Usage And Synthesis

Uses

Allopurinol sodium is a potent and orally active xanthine oxidase inhibitor with an IC50 value of 0.2-50 μM. Allopurinol sodium can be used in the research of hyperuricemia and gout. Allopurinol sodium decreases the expression of HIF-1α and HIF-2α protein. Allopurinol sodium shows anti-depressant and anti-nociception activity. Anti-leishmanial effect[1][2][3][4][5].

in vivo

Allopurinol sodium (39 mg/kg; p.o.; daily for 21 successive days) shows anti-depressant activity in mouse^[3].
Allopurinol sodium (10-400 mg/kg; i.p.) induces anti-nociception activity in mouse^[4].

Animal Model:	20-30 g, male Swiss Albino mice^[3]
Dosage:	39 mg/kg
Administration:	P.o.; daily for 21 successive days
Result:	Reduced the immobility time in the FST with the immobility time of 129.8±10.5 s.

Animal Model:	30-40 g, male adult Swiss albino mice^[4]
Dosage:	10, 50, 100, 200, 400 mg/kg
Administration:	I.p.
Result:	Produced dose-dependent anti-nociception in the tail-flick, hot-plate.
