Pharmaceutical intervention in the rational use of intravenous omeprazole.

Objective: To describe the pharmaceutical interventions of a vertical clinical pharmacy service to promote the rational use of intravenous omeprazole.

Methods: A prospective and descriptive study carried out at a university hospital in the Midwestern Region of Brazil, from November 2014 to May 2015. The service consisted of the analysis of adequacy of the route of administration of omeprazole in relation to the clinical conditions of the patient, as well as the use of the appropriate diluent.

Potential drug-drug interactions in older adults: A population-based study.

Aim: To evaluate the potential drug-drug interactions (PDDI) between drugs used by older adults, any associated factors and recommended clinical management.

Methods: A cross-sectional, population-based study was carried out through a home survey of 934 older adults (from December 2009 to April 2010). A questionnaire was applied, and the participants were asked to show all the drugs used and their respective prescriptions, thus providing data to identify polypharmacy, self-medication and PDDI.

Medication adherence in patients in treatment for rheumatoid arthritis and systemic lupus erythematosus in a university hospital in Brazil.

Medication adherence is essential for the control of symptoms and progression of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). The aim of the study was to investigate medication adherence in outpatients in treatment for RA and SLE in a university hospital in Brazil. This was a quantitative, cross-sectional analytical study.

Medicine use by the elderly in Goiania, Midwestern Brazil.

Objective: To analyze the pattern of use of medications use in aged people and associate it with socioeconomic aspects and with the self-rated health.

Methods: A population-based cross-sectional design study with 934 elderly people from Goiania, Midwestern Brazil, between December 2009 and April 2010. Data were collected through a questionnaire.

A high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method using solid phase extraction for the simultaneous determination of plasma concentrations of enalapril and enalaprilate in hypertensive patients treated with different pharmaceutical formulations.

Unlabelled: Enalapril maleate, available on the market in a variety of different pharmaceutical formulations, is commonly used for the control of systemic arterial hypertension. Many therapeutical failures have been reported thus far in clinical practice with respect to switching between different pharmaceutical formulations of the same product during pharmacological therapy. In the present study, plasma concentrations of enalapril and enalaprilate were measured in hypertensive patients undergoing treatment with different pharmaceutical formulations.

Stability and in vitro release profile of enalapril maleate from different commercially available tablets: possible therapeutic implications.

Stability of enalapril maleate formulations can be affected when the product is exposed to higher temperature and humidity, with the formation of two main degradation products: enalaprilat and a diketopiperazine derivative. In this work, stability and drug release profiles of 20 mg enalapril maleate tablets (reference, generic and similar products) were evaluated. After 180 days of the accelerated stability testing, most products did not exhibit the specified amount of drug.
