Why Inhalers Are The Best Treatment For Asthma

Inhalers are the best treatment for asthma because it reaches the lung directly and causes minimal side effects. Read the below article to know more about it.

Asthma is a common chronic condition of the airways that is multifaceted and characterized by recurrent symptoms. It is a diverse condition that results from the interaction between a number of environmental and genetic factors.


Even though asthma is a chronic condition, it can be easily controlled. However, due to the numerous options of medication available in the market, it can get quite overwhelming to choose the best one. The effectiveness of a particular therapy for asthma depends on two factors –  the manner in which the drug is delivered and the dosage of the drug.


Topical Drug Delivery System


Targeted drug delivery is a mechanism that increases the efficacy of the drug. An example of this, are eye drops which used to treat irritation in the eyes. Via topical drug delivery, the eye drop solution directly targets the surface area of the eye and is hence, quite effective. The same way, targeted delivery of drug to the lungs would help in the treatment of asthma.


Inhalers are one of the most widely researched and prescribed topical drug delivery systems for asthma. Essentially, there are devices that allow you to breathe in the medication. Asthma inhalers deposit the drug directly to the targeted site i.e. the airways. Unlike oral medications like tablets and syrups, which must be absorbed in the gastrointestinal tract and need to travel through the bloodstream to various parts of the body before they reach the lungs, this type of delivery systems puts the drug exactly where it is required.


Reasons Why Inhalers Are The Best Treatment For Asthmatics


Over the past few decades, inhalation therapy has established itself as a valuable tool in the local therapy of respiratory conditions. Many international organisations such as the British Thoracic Society, Global Initiative For Asthma, and the National Asthma Council Australia recommend inhalers as the preferred form of medication for those diagnosed with asthma. There are numerous benefits of using an inhaler to asthmatics, such as:


1. Lower Quantities Of Drug Required


For a tablet to have the same effect as an inhaled medication, a larger dose would need to be prescribed. Since deliver a targeted dose directly to the air passages, the quantity required is significantly lower than that of any oral medication.


2. Lesser Side Effects


Inhalers have comparatively fewer or negligible side effects. The reason being that since they deliver the drug straight to the airways and very little is absorbed by the rest of the body. It only reaches the inner walls of the airways and the adverse effects are largely minimized, making it safe even for pregnant women and children to use. In comparison, oral steroids are used for shorter periods of time as compared to inhaled steroids due to the many side effects such as bloating, acidity, acne and increase in appetite.

3. Quicker Relief


The onset of action of the drug using inhalation therapy is much faster as compared to the results that oral medication . This is due to the fact that the drug is directly delivered to the lungs and does not need to be ingested and then absorbed into the bloodstream.


4. Ease of Usage


Inhalers are becoming increasingly popular due to the ease of use, small and compact sizing and the relative cost-effectiveness.


Due to their targeted delivery, quick mechanism of action and decreased side effects, it is safe to say that inhalers are the best treatment for asthmatics.
