1. A tablet for oral administration with reduced potential for parenteral abuse, said tablet comprising:
- (a) one or more active ingredients having potential for abuse selected from the group consisting of hydrocodone, morphine, oxycodone, tramadol, and pharmaceutically acceptable salts and solvates thereof; and
(b) at least one viscosity-increasing agent in a quantity such that an aqueous extract of a total content of the tablet when comminuted and combined with 10 ml of water at 25°
C. forms a gel that can be drawn up into and injected back out of a hypodermic needle having a diameter of 0.9 mm, into a further quantity of water, wherein threads of the gel injected from said needle remain visible to the naked eye in said further quantity of water at 37°

Abstract
A solid administration form, protected from parenteral abuse and containing at least one viscosity-increasing agent in addition to one or more active substances that have parenteral abuse potential. The agent forms, when a necessary minimum amount of an aqueous liquid is added, on the basis of an extract obtained from the administration form, a preferably injectable gel that remains visually distinct when introduced into another quantity of an aqueous liquid.

13. A solid dosage form for oral administration with reduced potential for parenteral abuse, said dosage form comprising:
-
(a) one or more active ingredients having potential for abuse selected from the group consisting of hydrocodone, morphine, oxycodone, tramadol, and pharmaceutically acceptable salts and solvates thereof; and (b) one or more viscosity-increasing components, in a total quantity, for all said components combined, that is equal to or greater than 5 mg per dosage form, that quantity being selected such that an aqueous extract of a total content of the dosage form, when comminuted and combined with 10 ml of water at 25°
C., forms a gel that is capable of being drawn into and then expelled from a hypodermic needle having a diameter of 0.9 mm, wherein threads of said gel, formed upon exit from said needle into a further quantity of water at 37°
C., remain visible to the naked eye. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
