HOW TO TAKE THE ASTHMA MEDICINES
- Asthma medicines can be taken orally, by injections or can be breathed in (inhaled).
- Inhaled medicines are :
o Most commonly used world over.
o There are various methods of taking inhaled therapy (Inhaler, Rotahaler, Spacer, Mask, Accuhaler, Autohaler, Nebulizer).
o Inhaled medicines are not the last resort.
o It is not addictive as many people believe.
o The sooner one starts inhalational therapy the better.
o Bothquick relief and preventive medication can be taken through inhalational route.
- Oral medicines can be taken as tablets or syrups. But they take longer time to act and reach all over the body (via blood), where they are not needed.
Inhalational medicine can be given by various devices. Widely used devices are
- Metered Dose Inhaler (MDI) – Inhalers
- Dry Powder Inhaler (Rotahaler)
- Mask and a spacer
The choice of inhalational device has to be individualized for each patient by the treating physician.
The technique of using an MDI (inhaler) has to be learnt by the patient. It needs a bit of practice and some coordination on the part of the patient.
Use of a spacer, baby mask, Autohaler, Rotahaler and accuhaler can be a solution in those patients who finds it difficult to use an MDI (inhaler).
Nebulizers are electronic devices (compressed air generators) which are used to deliver asthma medication through inhalational route. It uses drugs in the form of a solution which is put in a nebulizing chamber and inhaled as a fine mist over 10 – 15 minutes. It can be used to deliver “reliever” medicine (Salbutamol) in an acute attack for instant relief. In young children it can be used to deliver “preventer” medicines (steroid solutions) for long term treatment. They are to be used judiciously and do not provide any superiority over other inhalational devices (if used properly) in the long run.
