제목 The effects of crystallinity and solubility on release profile of nifedipine
초록 Among the various novel drug systems available in pharmaceutical industry , oral delivery systems hold the major part because of their obvious advantages of ease administration and better patient compliance.1
In present study, nifedipine(ND) beads were manufactured by fluidized-bed spray coating method, and used nifedipine(ND) produced by different companies. because the characters of durg would differ each companies. Crystallinity of NDs was examined by DSC and XRD. Release rates of those were increased according to the decrease of crystallinity. Also, NDs have different solubilities to dissolution media. Dissolution tests of NDs were examined in different media. NDs release rates were increased in high solubility.
In conclusion, we confirmed that solubility and crystallinity of drug influenced in release profile.
