BACKGROUND Itch is one of the most frequent skin complaints and its treatment is challenging. From a neurophysiological perspective, two distinct peripheral and spinothalamic pathways have been described for itch transmission: a histaminergic pathway and a nonhistaminergic pathway mediated by protease-activated receptors (PAR)2 and 4. The nonhistaminergic itch pathway can be activated exogenous...

This study investigated antipruritic and anti-inflammatory effect of Centella asiatica extract in rats and anti-allergic in vitro using sheep (Capra hircus) serum method and compound 48/80 induced mast cell degranulation method, compared with standard drug ketotifen fumarate. In rats, extract of Centella asiatica administered orally was examined for anti-pruritic study and chlorpheniramine male...

In the present study, the effect of aqueous extract of Momordica dioica, aqueous extract of Myrica esculenta and ethanolic extract of Euphorbia hirta a lone and in combinat ion on h istamine induced bronchospasm in guinea p ig, milk induced leukocytosis and eosinophilia in mice and on antipruritic activity in mice was done. In the animal model o f h istamine induced bronchospasm , all plant sho...

Phosphodiesterase (PDE) 4 inhibition is a well-known anti-inflammatory mechanism, but the development of PDE4 inhibitors has been hampered by side effects such as nausea and emesis. Local delivery of a PDE4 inhibitor to the site of inflammation may overcome these issues. The purpose of this study was to assess the therapeutic potential of E6005 (methyl 4-[({3-[6,7-dimethoxy-2-(methylamino)quina...

BACKGROUND Butorphanol is an opioid analgesic with partial agonist actions at micro- and kappa-opioid receptors (MOR and KOR). Previous studies have demonstrated that both MOR antagonists and KOR agonists are effective in alleviating intrathecal morphine-induced itch in primates. The aim of the study was to investigate the effectiveness of butorphanol as an antipruritic and to elucidate the rec...

Astemizole and terfenadine, two potent non-sedative H1 antihistamines, had no effect on itch measured objectively as nocturnal scratching and subjectively on a 10 cm line. Trimeprazine, however, a more sedative but less potent H1 antihistamine, was antipruritic, as was nitrazepam, a sedative benzodiazepine. We concluded (a) that antipruritic drugs act centrally by a property related to sedation...
