Determination of 5-aminosalicylic acid in pharmaceutical formulations by square wave voltammetry at pencil graphite electrodes
(Sociedade Brasileira de Química, 2010-01-01)
An analytical method for the determination of the anti-inflammatory drug 5-aminosalicylic acid (5-ASA) in pharmaceutical formulations using square wave voltammetry at pencil graphite electrodes was developed. After the ...
Spectrophotometric determination of cefaclor in pharmaceutical preparations
(Sociedade Brasileira de Química, 1999-04-01)
A simple spectrophotometric method is proposed for the determination of cefaclor. The method involves alkaline hydrolysis of the drug in ammonia buffer solution at pH 10 to yield diketopiperazine-2,5-dione derivative and ...
Potentiometric determination of alendronate in pharmaceutical formulations
(Instytut Chemii Fizycznej Pan, 2004-01-01)
A simple, precise, fast and low-cost potentiometric method for alendronate determination in pharmaceutical formulations has been proposed. Alendronate present in tablets at the known concentration was potentiometrically ...
Coordination in Brazilian pharmaceutical supply chains
(FGV EAESP, 2014-12-26)
Supply chain coordination (SCC) can be a challenge for many organizations as different firms in the same chain has different expectations and interdependencies (Arshinder & Deshmukh, 2008). Lack of SCC can result in ...

Sequential injection analysis system with spectrophotometric detection for determination of norfloxacin and ciprofloxacin in pharmaceutical formulations
(Sociedade Brasileira de Química, 2011-01-01)
This work proposes a sequential injection analysis (SIA) system for the spectrophotometric determination of norfloxacin (NOR) and ciprofloxacin (CIP) in pharmaceutical formulations. The methodology was based on the reaction ...
Cathodic stripping voltammetric determination of cefaclor in pharmaceutical formulations
(Marcel Dekker Inc, 1999-01-01)
A sensitive method is described for the determination of cefaclor by cathodic stripping voltammetry at the hanging mercury drop electrode. cefaclor is accumulated at the electrode surface as a mercury salt, which is reduced ...
