What is Inhalation therapy ( Aerosol Therapy)?

Inhalation Therapy is a method to administer(deliver) drugs directly into the airway in patients with chronic( long-lasting) diseases of respiratory system like Asthma, COPD (Chronic Obstructive Pulmonary Disease) and Bronchiectasis.

In Inhalation Therapy (Aerosol Therapy), the medicine is made to float as mist in air(Aerosol) to be inhaled (breathed in) by the patient and deposited directly in the airway and lungs.

Why is Inhalation therapy Advised? ( Advantages of inhalation therapy).

In Inhalation Therapy the medicine reaches the airway directly, so the action is faster.

As the medicine is given directly to the airways, a small dose of the medicine is enough. So lesser side effects.

No gastritis as in oral medications and it is painless.

Inhalers come with Bronchodilators (Relievers) or Steroids (preventer/controllers) alone or in the combination of both.

Bronchodilators are used when the patient is breathless to relieve broncho constriction.

The combination of reliever and controller are used for prevention of bronchial asthma.
