What is the difference between Tadalafil tablets tablets and Viagra?
1. Duration: Tadalafil tablets tablets have a longer duration of action, with drug efficacy lasting up to 36 hours, while Viagra has a relatively short duration of action, usually only lasting 4-8 hours.
- Usage and Dosage: There are two main specifications of Xi'aili in the Chinese market, 20mg for on-demand use, and 5mg for once daily use. When taking as needed, the recommended dosage starts at 10mg and should be taken before sexual activity. If taking 10mg does not have a significant effect, 20mg can be taken. The dosage and frequency of use of Viagra are determined based on its specific drug form and doctor's advice.
- Contraindications: Clinical studies have shown that Tadalafil tablets tablets can enhance the antihypertensive effect of nitrate drugs, so patients who are taking any form of nitrate drugs are strictly prohibited from taking Tadalafil tablets tablets. For Viagra, its contraindications may vary depending on the specific form of medication and the patient's condition.
