Summary
Ilaprazole (IY-81149) sodium is an orally active proton pump inhibitor. Ilaprazole sodium irreversibly inhibits H + /K + -ATPase in a dose-dependent manner with an IC 50 of 6 μM in rabbit parietal cell preparation. Ilaprazole sodium is used for the research of gastric ulcers. Ilaprazole sodium is also a potent TOPK (T-lymphokine-activated killer cell-originated protein kinase) inhibitor [1] [2] .
In Vitro
On cumulation of 14C-aminopyrine in histamine stimulated parietal cells, the IC 50 of Ilaprazole (IY-81149) sodium is 9 nM [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Ilaprazole sodium (3-30 mg/kg; i.d.) dose-dependently inhibits gastric acid secretion
[1]
.
In anesthetized rats, Ilaprazole sodium dose-dependently increases gastric pH which is lowered by histamine infusion. In the case of i.v. injection, the ED
50
of Ilaprazole sodium and Omeprazole is 1.2 and 1.4 mg/kg and in the case of i.d. administration, the ED
50
of Ilaprazole sodium and omeprazole is 3.9 and 4.1 mg/kg, respectively. Ilaprazole sodium also significantly inhibits pentagastrin-stimulated gastric secretion. Its ED
50
is 2.1 mg/kg and that of Omeprazole was 3.5 mg/kg with i.d. administration. In the case of i.v. injection, Ilaprazole sodium is equipotent to Omeprazole. Ilaprazole sodium also inhibits gastric acid secretion strongly in fistular rats. The ED
50
of Ilaprazole sodium administered intraduodenally is 0.43 mg/kg and that of omeprazole Is 0.68 mg/kg
[1]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
| Animal Model: | Male SD rat (after pylorus ligation) [1] |
| Dosage: | 3, 10, 30 mg/kg |
| Administration: | Intraduodenally |
| Result: | The acid output and volume significantly inhibited by about 60 % and 46 % at 3 mg/kg were s, respectively. At 30 mg/kg, it showed 93 % and 73 % inhibition on acid output and volume, respectively. |
