Normosang is a medication primarily used in the treatment of acute porphyria, a group of rare inherited or acquired disorders of certain enzymes in the heme biosynthesis pathway. It is an injectable solution that contains hemin, an iron-containing porphyrin, which is similar to the heme in hemoglobin. By supplementing the body with hemin, Normosang helps to suppress the overproduction of porphyrin precursors in the liver, thereby alleviating the symptoms associated with acute porphyria attacks. These symptoms can include severe abdominal pain, vomiting, hypertension, and neurological complications. Normosang is typically administered under the supervision of a healthcare professional in a hospital or specialized clinic setting, given its specific indications and the need for careful monitoring of patients receiving the treatment.
