BACKGROUND Bupropion hydrochloride is used frequently in the treatment of depression and in smoking cessation therapy. METHODS We report a case of bupropion hydrochloride induced serum sickness-like reaction. RESULTS There was complete resolution of symptoms on discontinuing bupropion and instituting therapy with prednisone and antihistamines. CONCLUSION This case is seemingly the first r...

In  the  current  study,  a  new  technique  was  developed  for  quantification  and  qualification  of pseudoephedrine hydrochloride (PSE) in a real sample, which was based on electrochemical sensors and  molecular  imprinted  polymer  (MIP).  The  carbon  paste  electrode  (CPE)  was  modified  and optimized by a different ratio of MIP. MIP/CPE was used as the extraction and working electrod...

Penehyclidine hydrochloride can promote microcirculation and reduce vascular permeability. However, the role of penehyclidine hydrochloride in cerebral ischemia-reperfusion injury remains unclear. In this study, in vivo middle cerebral artery occlusion models were established in experimental rats, and penehyclidine hydrochloride pretreatment was given via intravenous injection prior to model es...

The z-average molecular weight of horse liver alcohol dehydrogenase in dilute neutral buffer is 78,200 by sedimentation equilibrium. Guanidine hydrochloride, 1 M, reversibly inhibits enzymatic activity. The inhibition with nicotinamide adenine dinucleotide is competitive and with ethanol is mixed. When ethylenediaminetetraacetate is added to the enzyme in 1 M guanidine hydrochloride, zinc is re...

Ethylone, a synthetic cathinone with psychoactive properties, is a designer drug which has appeared on the recreational drug market in recent years. Since 2012, illicit shipments of ethylone hydrochloride have been intercepted with increasing frequency at the Canadian border. Analysis has revealed that ethylone hydrochloride exists as two distinct polymorphs. In addition, several minor impuriti...

Objective: This study aims to decompose antibiotic of tetracycline hydrochloride (TCH) in aqueous medium by photocatalysis under the visible light irradiation. Method: Photocatalyst e -Zn(OH)2 was synthesized facile precipitation method from an containing zinc nitrate, using trisodium citrate dihydrate. The characterization as-prepared material confirmed XRD, SEM, FI-IR, and UV-Vis-DR. catalyti...

DESCRIPTION TALWIN Nx (pentazocine and naloxone hydrochlorides, USP) contains pentazocine hydrochloride, USP, equivalent to 50 mg base and is a member of the benzazocine series (also known as the benzomorphan series), and naloxone hydrochloride, USP, equivalent to 0.5 mg base. TALWIN Nx is an analgesic for oral administration. Chemically, pentazocine hydrochloride is (2R*,6R*,11R*)-1,2, 3, 4, 5...

The reversible denaturation of protein disulfide isomerase proceeds through intermediates that are stabilized by interaction with guanidine hydrochloride. At pH 7.5, the equilibrium denaturation by urea is completely reversible and the transition can be reasonably well-described by a two-state model involving only native and denatured forms. In comparison, the equilibrium denaturation by guanid...
