Medicine For Bronchoconstriction
Stop breathing: Bronchoconstriction, or narrowing of the airways due to swelling and/or spasm, decreases airflow into the lungs, and increases the effort needed to get that air in. This combination of stresses lowers the oxygen level, and if severe enough, a person can become weak, confused, collapse from exhaustion or even stop breathing altogether. This is how people can even die from an asthma attack. ...Read more

Tightened airways: Bronchoconstriction is narrowing of the air passages between the windpipe and the air sacs of the lungs, and is generally caused by swelling and spasm, which can be caused by infection, asthma, allergies, chemical irritation (smoke, smog or fumes), or a combination of factors. Acute means that a problem started suddenly or is only there for a short while (as opposed to chronic, all the time). ...Read more
What are some of the cells and inflammatory mediators involved in non-asthmatic exercise induced bronchoconstriction?
Pressure.: Long story...essentially, the pressure pushing upon the airways with expiration causes the airways to close upon themselves, causing air trapping which is one of the hallmarks of COPD and the other obstructive lung diseases. ...Read more
Negative pressure: When you breathe in, your chest wall and diaphragm expand and create decreased pressure in your lungs. Because the bronchoconstriction is also inside your lungs, the negative pressure causes the airway to expand as well, and air flows in easily. When you breathe out, the chest wall and diaphragm relax, and pressure in the lungs increases. This snaps the airways closed again, like a valve. ...Read more
Why is breathing in during inspiration not affected by bronchoconstriction (asthma/copd)? I need some advice.
Bronchoconstriction: Lung disease is defined as either restricted or obstructed. Bronchoconstriction is, by definition, an obstructed condition. Obstructed diseases limit the ability to exhale air out of the lungs. Asthma and COPD are examples of diseases that lead to airway obstruction, where exhalation is affected, not inhalation. ...Read more
Bronchoconstriction (asthma/copd) affects breathing out during expiration, but not breathing in during inspiration, how come?
This is a fancy term of when airway pressure is more on the outside of your airways and collapses as you exhale. This pressure difference happens at different stages of exhalation in copd.
With asthma there is narrowing of your airways from inflammation so this constricts the diameter and makes this worse. All due to airway pressure and "equal pressure point". Hope this helps! ...Read more
I have bronchoconstriction (asthma/copd) affects breathing out during expiration, but not breathing in during inspiration. Why, what to do?
Typical symptoms: This is a common symptoms for those with airway obstruction be it from asthma or copd. You need to get an assessment to determine what kind of medications may relieve your symptoms. Inhaled steroid, inhaled bronchodilator, and inhaled anticholinergic are the most common drugs used in your condition. Most of these drugs need to be used regularly. ...Read more
Does anticholinergic or antihistamine alone relieve bronchoconstriction in asthma? Will doctors prescribe one or another or both with beta 2 agonist?
Anticholinergic: Anticholinergic but not the usual doses of antihistamine relieves bronchoconstriction in some people. It may be used as a combination with a beta 2 agonist as in the case of combivent (albuterol and ipratropium). However persistent asthma should be treated with a controller drug such as inhaled steroid and/or a leukotriene blocker. Using just beta agonist alone on a regular basis may actually make your asthma worse. ...Read more
Having a broncho-constriction everyday at night with cough but no sputum, started two weeks ago after an upper respiratory tract infection, what to do?
Lung function test:
There can be prolonged inflammation in the lung following an infection. Your symptoms indicate that you may have post viral broncho constriction.
Your physician may order a pulmonary function test to determine if you have reactivity of the airway.
I would suggest a flu vaccine if there are no reasons in your medical history not to obtain one. ...Read more

Many of them: This is not an easy answer since there are many drugs categorized as unsafe. The american porphyria foundation has good resources on drug safety: http://www. Porphyriafoundation. Com/testing-and-treatment/drug-safety-in-acute-porphyria. Just because a drug may be listed as unsafe doesn't mean it's unsafe for everyone. However, it's important to use caution with any drug that is potentially unsafe. ...Read more
