Abstract
The present disclosure includes compositions of a semi-crystalline or crystalline pharmaceutically active agent dispersed in a polymer matrix, in which the active agent is less degraded and, therefore, has lower level of impurities. The present disclosure further includes a method of reducing or preventing physical and chemical degradation of a semi-crystalline or crystalline active agent pharmaceutically active agent dispersed in a polymer matrix. A method of preparation of the composition is also included in this disclosure.
Claims
exact text as granted — not AI-modified1 . An ocular composition comprising a polymer matrix and a semi-crystalline or crystalline pharmaceutically active agent, wherein the active agent is dispersed in the polymer matrix.
2 . The composition of claim 1 , wherein the pharmaceutically active agent is bimatoprost.
3 . The composition of claim 2 , wherein the composition comprises about 2% or less impurities.
4 . (canceled)
5 . The composition of claim [[4]]3, wherein the composition comprises about 1% or less 15-keto bimatoprost.
6 .- 7 . (canceled)
8 . The composition of claim 3 , wherein the impurities comprise 5-trans bimatoprost.
9 . The composition of claim 8 , wherein the composition comprises about 0.1% to about 1% 5-trans bimatoprost.
10 . The composition of claim 9 , wherein the composition comprises about 0.1% 5-trans bimatoprost and about 1% 15-keto bimatoprost.
11 . (canceled)
12 . The composition of claim 2 , wherein the semi-crystalline or crystalline bimatoprost is chemically stable in the composition for 760 days.
13 . The composition of claim 1 , wherein the matrix comprises a thermosetting polymer or a thermoplastic polymer.
14 . The composition of claim 13 , wherein the thermosetting polymer is silicone.
15 . The composition of claim 14 , wherein the silicone is MED-4810, MED-4820, MED-4830, MED-4840, MED-4842, MED1-4855, MED-4860, MED-4870, MED-4880, or equivalents thereof.
16 . The composition of claim 1 , wherein the composition is configured as an ocular insert.
17 . The composition of claim 16 , wherein the ocular insert is a ring shaped ocular insert.
18 . The composition of claim 17 , wherein the ring has a diameter of about 10 mm to about 40 mm and a cross-sectional thickness of about 0.1 mm to about 1.5 mm.
19 . (canceled)
20 . The composition of claim 1 , wherein the active agent is about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 11%, about 12%, about 13%, about 14%, about 15%, about 16%, about 17%, about 18%, about 19%, about 20%, about 21%, or about 22% by weight of the composition.
21 .- 61 . (canceled)
62 . A method of treating a disease or disorder of an eye of a subject in need thereof comprising placing an ocular insert in an eye of the subject, wherein the ocular insert comprises a polymer matrix and a semi-crystalline or crystalline pharmaceutically active agent dispersed in the polymer matrix.
63 . The method of claim 62 , wherein the pharmaceutically active agent is bimatoprost.
64 . The method of claim 62 , wherein the ocular insert comprises about 2% or less impurities.
65 . The method of claim 64 , wherein the ocular insert comprises about 1% or less 15-keto bimatoprost.
66 . The method of claim 64 , wherein the impurities comprise 5-trans bimatoprost.
67 . The method of claim 66 , wherein the ocular insert comprises about 0.1% 5-trans bimatoprost to about 1% 5-trans bimatoprost.
68 . The method of claim 62 , wherein the semi-crystalline or crystalline bimatoprost is chemically stable in the composition for 760 days.
69 . The method of claim 62 , wherein the matrix comprises a thermosetting polymer or a thermoplastic polymer.
70 . The method of claim 69 , wherein the thermosetting polymer is silicone.
71 . The method of claim 70 , wherein the silicone is MED-4810, MED-4820, MED-4830, MED-4840, MED-4842, MED1-4855, MED-4860, MED-4870, MED-4880, or equivalents thereof.
72 . The method of claim 62 , wherein the ocular insert is a ring shaped ocular insert.
73 . The method of claim 72 , wherein the ring has a diameter of about 10 mm to about 40 mm and a cross-sectional thickness of about 0.1 mm to about 1.5 mm.
74 . The method of claim 62 , wherein the active agent is about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 11%, about 12%, about 13%, about 14%, about 15%, about 16%, about 17%, about 18%, about 19%, about 20%, about 21%, or about 22% by weight of the composition.
75 . The method of claim 62 , wherein the method lowers intraocular pressure.
76 . The method of claim 62 , wherein the disease or disorder is Glaucoma or dry eye syndrome.Cited by (0)
