General Information

Nobody knows exactly how Ergoloid Mesylates produces its effect, but it improves the supply of blood to the brain in test animals and reduces heart rate and muscle tone in blood vessels. Some studies have shown the drug to be very effective in relieving mild symptoms of mental impairment, while others have found it to be only moderately effective. It has been most beneficial in patients whose symptoms are due to the effects of high blood pressure in the brain. This medicine should not be used for any condition that is treatable with another medicine or that may be reversible. Your doctor should check periodically to be sure that this medicine is still needed and that it is working for you. It must be taken for 6 months before your doctor will be able to decide if it is working or not.
