Determination of Analgesics (Dipyrone and Acetaminophen) in Pharmaceutical Preparations by Cyclic Voltammetry at a Copper(II) Hexacyanoferrate(III) Modified Carbon Paste Electrode
(Bentham Science Publ Ltd, 2009-10-01)
Copper(II) hexacyanoferrate(III) (CuHCF) modified carbon paste electrode was used for the electroanalytical determination of dipyrone and acetaminophen in pharmaceutical preparations by cyclic voltammetry. Several parameters ...
Flow-injection spectrophotometric determination of methyldopa in pharmaceutical formulations
(Elsevier B.V., 2005-07-15)
A flow-injection spectrophotometric procedure is proposed for methyldopa determination in pharmaceutical preparations. The determination is based on formation of a yellow product (measured at 410 nm) after complexation of ...

One-pot biocatalyzed preparation of substituted amides as intermediates of pharmaceuticals
(Elsevier Science, 2001-01)
A lipase-catalyzed procedure is described for the one-pot conversion of carboxylic acids into substituted amides via in-situ formation of the ethyl ester and subsequent aminolysis. The procedure was optimized for the ...
Analysis of extemporaneous oral liquid from commercially available drugs in hospital
(2016-07-01)
The objective of this study was to identify drugs that received dose adjustments (DA) and pharmaceutical alternatives (PA) that avoid DA, and calculate the economic percentage of this replacement. A descriptive, observational ...
