Abstract
Melts or ionic liquids containing amorphous propranolol, topical formulations and patches for transdermal drug delivery, and methods of making and using thereof are described herein. The melts or ionic liquids may be in a topical drug delivery formulation or patch to be applied to the skin. The drug delivery formulation or patch contains a sufficient amount of the amorphous propranolol to deliver a therapeutically effective amount of the amorphous propranolol to the patient in need of treatment, such as for the treatment or amelioration of infantile hemangioma. The formulations have a low viscosity and reduced skin irritation compared to the crystalline propranolol free base (PFB). The melts or ionic liquids can be formed by a salt metathesis reaction.
