3. Phenylenhrine Hydrochloride

Ophthalmology, 1980
Phenylephrine hydrochloride is a potent, effective, relatively safe drug with few ocular side effects. Side effects from topical instillation are uncommon but include severe systemic cardiovascular effects with elevated blood pressure and stroke. Ten percent phenylephrine should be used with caution in patients with known cardiac disease, hypertension,

PHENYLEPHRINE HYDROCHLORIDE IN PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA

Journal of the American Medical Association, 1955
Phenylephrine (Neo-Synephrine) hydrochloride was first suggested as an effective drug in the treatment of paroxysmal supraventricular tachycardia by Youmans and his group in 1947. Since this time others have mentioned its use and at the same time suggested that the drug was relatively innocuous in the absence of heart disease.

USE OF PHENYLEPHRINE HYDROCHLORIDE (NEO-SYNEPHRINE HYDROCHLORIDE(R)) IN OPHTHALMOLOGY

Archives of Ophthalmology, 1949
THE FIRST studies on the ocular use of phenylephrine hydrochloride (neo-synephrine hydrochloride®) were begun in 1933 and reported in 1936.1Since then, extensive clinical experiences with this drug have accumulated with additional observations. The object of this article is to review these data, bringing them up to date.
