Vidalista 20 is the commonly used medication used to treat male sexual disorders like erectile dysfunction (ED). When using Tadalafil, you need to take care not to mix it with nitrates in any form. Both Tadalafil and nitrates are known to reduce blood pressure. When they are combined, you can suffer a severe drop in blood pressure which can kill you. If you have to use both of these drugs, ensure the doses are 48 hours apart. Some of the drugs in this category are used to treat angina, which is commonly referred to as chest pain.
