The scope of this paper focuses on Salbutamol as a drug and the mechanisms behind;
1) The drug function.
2) Development of drug resistance.
3) The clinical features of drug resistant individuals.
4) How to diagnose them.
5) Management of these patients.
Salbutamol resistance
Salbutamol is a beta 2 adrenergic receptor agonist that is short acting and used in the management of conditions that cause bronchospasms/bronchoconstriction. These conditions mainly include asthma and chronic obstructive pulmonary disease. Its systemic name is (RS)-4-[2-(tert-butylamino)-1-hydroxyethyl]-2-(hydroxymethyl) phenol. It has a half life of 1.6 hours, metabolized in the liver and exclusively excreted by the kidneys (1). …show more content…
Recovery, after therapy, is prolonged or absent even after maximum administration of effective dose. The most significant clinical feature appears in the deterioration of asthma and the subsequent exacerbation of the symptoms. Drug resistant asthma presents with (23);
