Analysis of Potential Drugs Interaction on Antihypertension Drugs Prescription in Community Health Center of Sukmajaya District in Period of June-November 2015

Abstract

Objectives: Hypertension is a common disease around the world. Depending on the severity or the presence of other diseases, whether related or unrelated, additional drug therapy may be required to optimize treatment and to reduce the side effects of drugs. The use of drugs in large amounts may increase the risk of drug interactions. The purpose of this research was to evaluate the characteristics of hypertension patients, prescriptions, and potential drug interactions in hypertensive patients in the Sukmajaya Community Health Center from June to November 2015.Methods: This research used a descriptive analytic method and the data were retrospectively obtained. Results:The results were based on the analysis of 350 prescriptions of female (67.43%) and male (32.57%) patients, with the highest prevalence of hypertension occurring at the age of ≥55 years. Potential drug interactions were analyzed using Micromedex. The most frequent potential interaction resulted from the combined use of captopril and non-steroidal anti-inflammatory drugs. The most frequent mechanism of drug interaction was pharmacokinetics (51.06%). The chi-square test results showed a significant relationship between the number of prescribed drugs and potential interactions at a probability value of 0.0001 and an odds ratio of 5.940 (15.588-2.263). Conclusions:With respect to interaction mechanism, pharmacokinetic (51.06%) was the most frequent and 61.70% of potential cases involved a moderate interaction risk.

Drug-related problems in hypertensive patients: A cross-sectional study from Indonesia

“…This interaction can cause serious heart disease, such as ventricular arrhythmias and sudden cardiac death, which has been shown by cohort studies that found a link between serious ventricular arrhythmias and sudden cardiac death in the use of domperidone at dosages >30 mg/day in patients >60 years old. [ 14 ] To avoid this interaction, the lowest dosage and short duration of domperidone are recommended. If the patient experiences fainting, dizziness, palpitation, and seizures after receiving domperidone, it must be stopped.…”

Identification of Drug-Related Problems in Patients With Upper Acute Respiratory Tract Infections in Tebet Subdistrict Health Center

“…Drug replacement is done by replacing the antibiotic with commonly given antibiotics such as amoxicillin or eliminating the use of anti-inflammatory drugs in patients during erythromycin use. In addition, health facilities should also file or collect data on interactions that occur as well as routine monitoring of all types of interactions [1,33].…”

The Clinical Significance of Potential Drug-Drug Interactions and Their Targets for Minimization Among Hypertensive Diabetic Outpatients at a Kenyan Referral Hospital

“…In an attempt to normalize the blood pressure and glucose levels, multiple drugs may predispose the patient to polypharmacy [9] and have the potential to interact, thereby producing undesirable effects [10]. Studies have also indicated that about 60% of patients may have drug interactions that will cause undesirable outcomes.…”
