Aims: The purity of street cocaine preparations, which are incorporated by a drug consumer, may differ considerably. Cocaine may be adulterated with a various number of pharmacologically active compounds, such as lidocaine or levamisole. Adverse side effects or lethal complications may occur if cocaine is found to contain these substances (adulterants). We examined lung tissue und blood for som...

Two simple, rapid, cost-effective and sensitive spectrophotometric procedures are proposed for the determination of hydroxyzine dihydrochloride (HDH) in pharmaceuticals and in spiked human urine. The methods are based on the charge transfer complexation reaction of the drug with either iodine (I2) as a σ-acceptor (method A) in dichloromethane or picric acid (PA) as a π-acceptor (method B) in ch...

Materials and methods Our research took place in a private psychiatric clinic (2005-2009) and focused on the effectiveness of a certain pharmacological combination administered to a sample of 37 patients, in an attempt to control the alcohol withdrawal syndrome. The pharmacological combination comprised 30mg-60mg Chlordiazepoxide hydrochloride, 300mg-500mg Triapride hydrochloride, 300mg-500mg H...

The objective of the study was to formulate a modified proniosomal gel (HMPG) of hydroxyzine hydrochloride. HMPG formulations were prepared by coacervation phase separation technique with different combination of non-ionic surfactants (Tweens and Spans) with phospholipids such as phospholipon 80H and 90H. Taguchi design of experiments was used to optimize the various formulation variables. The ...

BACKGROUND Deep sedation or general anesthesia is generally used during atrial fibrillation (AF) ablation. The aim of this study was to report the safety and feasibility of minimal sedation during AF ablation. METHODS AND RESULTS One thousand and fifty-two AF ablation procedures in 819 patients (62 ± 11 years, 621 men, 506 paroxysmal) were included. Boluses of intravenous hydroxyzine pamoate ...

PURPOSE The purpose of this study was to evaluate the cardiopulmonary effects of 2 sedation regimens during treatment: (1) oral meperidine and hydroxyzine with nitrous oxide (N2O); and (2) oral diazepam and hydroxyzine, submucosal meperidine, and N2O. Nitrous oxide was tapered to oxygen (O2) only 10 minutes following submucosal meperidine administration. METHODS Sixty-two children were evalua...

Fixed drug eruption is an uncommon adverse drug reaction caused by delayed cell-mediated hypersensitivity. Levocetirizine is an active (R)-enatiomer of cetirizine and there have been a few reports of fixed drug eruption related to these antihistamines. We experienced a case of levocetirizine-induced fixed drug eruption and cross-reaction with other piperazine derivatives confirmed by patch test...
