propofol

An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes. (From Smith and Reynard, Textbook of Pharmacology, 1992, 1st ed, p206). Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.
MSH

A hypnotic alkylphenol derivative. Formulated for intravenous induction of sedation and hypnosis during anesthesia, propofol facilitates inhibitory neurotransmission mediated by gamma-aminobutyric acid (GABA). This agent is associated with minimal respiratory depression and has a short half-life with a duration of action of 2 to 10 minutes.

propoxykain

A local anesthetic of the ester type that has a rapid onset of action and a longer duration of action than procaine hydrochloride. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1017)
MSH

A para-aminobenzoic acid ester with local anesthetic activity. Propoxycaine binds to and inhibits voltage-gated sodium channels, thereby inhibiting the ionic flux required for the initiation and conduction of impulses. This results in a loss of sensation.

dextropropoxyfen

The d-isomer of synthetic diphenyl propionate derivative propoxyphene, with narcotic analgesic effect. This agent mimics the effects of the endogenous opiate dextropropoxyphene, by binding to mu receptors located throughout the central nervous system. The binding results in GTP to GDP exchanges on the mu-G-protein complex, by which effector adenylate cyclase is inactivated thereby decreasing intracellular cAMP. This, in turn, inhibits the release of various nociceptive neurotransmitters, such as substance P, gamma-aminobutyric acid (GABA), dopamine, acetylcholine, noradrenaline, vasopressin, and somatostatin. In addition, dextropropoxyphene closes N-type voltage-gated calcium channels and opens calcium-dependent inwardly rectifying potassium channels. This results in hyperpolarization, thereby reducing neuronal excitability, which further decreases the perception of pain.
NCI

A narcotic analgesic structurally related to METHADONE. Only the dextro-isomer has an analgesic effect; the levo-isomer appears to exert an antitussive effect.

propoxyphene napsylate

A synthetic diphenyl propionate derivative structurally related to methadone, Propoxyphene Napsylate acts as a central narcotic and analgesic agent by interaction with mu opioid receptors, but with less selectivity then morphine. The dextro-isomer has analgesic effect, while the levo-isomer exerts an antitussive effect. The napsylate salt allows better dosage formulation than the hydrochloride salt. (NCI04)

propranolol

A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.
MSH

noncardioselective beta adrenergic antagonist; used in treatment or prevention of many disorders including acute myocardial infarction, arrhythmias, angina pectoris, hypertension, hyperthyroidism, migraine; pheochromocytoma, etc.
CSP

A synthetic, nonselective beta-adrenergic receptor blocker with antianginal, antiarrhythmic, antihypertensive properties. Propranolol competitively antagonizes beta-adrenergic receptors, thereby causing negative chronotropic and inotropic effects leading to a reduction in cardiac output.

propriocepce

Sensory functions that transduce stimuli received by proprioceptive receptors in joints, tendons, muscles, and the INNER EAR into neural impulses to be transmitted to the CENTRAL NERVOUS SYSTEM. Proprioception provides sense of stationary positions and movements of one`s body parts, and is important in maintaining KINESTHESIA and POSTURAL BALANCE.
MSH

The series of events by which an organism senses the position, location, orientation, and movement of the body and its parts. Proprioception is mediated by proprioceptors, sensory nerve terminals found in muscles, tendons, and joint capsules, which give information concerning movements and position of the body. The receptors in the labyrinth are sometimes also considered proprioceptors. [http://www.onelook.com/, ISBN:072168677X]

propylhexedrine

A propylamine derivative with sympathomimetic property. Propylhexedrine binds to and activates alpha-adrenergic receptors in the mucosa of the respiratory tract, thereby mimicking the actions of norepinephrine and epinephrine. This results in vasoconstriction and reduces swelling and inflammation of the mucous membrane lining, therefore relieving nasal and sinus congestion.

propylthiouracil

A thiourea antithyroid agent. Propythiouracil inhibits the synthesis of thyroxine and inhibits the peripheral conversion of throxine to tri-iodothyronine. It is used in the treatment of hyperthyroidism. (From Martindale, The Extra Pharmacopeoia, 30th ed, p534)
MSH

A thiourea derivative with antithyroid property. Propylthiouracil (PTU) interferes with the oxidation of iodine possibly by interaction with peroxidase or a peroxidase-mediated complex reaction, thereby inhibiting synthesis of thyroid hormones tri-iodothyronine (T3) and thyroxine (T4). In addition, this agent inhibits the Type I 5`-deiodinase (D1), an enzyme involved in the peripheral conversion of thyroxine to tri-iodothyronine. This results in decreased plasma triodothyronine concentrations and decreased entrance of thyroxine into cells thereby reducing thyroid hormone activity.
