Simultaneous determination of N-butylscopolamine and oxazepam in pharmaceutical formulations by first-order digital derivative spectrophotometry
(2005)
A simple method has been developed for the simultaneous determination of N-butylscopolamine bromide and oxazepam in pharmaceutical formulations using first-order digital derivative spectrophotometry. Acetonitrile was ...
Development of a Kinetic Spectrophotometric Method for the Determination of Ciclopirox Olamine in Pharmaceutical Sample
(Sociedad Chilena Química, 2016)
A simple and sensitive kinetic spectrophotometric method was developed for the determination of ciclopirox olamine in pharmaceutical formulations (cream). The method is based on the oxidation of ciclopirox olamine with ...
Withdrawal time of four pharmaceutical formulations of enrofloxacin in poultry according to different maximum residues limits
(2009)
To ensure delivery of safe animal products to consumers, the withdrawal time
(WDT) of drugs must be respected. Property differences among pharmaceutical
formulations, for the same drugs, can lead to differences in the ...
Synthesis and unusual swelling behavior of combined cationic/non-ionic hydrogels based on chitosan
(WILEY-V C H VERLAG GMBH, 2003-10-15)
Hydrogel-forming copolymers based on chitosan grafted with different amounts of polyacrylamide were synthesized and its swelling capacity determined in distilled water, sodium chloride solutions, as well as in buffer ...
Previous administration of naltrexone did not change synergism between paracetamol and tramadol in mice
(2012)
In the treatment of acute and chronic pain the most frequently used drugs are nonsteroidal anti-inflammatory drugs (NSAIDs), e.g., paracetamol; opioids, e.g., tramadol, and a group of drugs called coanalgesics or adjuvants ...
Synergism between NSAIDs in the orofacial formalin test in mice
(2009)
Opioids and non-steroidal anti-inflammatory drugs (NSAIDs) are used to relieve acute and chronic pain. The purpose of this study was to determine the degree of interaction between dexketoprofen and NSAID examples of COXs ...
Physicochemical characterization and cytotoxic studies of nonionic surfactant vesicles using sucrose esters as oral delivery systems
(Elsevier, 2014)
Several nanotechnological solutions for mucosal immunization have been proposed, such as nanoparticles, liposomes, solid lipidic particles, micelles, and surfactant vesicles. In recent years, surfactant vesicles have gained ...

(2013-07-09)
Objective: To determine the prescribing patterns for proton
pump inhibitors and to estimate the economic cost of their use
in a group of patients affiliated with the Colombian Health System.
Methods: This is a descriptive ...
Preliminary studies for ciclopirox olamine determination by thermal lens spectrophotometry
(Elsevier Inc., 2016)
© 2016 Elsevier B.V. The spectrophotometric kinetic methods are broadly used in the determination of drugs in several types of matrices. Thermal Lens Spectrometry (TLS) has demonstrated to be a sensitive indirect ...
