Embodiment 1
[0045] Compound cefaclor dry suspension, calculated in 1000 bags, its prescription composition:
[0046]
[0047] Taking the preparation of 1000 bags as an example, the preparation method of the above-mentioned compound cefaclor dry suspension is as follows:
[0048] Weigh the prescription amount of sodium saccharin and sunset yellow, add water and stir to dissolve, then add an appropriate amount of 95% ethanol, stir evenly for later use; pass sodium carboxymethyl cellulose and sucrose through an 80-mesh sieve for later use; mix sodium carboxymethyl cellulose and sucrose After mixing, add the above-mentioned ethanol-water solution containing sodium saccharin and sunset yellow to make a soft material, pass through a 30-mesh sieve to granulate, dry at 60°C, and pass the dry granules through a 30-mesh granule; mix the granules with cefaclor and bromine hydrochloride The same amount of Jixin is added and mixed, and finally orange essence is added, mixed evenly, and then packed ...
Embodiment 2
[0056] Compound cefaclor dry suspension, calculated in 1000 bags, its prescription composition:
[0057]
[0058] Weigh the prescription amount of sodium saccharin and sunset yellow, add water and stir to dissolve, then add an appropriate amount of 95% ethanol, stir evenly for later use; pass sodium carboxymethyl cellulose and sucrose through an 80-mesh sieve for later use; mix sodium carboxymethyl cellulose and sucrose After mixing, add the above-mentioned ethanol-water solution containing sodium saccharin and sunset yellow to make a soft material, pass through a 30-mesh sieve to granulate, dry at 60°C, and pass the dry granules through a 30-mesh granule; mix the granules with cefaclor and bromine hydrochloride Add the same amount of Jixin and mix it evenly, and finally add orange essence and micro-powdered silica gel, mix it evenly, and pack it separately (1g / bag).
Embodiment 3
[0060] Mix cefaclor (1 original drug), bromhexine hydrochloride (2 original drug) and related excipients in a certain proportion and then granulate them. The prepared granules are subjected to strong light (4500Lx), high temperature (40°C) Humidity (RH75%) influencing factors investigation, the results are shown in Table 4. It can be seen from Table 4 that the investigation results of the influencing factors of the original drug and various excipients show that its stability is good.
