Documented Uses

• Use (kg; approx.) in Germany (2009): >10
• Consumption (g per capita; approx.) in Germany (2009): 0.000122
• Synthesized from hydroquinone dimethyl ether by Friedel-Crafts acylation with chloroacetyl chloride, amination to the corresponding 2-aminoacetophenone, acylation at the amino function with chloroacetyl chloride, displacement of the chloro by the azido group and finally reduction with, e.g., sodium borohydride and catalytic hydrogenation (Pd/C).
• For the treatment of symptomatic orthostatic hypotension (OH).
• FDA proposed to withdraw approval of the drug midodrine hydrochloride, used to treat the low blood pressure condition, orthostatic hypotension, because required post-approval studies that verify the clinical benefit of the drug have not been done. To date, neither the original manufacturer nor any generic manufacturer has demonstrated the drug's clinical benefit, for example, by showing that use of the drug improved a patient's ability to perform life activities.
• ...used as a vasoconstrictor agent in the treatment of hypotension
