So asthma is a disease that is characterized by long -term inflammation of our ways and lungs that are affected.
00:11
So the symptoms of the disease do include constriction of the bronchioles in the lungs.
00:16
So this disease is caused by the combination of environmental as well as genetic related factors.
00:21
So certain drugs which act as beta blockers such as parabenol can trigger asthma.
00:28
So the abuteroa is a drug and when it's used to treat the disease such as asthma and chronic bronchitis and other.
00:36
Related diseases.
00:38
So it is a beta 2, adrogenetic antagonist.
00:46
This antagonist is a chemical substance that binds to a receptor and initiates a physiological process.
01:13
So the class of g proteins coupled receptors to the kerchicolamines binds are called adrenic receptors.
01:21
So the adrenic receptors tend to be classified into two types.
01:25
We have alpha and beta.
01:36
So the beta of further classified into b1, b2, b3.
01:45
The b1 is located mainly in the heart and kidneys.
01:49
B2 is located in the lungs...
