The aim of the study was to press a synergistic act of a formulation:
(1) enhancing the dissolution rate of a poorly water-soluble drug; (2)
controlling the release rate of the drug. There is still little
published research on such a formulation. The model drug used in the
current study
is isradipine (IS), a calcium channel blocker of the dihydropyridine
class. To fulfill the expected target, solid dispersion containing IS
was first
prepared with the carrier polyethylene glycol 6000 (PEG 6000) with the
melting method and then polyethylene oxide N-60K (PEO N-60K) was
utilized to induce drug release in a controlled manner. Physicochemical
properties of the solid dispersion and physical mixture were
character-ized by powder x-ray diffraction (PXRD) and Fourier transform
infrared (FTIR) spectroscopy to investigate the structural behavior of
drug and
IS-PEG interactions, respectively. Preparation of such a formulation not
only enhanced but also controlled the drug dissolution rate in both
simulated gastric (pH 1.2) and intestinal (pH 6.8) media. This result
should be a consideration for pharmaceutical scientists in maintaining
the
desired blood levels of drugs with narrow therapeutic fluctuation ranges
for extended periods of time after a single administration.
