Background:

Sodium Picosulfate is a laxative.

Sodium Picosulfate is a laxative that inhibits water and electrolytes absorption and increases their secretion. In cultured human, rat and rabbit liver cells, sodium picosulfate (1600 μg/ml) reduced the protein content in rabbit liver cells. Also, hepatocytes of rabbit were more sensitive to sodium picosulfate [1].

In patients underwent a barium enema, sodium picosulphate reduced the serum concentrations of sodium, potassium and urea by 1.299, 0.163 and 0.556, respectively [2]. In patients with morphine sulphate induced constipation, sodium picosulfate was well-tolerated and significantly improved constipation with normal stool consistency, not requiring suppositories, manual evacuation or enemas [3]. In patients with chronic constipation, sodium picosulphate (7 mg) improved stool frequency and straining in 82.8% patients and reduced bloating [4].
