what is the difference between diskus and hfa
Inhalers used as maintenance and prevention of acute attacks of asthma. Hfa is a pump used by people who have good coordination of the squeezing and inhaling process while the diskus doesn't require this. Medicine inhaled in the latter only requires the operator to suck in the powder without squeezing it. Good luck! Inhalers used as maintenance and prevention of acute attacks of asthma.
