Claims19
A film dosage composition comprising:
- a. A polymeric carrier matrix;
- b. A therapeutically effective amount of buprenorphine or a pharmaceutically acceptable salt thereof;
- c. A therapeutically effective amount of naloxone or a pharmaceutically acceptable salt thereof;
- and
- d. A buffer in an amount to provide a local pH for said composition of a value sufficient to optimize absorption of said buprenorphine, wherein said local pH is from about 3 to about 3.5 in the presence of saliva.
A method of treating narcotic dependence of a user, comprising the steps of:
- a. providing a composition comprising:
- i. A polymeric carrier matrix;
- ii. A therapeutically effective amount of buprenorphine or a pharmaceutically acceptable salt thereof;
- iii. A therapeutically effective amount of naloxone or a pharmaceutically acceptable salt thereof;
- and
- iv. A buffer in an amount to provide a local pH of about 3 to about 3.5 for said composition of a value sufficient to optimize absorption of said buprenorphine and also sufficient to inhibit absorption of said naloxone;
- and
- b. administering said composition to the oral cavity of a user.
An orally dissolving film formulation comprising buprenorphine and naloxone, wherein said formulation provides an in vivo plasma profile having a Cmax of between about 0.624 ng/ml and about 5.638 ng/ml for buprenorphine and an in vivo plasma profile having a Cmax of between about 41.04 pg/ml to about 323.75 pg/ml for naloxone.
