The advent of angiotensin II type 1 receptor blockers (ARBs) as intriguing
gastroprotective candidates and the superior pharmacokinetics and
pharmacodynamics displayed by irbesartan compared to many other ARBs raised the
interest to investigate its gastroprotective potential in a rat model of gastric
injury. Irbesartan (50?mg/Kg) was orally administered to male Wistar rats once
daily for 14 days; thereafter gastric injury was induced by indomethacin
(60?mg/Kg, p.o). Irbesartan reduced gastric ulcer index, gastric acidity, and
ameliorated indomethacin-induced gastric mucosal apoptotic and inflammatory
aberrations, as demonstrated by hampering caspase-3, prostaglandin E(2) and tumor
necrosis factor-alpha levels and cyclooxygenase-2 mRNA expression. This ARB
increased mucosal dimethylarginine dimethylaminohydrolase-1 (DDAH-1) gene
expression and decreased elevated levels of matrix metalloproteinase-9,
asymmetric dimethylarginine (ADMA), epidermal growth factor receptor (EGFR) mRNA
and phosphorylated extracellular signal-regulated kinase 1 and 2 (pERK1/2).
Histopathological evaluation corroborated biochemical findings. Overall efficacy
of irbesartan was comparable to ranitidine, the widely used H(2) receptor
blocker. In conclusion, irbesartan exerts significant gastroprotection against
indomethacin-induced mucosal damage via acid-inhibitory, anti-inflammatory,
anti-apoptotic and extracellular matrix remodeling mechanisms that are probably
mediated, at least partly, by down-regulating DDAH/ADMA and EGFR/ERK1/2
signaling.
