Abuse-resistant controlled-release opioid dosage form

A method of treating a patient with an opioid agonist comprising:

• providing an analgesic composition in capsule form comprising, in % by weight:
• opioid agonist;
• and
• an opioid antagonist in an amount that is orally effective to block an opioid effect caused by the opioid agonist;
• ammonio methacrylate copolymer, NF;
• up to about 5% sodium lauryl sulfate, NF;
• and
• up to about 5% magnesium stearate, NF;
• wherein said composition comprises 1) a controlled release formulation containing the opioid agonist that controls the release rate of the opioid agonist such that therapeutic agonist levels are maintained and 2) a controlled release formulation containing the antagonist which is not released unless the capsule is crushed but is released as an immediate release formulation when the capsule is crushed;
• maintaining the capsule substantially intact;
• and
• orally administering the substantially intact capsule to a patient.
