Decongestants: Adrenergic Receptor Agonists

The video tutorial explains decongestants, drugs that alleviate nasal congestion by reducing blood flow to nasal mucosal membranes. It details the mechanism of action through A1 adrenergic receptor activation, leading to vasoconstriction. The tutorial covers direct and indirect decongestants, including adrenergic receptor agonists like phenylephrine and the role of exercise in reducing congestion. It also discusses the sympathomimetic drug ephedrine and its legal restrictions due to its potential misuse.
