Problems solved by technology

For such a variety of insomnia patients, the existing antihistamines not only have complicated prescriptions, but also fail to obtain sufficient effects when used as sleep-improving pharmaceutical compositions
[0005] Moreover, when users use existing antihistamines, the body's reaction to histamine is more obvious, and the vascular reaction to bronchi, nose, skin, and gastrointestinal tract is relatively strong, and certain side effects are arranged.
[0006] The existing preparation methods of antihistamine and sleep-promoting soft capsules are relatively complicated in technology, and the stability of the produced products is relatively poor, which cannot meet the demand

Abstract

The invention discloses a preparation method of a soft capsule capable of resisting histamine and promoting sleep. The preparation method is characterized by comprising the following steps of: A, preparing liquid gelatin, namely dissolving a plasticizer with water, then transferring into a glue tank, heating to reach 40 to 80 DEG C, adding gelatin, agitating at 60 to 80 DEG C to dissolve, agitating, pumping vacuum, and removing bubble to obtain the liquid gelatin; B, preparing contents, namely, mixing, agitating and dissolving polyethylene glycol and polyhydric alcohol, adding diphenhydramine hydrochloride, agitating to obtain suspension, then transferring to a mixing liquid tank, pumping vacuum, charging nitrogen to form nitrogen protection, heating to reach 50 to 90 DEG C to dissolve, and cooling to be below 40 DEG C after the diphenhydramine hydrochloride is dissolved, so as to obtain a content solution; and C, preparing the soft capsule, namely, respectively adding the liquid gelatin obtained in step A and the content medicine solution obtained in step B to a pelleting press, adjusting the packing volumes and thickness of gelatin coating, pelleting, drying, wiping and packing. The preparation method of the soft capsule capable of resisting histamine and promoting sleep is simple in process, convenient to manufacture, and high in product stability.
