A kind of propranolol hydrochloride oral emulsion and preparation method thereof

Abstract

The invention relates to a propranolol hydrochloride oral administration emulsion for treating infantile hemangioma and a preparation method thereof. The oral administration emulsion is prepared from 0.25 to 40 parts by weight of propranolol hydrochloride, 70 to 300 parts by weight of oil phase, 22 to 200 parts by weight of emulsifiers, 15 to 101.5 parts by weight of co-emulsifiers and 352 to 1570 parts by weight of purified water. The propranolol hydrochloride oral administration emulsion provided by the invention solves the problem that no special oral administration preparation for treating infantile hemangioma exists in China at present. The propranolol hydrochloride oral administration emulsion provided by the invention overcomes the defect of a phenomenon of tablet and capsule taking difficulty due to infant pharyngeal narrowing. The propranolol hydrochloride is used as an effective ingredient to be uniformly dispersed in the emulsion; the administration dosage can be precisely mastered; the excessive treatment or insufficient treatment can be avoided.

Problems solved by technology

However, the commonly used preparations are tablets at present, and the dosage for infants and young children is very small. Usually, a tablet should be divided into multiple doses, and it is difficult to control the dosage accurately; It is inconvenient for infants and young children to take it, and has gastrointestinal reactions, which affects the curative effect; Chinese patent application CN102657697 discloses a kind of propranolol, clove basil oil nanoemulsion medicine and its preparation method. The surfactant and co-surfactant selected by the milk drug form a nanoemulsion preparation together with the drug, but the oral milk formed by the surfactant, co-surfactant and propranolol hydrochloride disclosed by the invention has poor stability. to be improved

At present, there is no propranolol oral preparation specially provided for infants in China, which cannot meet the current clinical needs
