摘要:
A composition for enteric hard capsules, and an enteric hard capsule prepared using the composition. The composition for enteric hard capsules may include polyol having at least three hydroxyl groups. During the storage of the enteric hard capsule prepared using the composition, the separation of salt from the capsule is delayed.

An orthopedic appliance for a temporomandibular joint, includes: an upper teeth supporter and a lower teeth supporter, each of which includes a front arch portion corresponding to front teeth, and a pair of rear legs extended from the front arch portion, facing with each other and corresponding to a molar region; at least one set of upper and lower pivots which are respectively coupled to the upper teeth supporter and the lower teeth supporter and rotatable in at least one direction among forward, backward, leftward and rightward directions; and a connection member which connects the upper pivot and the lower pivot and adjusts a space between the upper pivot and the lower pivot. Thus, it is easy to adjust relative movement in a horizontal direction and height between the upper and lower teeth supporters.

摘要:
A method of preparing enteric hard capsules, and an enteric hard capsule prepared by the method. The method may include: dissolving an enteric base material, a capsule forming aid, and a neutralizing agent in water at room temperature to prepare an aqueous composition; heating the aqueous composition to a first temperature that is higher than a gelation start temperature of the aqueous composition; cooling the heated aqueous composition to a second temperature that is lower than the gelation start temperature; immersing a mold pin heated to a third temperature that is higher than the gelation start temperature into the aqueous composition; removing the mold pin from the aqueous composition to obtain a film coated on the mold pin; maintaining the film on the mold pin at a fourth temperature that is higher than the gelation start temperature for a first time period to fix the film onto the mold pin; and drying the fixed film at a fifth temperature for a second time period to obtain a capsule shell.

The aqueous composition for an enteric hard capsule includes an enteric base material, a capsule forming aid, and a neutralizing agent. The method of preparing an enteric hard capsule includes: preparing an aqueous composition by dissolving an enteric base material, a capsule forming aid, and a neutralizing agent in water; preheating the aqueous composition to a temperature that is less than the gelation temperature for the aqueous composition; immersing a mold pin heated to a temperature that is greater than the gelation temperature for the aqueous composition into the aqueous composition; taking the mold pin out of the aqueous composition to obtain a film formed on the mold pin; and maintaining the film at a temperature that is equal to or greater than the gelation temperature for the aqueous composition for a predetermined period of time to fix the film on the mold pin and drying the film.
