The use of analgesics in patients with arterial hypertension OBJECTIVES: To evaluate the use of analgesics in patients with arterial hypertension in primary healthcare and to determine the association with the level of hypertension control, comorbidities, and demographic indicators. To assess patients' knowledge of possible adverse drug interactions. STUDY DESIGN: Cross-sectional study STUDY PARTICIPANTS AND METHODS: The study included 100 adult patients being treated for arterial hypertension. The study participants were surveyed in person at a family medicine office using a questionnaire that included demographic data, information on hypertension, data on the frequency and type of analgesics they take, data on comorbidities, and data on knowledge of drug side effects and interactions. RESULTS: The study was conducted on 100 participants. A significant association was observed between the frequency of analgesic use and the average systolic and diastolic blood pressure values over the past month and on the day of data collection. Additionally, a significant association was noted between the average diastolic blood pressure value over the past month and the type of analgesic. Furthermore, a significant association was observed between the frequency of analgesic use and comorbidities. No significant association was found between the frequency of analgesic use and the demographic indicators of the participants. Seventy-two (72 %) participants were aware of drug side effects, and 56 (56 %) participants were aware of possible adverse drug interactions between analgesics and hypertension medications. CONCLUSION: The study showed that in patients with arterial hypertension, the frequency of analgesic use is significantly associated with the level of hypertension control and comorbidities, but not with demographic indicators. The participants were well-informed about the side effects of the medications they use, although there is still room for improvement in educating patients about possible adverse drug interactions.
