OPIOID AND METHODS OF MAKING AND USING THE SAME
An opioid derivative of oxymorphol, called 8-hydroxy-6-α-oxymorphol, has been discovered. This opioid is believed to bind at least to mu-opioid receptors and produce an analgesic or anti-tussive effect. Pharmaceutically acceptable salts of 8-hydroxy-6-α-oxymorphol, and pharmaceutical compositions comprising 8-hydroxy-6-α-oxymorphol or pharmaceutically acceptable salts thereof and pharmaceutically acceptable carrier, are also provided.
1 . 8-hydroxy-6-α-oxymorphol.
2 . A composition comprising an isolated or purified 8-hydroxy-6-α-oxymorphol, or a pharmaceutically acceptable salt thereof.
3 . A pharmaceutical composition comprising 8-hydroxy-6-α-oxymorphol, or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable carrier.
4 . The pharmaceutical composition of claim 3 , comprising a dosage form selected from the group consisting of a powder, liquid, syrup, suspension, solid and semi-solid formulation.
5 . The pharmaceutical composition of claim 3 , comprising a topical or transdermal delivery form.
6 . The pharmaceutical composition of claim 3 , comprising a dosage form selected from the group consisting of a parenteral, sublingual and buccal dosage form.
7 . The pharmaceutical composition of claim 3 , comprising a controlled or extended release dosage form.
8 . The pharmaceutical composition of claim 3 , further comprising at least one active pharmaceutical ingredient other than 8-hydroxy-6-α-oxymorphol or a pharmaceutically acceptable salt thereof.
9 . The pharmaceutical composition of claim 8 , wherein the at least one active pharmaceutical ingredient other than 8-hydroxy-6-α-oxymorphol or a pharmaceutically acceptable salt thereof comprises an opioid.
10 . A method of treating or preventing pain or cough in a subject, comprising the step of administering to the subject a therapeutically effective amount of:
(1) 8-hydroxy-6-α-oxymorphol or a pharmaceutically acceptable salt thereof; or
(2) a pharmaceutical composition comprising 8-hydroxy-6-α-oxymorphol or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier.
11 . The method of claim 10 , wherein the 8-hydroxy-6-α-oxymorphol or pharmaceutically acceptable salt thereof, or the pharmaceutical composition, is administered by injection, orally, topically, parenterally, nasally, transdermally, rectally, sublingually or buccally, or by an implanted reservoir.
12 . The method of claim 11 , wherein the injection is selected from the group consisting of intrathecal, intramuscular, intravascular, intraarticular and subcutaneous injection.
13 . The method of claim 10 , wherein the pharmaceutical composition comprises a dosage form selected from the group consisting of a powder, liquid, syrup, suspension, solid and semi-solid formulation.
14 . The method of claim 10 , wherein the pharmaceutical composition comprises a topical or transdermal delivery form.
15 . The method of claim 10 , wherein the pharmaceutical composition comprises a dosage form selected from the group consisting of a parenteral, sublingual and buccal dosage form.
16 . The method of claim 10 , wherein the pharmaceutical composition further comprises at least one active pharmaceutical ingredient other than 8-hydroxy-6-α-oxymorphol or a pharmaceutically acceptable salt thereof.
17 . The method of claim 16 , wherein the at least one active pharmaceutical ingredient other than 8-hydroxy-6-α-oxymorphol or a pharmaceutically acceptable salt thereof comprises an opioid.
