The endothelium-dependent relaxation of the aortic rings precontracted with
phenylephrine was measured by vasorelaxation tests with acetylcholine.
The difference in these two studies did not compare the two drugs each other and ephedrine was used only in the two studies and dose used in the studies was different but
phenylephrine was more effective in the Tanaka et al.
A study comparing pupil responses to
phenylephrine 1% and hydroxyamphetamine 1% in 14 consecutive patients with OSP after previously confirming the diagnosis with cocaine 10%21 found that
phenylephrine 1% increased pupil size in postganglionic OSP by a mean of 2.
Relaxant responses are given as the percentage changes from
phenylephrine precontraction.
There's just one problem:
Phenylephrine also is useless in cold medicine, as consumers are discovering.
Phenylephrine was discontinued because the patient's systemic blood pressure had stabilized.

For those leading the war on methamphetamine, the critical difference between
phenylephrine and pseudoephedrine is that the latter is used to make meth.

The blood pressure increase was achieved using intravenous
