Ventolin inhalers provide effective short-term relief from asthma and can prevent asthma symptoms from occurring after exercise. Ventolin is the most popular type of 'reliever' inhaler. The active ingredient is salbutamol, which will dilate the airways and ease breathing within five minutes. This is a very reliable inhaler for emergency asthma attacks.
Two forms of Ventolin inhaler are available: the Accuhaler and the Evohaler. The Accuhaler is a plastic device which contains a 60-blister strip. Each of these contains a 200mcg dosage that combines microfine salbutamol and lactose. The Evohaler is a pressurised metal device – each inhalation contains 100mcg of salbutamol. The propellant used in the Evohaler is HFA-134a, which is much less harmful to the environment than older propellants. Each of these treatments will provide effective relief after one or two doses.
Repeat supplies of Ventolin Accuhaler and Evohaler are available to buy from The Independent Pharmacy Online Doctor service, following a free consultation, to help control asthma in those who have been diagnosed by their GP.
There are two general types of medicine contained in inhalers. 'Preventers' usually contain corticosteroids. These are taken regularly – they reduce inflammation in the airways, controlling the chance of an asthma attack. Salbutamol-based inhalers, including Ventolin, are 'Relievers'. These are used when necessary, to ease asthma symptoms. Ventolin can also be used pre-emptively before you exercise or encounter an allergen. If your asthma is mild, you may only need a reliever inhaler. Ventolin can be used alongside a steroid-based preventer inhaler in serious cases.
Salbutamol is a type of medicine called a short-acting beta 2 agonist. When stimulated, the lungs' beta 2 receptors relax the muscles in the airways. This causes the airways to expand, which relieves asthma symptoms, such as coughing, wheezing, tightness of the chest and shortness of breath.
Asthma is thought to affect over 5 million people in the UK. It involves an inflammation of the bronchi, the tubes that connect the windpipe to the lungs. This swelling causes these airway passages to contract. It also increases the production of phlegm, which can further obstruct the airways. This leads to symptoms including coughing, wheezing, tightness of the chest and shortness of breath.
Though asthma is very common, people's experiences with symptoms will vary. Depending on the patient, asthma attacks may be triggered by allergens, infections, exercise, cold air, stress, or airborne chemicals such as in smoke. It is unknown why some people have this higher sensitivity to these irritants, though family history tends to affect one's likelihood of having the condition.
