What is Regitine

PhentolamineThe Generic name of this drug
Treatment SummaryPhentolamine is a type of medication used to help lower high blood pressure, reduce symptoms related to pheochromocytoma, Raynaud's disease, clonidine withdrawal, and other conditions. It works by blocking signals from certain hormones in the body that cause blood vessels to constrict. It is sometimes used to treat impotence and peripheral vascular disease.

Effectiveness

How Regitine Affects PatientsPhentolamine is used to treat episodes of high blood pressure and sweating due to a condition called pheochromocytoma. It may be necessary to also take a beta-blocker if your heart rate gets too high. Phentolamine is a long-acting medication that relaxes the walls of blood vessels, resulting in lower blood pressure. It does this by blocking alpha receptors in certain parts of the body, which cause the muscle around the walls of the blood vessels to relax and widen. This allows more blood to flow, which lowers the pressure. It does not affect the parasympathetic system.
How Regitine works in the bodyPhentolamine works by blocking the receptors that normally cause muscles to tense and blood vessels to narrow. This makes the muscles relax and the blood vessels widen, which lowers blood pressure. Although phentolamine can block responses to adrenaline and similar hormones, it does not work as well on nerve endings. It also stimulates the beta adrenergic receptors in the heart, making it beat faster and increasing cardiac output.

Patient Q&A Section about regitine

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How do you give phentolamine for extravasation?

"Depending on the size of the extravasation, the nurse will need to bring 5 to 10 mg of phentolamine to the bedside. This will need to be reconstituted, and further diluted to 0.5 mg/mL in normal saline. Treatment of the extravasation will involve the nurse administering the phentolamine intradermally around the site of the extravasation."
