Embodiment 1-1 to 1-3 and comparative Embodiment 1
[0082] Examples 1-1 to 1-3 and Comparative Example 1: Preparation of Capsules and Effects Dependent on Capsule Components
[0083] Due to restrictions on the amount of material allowed for soft capsules (which will be used to encapsulate omega-3 fatty acid ester oil), soft capsules with different compositions were prepared and stability tests were carried out to determine Proper mixing ratio between glycan solutions.
[0084] 1) Preparation of capsules
[0085] By following the ingredients described in Table 2, and using conventional methods, soft or hard gelatin capsules were prepared, followed by filling the gelatin thus obtained with 1,000 mg of omega-3 fatty acid ester oil (KD pharma, Germany, EP grade) capsules to obtain capsules of Examples 1-1 to 1-3 and Comparative Example 1. Sorbitol sorbitan solutions were used as plasticizers for the capsules of Examples 1-1 to 1-3, and glycerin was used for the capsules of Comparative Example 1. In addition, a small amount of ...
Embodiment 2
[0094] Embodiment 2: Preparation of oral compound preparation comprising rosuvastatin
[0095] The first and second coatings were applied according to the ingredients described in Table 3, using the capsules of Example 1-1 as the core. For the first coat, hydroxypropylmethylcellulose (HPMC), polyethylene glycol (PEG), polyvinylpyrrolidone (PVP) and ethylcellulose (Aqualon N7 grade, ASHLAND) were dissolved in a weight ratio of 3 : 7 mixed solvent of ethanol and water, and then by means of the mixture thus obtained and using a coating device (Sejong, SFC-30) for water-resistant coating. Subsequently, for the second coat, rosuvastatin calcium, alkaline stabilizer (MgCO 3 ), polyvinylpyrrolidone and polyvinyl alcohol-polyethylene glycol graft copolymer (Kollicoat IR, BASF) were dissolved in a mixed solvent of ethanol and water at a weight ratio of 3:7, and then by means of the mixture thus obtained and using A coating device (Sejong, SFC-30) was used for the second coating follo...
Embodiment 3 and 4
[0106] Examples 3 and 4: Preparation of Oral Compound Preparations Containing Atorvastatin
[0107] The first and second coatings were applied according to the ingredients described in Table 4 and using the capsules of Example 1-1 as the core. For the first coating, hydroxypropylmethylcellulose (HPMC), polyethylene glycol, polyvinylpyrrolidone, and ethylcellulose were dissolved in a mixed solvent of ethanol and water at a weight ratio of 3:7, and then A water-resistant coating was performed on the mixture thus obtained using a coating device (Sejong, SFC-30). Subsequently, for the second coat, atorvastatin calcium, alkaline stabilizer, polyvinylpyrrolidone and polyvinyl alcohol-polyethylene glycol graft copolymer were dissolved in a mixture of ethanol and water in a weight ratio of 3:7 solvent, and then a second coating was performed by means of the mixture thus obtained using a coating device (Sejong, SFC-30), followed by drying to obtain the oral compound preparations of Ex...
