F. Acarturk et al., EVALUATION OF THE EFFECT OF LOW-MOLECULAR CHITOSAN ON THE SOLUBILITY AND DISSOLUTION CHARACTERISTICS OF SPIRONOLACTONE, Die Pharmazie, 48(8), 1993, pp. 605-607
The effect of the low-molecular chitosan on the solubility and dissolu
tion characteristics of spironolactone has been studied. Kneaded mixtu
res of spironolactone with low-molecular chitosan were prepared and th
eir in vitro dissolution behaviours were examined. The interaction of
spironolactone with low-molecular chitosan both in aqueous solution an
d in the solid state was examined by performing solubility analysis, p
owder X-ray diffractometry and differential scanning calorimetry measu
rements. It was found that low-molecular chitosan may be used for the
enhancement of the dissolution rate of spirono-lactone.
