Pharmaceutical compositions and methods for peptide treatment
Disclosed are compositions and methods for treating a patient with a pharmaceutically active agent other than insulin selected from the group consisting of peptides, peptidomimetics, and proteins, wherein the pharmaceutical composition is in the form of an emulsified nasal spray comprising: a macrocyclic permeation enhancer, a liquid carrier comprising water, and a therapeutically effective amount of a pharmaceutically active agent other than insulin selected from the group consisting of peptides, peptidomimetics, and proteins; wherein the macrocyclic permeation enhancer is a Hsieh enhancer emulsified in the liquid carrier.

A pharmaceutical composition in the form of an emulsion suitable for delivery to a mucous membrane comprising: a macrocyclic permeation enhancer, a liquid carrier, a hydrocolloid emulsifying agent, and a therapeutically effective amount of a pharmaceutically active agent other than insulin selected from the group consisting of peptides and proteins; wherein said macrocyclic permeation enhancer is a Hsieh enhancer; said Hsieh enhancer having the following structure:
wherein X and Y are oxygen, sulfur or an imino group of the structure
or ═N—R with the proviso that when Y is the imino group of the structure ═N—R, X is an imino group of the structure
and when Y is sulfur, X is sulfur on an imino group of the structure
A is a group having the structure

2. The pharmaceutical composition of claim 1 , wherein said Hsieh enhancer is selected from the group consisting of 3-methylcyclopentadecanone, 9-cycloheptadecen-1-one, cyclohexadecanone, cyclopentadecanone, oxacyclohexadecan-2- one and mixtures thereof.
3. The pharmaceutical composition of claim 1 , further comprising a crystallization inhibitor.
4. The pharmaceutical composition of claim 1 , further comprising an enzyme inhibitor.
5. The pharmaceutical composition of claim 4 , wherein said enzyme inhibitor is selected from the group consisting of leupeptin and aprotinin.
6. The pharmaceutical composition of claim 1 , further comprising a non-ionic surfactant or combination of non-ionic surfactants.
7. The pharmaceutical composition of claim 6 , wherein said non-ionic surfactant or combination of non-ionic surfactants has an HLB of from about 7 to about 14.
8. The pharmaceutical composition of claim 1 , further comprising a pH modifier.
9. A method for treating a patient with a peptide or a protein, said method comprising administering to a patient in need of peptide treatment or protein treatment , a pharmaceutical composition in the form of an emulsion suitable for delivery to a mucous membrane comprising; a macrocyclic permeation enhancer, a liquid carrier, a hydrocolloid emulsifying agent, and a therapeutically effective amount of a pharmaceutically active agent other than insulin selected from the group consisting of peptides and proteins; wherein said macrocylic permeation enhancer is a Hsieh enhancer; said Hsieh enhancer having the following structure:
wherein X and Y are oxygen, sulfur or an imino group of the structure
or ═N—R with the proviso that when Y is the imino group of the structure ═N—R, X is an imino group of the structure
and when Y is sulfur, X is sulfur or an imino group of the structure
A is a group having the structure
wherein X and Y are defined above, m and n are integers having a value from 1 to 20 and the sum of m+n is not greater than 25, p is an integer having a value of 0 or 1, q is an integer having a value of 0 or 1, r is an integer having a value of 0 or 1, and each of R, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is independently hydrogen or an alkyl group having from 1 to 6 carbon atoms which may be straight chained or branched provided that only one of R 1 to R 6 can be an alkyl group, with the proviso that when p. q and r have a value of 0 and Y is oxygen, m+n is at least 11, and with the further proviso that when X is an imino group, q is equal to 1, Y is oxygen, and p and r are), then m+n is at least 11.
