7. Frequently Asked Clinical Questions
Why does Vidalista work for 36 hours while Viagra only works for 4 hours?
Tadalafil possesses an elimination half-life of 17.5 hours compared to sildenafil's 3.8 hours, maintaining therapeutic plasma levels across 36 hours.
Can Tadalafil be used daily for prostate health (BPH)?
Yes. Daily low-dose Tadalafil 5mg relaxes smooth muscle tone in the bladder neck and prostate, significantly reducing urinary frequency and nocturia.
