The present invention discloses a
calcium dobesilate
dispersible tablet and a preparation method thereof. The
calcium dobesilate
dispersible tablet contains, by weight, a main
drug calcium dobesilate, and auxiliary materials such as 1-42% of cross-linked povidone, 0.5-42% of
microcrystalline cellulose, 2-44% of
lactose and 0.01-15% of
magnesium stearate. According to the present invention, a direct
powder tabletting method is adopted to prepare the
calcium dobesilate dispersible tablet; the method has characteristics of simple operation, time saving, reduction of times of
calcium dobesilate exposed to air and light, and reduction of
moisture absorption and light
instability; the prepared
calcium dobesilate dispersible tablet has a
smooth surface morphology, and can be completely disintegrated within 2 min and screened with a 2#
sieve, and the
dissolution rate of the prepared calcium dobesilate dispersible tablet in water and a dilute
hydrochloric acid solution within 5 min can achieve more than 90%; and the preparation method has characteristics of simple preparation process and time saving, and the prepared calcium dobesilate dispersible tablet has characteristics of
smooth surface, good dispersion uniformity and high
dissolution rate, and is suitable for industrial production.
