Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/17640490

The inhibition of cyclic nucleotide Phosphodiesterase type 5 (PDE5) has been clinically validated as an effective treatment for erectile dysfunction. One of them is mirodenafil (formerly known as SK-3530) approved only in Korea. This drug was developed by SK Chemicals and marketed under the trade name Mvix.

Sample Use Guides

One tablet (Mirodenafil 50mg or 100mg) recommended dosing frequency is once per day. Taken orally approximately 60 minutes before sexual activity. Sexual stimulation is required for a response to treatment.
Route of Administration: Oral
The in vitro incubation of [14C]SK-3530 (MIRODENAFIL )with rat and human plasma samples resulted in high protein binding rates of more than 97%; binding was concentration-independent over the range tested (1–100 µmol/L), with no difference between the species show.
