Secondary metabolites from plants are a good source for the NSAID drug development. We studied the analgesic activity of ethanolic extract of Erythrina variegata L. (Fabaceae) followed by molecular docking analysis. The analgesic activity of Erythrina variegata L. is evaluated by various methods viz., acetic acid-induced writhing test, hot plate and tail immersion test. Subsequently, molecular ...

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...

Whereas acute stress often results in analgesia, chronic stress can trigger hyperalgesia/allodynia. This influence of long-term stress on nociception is relevant to numerous painful pathologies, such as fibromyalgia (FM), characterized by diffuse muscular pain (hyperalgesia) and/or tenderness (allodynia). Hence, there is a need for pre-clinical models integrating a chronic-stress dimension to t...

PURPOSE The present study was designed to investigate the anti-nociceptive activity of ethanolic leaf extract of Trema cannabina Lour (family: Cannabaceae) in experimental animal models. METHODS The anti-nociceptive action was carried out against two types of noxious stimuli, thermal (hot plate and tail immersion tests) and chemical (acetic acid-induced writhing) in mice. RESULTS Phytochemi...

Surfactants are frequently used to improve solubilization of lipophilic drugs. Cremophor EL (CrEL) is a polyoxyethylated castor oil surfactant used to solubilize water-insoluble drugs such as anesthetic, antineoplastic, immunosuppressive and analgesic drugs, vitamins and new synthetic compounds, including potential analgesics. The antinociceptive effect of CrEL (3.2, 6.4 and 10.6 g/kg, in 10 ml...

This study was aimed to investigate analgesic and neuropharmacological actions of the methanolic extract of rhizomes of Hedychium coronarium. The analgesic activity was evaluated for its central and peripheral pharmacological actions using tail immersion method and acetic acid-induced writhing test in mice respectively. The extract, at the doses of 100, 200 and 400 mg/kg body weight, produced a...

To elucidate the mechanism of anti-arthritic action of the Arthosansar, a polyherbal formulation has proven anti-arthritic activity. The mechanism is elucidated by emphasizing on immunomodulation, anti-inflammatory and analgesic action. The study is carried out using CFA induced arthritis in rats, carrageenan induced peritonitis in mice, inflammation induced by various phlogistic agents in rats...

Hydroxydihydrocarvone (HC) is a synthetic intermediate obtained by hydration of the natural compound (R)-(-)-carvone. The aim of the present study was to investigate the possible anti-inflammatory activity of orally administered HC. Toxicity, motor coordination, tail immersion test, as well as carrageenan-induced paw edema and myeloperoxidase (MPO) activity or peritonitis were all evaluated in ...

objective(s) the present study was undertaken to investigate the nociception activity of promethazine, a tranquillizer devoid of hypnotic activity in mice. materials and methods antinociception was evaluated, using the acetic acid-induced writhing, tail flick, hot plate and formalin pain tests. results promethazine (4 and 6 mg/kg) and acetylsalicylic acid (100 mg/kg) produced a significant inhi...

background and objective: considering the wide side effects of synthetic pain killers, use of herbal drugs in folk medicine as analgesic agents has increased. in the present work, we tried to uncover the pharmacological potential of ethanolic extracts by using various animal models and also to explore the potent antinociceptive effect of the plant thymus kotschyanus. materials and methods: the ...
