Compositions and methods for buccal delivery of human growth hormone
View Patent ↗The present invention provides pharmaceutical compositions for buccal delivery of human growth hormone (hGH) comprising a delivery agent and hGH. The compositions of the present invention provide improved delivery of hGH compared to comparable oral compositions, resulting in increased serum concentrations of hGH. The present invention further provides for methods of stimulating tissue growth in an animal by buccally co-administering hGH and a delivery agent.
1. A pharmaceutical composition for buccal administration comprising a delivery agent, hGH, and a pharmaceutically acceptable ingredient for facilitating buccal administration,
wherein the delivery agent is selected from 8-(4-hydroxyphenoxy)octanoic acid, N-(8-[2-hydroxybenzoyl]-amino)caprylic acid, N-(10-[2-hydroxybenzoyl]-amino)decanoic acid, N-(8-[2-hydroxy-4-methoxybenzoyl]-amino)caprylic acid, N-(8-[2-hydroxy-5-chlorobenzoyl]-amino)caprylic acid, N-(4-[2-hydroxy-4-chlorobenzoyl]-amino)butanoic acid, and pharmaceutically acceptable salts thereof.
2. The composition of claim 1 , wherein the delivery agent is 8-(4-hydroxyphenoxy)octanoic acid, or a pharmaceutically acceptable salt thereof.
3. The composition of claim 1 , wherein the delivery agent is N-(8-[2-hydroxybenzoyl]-amino) caprylic acid, or a pharmaceutically acceptable salt thereof.
4. The composition of claim 1 , wherein the delivery agent is a sodium salt of N-(8-[2-hydroxybenzoyl]-amino) caprylic acid.
5. The composition of claim 1 , wherein the delivery agent is N-(10-[2-hydroxybenzoyl]-amino) decanoic acid, or a pharmaceutically acceptable salt thereof.
6. The composition of claim 1 , wherein the delivery agent is a sodium salt of N-(10-[2-hydroxybenzoyl]-amino)decanoic acid.
7. The composition of claim 1 , wherein the delivery agent is N-(8-[2-hydroxy-4-methoxybenzoyl]-amino) caprylic acid, or a pharmaceutically acceptable salt thereof.
8. The composition of claim 1 , wherein the delivery agent is N-(8-[2-hydroxy-5-chlorobenzoyl]-amino) caprylic acid, or a pharmaceutically acceptable salt thereof.
9. The composition of claim 1 , wherein the delivery agent is N-(4-[2-hydroxy-4-chlorobenzoyl]-amino) butanoic acid, or a pharmaceutically acceptable salt thereof.
10. The composition of claim 1 , wherein the composition is in the form of a gel.
11. A method of administering a hGH component comprising bucally administering an effective amount of the pharmaceutical composition of claim 1 .
12. A method for treating growth hormone deficiency in a patient in need thereof comprising bucally administering an effective amount of the pharmaceutical composition of claim 1 .
