Drugs to improve blood flow for people who have poor blood circulation in the veins of their legs. Background. Insufficient blood circulation in the veins of the legs might be caused by genetic factors, may occur after trauma, or may result from a blood clot. Poor movement of blood up the legs may cause swelling and puffiness, feelings of heaviness, tingling, cramps, pain, varicose veins and changes in skin pigmentation. If severe insufficient blood circulation occurs, ulcers and skin wasting can develop. Drugs such as natural flavonoids extracted from plants and similar synthetic products may improve blood circulation. These drugs are known collectively as venoactive drugs or phlebotonics.
Medicines to Treat Kidney Disease. People with kidney disease often take medicines to lower blood pressure, control blood glucose, and lower blood cholesterol. Two types of blood pressure medicines - ACE inhibitors and ARBs - may slow kidney disease and delay kidney failure, even in people who don't have high blood pressure. The most important step you can take to treat kidney disease is to control your blood pressure. Many people need to take two or more medicines for their blood pressure, often including a diuretic (water pill). These medicines may work better if you limit your salt intake.
