Symptomatic treatment of idiopathic and rosacea-associated cutaneous flushing with propranolol
1Department of Dermatology, University of Texas Southwestern Medical School, Dallas, Texas 75390-9190, USA.
Abstract:
Flushing has been associated with medications, rosacea, menopause, carcinoid syndrome, pheochromocytoma, polycythemia, and mastocytosis, although it can occur without known cause. There are no known specific treatments available, but beta-blockers have suppressed flushing reactions in some patients, particularly when associated with anxiety. The medical histories and clinical characteristics of 9 patients with either idiopathic flushing or flushing associated with rosacea were reviewed. Eight patients experienced subjective improvement with propranolol therapy.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
