Abstract
The present invention relates to apparatus, methods, and processes for making solid dosage forms comprising at least one active ingredient, a core and shell configuration, wherein the shell comprises a hardenable material, such as a thermal-gelling polymer, for example gelatin; and the shell is provided with at least one opening. The opening(s) are formed while the shell is still in a softened state.
Claims
exact text as granted — not AI-modified1 - 24 . (canceled)
25 . A process for making a dosage form that comprises a core and a shell surrounding at least a portion of the core and having one or more openings comprising:
a) providing a shell over at least a portion of the compressed core; and b) providing at least one opening in said shell, wherein the shell is soft at the time the opening is provided in said shell.
26 . The process according to claim 25 , wherein one or more openings contact the core.
27 . The process according to claim 25 , wherein the soft shell has a water content at least 20% greater than its moisture content at equilibrium at 25° C. and 60% relative humidity.
28 . The process according to claim 25 , wherein the core comprises at least one active ingredient.
29 . The process according to claim 28 , wherein the dosage form provides for immediate release of at least one active ingredient contained in the core.
30 . The process according to claim 25 , wherein the core comprises a compressed tablet.
31 . The process according to claim 25 , wherein the compressed tablet has a hardness from about 1 to about 30 kp/cm2.
32 . The process according to claim 25 , wherein the shell comprises gelatin.
33 . The process according to claim 25 , wherein the average thickness of the shell, excluding uncoated or exposed areas, is in the range from about 100 to about 400 microns.
34 . The process according to claim 25 , wherein the diameter or width of the one or more openings is from about 200 to about 2000 microns.
35 . The process according to claim 26 , wherein the soft shell has a water content at least 20% greater than its moisture content at equilibrium at 25° C. and 60% relative humidity.
36 . The process according to claim 26 , wherein the core comprises at least one active ingredient.
37 . The process according to claim 36 , wherein the dosage form provides for immediate release of at least one active ingredient contained in the core.
38 . The process according to claim 26 , wherein the core comprises a compressed tablet.
39 . The process according to claim 26 , wherein the compressed tablet has a hardness from about 1 to about 30 kp/cm2.
40 . The process according to claim 26 , wherein the shell comprises gelatin.
41 . The process according to claim 26 , wherein the average thickness of the shell, excluding uncoated or exposed areas, is in the range from about 100 to about 400 microns.
42 . The process according to claim 26 , wherein the diameter or width of the one or more openings is from about 200 to about 2000 microns.
43 . The process according to claim 29 , wherein the average thickness of the shell, excluding uncoated or exposed areas, is in the range from about 100 to about 400 microns.
44 . The process according to claim 37 , wherein the diameter or width of the one or more openings is from about 200 to about 2000 microns.Join the waitlist — get patent alerts
