Serevent is a type of asthma treatment called a reliever, and is manufactured by GlaxoSmithKline. It is different to other relievers as one dose has a long-acting effect on symptoms, lasting for over 12 hours in some cases. The product is supplied in two different devices: as an Evohaler, which contains a canister and is similar to a conventional inhaler; and an Accuhaler, which contains a powder.

  1. Most people in the UK are no stranger to asthma, and are aware of its effects. 
  2. Around 5.5 million people receive treatment for the condition, so its likely that even if you don’t have it, you know someone who does. 
  3. It affects the respiratory system, and is characterised by difficulty breathing, coughing, and wheezing. 
  4. These generally occur following exposure to a trigger, which is often an airborne irritant such as smoke, pollen, or dust particles; but cold air can exacerbate it too.
  5. Many people may also experience symptoms during exercise, or periods of emotional distress.

It isn’t fully understood why some people are more susceptible to asthma than others. Genetics are thought to play a part, as it has been found that those with a family history of the condition are more likely to get it. Environmental factors, such as persistent exposure to potential irritants during childhood, or a lack thereof, are also pointed to by experts as possible causes.

The catalyst for asthma symptoms is the immune system. It responds to these irritants by releasing a chemical which results in inflammation in the bronchi, which are the small pipes connecting the lungs to the trachea, or windpipe. When these become inflamed, the surrounding muscle walls tense up, and this narrows the airways. In some cases, inflammation can cause an increase in the production of phlegm, and this serves to further obstruct and hinder breathing.

  1. Salmeterol, which is the functioning component in Serevent, works by acting on beta-2 receptors. 
  2. This relaxes muscle walls in the affected area, and helps the narrowed airways to dilate, thus expediting smoother breathing patterns, and reducing symptoms.
  3. Getting the asthma treatment you need has never been easier. 
  4. Our online clinic service lets you have your case reviewed by a doctor, before having your medication dispensed and shipped to your door from a UK-based pharmacy.

It only takes a few minutes to fill in our health questionnaire. Once complete, our team will do the rest.
