Abstract


Abstract: Lansoprazole and omeprazole is a Proton Pump Inhibitor class of drugs that are often used for the treatment of peptic ulcers. Lansoprazole and omeprazole have an influence on the various target organs exposed. Mechanism of lansoprazole and omeprazole in influencing the activity of the enzyme catalase is competing with absolute catalase enzyme substrate (H2O2) in the binding of the enzyme active site. This study aims to determine the effect of lansoprazole and omeprazole against liver catalase enzyme activity. This study was a laboratory experimental study conducted in three groups, namely the control group (P0), the treatment group (P1) is given lansoprazole 30 mg and a treatment group (P2) given omeprazole 20 mg. The result showed the value of Km of the control group (P0) of 13.482 mmol/dm3, the treatment group (P1) of 11,227 mmol/dm3 and the treatment group (P2) of 6,327 mmol/dm3. Analysis of statistical data shows the regression correlation value of p for P1 was 0,01 adn for P2 was 0,02 (p <0.05) and the R value approaching 1 with a linear graph Lineweaver Burk meaningful. Concluded that lansoprazole and omeprazole may affect the activity of the liver enzyme catalase.

Abstrak: Lansoprazol dan omeprazol merupakan obat golongan proton pump inhibitor yang sering digunakan untuk pengobatan tukak lambung. Lansoprazol dan omeprazol memiliki berbagai pengaruh terhadap organ target yang terpajan. Mekanisme lansoprazol dan omeprazol dalam mempengaruhi aktivitas enzim katalase adalah berkompetisi dengan substrat absolut enzim katalase (H2O2) dalam mengikat sisi aktif enzim. Penelitian ini bertujuan untuk mengetahui pengaruh lansoprazol dan omeprazol terhadap aktivitas enzim katalase hepar. Penelitian ini merupakan penelitian quasi eksperimental yang dilakukan pada 3 kelompok, yakni kelompok kontrol (P0), kelompok perlakuan (P1) diberikan lansoprazol 30 mg dan kelompok perlakuan (P2) diberikan omeprazol 20 mg. Hasil penelitian didapatkan nilai Km pada kelompok kontrol (P0) sebesar 13,482 mmol/dm3, pada kelompok perlakuan (P1) sebesar 11,227mmol/dm3 dan pada kelompok perlakuan (P2) sebesar 6,327mmol/dm3. Analisis data statistik korelasi regresi menunjukkan nilai p pada P1 0,01 dan pada P2 0,02 (p<0,05) serta nilai R mendekati 1 dengan grafik linear Lineweaver Burk yang menanjak. Disimpulkan bahwa lansoprazol dan omeprazol dapat mempengaruhi aktivitas enzim katalase hepar mencit.
