O controlo de qualidade é responsável pela análise e controlo dos fármacos, cosméticos e dispositivos médicos desde o início da sua produção, com a análise da matéria-prima, até ao produto acabado, com a verificação das condições de embalamento e armazenamento. A execução do controlo de qualidade por parte das indústrias farmacêuticas revela-se importante para que a qualidade, segurança, eficácia e credibilidad...
Os Inibidores da Bomba de Protões são fármacos que inibem a produção de ácido gástrico, por inibição da ATPase H+/ K+ das células parietais do estômago. Os Inibidores da Bomba de Protões são para ser utilizados durante o menor intervalo de tempo possível e na dose mínima eficaz, devendo-se recorrer a uma reavaliação periódica da necessidade de tratamento. Apesar destes pressupostos para a sua utilização, existe...
During compound screening and drug development, long-term oral drug administration to experimental rodents is often required. Oral gavage, a straightforward drug dosing technique, is not suitable for extended treatments considering the recurrent traumatic complications (gastroesophageal injury) and physiological distress (corticosterone levels alterations) that frequently bias experimental design outcomes. Thes...
Fluoxetine is the most prescribed drug for treatment of depression. Recently, its presence in aquatic environment has been receiving a growing interest as several studies assessed its effects on aquatic fauna. Therefore, it's important to have an analytical method capable of monitoring these compounds at low concentrations. In this study, a new method was developed based on dispersive liquid–liquid microextract...
Objective: This paper describes the development and validation of two UV-Visible spectrophotometric analysis methods, using absolute ethanol (method A) and HCl 0.1 M (method B) as solvents, to quantify fluoxetine (FLX) in its generic and brand name form. The objective is to validate both methods and compare the concentrations of the samples obtained from each one. Methods: Validation of each method with the det...
Molecular imaging tools such as Positron Emission Tomography (PET) are increasingly being used in the drug development process. The unrivaled sensitivity of PET coupled with a solid experience in developing highly targeted molecular probes makes this technique a very valuable tool at all stages from pre-clinical development to the clinical phases. Positron emitting tracers allow us to measure, quantitatively, m...
