Phenylephrine - As Phenyephrine is basically an unstable chemically when in formulation, what is?

8 days ago

Phenylephrine is a selective α 1 -adrenergic receptor agonist used primarily as a decongestant, as an agent to dilate the pupil, and to increase blood pressure. Phenylephrine has recently been marketed as a substitute for pseudoephedrine (e.g., Sudafed (Original Formulation)), but there are claims that oral phenylephrine may be no more effective as a decongestant than a placebo.
