MeSH

structure in first source

Date introduced: January 1, 1976

Agents that inhibit the actions of the parasympathetic nervous system. The major group of drugs used therapeutically for this purpose is the MUSCARINIC ANTAGONISTS.

Year introduced: ANTISPASMODICS & SPASMOLYTICS were see MUSCLE RELAXANTS 1963-1969

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.

Year introduced: 1987

Bicyclic bridged compounds that contain a nitrogen which has three bonds. The nomenclature indicates the number of atoms in each path around the rings, such as [2.2.2] for three equal length paths. Some members are TROPANES and BETA LACTAMS.

Year introduced: 2007

Heterocyclic compounds that contain two rings that share two non-adjacent atoms in common.

Year introduced: 2017(1996)

N-methyl-8-azabicyclo[3.2.1]octanes best known for the ones found in PLANTS.

Year introduced: 1969

Analogs or derivatives of scopolamine.

Year introduced: 1978(1975)

A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.

Year introduced: 1998

A class of organic compounds which contain two rings that share a pair of bridgehead carbon atoms.

Year introduced: 1998

Cyclic compounds that include atoms other than carbon in their ring structure.

Organic chemicals where carbon atoms have been replaced by nitrogen atoms.

Year introduced: 1974(1972)

Organic nitrogenous bases. Many alkaloids of medical importance occur in the animal and vegetable kingdoms, and some have been synthesized. (Grant and Hackh's Chemical Dictionary, 5th ed)

Uses of chemicals which affect the course of conditions, diseases, syndromes or pathology to benefit the health of an individual.

Year introduced: 2004

Activities which affect organs and systemic functions without regard to a particular disease.

Year introduced: 2004

A broad category of chemical actions and uses that result in the prevention, treatment, cure or diagnosis of disease. Included here are drugs and chemicals that act by altering normal body functions, such as the REPRODUCTIVE CONTROL AGENTS and ANESTHETICS. Effects of chemicals on the environment are also included.

Year introduced: 2004(1999)

A group of pharmacologic activities, effects on living systems and the environment, and modes of employment of drugs and chemicals. They are broken into actions, which describe their effects, and uses, which describe how they are employed.

Year introduced: 1999

A subclass of analgesic agents that typically do not bind to OPIOID RECEPTORS and are not addictive. Many non-narcotic analgesics are offered as NONPRESCRIPTION DRUGS.

Year introduced: 1995

Drugs that act on neuronal sensory receptors resulting in an increase, decrease, or modification of afferent nerve activity. (From Smith and Reynard, Textbook of Pharmacology, 1991, p367)

Year introduced: 1998

Drugs that are used to treat RHEUMATOID ARTHRITIS.

Year introduced: 1995

Drugs that act principally at one or more sites within the peripheral neuroeffector systems, the autonomic system, and motor nerve-skeletal system. (From Smith and Reynard, Textbook of Pharmacology, 1991, p75)

Year introduced: 1998
