Abstract

Schizophrenic patients who used antidepressant combination drug therapy in their treatment can cause drug interaction. This study aimed to determine the potential drug interactions of antidepressant in schizophrenic patients. The study designed was cross-sectional by random sampling. The samples were secondary data from outpatient prescriptions and medical record of schizophrenic patients in Psychiatric Hospital Dr. Soeharto Heerdjan during 2016. From 743 drug prescriptions, it was found that 694 (91.41%) drug prescriptions having 1286 (61.24%) cases of drug interaction. The most common interaction were fluoxetine and risperidone in 376 cases (29.24%). The proportion based on interaction level was 1246 cases (96.89%) for severe, 34 cases (2.64%) for moderate, and 6 cases (0.47%) for minor. The study concluded that antidepressant prescribing needs to be closely monitored because of high incidence in drug interactions or modified when the negative impact was greater than the positive impact.

Bahasa Abstract

Pasien skizofrenia yang menggunakan terapi obat kombinasi antidepresan dalam pengobatannya dapat menimbulkan interaksi obat. Penelitian ini bertujuan untuk mengetahui potensi interaksi obat golongan antidepresan pada pasien skizofrenia. Desain penelitian ini menggunakan cross sectional. Data yang digunakan adalah data sekunder dari resep dan rekam medis pasien skizofrenia rawat jalan di RSJ Dr. Soeharto Heerdjan tahun 2016 dengan metode retrospektif. Pengambilan sampel dilakukan secara acak. Data sampel yang dianalisis sebanyak 743 lembar resep dan sebanyak 694 (91,41%) lembar resep terdapat interaksi obat dengan jumlah kasus interaksi sebanyak 1286 kasus (61,24%). Jenis interaksi obat yang paling banyak ditemukan adalah fluoksetin dan risperidon sebanyak 376 kasus (29,24%). Tingkat keparahan interaksi mayor sebanyak 1246 kasus (96,89%), moderat sebanyak 34 kasus (2,64%) dan minor sebanyak 6 kasus (0,47%). Tingginya kejadian interaksi obat pada peresepan antidepresan memerlukan pemantauan yang ketat, dan bila perlu dimodifikasi ketika dampak negatif yang ditimbulkan lebih besar daripada dampak positif.
