Itraconazole capsules are an antifungal medicine. They treat fungal infections in your body.
Vasopressin injection helps raise blood pressure in adults with shock. It is used when fluids and other medicines don't work well enough.
Itraconazole treats fungal infections like blastomycosis, histoplasmosis, and aspergillosis. It can help both people with healthy immune systems and those with weakened immune systems. It also treats onychomycosis, a fungal infection of the toenails or fingernails.
Vasopressin injection is used to increase blood pressure. It is for adults who have vasodilatory shock. This is when blood vessels relax too much, causing low blood pressure. It is used when fluids and other medicines called catecholamines are not enough to raise blood pressure.
Itraconazole stops fungi from growing. It does this by interfering with the production of a substance fungi need to build their cell membranes. This eventually kills the fungus and clears the infection.
Vasopressin is a hormone that makes blood vessels get tighter. This helps to increase blood pressure. It can also affect how your kidneys handle water.
