What we now about Regitine
Brand Name(s): Regitine
Generic Name Phentolamine Injection
What is phentolamine injection?
PHENTOLAMINE (Regitine®) treats a number of conditions. It helps to control the sweating and high blood pressure that occur with a disease called pheochromocytoma. Phentolamine can also help diagnose pheochromocytoma. Phentolamine can be used to treat tissue damage that occurs if certain intravenous (IV) medications accidentally leak from veins to tissues. Phentolamine increases blood flow, by expanding the blood vessels. Increase in blood flow to the penis can produce an erection in impotent men, although this is not an approved use. Generic phentolamine injections are available.
