What You Should Know About Drugs For Asthma

Anti cholinergic agents are drugs that keep the air passages open by reducing the tendency of the airways to close under the influence of acetylcholine, which has the opposite effect from adrenaline and tends to constrict them. By reducing the effect of acetylcholine, these drugs relax your airways for 8 to 12 hours. They are particularly useful for treating chronic asthma where anti inflammatory medication and beta agonists have not worked.
These bronchi dilating drugs work by making the mast cells in the lining of the lungs more stable, so preventing them from releasing the allergic chemicals and histamine. With fewer chemicals in the body the allergic reaction will be weaker. They are used as an alternative to beta2 agonists and are particularly good if you have exercise induced asthma.
Children tend to respond better to these drugs than adults. Your doctor may prescribe a drug with helophyte in it. This drug belongs to a group of chemicals called xanthenes, found in many plants, particularly tea and coffee. You may have found already that a strong cup of coffee prevents a mild asthma attack. These drugs are taken in tablet form and work by relaxing the muscles around the bronchi and unblocking the airways.
They are slowly released into your gut over 12 hours. In severe cases, aminophenol, other xanthenes, can be given as an infusion. Over the next few years, puffers will be replaced with new inhaler devices that do not contain CFC. The CFC does not harm you, but they do damage the earth's ozone layer. If you are being supplied with a new model, check with your doctor, nurse or pharmacist so that you know how it works.
