Sir,?In reply to Capt. T. D. W. Gillespie's inquiry in the Novtmber issue of the I. M. Q. as to the quantity of quinine urea hydrochloride to be injected hypodermically to produce local anaesthesia, I may say as follows: In the New York Medical Journal (1915, II, 708) Amster recommends quin-urea hydro as a local anaesthetic. He has performed 200 severe operations with a freshly prepared solutio...

Young albino rats (120-190 g) were divided in 4 groups (6 animals per group). One group was injected with clonidine hydrochloride (100 ",g/kg. ip); another group received equivalent volume of normal saline only. The third group also received clonidine but was given phenoxybenzamine hydrochloride (10 mg/kg. ip) 1 hr before clonidine Injection. The fourth group received phenoxybenzamine hydrochlo...

BACKGROUND AND THE PURPOSE OF THE STUDY The binding ability of a drug to serum albumin has influence on the pharmacokinetics of a drug. In the present study, the mutual interaction of anticancer drug erlotinib hydrochloride with bovine serum albumin (BSA) using fluorescence and UV/vis spectroscopy was investigated. METHODS The BSA solution (0.1 mM) was prepared daily in Tris buffer (0.05 mol ...

Major uses Thioridazine hydrochloride (further thioridazine) is a representative of phenothiazine compounds, and it is an antipsychotic drug (synthesized in 1959). It relieves tension and anxiety, and acts against multiple symptoms, e.g. agitation, depression, behavior problems and sleep disturbances. Thioridazine is also effective in controlling the symptoms of schizophrenia, mania, and other ...

HYPOTHESIS Intravenous patient-controlled analgesia (IV PCA) meperidine hydrochloride can be used with a reasonable margin of safety. DESIGN A retrospective review was performed of 355 medical records of patients receiving IV PCA meperidine treatment. Four groups of patients were defined, based on daily meperidine dose and the presence or absence of central nervous system excitation adverse e...

Clonidine hydrochloride is an antihypertensive agent used for migraine prophylaxis, attention deficit hyperactivity disorder, menopausal flushing and Tourette syndrome. The quantity of the active substance in pharmaceutical preparations must be within specific limits, in agreement with the respective label claim. Therefore, the aim of this study was to establish the conditions for two spectroph...

UV-visible and Fluorescence spectroscopic methods were employed to study the interaction of human serum albumin (HSA) with Valacyclovir Hydrochloride. Additionally, molecular dynamics and molecular docking simulations were used to visualize and specify the binding site of Valacyclovir Hydrochloride. The Stern-Volmer and van't Hoff equations along with spectroscopic observations, were used to de...

The inhibitory effects of three topical anesthetics of various concentrations on the growth of Pullularia pullulans, Debaryomyces hansenii, and on pigment production by P. pullulans were investigated. The topical anesthetics were benoxinate hydrochloride, proparacaine hydrochloride, and tetracaine hydrochloride. In decreasing order, the inhibiting effects of the drugs on growth were benoxinate,...
