What is a hydrofluoroalkane inhaler for chronic obstructive pulmonary disease (COPD)?

ANSWER

A hydrofluoroalkane inhaler is a handheld device that delivers a specific amount of medication in aerosol form, rather than as a pill or capsule. It has a pressurized canister inside a plastic case, with a mouthpiece attached. You press on the device while inhaling the COPD medication directly into your lungs. Its portability makes it easy to use anywhere, anytime. The inhaler uses a chemical propellant to push medication out.
