NCT03235401
To develop a patient-reported questionnaire to investigate the impact of PAH (pulmonary arterial hypertension) on patients' daily lives in terms of bothersomeness and disability.
NCT02692430
The purpose of this study is to perform a multicentre registry of cirrhotic patients who had been submitted to an imagining technique in recent years (angio-CT scan or abdominal MRI), in order to collect anatomical and clinical information. The main objective will be focused on the study of portosystemic shunts and their relation with portal hypertension. Patient with liver cirrhosis submitted to an abdominal angio-CT scan or a MRI from year 2010 to 2014 will be included in the study. The chosen imaging technique will be angio-CT preferably, but MRI data will also be available. Patients will be identified in every hospital by means of the registry of coded diagnoses and the lists of complementary tests performed. Clinical and radiological data of every patient will be collected. The clinical variables will be obtained from reviewing the patient clinical history. The radiological parameters will be gathered by means of the systematic review of the angio-CT or MRI.
NCT01648231
The purpose of this study is to evaluate the comparative bioavailability of two fixed dose combination tablet formulations of amlodipine and losartan in healthy volunteers. Subjects will receive each of the following three treatments administered in a randomized three-way crossover design: a reference treatment consisting of a 5mg amlodipine tablet and 100mg losartan tablet; a fixed dose combination tablet consisting of 5mg amlodipine and 100mg losartan; and another fixed dose combination tablet consisting of 5mg amlodipine and 100mg losartan; all three treatments will be administered once orally and in a fasted state. Serial blood samples will be obtained at pre-defined timepoints for pharmacokinetic analysis of amlodipine, losartan and carboxylic acid (this is the primary active losartan metabolite). Safety assessments will include measurements of orthostatic vital signs, electrocardiograms (ECG), collection of adverse events (AE) and clinical laboratory tests.
