Embodiment 1

[0067] Mix 0.4wt% propranolol hydrochloride, 7wt% simethicone, and 8wt% egg yolk lecithin evenly, and high-speed shear (2000rpm, 20min) at 55°C to obtain an oil phase; 0.12wt% adenosine monophosphate Mix well with water, high-speed shear (3000rpm, 15min) at 55°C to obtain the water phase; mix the oil phase and water phase evenly, perform high-speed shear (4000rpm, 15min) at 55°C, and then homogenize under high pressure for 7 Second, during the homogenization process, the temperature is controlled at 55° C., and the pressure is controlled at 700 bar to obtain a propranolol hydrochloride nanoemulsion oral solution with an average particle diameter of 256 nm and a pH value of 5.8.

Embodiment 2

[0069] Mix 0.4wt% propranolol hydrochloride, 5wt% omega 3, and 4wt% egg yolk lecithin evenly, and high-speed shear (3000rpm, 15min) at 55°C to obtain an oil phase; 0.2wt% adenomonophosphate Mix glycosides and water evenly, and shear at 55°C at high speed (3000rpm, 15min) to obtain the water phase; mix the oil phase and water phase evenly, perform high-speed shearing at 55°C (4000rpm, 15min), and then homogenize under high pressure 6 times, during the homogenization process, the temperature was controlled at 55° C., and the pressure was controlled at 800 bar to obtain a propranolol hydrochloride nanoemulsion oral solution with an average particle size of 197 nm and a pH value of 5.7.

Embodiment 3

[0071] Mix 0.4wt% propranolol hydrochloride, 5wt% omega 3, and 4wt% egg yolk lecithin evenly, and high-speed shear (6000rpm, 10min) at 55°C to obtain an oil phase; 0.05wt% adenomonophosphate Glycosides and water were mixed evenly, and high-speed shearing (3000rpm, 15min) was performed at 55°C to obtain the water phase; the oil phase and water phase were mixed, high-speed shearing (3000rpm, 15min) was performed at 55°C, and then high-pressure homogenization was performed for 5 Second, during the homogenization process, the temperature is controlled at 55° C., and the pressure is controlled at 600 bar to obtain a propranolol hydrochloride nanoemulsion oral solution with an average particle size of 203 nm and a pH value of 5.6.

Abstract

The invention discloses a nano-emulsion oral solution containing propranolol or a salt thereof and a preparation method thereof, wherein the prescription of the nano-emulsion oral solution containingpropranolol or the salt thereof includes propranolol or the salt thereof, and pharmaceutically acceptable pharmaceutical excipients, wherein the pharmaceutical excipients include an oil phase medium,an emulsifier, a taste masking agent and purified water. The nano-emulsion oral solution containing propranolol or the salt thereof belongs to an oral taste masking preparation high in compliance, high in safety, good in stability and suitable for infants and young children to take for a long period of time, and conforms to clinical needs.

Description

technical field [0001] The invention relates to a nanoemulsion oral solution containing propranolol or a salt thereof and a preparation method thereof. Background technique [0002] Propranolol hydrochloride oral solution is used for the treatment of infantile hemangioma, and the general treatment cycle is about 6 months. Oral solution of propranolol hydrochloride in common dosage forms has obvious bitterness, and the problem of poor drug compliance of infants and young children in the long-term administration process is particularly prominent. Insist on long-term administration and affect the therapeutic effect. For example, if a large amount of additives such as correctives or sweeteners are added to the prescription of propranolol hydrochloride oral solution, although the bitter taste can be improved, these additives may have adverse effects on the development of brains and kidneys of infants during long-term medication. Serious adverse effects, not suitable for long-te...
