Hydroxyamphetamine is a derivative of amphetamines. Hydroxyamphetamine is intended mainly as local eye drops for diagnostic purposes. It is indirect sympathomimetic agent which cause dilation of the eye pupil before diagnostic test. Among the minor side effects from its use are: change in color vision, difficulty seeing at night, dry mouth, headache, increased sensitivity of eyes to sunlight, muscle stiffness or tightness and temporary stinging in the eyes. The main use of hydroxyamphetamines as eye drops is the diagnosis of Horner's syndrome which is characterized by nerve lesions. Hydroxyamphetamine hydrobromide is a component of FDA approved brand drug - Paremyd sterile ophthalmic solution (Hydroxyamphetamine hydrobromide, USP 1.0%, Tropicamide, USP 0.25%). Hydroxyamphetamine is an indirect-acting sympathomimetic, while tropicamide acts as a parasympatholytic.

CNS Activity

Curator's Comment: The blood-brain barrier is permutle to Hydroxyamphetamine in rats. Hydroxyamphetamine is CNS active

Originator

Curator's Comment: Abbot and Henry introduced the use of paredrine (hydroxyamphetamine).

Sample Use Guides

Mydriasis: Ophthalmic: Instill 1 to 2 drops into conjunctival sac(s)
Route of Administration: Topical
SH-SY5Y neurons were incubated with Hydroxyamphetamine (concentration range 0-10mM) for 24 or 48h, and the viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and lactate dehydrogenase (LDH) leakage assays.. For Hydroxyamphetamine the TC50 was not reached in the tested concentration range. Hydroxyamphetamine at 8.00mM originated few late apoptotic cells
