How does Aironyl work?
Terbutaline sulphate belongs to a group of medicines called short-acting beta 2 agonists. It works by acting on receptors in the lungs, called beta 2 receptors. Stimulation of these receptors causes the muscles in the airways to relax, and this allows the airways to open.
In conditions where there is narrowing of the airways, such as asthma, emphysema and bronchitis, it is difficult for air to get in and out of the lungs. By opening the airways, terbutaline makes it easier to breath.
Terbutaline is most commonly taken using an inhaler device. Inhaling the medicine allows it to act directly in the lungs where it is needed most. It also reduces the potential for side effects occurring in other parts of the body, as the amount absorbed into the blood through the lungs is lower than if it is taken by mouth. Terbutaline when used as an inhaler is known as a reliever. This is because it works very quickly to relieve asthma attacks or shortness of breath. Terbutaline inhalers can also be used to open the airways shortly before exercising. Terbutaline tablets are sometimes prescribed if inhaled terbutaline is being used frequently to relieve shortness of breath. The tablets are taken regularly to help keep the airways open all the time and reduce the need for the inhaler.

Why we use Aironyl?
  • Asthma
  • Breathing difficulties due to a narrowing of the airways (bronchospasm)
  • Chronic obstructive pulmonary disease
Use with caution in:
  • Diabetes
  • Heart failure
  • Thyrotoxicosisis also called Hyperthyroidism is the term for overactive tissue within the thyroid gland, resulting in overproduction and thus an excess of circulating free thyroid hormones: thyroxine (T4), triiodothyronine (T3), or both.'

Not to be used in
Heart disease characterized by thickening of the internal heart muscle (hypertrophic cardiomyopathy)
This medicine should not be used if you are allergic to one or any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy. If you feel you have experienced an allergic reaction, stop using this medicine and inform your doctor or pharmacist immediately.

Pregnancy and Breastfeeding
Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
• This medicine should be used with caution during the first trimester of pregnancy.
• The medicine passes into the breast milk, but at normal doses it is unlikely to harm the baby. Discuss with your doctor.

Drug interactions:
Beta-blockers such as atenolol, propranolol or timolol should not generally be taken with this medicine. This is because beta-blockers have an opposite action to terbutaline, and can cause the airways to narrow. This can result in breathing difficulties for people with asthma or chronic obstructive airways disease.
Eye drops containing beta-blockers should also be avoided.
Terbutaline can potentially cause a serious decrease in the levels of potassium in the blood (hypokalaemia), which may result in increased risk of abnormal heart rhythms (arrhythmias) if hypokalaemia occurs while taking this medicine.

This effect can be increased by the following medicines:
  • Xanthine derivates such as theophylline
  • Corticosteroids such as beclometasone and prednisolone
  • Diuretics such as bendrofluazide and frusemide

There may be an increased risk of side effects if this medicine is taken with other sympathomimetic medicines, such as the following:
Other beta 2 agonists: e.g. salbutamol, salmeterol
Decongestants: e.g. Ephedrine, pseudoephedrine, phenylephrine - adrenaline - dopamine - amfetamines.
