Abstract

The invention relates to naringin composition and a preparation thereof. The pharmaceutical composition is characterized by comprising naringin and levocetirizine hydrochloride, wherein preferably, the naringin is in a range of 27.5-275 mg, and the levocetirizine hydrochloride is in a range of 1.25-12.5 mg; the preferable mass ratio of the naringin to the levocetirizine hydrochloride is 20:1. Tests prove that the pharmaceutical composition has good curative effects on coughs and excessive phlegm caused by various reasons and the cough variant asthma, and the efficacy of the composition is obviously superior to the efficacy of the independently-used naringin or the independently-used levocetirizine hydrochloride.
