Inhalers are portable, they are convenient and can provide immediate relief. Mild asthma may be recover if taking treatment with oral medications such as theophylline, zafirlukast.

Function of drugs used in an inhaler

The drug which are used inside an inhaler is very effective because this drugs goes straight into the airways. Therefore, if you take a smaller dose than tablet or liquid by mouth it's sufficient.

• Long -acting bronchodilators -  Bronchodilators do not prevent asthma attacks. This drug is never used for the emergency rescue from an acute attack of asthma.  
• Corticosteroids- This medicine you have to take for a long term to prevent asthma attacks, these medications include beclomethasone dipropionte, fluticasone, budesonide, triamcinolone, acetonide, flunisolide.
• Corticosteroid plus long-acting bronchodilator - This medication is work with combination of corticosteroid and a long-acting bronchodilator .

Devices of asthma inhaler

Here we are specifically saying asthma inhaler because inhaler used for many purpose. You can use inhaler for allergic problems & also use in case cold.

• Metered-dose inhalers - These inhalers use a chemical propellant to deliver the medication out of the inhaler. Squeezing the top of the canister converts the medication into a fine mist. The spacer acts as a holding chamber that keeps the medication from escaping into the air. It reduce the amount of medicine which may be deposited on the back of your throat. In this way medicine is reaches directly into your lungs.
• Dry powder inhalers - These types of inhaler do not have a gas propellant to squirt the drug out of a canister. You need to breathe in fairly hard to get the powder into your lungs. This is also use by adults and older children. Dry powder inhalers are not suitable for children under six as they often cannot breathe in hard enough to suck in all the powder.
• Nebulizer - Nebulizers are specially designed for those patients who are not able to use an inhaler, like infants, young children and those who are seriously ill. At very first step this device converting medication into a mist and delivering it through a mask that which you wear over your nose and mouth. It delivers a continuous medicated vapor to your lungs and its a very effective technique for moderate to severe patients in which inhalers alone work.
• Aerosol Inhalers - When the canister is pushed down, a proper dose of the medication is pushed out as you breathe it in. Pressurized metered dose inhaler is a canister filled with asthma medication.
• Puffers – Puffers means press and breathe. When you want to use puffers start to breathe in and, at the same time, press down on the canister and continue to breathe in deeply and steadily. Remove the puffer and hold your breath for 10 seconds. Puffers are easier to use with a spacer and are more effective this way.

Cost of asthma inhalers

The cost of the medications is the biggest problem . Asthmatic patient & their relatives are happy because they get fine solution as inhaler but at the same time they get nervous only because of heavy prices of asthma inhalers. But we hope that our doctors find alternate solution on it. The FDA, and several asthma supporting organizations try to ensure that these medicines will be available at cheaper costs than today's cost.
