How does an inhaler work?

Rescue inhalers allow a person having an asthma attack to inhale their medication. When inhaled, the medication relaxes the muscles in the airways. This causes the airways to widen, reducing breathing difficulties. These types of medicines — bronchodilators — also help to open the airways by reducing the build-up of mucus.

It works by relaxing the muscles of the airways into the lungs, which makes it easier to breathe. Salbutamol comes in an inhaler (puffer). Salbutamol inhalers are usually blue. Salbutamol is sometimes given as tablets, capsules or syrup for people who cannot use an inhaler very well.

while the heads of the phospholipid structure attract water, the tails are hydrophobic. the model shows how the hydrophilic section folds around the fluid molecules to bring them into the cell so they don’t need to pass through the hydrophobic tails.
