COMPOSITIONS COMPRISING SALBUTAMOL SULPHATE

摘要

A surfactant-free pharmaceutical composition is described. The composition consists essentially of: (a) a drug component consisting of salbutamol sulphate; and (b) a propellant component consisting essentially of 1,1-difluoroethane (R-152a). A method for preparing the pharmaceutical composition is also described. The pharmaceutical composition can be delivered using a metered dose inhaler (MDI).
