Abstract: The invention relates to a method of treatment using a solid oral pharmaceutical dosage form comprising an opioid receptor antagonist for use in the treatment of opioid induced constipation comprising the opioid antagonist equivalent to 24 mg of naloxone hydrochloride as twice daily formulation or equivalent to 48 mg of naloxone hydrochloride as once daily formulation, characterized in that the opioid antagonist has a rapid first pass metabolism with a plasma half-life of 2 hours or less in humans within the first 3 hours of oral administration of a solution, wherein the steady state pharmacokinetics result in a constant level of naloxone in the bloodstream, wherein the pharmacokinetics are independent of whether the dosage is administered once or twice daily, wherein the oral dosage form releases the opioid antagonist in a prolonged manner, wherein the in vitro release rate of the opioid antagonist measured using the paddle stirrer method according to Ph. Eur. at 75 rpm in 1000 ml 0.

Abstract: The present invention relates to a solid oral pharmaceutical composition comprising naloxone, or a pharmaceutical acceptable salt thereof, as an active substance, wherein the composition releases the active substance in a prolonged manner. In order to provide a composition that is suitable for an administration period of at least twelve-hours for the treatment of opioid-induced constipation, it is proposed that the composition should have an in vitro release rate of the active substance measured using the paddle stirrer method according to Ph. Eur. at 75 rpm in 500 ml 0.1 N hydrochloric acid at 37° C., of 0% to 75% in 2 h, of 3% to 95 % in 4 h, of 20% to 100% in 10 h, of 30% to 100% in 16 h, of 50% to 100% in 24 h, and of more than 80% in 36 h, wherein the composition has a IC50/Cmax value of at least 40. In an alternative embodiment, the composition can be a multilayer tablet.
