It is soluble in dehydrated alcohol, acetone, dichloromethane, and chloroform. ALVESCO 80 mcg and ALVESCO 160 mcg are pressurized, metered-dose aerosol units fitted with a dose indicator. ALVESCO is intended for oral inhalation only. Each unit contains a solution of ciclesonide in propellant HFA-134a (1,1,1,2 tetrafluoroethane) and ethanol. After priming, ALVESCO 80 mcg delivers 100 mcg from the valve and 80 mcg of ciclesonide from the actuator. ALVESCO 160 mcg delivers 200 mcg from the valve and 160 mcg of ciclesonide from the actuator. This product delivers 50 microliters (59.3 milligrams) of solution as a fine particle mist from the valve with each actuation. The actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between the actuation of the device and inspiration through the delivery system. ALVESCO should be “primed” by actuating 3 times prior to using the first dose from a new canister or when the inhaler has not been used for more than 10 days. Avoid spraying in the eyes or face while priming ALVESCO. Structural Formula
