Product information

Description

Montelukast, from Accord, is an asthma medicine called a leukotriene receptor antagonist. It prevents the lungs from reacting to the natural compound leukotriene when they become aggravated by the triggers which can cause asthma symptoms. It is also used for the treatment of hay fever in asthmatics, and asthma attacks induced by exercise. 

  1. Used in addition to other asthma medications
  2. Tablet taken once a day
  3. Generic version of commonly prescribed treatment

Asthma is much more common than many people think, affecting over 5 million people in the UK. It is a long term respiratory disease where the airways of the lungs (bronchi) become inflamed due to certain outside factors, or triggers. When the bronchi come into contact with these triggers, they become narrow as the muscles around them contract and the lining of the airways swell. The airways are often made even narrower as a result of the excess of phlegm (mucus) which is generated.

Symptoms commonly attributed to asthma are coughing, wheezing, difficulty breathing properly and a tightness of the chest. If these symptoms intensify over several days or sooner, usually after exposure to a trigger, this is called an acute asthma exacerbation (or more commonly: an asthma attack). In some cases they can be very distressing, and particularly severe attacks will require urgent medical assistance.

Asthma triggers come in many forms, and are different for each person. Alcohol, smoking or breathing other people’s smoke, certain foods and stress are common causes, as well as allergens such as dust mites, pollen and hair from pets. Hormonal changes like puberty, pregnancy and the menopause can lead to the development or worsening of symptoms in women, and the increased breathing or changes in air temperature you undergo while exercising are also an instigator for some.

However, the condition is one which can be successfully managed through suitable medication and regular medical check ups. Montelukast is a preventer medicine used in conjunction with another preventer and reliever when the condition cannot be managed by one treatment alone. Montelukast stops the receptors in the lungs from reacting to leukotrienes, the substance created by the immune system when exposed to particular triggers. In doing this, the bronchi are prevented from responding in the manner that causes the symptoms of asthma.

You should contact your GP surgery if you require this medication. It is not available for purchase from our online pharmacy service.
