Study of protolytic equilibria of flurazepam
(The Analyst, 1990)
Protolytic equilibria of flurazepam, a diprotic base which is sparingly soluble in water, were investigated. The investigations were carried out in the pH range 0-12, at constant ionic strength (0.1 M NaCl) and 25 ± 0.1 ...
Electrochemical behavior and determination of quinolinium and isoquinolinium oximes
(Electroanalysis, 1991)
The electrochemical behavior of 1‐(2‐phenyl‐2‐hydroxyiminoethyl)‐1‐quinolinium chloride (F‐1) and 1‐(2‐phenyl‐2‐hydroxyiminoethyl)‐1‐isoquinolinium chloride (F‐2) was investigated using dc and differential pulse polarography ...
Determination of 1,3-bis(4-hydroxyiminomethylpyridinium)-propane dichloride (TMB-4) with Pd(II)
(Talanta, 1990)
The colour reaction of TMB-4 and palladium(II) chloride has been investigated. The optimum reaction conditions, spectral characteristics, stability constant and composition of the yellow water-soluble complex have been ...
A further study of the histamine-induced relaxations in the rat peripheral conduit arteries
(European Journal of Pharmacology, 1990)
Coulometric determination of some thiocompounds
(Farmaco, 1991)
Dependence of the Renal Excretion of Theophylline on its Plasma Concentrations and Urine Flow Rate in Asthmatic Children
(Journal of Pharmacy and Pharmacology, 1990)
Abstract— The dependence of the renal excretion of theophylline on its plasma concentration and urine flow rate has been investigated in asthmatic children of either sex. One group (age 12.25 ± 0.80, mean ± s.d. n = 8) was ...
Endothelium-independent contractions and relaxations of the rabbit large peripheral conduit arteries
(European Journal of Pharmacology, 1990)
Spectrophotometric investigation of metopropol-benzyl orange reaction and its application to the assay in pharmaceutical dosage forms
(Farmaco, 1995)
A sensitive spectrophotometric method for the determination of metoprolol tartrate in tablets and ampoules is presented. Using spectrophotometric measurements, it was found that metoprolol tartrate and benzyl orange form ...
Third-order derivative UV spectrophotometry and densitometry for the simultaneous assay of acetylsalicylic acid and salicylic acid in tablet formulations
(Societa Chimica Italiana, 1995)
Third-order derivative spectrophotometry is proposed for simultaneous determination of acetylsalicylic acid and free salicylic acid in sustained-release tablets, and compared with TLC-densitometry. Both methods were evaluated ...
Potentiometric investigation of the stability of palladium(II) complex of pralidoxime chloride in aqueous solution
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
The formation of a complex between palladium(II) chloride and pralidoxime chloride (PAM-2Cl) has been studied by means of potentiometric pH measurements. The real stability constant of the complex in aqueous medium of ionic ...
