General Information about Combivent
Combivent metered dose inhaler (MDI) is a drug intended to treat asthma and COPD (chronic obstructive pulmonary disease). It contains a combination of two different types of bronchodilators - ipratropium and salbutamol. Combivent inhaler is used on a scheduled basis in the means of a symptoms prevention therapy. Although this medication does contain a fast acting bronchodilator, it is not recommended to use it to relieve acute symptoms such as a bronchospasm or asthma attack. As with any type of combination drug, the effective amount of salbutamol is reduced, limiting its potency as a reliever. Additionally, the other active ingredient, ipratropium bromide, is not designed to be used on an "as needed" basis - overuse of this drug may cause unexpected side effects or adverse reactions. With that said, it may be unwise to buy Combivent online to use as a rescue bronchodilator. Combivent inhaler is usually considered an alternative method of treatment in case initial therapy has proven to be ineffective or hazardous.
When and Why Combivent is Prescribed
A chronic obstructive pulmonary disease is a condition in which the bronchi - airway tubes that connect lungs to the trachea - become narrowed, making it harder to breathe and causing several symptoms that often include:
- Cough that often brings out sputum (mucus);
- Wheezing - a hissing or whistling sound can be heard when you breathe;
- Shortness of breath and oxygen retention, especially during physical activity;
- Feeling of pressure, tightness or extrusion inside the chest.
COPD has many causes (e.g. smoking, air pollution, persistent respiratory tract infections), and includes many different conditions (chronic bronchitis, emphysema). One thing is certain - this condition requires proper treatment to allow the person to have a symptom-free, comfortable life. Bronchodilators are often used in the treatment of COPD, both for the relief of acute symptoms as well as prevention of bronchospasms and other complications. The use of Combivent however, is not commonly implemented as means of a primary treatment; this medication is often used along with or after other medications if their application alone proves to be not efficient enough. You should consider to buy Combivent online only if you need to resume your current treatment or if you do not have enough medication to last through the whole round of treatment.
Combining Bronchodilators in Combivent
You may be aware that Salbutamol is a short-acting beta two agonist (bronchodilator) that is often used in "reliever" type inhalers to help with acute symptoms of asthma and COPD, such as a bronchospasm. In Combivent however, it is used along with a bronchodilator of a different type - an antimuscarinic ipratropium - to provide long lasting positive effects on the patient’s health, preventing future surfacing of symptoms.
These drugs may both belong to the same medication class, but their effect is quite different:
- Salbutamol stimulates certain receptors in the lungs (beta 2 receptors) which results in rapid relaxation of soft muscle tissue around the airways. The effect of their action is usually felt almost immediately - within 3 to 15 minutes that usually lasts for up to 6 hours.
- Ipratropium bromide works by blocking another group of receptors in the muscle tissue around the lungs and airways called muscarinic receptors. These receptors act as triggers to tighten airway muscles during a bronchospasm by reacting to a substance called acetylcholine, which is naturally present in the body. By blocking these receptors, acetylcholine can no longer trigger them to cause tightening of muscles, thus preventing the symptoms of a future bronchospasm.
