmaceutical drugs to improve ongoing symptoms (symptomatic relief), treat the underlying condition, or act as a prevention for other diseases (prophylaxis).
The phrase "drug design" is similar to ligand design (i.e., design of a molecule that will bind tightly to its target). [6] Although design techniques for prediction of binding affinity are reasonably successful, there are many other properties, such as bioavailability, metabolic half-life, and side effects, that first must be optimized before a ligand can become a safe and effictive drug.
Receptor theory is the application of receptor models to explain drug behavior. [1] Pharmacological receptor models preceded accurate knowledge of receptors by many years. [ 2 ] John Newport Langley and Paul Ehrlich introduced the concept that receptors can mediate drug action at the beginning of the 20th century.
Drug antagonism refers to a medicine stopping the action or effect of another substance, preventing a biological response. [ 1 ] [ 2 ] The stopping actions are carried out by four major mechanisms, namely chemical, pharmacokinetic , receptor and physiological antagonism . [ 2 ]
