Vidalista CT 20 contains Tadalafil, a PDE5 inhibitor used to treat erectile dysfunction (ED). One of its effects is relaxing blood vessels, which can influence blood pressure. Here’s why and how: Mechanism of Blood Pressure Effects Vasodilation Tadalafil works by inhibiting the phosphodiesterase type 5 (PDE5) enzyme, which increases cyclic GMP levels in blood vessels. This relaxes smooth muscles in arteries, particularly in the penis, but also systemically, leading to widening of blood vessels. Lowered Vascular Resistance When blood vessels widen, blood flows more easily, which can reduce overall blood pressure. For most healthy men, this Vidalista CT 20 is mild and temporary. Interaction with Other Medications If combined with nitrates or certain antihypertensives, this effect can become dangerously pronounced, leading to dizziness, fainting, or severe hypotension. Who Is at Risk Men with pre-existing low blood pressure. Those on nitrate medications (for angina) or alpha-blockers (for prostate or blood pressure). Men with heart conditions should use caution. Key Takeaway Vidalista CT 20 can affect blood pressure because it relaxes blood vessels, which is part of how it improves erectile function. While usually mild, it can be risky in combination with other medications or pre-existing conditions.
