Indirect Titrimetric and Spectrophotometric Methods for the Determination of Some Phenothiazine Psychotropics.

Titrimetric and Spectrophotometric Methods for the Determination of β-blockers in Pharmaceutical Dosage Form

Three new methods using titrimetric and spectrophotometry are described for the determination of Propranolol Hydrochloride (PPH) and Atenolol (AN) with potassium bromate as the oxidimetric reagent and acid dyes, Methyl orange and Indigo carmine. In direct titrimetric (method A), the drug is titrated directly with bromate in acid medium and in the presence of excess of bromide using methyl orang...

Titrimetric and Spectrophotometric Determination of Tinidazole Tablets

A simple, sensitive, rapid, reproducible, economical and easily accessible method for the determination of tinidazole tablets is described. From the experiment carried out there is the need for recrystallisation of tinidazole tablet before it is analysized. Ultraviolet (UV) absorption analysis corresponds to the result obtained with non-aqueous titration. And the best solvent to be use for non-...

Indirect spectrophotometric determination of some catecholamine drugs

Catecholamine drugs are aromatic vic-diols in which both the 3or 4-position is unsubstituted and these positions are not sterically blocked. Epinephrine(EP) or adrenaline(I) and norepinephrine(NE) or noradrenaline (II) are catecholamine drugs that are widely used in the treatment of allergic emergencies, status asthmatics, bronchial asthma, ventricular bradycardia, cardiac arrest, glaucoma, and...

Spectrophotometric and titrimetric methods for the determination of gentamycin and amoxycillin

This paper describes the Spectrophotometric and titrimetric methods for the determination of gentamycin and amoxycillin. The use of potassium iodate reagent for direct titrimetric method for the determination of some selected antibiotic has been described. The end point was characterized by a sharp change in color from colorless to deep red followed by spectrophotometric measurements.
