Interactions Between Antihypertensive Drugs and Drugs Prescribed in the Emergency Room

Hypertension Clinical Trial

Official title: Pharmacological Interactions Between Antihypertensive Regimens and Drugs Prescribed in the Emergency Department of the HGZ 51

Status Completed

Clinical Trial Summary

Drug interactions (IFF) are events that occur when multiple drugs are administered at the same time to an individual. People with arterial hypertension generally require therapeutic regimens based on 2 or more drugs for their adequate control, which makes them patients with polypharmacy. When these patients require urgent medical attention, there is a risk that IFFs will occur between their base treatment and the drugs that are prescribed to solve the added condition.

Objective. To determine the frequency of pharmacological interactions between antihypertensive regimens and drugs used in the emergency service of Hospital General de Zona No 51 (HGZ 51).

Material and methods: Observational, descriptive, and prospective study. The participants will be eligible patients with systemic arterial hypertension treated in the emergency room of HGZ 51 in Gómez Palacio, Durango. Support systems will be used for clinical decision, to identify potential IFFs and to be able to classify them according to their mechanism (pharmacokinetics and pharmacodynamics) and severity. A descriptive statistical analysis will be carried out in the SPSS program using measures of frequency, dispersion and central tendency.

Clinical Trial Description

The researchers will invite individuals with high blood pressure who come to the emergency department in the period from January 2021 to December 2021 to participate in the study. They will be questioned about the selection criteria, and if they are eligible to be included in the study, they will be provided with the informed consent letter for reading, clarification of doubts and signature. Each participant will receive a copy of the informed consent letter.

Participants will be questioned directly to obtain information about their general data, medical history and about their drug treatment for hypertension. The rest of the data (admission diagnosis, drugs administered during their hospital stay, etc.) will be obtained from the clinical record, as well as the blood pressure measurements on admission, during their hospital stay and upon discharge. The analysis of the theoretical pharmacological interactions and their classification will be carried out prior to feeding the database using the IBM Micromedex Drug Interactions and iDoctus Clinical Decision Support Systems (CDSS).

The information obtained will be emptied into an Excel database for subsequent statistical analysis with the SPSS 21 program. The study information will remain confidential under the responsibility of the responsible researcher. As a protection measure on the information collected for the investigation, the personal identification data will be substituted by folio numbers. ;
