Adrenergic sympathomimetic agent used in the treatment of orthostatic hypotension and cardiovascular syncope.
Oral or intravenous administration.

Since the last update we have not found any published data on its excretion in breast milk.

Its short half-life make transfer into breastmilk in significant quantities unlikely.
Its low oral bioavailability would make it difficult its passage to the infant’s plasma through breast milk except in premature babies and in the immediate neonatal period during which there may be greater intestinal permeability.

Trendelemburg position, may produce the same clinical improvement as (empiric) ethylephrine or propranolol therapy (Di Girolamo 1998).

There are very few bibiographical references and it is marketed in few countries.
