Eighty United States students in Mexico received either loperamide (an initial dose of 4 mg, followed by 2 mg after passage of each unformed stool, up to 8 mg/d; 40 patients) or loperamide (at the same dosage schedule) plus an oral rehydration therapy (ORT) preparation (500 mL initially, followed by 250 mL after each subsequently passed unformed stool, up to 1,000 mL per 24 hours; 40 patients)....
The efflux transporter P-glycoprotein, expressed at high levels at the blood-brain barrier, exerts a profound effect on the disposition of various therapeutic compounds in the brain. A rapid and efficient modulation of this efflux transporter could enhance the distribution of its substrates and thereby improve central nervous system pharmacotherapies. This study explored the impact of the intra...
A major functional component of the blood-brain barrier is P-glycoprotein. In principle, inhibition of this efflux transporter would permit greater distribution of its substrates into the brain and increased central effects. Tariquidar and elacridar, potent and selective P-glycoprotein inhibitors, were investigated in this regard using the opioid loperamide as an in vivo probe in mice. Pretreat...
To date, the in vitro–in vivo correlation (IVIVC) of P-glycoprotein (P-gp)–mediated drug-drug interaction (DDI) at the blood-brain barrier (BBB) in rats indicated that the cutoff value to significantly affect the brain penetration of digoxin was [I,unbound/Ki] of 1, where I,unbound is the unbound plasma concentration of P-gp inhibitors. On the basis of the IVIVC in rats, we speculated that clin...
