Filter by:Neuraxial anesthesia, which includes epidural anesthesia and intrathecal anesthesia, is a frequent anesthetic approach for caesarean delivery and other lower abdominal and lower limb anesthetic procedures. The addition of neuraxial morphine to local anesthetics provides an effective and prolonged postoperative analgesia. Neuraxial administration of morphine which is considered as a gold standard for analgesia has been associated with a frequent incidence of pruritus and postoperative nausea and vomiting. The incidence of neuraxial opioid induced pruritus varies widely from 30% - 60% after orthopedic surgery with intrathecal morphine injection and from 60% - 100% in pregnant women after neuraxial opioid administration. Parturients appear to be the most susceptible to neuraxial opioid-induced pruritus which probably might be due to the interaction of estrogens with opioid receptors. Although the exact mechanism of neuraxial opioid induced pruritus is unclear, the postulated mechanisms include the presence of an "itch center" in the central nervous system (CNS), medullary dorsal horn activation, antagonism of inhibitory transmitters, modulation of 5-hydroxytryptamine subtype 3 (5-HT3) or serotonergic pathways and the involvement of prostaglandins. There is dense concentration of opioid receptors and 5-HT3 receptors in the dorsal part of the spinal cord and the nucleus of the spinal tract of the trigeminal nerve in the medulla. Activation of these receptors by neuraxial opioid administration or by circulating estrogen in parturients results in neuraxial opioid induced pruritus which is usually localized to the face, neck, or upper thorax. Nalbuphine, propofol and ondansetron have been used effectively in the treatment of pruritus associated with neuraxial morphine in surgical patients. Granisetron is a potent and highly selective 5-HT3 receptor antagonist that has little or no affinity for other 5-HT receptors, or dopaminergic, adrenergic, benzodiazepine, histaminic, or opioid receptors. Its onset of action is 1-3 min, peak plasma level 30 min, plasma half-life is 4-6 h and duration of action up to 24 h. Its longer duration of action than that of ondansetron may coincide with the peak incidence of pruritus after intrathecal morphine (6-9 h). In contrast, other 5-HT3-receptor antagonists have affinities for various receptor-binding sites. For example, ondansetron has detectable binding to 5-HT1B, 5-HT1C, α1-adrenergic, and μ-opioid receptor sites. Although not proven, the binding of these agents to additional receptor subtypes other than their target receptor may underlie the inferior adverse event profile seen with ondansetron compared with granisetron.
The aim of the study is to evaluate the cosmetic features of the product WO 3308 by means of a questionnaire in an interview situation after two weeks of product treatment, giving special consideration to the cosmetic performance, efficacy and skin compatibility and with special focus on the reduction of pruritus. Additionally the tolerance will be evaluated by a dermatologist.
The purpose of this study is to determine the effectiveness of three doses of orvepitant, taken once a day, in the treatment of pruritus associated with atopic dermatitis.
This study aims to determine the effectiveness of using a commercially available acupuncture stud at the LI11 acupuncture point at reducing the severity of itch caused by intrathecal diamorphine in elective caesarean section.
A Phase 2 study evaluating safety, tolerability, and efficacy of SNA-120 ointment when administered topically with calcipotriene ointment for the treatment of pruritus and psoriasis.
This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of intravenous (IV) CR845 at a dose of 0.5 mcg/kg administered after each dialysis session. The study includes a 12-week Double-blind Phase and a 52-week Open-label Extension Phase.
Study of the efficacy, safety, and tolerability of serlopitant for the treatment of pruritus in adults with plaque psoriasis
The molecular mechanisms of action of photo(chemo)therapy in skin diseases are investigated in this study. The phototherapeutic modalities employed include UVB (ultraviolet B), UVA (ultraviolet A), PUVA (psoralen+UVA) and/or extracorporeal photochemotherapy (photopheresis). The study will address whether and how photo(chemo)therapy affects specific biologic pathways in different skin disorders and search for predictive biomarkers.
