概要

 This episode explores tadalafil (Cialis) as a potential longevity drug, though no randomized human trials prove it extends lifespan. Cialis works by blocking PDE5, enhancing nitric oxide signaling, and improving blood flow through vasodilation. Originally approved for pulmonary hypertension, it's also used for erectile dysfunction and BPH. Its 36-hour half-life makes it superior to Viagra for continuous longevity effects. The host frames vascular aging and endothelial dysfunction as key drivers of age-related diseases (heart disease, stroke, dementia, kidney disease). Observational data shows Cialis users have 44% lower mortality, fewer cardiovascular events, reduced dementia risk, and lower mortality in diabetics. Additional benefits include improved cardiac function, reduced infarct size, arrhythmia suppression, and regression of left ventricular hypertrophy. A 2024 meta-analysis found it lowers hemoglobin A1C, possibly via improved microvascular perfusion, insulin sensitivity, and mitochondrial function. Cialis crosses the blood-brain barrier and may improve neurovascular coupling and hippocampal plasticity, potentially benefiting those with or at risk of dementia. Safety is generally good with long-term daily use (2.5–5 mg), though cautions include avoiding use with nitrates, low blood pressure, or certain retinal disorders. Common side effects are headache, nasal congestion, and acid reflux. The host recommends consulting a doctor and references potential synergy with telmisartan.
