First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a blood test measuring the 'atherogenic index' can predict how well the drug tadalafil works for men with erectile dysfunction caused by blood vessel problems. Researchers will give 132 men tadalafil daily for one month and compare their symptom scores before and after treatment. The goal is to see if this simple blood marker can help personalize treatment.
