Salbutamol Flashcards
What is Salbutamol?
Salbutamol is a Beta-2 selective agonist.
What are beta 2 receptors?
Beta 2 receptors are the predominant receptors on the bronchial smooth muscles.
Salbutamol ia considered a ____________ …….
Salbutamol is considered a SHORT ACTING BETA 2 AGONIST binding to the receptors.
What happens when the receptors are activated?
When they are activated, they cause an enzyme (Adenylyl Cyclase) to catalyse the conversion of ATP to a chemical messenger called cyclic AMP.
What does Cyclic AMP do?
It inhibits the inflammatory cells in the airways from releasing inflammtory mediators.
What is the benefit of cyclic AMP?
It ultimatley leads to the relaxation of bronchial smooth muscles, opening up the airways and improves breathing.
What is ATP?
The energy that drives many processes in living cells.
What is responsible for controlling the amount of airflow in our airways?
Smooth muscle cells.
