Simultaneous determination of lignocaine hydrochloride and phenylephrine hydrochloride by HPTLC
Journal of Pharmaceutical and Biomedical Analysis, 2000A high performance thin layer chromatographic (HPTLC) method for the simultaneous quantification of lignocaine hydrochloride (LIG) and phenylephrine hydrochloride (PHE) is described. The mobile phase consisted of ethyl acetate-methanol ammonia (4:1:0.4 v/v/v).

GLC Determination of Phenylephrine Hydrochloride in Human Plasma
Journal of Pharmaceutical Sciences, 1973A sensitive GLC method for the determination of phenylephrine in human plasma is described. Its application to in vivo phenylephrine levels in humans is currently being investigated. In the procedure, plasma components that interfere with the assay were removed using ion-exchange chromatography.

Stability of phenylephrine hydrochloride injection in polypropylene syringes
American Journal of Health-System Pharmacy, 2007The stability of extemporaneously prepared phenylephrine hydrochloride injection stored in polypropylene syringes was studied.Dilution of phenylephrine hydrochloride to a nominal concentration of 100 mug/mL was performed under aseptic conditions by adding 100 mg of phenylephrine hydrochloride (total of 10 mL from two 5-mL 10-mg/mL vials) to 1000 mL of ...

Journal of Pharmaceutical Sciences, 1974
A column chromatographic procedure was developed for separating acetaminophen, phenylephrine hydrochloride, and diphenhydramine hydrochloride in combination with ascorbic acid. While acetaminophen, which passes through an alginic acid column with the washings, is determined spectrophotometrically at 257 nm, phenylephrine hydrochloride and ...

, 2021 The Spectrophotometric Determination of Tetracaine and Phenylephrine Hydrochloride
Journal of the American Pharmaceutical Association (Scientific ed.), 1952A method is presented for the quantitative determination of tetracaine and phenylephrine hydrochloride in therapeutic preparations based on ultraviolet spectrophotometry and colorimetry. Tetracaine absorbs light strongly in the spectral region of 310 mμ, while phenylephrine shows negligible absorption at this wave length.

Analysis of Phenylephrine and Phenylpropanolamine Hydrochlorides in Combination
Journal of Pharmaceutical Sciences, 1971An accurate and precise method for determination of phenylephrine hydrochloride and phenylpropanolamine hydrochloride is described. This method is based on measuring the aryl aldehydes, which are selectively extracted after periodate oxidation of the two phenylethanolamines. It is sufficiently sensitive for individual dosage unit measurements. No assay

PHENYLEPHRINE HYDROCHLORIDE IN PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA
Journal of the American Medical Association, 1955Phenylephrine (Neo-Synephrine) hydrochloride was first suggested as an effective drug in the treatment of paroxysmal supraventricular tachycardia by Youmans and his group in 1947. Since this time others have mentioned its use and at the same time suggested that the drug was relatively innocuous in the absence of heart disease.

Effect of Phenylephrine Hydrochloride on Conjunctival Po2
Archives of Ophthalmology, 1984Phenylephrine hydrochloride eyedrops induce vasoconstriction through alpha-adrenergic mechanisms. Ten subjects underwent a 46% reduction in conjunctival PO2 when 2.5% phenylephrine eyedrops were administered. Compared with a control group, this reduction was significant. The induced conjunctival hypoxia lasted about 80 minutes. These findings suggest a
