2. UTILIZAÇÃO DO ESPECTRÔMETRO DE ABSORÇÃO ATÔMICA PARA DETERMINAÇÃO DE CLORIDRATO DE METFORMINA E CLORIDRATO DE RANITIDINA EM MEDICAMENTOS
The utilization of atomic absorption spectrometer for metformin (MET) and ranitidine (RAN) chlorohydrates determination in medicines is proposed. The spectral lines of nickel and aluminum at 232.0 and 308.2 nm were selected for MET and RAN absorbance monitoring, respectively. The results were compared to those obtained by molecular absorption spectrometry at

3. CHARACTERIZATION OF ENALAPRIL AND RANITIDINE CHLORINATION BY-PRODUCTS BY LIQUID CHROMATOGRAPHY/HIGH-RESOLUTION MASS SPECTROMETRY AND THEIR TOXICITY EVALUATION
Due to its low cost, its capability for disinfection and oxidation, chlorination using gaseous chlorine or hypochlorite salts, has also been commonly applied in water treatment plants for oxidation and disinfection purposes. Little is known about the identity and toxicity of by-products resulting from the chlorination of pharmaceutical micropollutants, such

4. Test of dissolution and comparison of in vitro dissolution profiles of coated ranitidine tablets marketed in Bahia, Brazil
A ranitidina é um fármaco antissecretor, antagonista H2, usado no tratamento de desordens gástricas e duodenais. O teste de dissolução é utilizado para obter e comparar perfis de dissolução, estabelecendo semelhança de formas farmacêuticas. Este estudo tem por objetivo comparar perfis de dissolução de comprimidos revestidos contendo 150 mg de ran

5. Effect of histamine H1 and H2 receptor antagonists, microinjected into cerebellar vermis, on emotional memory consolidation in mice
This study investigated the effects of histamine H1 or H2 receptor antagonists on emotional memory consolidation in mice submitted to the elevated plus maze (EPM). The cerebellar vermis of male mice (Swiss albino) was implanted using a cannula guide. Three days after recovery, behavioral tests were performed in the EPM on 2 consecutive days (T1 and T2). Imme

6. A participação de diferentes sistemas neuromodulatórios no hipocampo, núcleo basolateral da amígdala e córtex pré-frontal ventromedial na extinção de memórias aversivas
Extinction consists of the learned inhibition of retrieval of previously acquired memory. Many forms of learning are modulated by ¿-noradrenergic, D1-dopaminergic and H2-histaminergic receptors on ventromedial prefrontal cortex (vmPFC), basolateral amygdala (BLA) and dorsal hippocampus. Therefore, the aim of this work was investigated the modulation of aver

7. Anti-oxidative and anti-ulcerogenic activity of Ipomoea imperati
Ipomoea imperati (Vahl) Griseb., Convolvulaceae, is used in traditional medicine for the treatment of inflammation, swelling and wounds, as well as to treat pains and stomach problems. This work evaluates the anti-oxidative activity by ESR (Electron Spin Resonance spectroscopy) and the preventive and curative actions of I. imperati in gastric ulcer animal mo

8. Simultaneous determination of moxifloxacin and H2 receptor antagonist in pharmaceutical dosage formulations by RP-HPLC: application to in vitro drug interactions
Simultaneous determination of moxifloxacin (MOX) and H2-antagonists was first time developed in bulk and formulations. Purospher STAR C18 (250 x 4.6 mm, 5 μm) column was used. The mobile phase (methanol: water: ACN, 60:45:5 v/v/v, pH 2.7) was delivered at a flow rate of 1.0 mL min-1, eluent was monitored at 236, 270 and 310 nm for cimetidine, famotidine and

10. New reagents for the spectrophotometric determination of ranitidine hydrochloride
A new spectrophotometric method is proposed for the assay of ranitidine hydrochloride (RNH) in bulk drug and in its dosage forms using ceric ammonium sulphate (CAS) and two dyes, malachite (MAG) green and crystal violet (CV) as reagents. The method involves the addition of a known excess of ceric ammonium sulphate to ranitidine hydrochloride in acid medium,

11. Influencia da ranitidina e pantoprazol no pH gastrico em pacientes septicos / Ranitidine is unable to maintain gastric pH level above 4 in septic patients
Objetivo: Avaliar a capacidade da ranitidina e do pantoprazol em elevar e manter o pH gástrico = 4 em pacientes sépticos. Material e métodos: Foram estudados 20 pacientes internados na UTI, com diagnóstico de sepse/choque séptico, em ventilação mecânica. Dez receberam ranitidina (50 mg em bolo 8/8 horas) e outros 10 pacientes receberam pantoprazol 40

12. Estudo da degradação de ranitidina via H2O2 eletrogerado/Fenton em um reator eletroquímico com eletrodos de difusão gasosa
The study of the electrochemical degradation of the ranitidine was developed using an electrochemical reactor with a gas diffusion electrode (GDE) as cathode. The electrolysis experiments was performed at constant current (1 < A < 10) and flow rate of 200 L h-1. The process of drug degradation, chemical/electrochemical and electro-Fenton ways, using electroc
