Evaluating the Efficacy and Safety of Antihypertensive Drugs in the Treatment of Congenital Heart Disease in Paediatric Patients: A Comprehensive Study

Abstract

CHD is the most common of all congenital anomalies causing mortality among children, characterized by structural abnormalities present at birth that vary in severity and complexity. Increased cardiac workload due to CHD may stipulate a growth delay in the affected children. The complexity of treatment is further compounded by medication errors, and hence, rigorous strategies of evaluation and management become necessary. This study was conducted to determine antihypertensive drug consumption patterns and to evaluate their therapeutic efficacy among 92 patients with CHD to meet the evaluation criteria, including appropriateness of treatment for the condition of the patient, adherence to indications, accuracy of dosage, and drug use practice. Females constituted the highest proportion of patients at 53.26 percent, infants were the most common age group at 43.48 percent, and Atrial seal defect accounted for 22.5 percent of the CHD patients. The antihypertensive drugs predominantly prescribed are Furosemide, used by 44.9% of the subjects, followed by Captopril, used by 30.3%, and Spironolactone, used by 10.1%. Therapy was evaluated for its effectiveness; appropriateness, both for the patient's indications and drug usage, was found to be very high, at 98.9% and 97.8%, respectively, whereas adherence to prescribed dosage was relatively lower at 62.7%. This study points toward further challenges in the management of antihypertensive treatment among children with CHD. It needs combined efforts by a pediatric cardiologist, pharmacist, nurse, and caregiver for total care to reduce the risk from treatment. Continuous monitoring and alterations in the plan of treatment, coupled with education, could be significant in optimizing medication adherence to improve long-term health outcomes in CHD children. The research done in this field, at large, improves pediatric cardiology practice to reduce morbidity and mortality rates associated with congenital heart disease around the world.
