Embodiment 1
[0038] A preparation method for ferrous sulfate enteric-coated dripping pills, which comprises the following steps:
[0039] (1) Preparation of ball core: weigh the composite matrix and FeSO at a weight ratio of 3:1 4 ·7H 2 O, the composite matrix is a mixture of PEG6000 and PEG4000, the weight ratio of PEG6000 and PEG4000 is 1:4, mix PEG6000 and PEG4000 and heat to 70°C, then mix the composite matrix with FeSO 4 ·7H 2 O melts at this temperature, fully stirs, mixes evenly, obtains the medicinal liquid, keeps warm for 20min, then draws the medicinal liquid and drips it into the condensate under the conditions of a drop distance of 2cm and a drip speed of 10 drops / min, forms a pill, and stands for half a day. Take it out after one hour, wipe off the condensate, and dry it; the temperature of the lower half of the condensate is 0°C, and the condensate is paraffin;
