Anti-inflammatory mechanism of alminoprofen: action on the phospholipid metabolism pathway.

Alminoprofen is a nonsteroidal anti-inflammatory drug (NSAID) of the phenylpropionic acid class. It has anti-inflammatory properties different from the classical NSAID. Using both in vitro systems of cells in culture and in vivo models of inflammation, we report here that alminoprofen possesses both antiphospholipase A2 (PLA2) activity and anti-cycloxygenase (COX) activity.

Pharmacokinetics of 2-(p-methylallylaminophenyl) propionic acid, alminoprofene, in man after single and multiple oral doses.

2-(p-methylallylaminophenyl) propionic acid, alminoprofene (INN), a new antalgic drug, was administered orally to men as a single (300 mg) and multiple doses (300 mg three times daily). Plasma and urine concentrations of alminoprofene were determined by gas-liquid chromatography. After the single oral dose, the peak plasma level (36.

[Anti-inflammatory effect of aluminum or aurin tricarboxylic acid].

The anti-inflammatory effect of aurin tricarboxylic acid is studied in rats after parenteral injection of 20 and 50 mg/kg. Aurin tricarboxylic acid reduces: the carrageenan-induced oedemas in paws, the carragenan-induced pleural effusion, the carragen-induced granulation tissue growth and the Freund adjuvant-induced arthritis. As non steroïdal antiinflammatory drugs, the aurin tricarboxylic acid inhibits (ED50 = 0.

The pharmacology of 1841 CERM, a new analgesic.

A new non-narcotic analgesic, 2(3-trifluormethyl)-phenyl-tetrahydro-1,4-oxazine (1841 CERM) was compared with morphine, codeine and acetylsalicylic acid (ASA) in various pharmacological tests for analgesic activity. Studies for possible tolerance and physical dependence liability were also carried out. In these tests, 1841 CERM was a more powerful analgesic than morphine, and particularly codeine when given orally.

Cardiovascular pharmacology of bepridil (1[3 isobutoxy 2 (benzylphenyl) amino] propyl pyrrolidine hydrochloride) a new potential anti-anginal compound.

In dogs intravenous bepridil (2.5 mg/kg) increased coronary sinus blood flow and PVO2. Arterial pressure was briefly lowered, and heart rate was slowed in animals with intact or denervated hearts, or after propranolol administration.

Influence of hypercapnia on the cerebrovascular activities of some drugs used in the treatment of cerebral ischemia.

The effects of twelve substances on local cerebral blood flow (LCBF) were studied in the normocapnic and hypercapnic conscious rabbit. In normocapnia, an increase in LCBF was observed after naftidrofuryl (NAF), cinnarizine (CI), viquidil (VI) and heptaminol acefyllinate (HA). The LCBF was only slightly increased or unchanged after hydrogenated ergot alkaloids (HEA), cyclandelate (CY), hexobendine (HE), ifenprodil (IF), piridoxilate (PI), vincamine (VC) and xantinol niacate (XN).

General pharmacological properties of a new non-opiate antitussive: zipeprol (3024 CERM). I. Action on respiratory function and acute toxicity.

1-(2-Methoxy-2-phenyl)-ethyl-4-(2-hydroxy-3-methoxy-3-phenyl)-propyl-iperazine-dihydrochloride (zipeprol, Respilene) is a substance of non-phenanthrenic chemical structure. In the cat, it antagonised cough induced by stimulation of the superior laryngeal nerve or by direct mechanical excitation of the sensitive tracheo-bronchial receptors. The efficacy of zipeprol after enteral administration made it possible both to establish good intestinal absorption and to rank it favourably in relation to several major antitussive reference products; codeine, codethyline, dextromethorphan, diphenhydramine and pentoxyverine.

Urinary metabolites of amixetrine in man and in the dog.

The urinary metabolites of N-(2-phenyl-2-isoamyloxy) ethyl-pyrrolidine-hydrochloride (amixetrine) studied in man and in the dog demonstrated a comparable mode of transformation of the drugs for both species. The principal metabolites of amixetrine isolated from urine and purified with the aid of chromatographic techniques were identified by IR, NMR and mass spectrometry. Untransformed amixetrine and (1,2-phenyl-1-hydroxy)ethylpyrrolidine were found in small quantities.

Pharmacological properties of 2-(2-chloro-p-toluidino)-2-imidazoline-nitrate (tolonidine), a new antihypertensive agent. II. Action on cardiac contraction, circulatory parameters, autonomic receptors and diuresis.

Tolonidine, 2(2-chloro-p-toluidino)-2-imidazoline-nitrate, is a substance chemically related to clonidine. In the anesthetized dog, tolonidine administered i.v.

Pharmacological properties of 2-(2-chloro-p-toluidino)-2-imidazoline-nitrate (Tolonidine), a new antihypertensive agent. I. Action on blood pressure and heart rate.

Tolonidine, 2-(2-chloro-p-toluidino)-2-imidazoline-nitrate, a substance structurally related to clonidine, was studied for its effects on blood pressure and heart rate in anesthetized or conscious, normotensive or hypertensive animals (mainly dogs). In all cases, blood pressure was lowered by tolonidine. Initial short-lasting hypertension was observed after each i.

Pharmacological properties of 2-(2-chloro-p-toluidino)-2-imidazoline-nitrate (tolonidine), a new antihypertensive agent. III. Action on the secretions of the digestive tract and on the central nervous system, acute toxicity.

The pharmacological properties of 2-(2-chloro-p-toluidino)-2-imidazoline-nitrate (tolonidine) a new synthetic derivative of imidazoline are reported in a series of three successive articles. This compound has been shown to possess hypotensive and antihypertensive properties. After i.
