Prostaglandin analog compositions to treat epithelial-related conditions
The present invention relates to the formulation and delivery of prostaglandin analogs to treat epithelial-related condition. In some embodiments, the compositions of the invention are used to stimulate hair growth. In some embodiments, the compositions of the invention are used to restore hair color to depigmented hair.
1. A topical composition for treating an epithelial-related condition, wherein the epithelial-related condition is a condition selected from the group consisting of sparse hair growth, short hair growth, thin hair growth, alopecia, and hair de-pigmentation, The topical composition comprising the steps:
(a) a compound of formula XII or a salt of formula XII:
wherein
the simple straight line represents a bond lying approximately in the surface plane; the wedge shaped bond is directed to the front of surface plane; and the hatched bond is directed in the back of the surface plane; and
wherein the compound has optically active isomers whenever chiral centers are present; and wherein the compound of formula XII is 16-(3-chlorophenoxy)-17,18,19,20-tetranor PGF 2α cyclopropyl methyl amide; whereby the composition stimulates hair growth on an epithelial surface to which the composition has been applied; and
(b) a earner.
2. The topical composition according to claim 1 , wherein the composition is an ophthalmic composition.
3. The topical composition according to claim 1 , further comprising the step of restoring pigmentation to depigmented hair.
4. The topical composition according to claim 1 , wherein the epithelial-related condition is alopecia.
5. The topical composition according to claim 1 , wherein the epithelial surface onto which the composition is applied topically is an eyelid.
6. The topical composition according to claim 1 , wherein the epithelial-related condition is alopecia of at least one eyelash.
7. The topical composition according to claim 1 , wherein the epithelial surface onto which the composition is applied topically is a face.
8. The topical composition according to claim 1 , wherein the condition is alopecia of at least one eyebrow.
9. The topical composition according to claim 1 , wherein the epithelial surface onto which the composition is applied topically is a scalp.
10. The topical composition according to claim 1 , wherein the epithelial surface onto which the composition is applied topically is above a lip.
11. The topical composition of claim 1 , wherein the compound of (a) is present in a pharmaceutically effective amount.
12. The topical composition of claim 1 , wherein the compound of (a) is present in a cosmetically effective amount.
13. The topical composition of claim 1 , wherein the compound of (a) is present in a cosmeceutically active amount.
