Study of heterogeneous equilibria in saturated aqueous solutions of some 7-chloro-1,4-benzodiazepines
(The Analyst, 1990)
Acid-base equilibria in heterogeneous and homogeneous systems of some sparingly soluble benzodiazepines (diazepam, prazepam, chlordiazepoxide and medazepam) were investigated in aqueous solution and the corresponding ...
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 ...
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)
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)
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 ...
Potentiometric and volumetric determination of 6-mercaptopurine
(Springer-Verlag, 1990)
Three methods for the determination of 6-mercaptopurine in the pure state and in tablets are described. One method is based on the reaction of this compound with silver ions, whereby an equivalent amount of nitric acid is ...
Coulometric determination of levodopa, methyldopa and carbidopa
(Farmaco, 1990)
Spectrophotometric determination of tilidine using bromocresol green and bromophenol blue
(Acta Pharmaceutica Hungarica, 1990)
