The introduction of the oral phosphodiesterase type 5 (PDE5) inhibitor sildenafil citrate (trade name: Viagra) opened a new chapter in the history of erectile dysfunction (ED) treatment. Since Sildenafil citrate was approved by the US Food and Drug Administration (FDA) in March 1998, the research on PDE5 inhibitors represented by Sildenafil citrate has made great progress. With the expiration of sildenafil's original research patent, it is the goal of synthesis workers to prepare high purity sildenafil citrate stably and efficiently and suitable for industrial production.
