Abstract

A method of cleaning a metered dose spray device, and a cleaning composition for such cleaning, to prevent the device from becoming clogged with medication. The method includes removing the aerosol can containing the medication from the actuator, placing an aerosol can containing a cleaning composition in the actuator, and dispensing the cleaning solution through the actuator. The residual medication is thereby removed from the actuator. A sufficiently small quantity of cleaning composition remains in the actuator so that the cleaning composition itself will not clog the actuator. Additionally, the cleaning composition is non-toxic, so that residual cleaning composition remaining in the actuator will not harm the user when a subsequent dose of medication is dispensed.

Description

RELATED APPLICATION [0001] This application is a Divisional of U.S. application Ser. No. 10 / 320,045, filed Dec. 16, 2002.[0002] The entire teachings of the above application are incorporated herein by reference. FIELD OF THE INVENTION [0003] The present invention relates to a method of cleaning actuators or metered dose dispensers used to dispense pharmaceutical compositions. The invention also relates to a composition to be used in cleaning actuators of metered dose dispensers. DESCRIPTION OF THE RELATED ART [0004] Metered dose spray devices are presently used to administer many different medications to the mouth and lungs, for example, asthma medication and nitroglycerin for treatment of heart disease. A typical metered dose spray device includes a container, for example, a can, for containing a solution or suspension of medication, a metering valve, and an actuator. The can will contain the medication to be dispensed, possibly a solvent for the medication, and a propellant. The p...
