Vidalista Professional, like other formulations of Tadalafil, works by inhibiting the enzyme PDE5 (phosphodiesterase type 5), which plays a role in regulating blood flow in the penis. By doing so, it helps relax blood vessels and improve blood circulation, particularly in the penis, aiding in the treatment of erectile dysfunction (ED). However, its effects on blood pressure can also be significant, and this is something you need to be aware of. Effect of Vidalista Professional on Blood Pressure: Blood Pressure Lowering Effect: Tadalafil, the active ingredient in Vidalista Professional, relaxes the blood vessels, which may result in a mild decrease in blood pressure. This happens because it promotes the dilation (widening) of blood vessels, allowing for better circulation. The effect on blood pressure is usually mild and temporary. In healthy individuals, this slight drop in blood pressure is typically not a cause for concern. However, Vidalista Professional may cause a more significant drop in blood pressure in people who already have low blood pressure or those taking other blood pressure medications (especially nitrates or alpha-blockers). Interaction with Other Blood Pressure Medications: Nitrate medications: If you are taking nitrates (e.g., nitroglycerin or isosorbide), commonly prescribed for chest pain or angina, combining these with Vidalista Professional can cause a dangerous drop in blood pressure. This combination may lead to symptoms like dizziness, fainting, or even a heart attack or stroke in extreme cases. This is why the combination of PDE5 inhibitors like Tadalafil and nitrates is contraindicated and should be avoided. Alpha-blockers: If you're taking alpha-blockers for high blood pressure or prostate issues (e.g., Tamsulosin, Alfuzosin), Vidalista Professional may cause a further reduction in blood pressure, increasing the risk of dizziness or fainting.
