Conditions for determination of: ketotifen hydrogen fumarate, azelastine hydrochloride, dimetindene maleate and promethazine hydrochloride by densitometric method in substances and pharmaceuticals were provided. Maximum wavelenghts were: 228 nm for ketotifen hydrogen fumarate, 295 nm for azelastine hydrochloride, 265 nm for dimetindene maleate and 255 nm for promethazine hydrochloride. The limi...

Several lines of evidence suggest that brain histamine may be involved in the central control of food intake. The effect of histamine on feeding is mediated through three kinds of receptors (H1, H2, and H3). The present study was designed to investigate the effect of intracerebroventricular injection of histamine, promethazine (H1 antagonist) and ranitidine (H2 antagonist) on food intake of fre...

Servicio de Dermatología, Hospital General Universitario de Valencia, Spain in 2004 and 2005.6 The highest number of positive reactions was seen with ketoprofen (45 cases). Promethazine occupied sixth place with 7 cases, although in none of them were the reactions considered relevant. In our experience, of the 48 photopatch tests done in the Dermatology Department of Hospital 12 de Octubre in M...

OBJECTIVE To compare the effects of promethazine with those of metoclopramide for hyperemesis gravidarum. METHODS Women at their first hospitalization for hyperemesis gravidarum were approached when intravenous antiemetic therapy was needed. They were randomly assigned to receive 25 mg promethazine or 10 mg metoclopramide every 8 hours for 24 hours in a double-blind study. Primary outcomes we...

background: postoperative nausea and vomiting is a high unpleasant symptom in surgical procedures. this study compares the effectiveness of midazolam with promethazine as multipurpose drug in postoperative nausea and vomiting as a preoperative and anesthetic medication after appendectomy. methods: this randomized, double – blind clinical trial study was performed in patients who underwent appen...

The objective of this study was to evaluate the physical and chemical stability of mixtures of undiluted palonosetron hydrochloride 50 micrograms/mL with undiluted metoclopramide hydrochloride 5 mg/mL and with promethazine hydrochloride 2 mg/mL diluted in 5% dextrose injection during simulated Y-site administration. Triplicate test samples were prepared by admixing 7.5 mL of palonosetron hydroc...

The ubiquitous use of pharmaceuticals has resulted in a continuous discharge into wastewater and pharmaceuticals and their metabolites are found in the environment. Due to their design towards specific drug targets, pharmaceuticals may be therapeutically active already at low environmental concentrations. Several human drug targets are evolutionary conserved in aquatic organisms, raising concer...

This study compared the sedative effectiveness of orally administered ketamine to a combination of oral meperidine/promethazine (Demerol/Phenergan) in two groups of children. One group received ketamine at a dose of 6 mg/kg and the other group received meperidine/promethazine combination at a dose of 2 mg/kg and 0.5 mg/kg, respectively. All children received nitrous oxide 30-50% titrated to eff...
