1.Is Sildenafil the same as tadalafil?
Cialis is the brand name for tadalafil and Viagra is the brand name for sildenafil. Both belong to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors.Tadalafil shares a similar efficacy and safety with sildenafil and significantly improves patients' sexual confidence. And Tadalafil (generic Cialis) has an advantage over Sildenafil in that it lasts a lot longer – up to 36 hours (compared with 4-5 hours for Sildenafil). Some men prefer this as it allows for more spontaneity.Sildenafil (Viagra) is by far the cheapest drug for ED and the one with the safety record. It is good for the occasional user but must be taken on an empty stomach. Tadalafil (Cialis) is expensive but lasts longer, making it useful if you have a more active and regular sex life.Furthermore, patients and their partners prefer tadalafil to sildenafil. Hence, tadalafil may be a better choice for ED treatment
2.How long does it take for Tadalafil to peak?
Peak plasma concentrations of Tadalafil/cialis are reached within 30 minutes to six hours (average time two hours) of a dose. Effects of 'as needed' Cialis last for up to 36 hours. The recommended starting dose for once daily Cialis for ED is 2.5mg; once daily Cialis for BPH, 5mg; and 'as needed' Cialis, 10mg.
3.Can you mix sildenafil and tadalafil?
Tadalafil should not be combined with Adcirca (another form of tadalafil) or other PDE5 inhibitors, for example, vardenafil (Levitra) or sildenafil (Viagra, Revatio).
