Two simple and sensitive indirect spectrophotometric methods for the assay of propranolol hydrochloride (PPH) and piroxicam (PX) in pure and pharmaceutical formulations have been proposed. The methods are based on the oxidation of PPH by a known excess of standard N-bromosuccinimide (NBS) and PX by ceric ammonium sulfate (CAS) in an acidic medium followed by the reaction of excess oxidant with ...

Spectrophotometric techniques were developed for the determination of single and binarymixture Promethazine hydrochloride (PMH) and Paracetamol (PCM). Normal and first derivative (D) used for single drug at λ 249.5 and 243.0 for PMH and 243.5 and 225 for PCM. The simultaneous determination of binary mixture (PMH) and (PCM) were accomplished by first derivative (D) and second derivative (D) spec...

Xylazine hydrochloride, α2 adrenoceptor agonist, is an analgesic, sedative, tranquilizer, and muscle relaxant agent in veterinary medicine which is mostly used as in pre-anesthesia in veterinary medicine. One of the main adverse effects of xylazine which limits application of this medication in small animal veterinary practice (mostly in cats) is nausea and vomiting which can end up with aspira...

We report 37-year-old man admitted to the psychiatric ward with acute depression. Antidepressive medications were initiated including: promethazine hydrochloride, hydroxyzine hydrochloride, lorazepam and haloperidol. In an attempt to control his depression, doctors increased the dose of haloperidol. Five days later he developed fever, cough, confusion and he was unable to eat. Accordingly, he w...

The ability of phenothiazine derivatives to inhibit the transport activity of P-glycoprotein in resistant mouse lymphoma and MDR/COLO 320 cells was studied. A rhodamine 123 efflux from the above-mentioned neoplastic cells in the presence of tested compounds was examined by flow cytometry. Two of the phenothiazine derivatives, namely perphenazine and prochlorperazine dimaleate, proved to be effe...

Promethazine (phenergan) has two methyl groups, which in these derivatives are associated with strong antihistaminic power, while chlorpromazine is a propylamine phenothiazine, which has more marked central nervous system effects but only one-hundredth of the antihistamine potency of promezathine. The Department of Pharmacology at Oxford has pointed out (Burns, 1948; Burns and Dutta, 1948; Dews...
