Nonsteroidal anti-inflammatory drugs (NSAIDs) cause gastrointestinal damage as one of their side effects in humans and experimental animals. Lipid peroxidation plays an important role in NSAID-induced ulceration. The aim of this study was to investigate the inhibitory effect of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors on the ulceration in small intestines of rats.
The effects of three HMG-CoA reductase inhibitors, fluvastatin, pravastatin and atorvastatin on ileal ulcer formation in 5-bromo-2-(4-fluorophenyl)-3-(4- methylsulfonylphenyl) thiophene (BFMeT)-treated rats were examined. Antioxidative activity of the inhibitors was measured by a redox-linked colorimetric method.
Fluvastatin, which was reported to have antioxidative activity, repressed the ileal ulcer formation in rats treated with BFMeT an NSAIDs. However, the other HMG-CoA reductase inhibitors (pravastatin and atorvastatin) did not repress the ileal ulcer formation. Among these HMG-CoA reductase inhibitors, fluvastatin showed a significantly stronger reducing power than the others (pravastatin, atorvastatin).

非甾体抗炎药(NSAIDs)在人类和实验动物中会导致胃肠道损伤,这是其副作用之一。脂质过氧化在NSAIDs诱导的溃疡形成中起重要作用。本研究的目的是探讨3-羟基-3-甲基戊二酰辅酶A(HMG-CoA)还原酶抑制剂对大鼠小肠溃疡形成的抑制作用。
研究了三种HMG-CoA还原酶抑制剂氟伐他汀、普伐他汀和阿托伐他汀对5-溴-2-(4-氟苯基)-3-(4-甲基磺酰苯基)噻吩(BFMeT)处理的大鼠回肠溃疡形成的影响。通过氧化还原偶联比色法测定抑制剂的抗氧化活性。
据报道具有抗氧化活性的氟伐他汀可抑制BFMeT(一种NSAIDs)处理的大鼠的回肠溃疡形成。然而,其他HMG-CoA还原酶抑制剂(普伐他汀和阿托伐他汀)并未抑制回肠溃疡形成。在这些HMG-CoA还原酶抑制剂中,氟伐他汀的还原能力明显强于其他药物(普伐他汀、阿托伐他汀)。
具有抗氧化活性的氟伐他汀可抑制NSAIDs诱导的大鼠溃疡形成。
