RESUMO
The study aimed to analyse the adverse drug reactions report form data received by the State Expert Center of the Ministry of Health of Ukraine from healthcare professionals in the Lviv region in 2022. Regarding specific types of medicines, the ones with proven cause-and-effect relationships that caused the highest frequency of adverse drug reactions incidents were chemotherapeutic agents (35.5%), medicines affecting the cardiovascular system (20.3%), and non-steroidal anti-inflammatory drugs (8%). Within the penicillin class, amoxicillin potentiated by clavulanate (67%) and amoxicillin (29%) were the dominant drugs showing the highest incidence rate of adverse reactions. Among cephalosporins, ceftriaxone (46%) and cefixime (15%) were found to take the lead in terms of adverse reaction frequency. The highest proportion among all adverse drug reactions caused by penicillins and cephalosporins was attributed to allergic reactions. To confirm or rule out immediate or delayed type allergies in patients, as well as in patients with a history of immediate-type allergic reactions to ß-lactams and planned administration of another ß-lactam, it is necessary to conduct skin testing (skin prick test, or, in the case of parenteral administration, intradermal test) with the planned ß-lactam antibiotic. The second highest proportion of induced adverse drug reactions was attributed to drugs affecting the cardiovascular system (20.3%). The leading medications in the angiotensin-converting enzyme inhibitors category were enalapril (47%) and the combination of lisinopril with hydrochlorothiazide (24%). In the angiotensin II receptor blockers category of medications, valsartan (30%) and telmisartan-hydrochlorothiazide combination (20%) ranked highest. In the category of CCB drugs, amlodipine (66%) and nifedipine (20%) held the leading positions. among angiotensin-converting enzyme inhibitors, enalapril caused the most prevalent and predicted adverse reaction, that of cough, affecting 10.5% of patients, whereas, with the combination therapy of lisinopril and hydrochlorothiazide, the cough was observed in only 5.2% of patients. Angiotensin II receptor blockers have a better safety profile, particularly concerning cough. Analysis of adverse drug reactions reports for angiotensin II receptor blockers showed no cases of cough with valsartan and telmisartan-hydrochlorothiazide combination. Among calcium channel blocker medications, amlodipine emerged to rank highest, causing one of the predicted adverse drug reactions, that of lower extremity oedema in 64% of patients. The second position was taken by the combination of amlodipine with valsartan, which showed a statistically significant reduction of 14.3% (p≤0.05) in the incidence of oedema. Using amlodipine at a dose of 5 mg in combination with sartan medicines as angiotensin receptor blockers is an effective therapeutic alternative not only for enhancing blood pressure control in hypertensive patients but also for improving the safety profile of amlodipine. Among all the non-steroidal anti-inflammatory drugs prescribed to patients in the Lviv region in 2022, the highest number of adverse reactions was associated with the administration of diclofenac, ibuprofen, paracetamol, and nimesulide, causing adverse drug reactions in 22%, 19%, 17%, and 10% of cases, respectively. The most common systemic manifestations of adverse reactions with these non-steroidal anti-inflammatory drugs were allergic reactions (63.4%) and gastrointestinal disorders (26.8%). From an evidence-based medicine perspective, the most justified approach for primary and secondary prevention of gastrointestinal complications is the use of proton pump inhibitors.
