The present study evaluates the central and peripheral analgesic activity of ethanolic extract of Cananga Odorata Lam [EECO] in experimental animals.Acute toxicity test was done following OECD guidelines. EECO (100mg/kg, 200mg/kg and 400mg/kg b.w. p.o) was evaluated for central and peripheral analgesic activity by the Tail flick method in wistar rats and 0.7%acetic acid induced Writhing test in...

phencyclidine (1-(1-phenylcyclohexyl) piperidine, pcp, i) and ketamine (2-o-chlorophenyl-2-methylaminocyclohexan, ii) have shown analgesic effects. some of its derivatives were synthesized and their biological properties have been studied. in this study, a new derivative of pcp, (1-[1-(3-methoxyphenyl) (tetralyl)] piperidine, pcp-och3-tetralyl, iii) was synthesized and the acute thermal pain of...

objective: vitex agnus-castus (vac) and its essential oil have been traditionally used to treat many conditions and symptoms such as premenstrual problems, mastalgia, inflammation, sexual dysfunction, and pain. in this study, the effects of essential oil extracted from vitex agnus-castus (eovac) leaves were investigated in three behavioral models of nociception in adult male wistar rats. materi...

Pain represents a major clinical problem and one which has exercised generations of healthcare professionals. Earthworms are used as a traditional Chinese medicine, and have been applied pharmacologically and clinically since a long time in China. However, the analgesic effects of earthworm extract (EE) are seldom studied. Hence, we evaluated the analgesic effects of EE in mice. The obtained da...

The sedative and analgesic potential of Urena sinuata L. was investigated for the first time in this study. The crude methanol extract of Urena sinuata L. leaves was evaluated for its central nervous system (CNS) depressant effect using rodent behavioral models. Methanol extract of Urena sinuata at a dose of 400 mg/kg body weight, displayed a suppressive effect on motor activity, exploratory be...

In folk medicine, Polyalthia suberosa is used as abortifacient, laxative, febrifuge analgesic, filler of tooth cavities, and anti-HIV drug and for rheumatism and various skin infections. The present study was directed to evaluate the analgesic and anti-inflammatory activities of diethyl ether and n-hexane extracts of Polyalthia suberosa leaves (PSDE and PSNH). A variety of tests including forma...

The hyperalgesic properties of the emetic drug lithium chloride (LiCl) were examined in eight experiments. At a dose of 63.6 mg/kg, LiCl produced hyperalgesia in the radiant-heat (Experiment la) and immersion (Experiment 1b) tail-flick tests. At doses of 15.9, 31.8, 63.6, and 127.2 mg/kg, LiCl failed to produce hyperalgesia during the delayed behavioral response in the formalin test (Experiment...

Opioid analgesics with restricted access to the central nervous system represent a new approach to the treatment of severe pain with an improved safety profile. The objective of this study was to investigate the peripheral and central components of the antinociceptive actions of the 6-amino acid conjugates (glycine, alanine, and phenylalanine) of 14-O-methyloxymorphone. Their antinociceptive ac...

Purpose: Buprederm-Buprenorphine transdermal delivery system (BTDS) was developed for the treatment of post-operative and chronic pains. This study examined the relationship between the plasma concentration of buprenorphine and its analgesic effect (tail flick test) in order to assess the usefulness of pharmacokinetic-pharmacodynamic (PK-PD) modeling in describing this relationship. Methods: Af...
