Abstract

The invention relates to a preparation method of cetirizine hydrochloride orally-taken drops, and belongs to the technical field of medicine and pharmacy. The cetirizine hydrochloride orally-taken drops are prepared from cetirizine hydrochloride bulk drug, a solvent, a correctant, a preservative, a pH-regulating agent and the like, and through quantified droppers, medicinal liquids are directly dripped into the oral cavity. The cetirizine hydrochloride orally-taken drops are an solution type preparation and have the following characteristics that 1, the quantified dropper is adopted and is screwed with a proportional valve, so that the medicine administration dosage is accurate, scientific and reasonable, and the shortcoming of administrating medicines by experience clinically is avoided;2, the drops can enable medicinal liquid to directly drip into the oral cavity of a patient, so that the medicine administration is convenient, and the cetirizine hydrochloride orally-taken drops areparticularly suitable for old people and patients suffering from dysphagia to use; 3, medicines are distributed in the state of molecules in liquid, so that after the medicine administration, the cetirizine hydrochloride orally-taken drops are rapid to absorb and take effect quickly; and 4, the cetirizine hydrochloride orally-taken drops are good in mouth feel, easy to accept by patients and goodin compliance.

Description
