Asthma Treatment: Its Not All About the Inhaler

Using Pills to Treat Asthma
Last week Trevors Pharmacy Feature Article focused on using a new pill for COPD. Traditionally we think of using inhalers as the best method to help us breathe if we have a respiratory disease such as COPD and Asthma. However; there are pills available to help us treat Asthma as well.
More than 300 hundred million people in the world suffer from Asthma and it is one of the most common chronic diseases in children. Since the 1980s and 1990s the prevalence of asthma has almost doubled. This may be due to increasing exposure to allergens and air pollutants. Although asthma is often diagnosed it is often not properly treated. It a major cause of hospitalization in children and causes over 300 deaths every year in Canada.
Inhalers are a very effective tool in preventing asthma symptoms and treating asthma attacks. They are very safe as well, with minimal side effects, even in children. An issue with inhalers is they are not all that convenient. They are fairly large and can be a nuisance to take to school or to work. They are not always the easiest to use, especially in young children or in the elderly. And sometimes even though inhalers are used properly, they do not prevent 100% of asthmatic symptoms.
For these reasons we should maybe look at oral medications in the tablet form a little closer. The pills we use for asthma are leukotriene receptor antagonists or LTRA tablets. Leuktorienes, very simply, are involved in asthmatic and allergic reactions to sustain inflammation. Inflammation and mucus production in asthma is exactly what we do not want because it makes it harder to breathe. The LTRA pills work to prevent the inflammation, which is what is causing the shortness of breath.
If you turn to the scientific studies it is very safe to conclude the pills are not better than inhalers. However, there seems to be more and more evidence emerging they may be just as good of a treatment option when measuring quality of life. Canadian asthma guidelines recommend the use of LTRAs when asthma is not controlled adequately by low doses of inhaled steroids. They are also recommended as an altenative in patients who cannot or will not use inhalers. In the united states LTRAs are recommended in first line use.
Two examples of LTRA pills available in Canada are Singulair (Montelukast) and Accolate (Zafirlukast). Accolate is taken twice daily and is recommended for use in adults and children over the age of 12. Singulair is a once daily pill which is available for children and adults. These medications have shown to be quite safe with few side effects.
These LTRA pills may be most effective for those who suffer from allergies and asthma. Almost 75% of asthmatic children also have documented allergies.
In my opinion treating asthma with pills is too often not considered. If you have asthma and your inhalers are not working it may be worth giving them a try. From my experience they seem to work well in Asthmatics who have a hard time controlling their breathing in the spring and fall seasons. It is also a good treatment option if the dose of steroids being inhaled per day is too high. Within a month of two of trying the medication the asthmatic should know whether it is effective or not.
If you are waking up at night from shortness of breath, have frequent coughing episodes or are unable to exercise because of you cannot breath, your asthma is not controlled.
