Seoul:
High traces of Viagra and other drugs used to treat erectile dysfunction had been identified in Seoul’s wastewaters, and their presence in the urban region is anticipated to raise, South Korean researchers say.
The presence of the chemical substances utilized in the drugs — Phosphodiesterase-5 inhibitors (PDE-51) — had been higher on weekends and in sewage remedy facilities in Gangnam, which is home to nightclubs, bars and red-light spots, a new investigation showed.
“We estimated that the amount of PDE-5i consumption was 31 percent higher than in areas with fewer nightlife spots,” the researchers mentioned in the investigation paper carried by the Scientific Reports earlier this month.
Experts studied the presence of the chemical substances in the influent and effluent of two sewage remedy plants (STPs) in the South Korean capital as properly as the getting water bodies.
Their investigation indicated that the current sewage remedy plants had been “unable to handle” the amounts of the residual chemical substances.
“The PDE-5i in domestic wastewater were barely treated by the STPs and, eventually, discharged into the water environment,” the investigation paper mentioned.
“Considering the increasing market size, it is easily expected that more PDE-5i will be discharged in an urban area,” it added.
Around 23 % of South Korean males aged 30 to 39 are suffering from erectile dysfunction, research show, and the total PDE-5i sales of the best 20 Korean pharmaceutical corporations reached $133 million in 2019.
Due to their effectiveness in enhancing male sexual overall performance, the chemical is also usually illegally utilized as an ingredient of tonic medicines, eating plan supplements, and herbal dietary solutions in quite a few nations.
A current study identified PDE-5i and their analogues in 80 out of 188 foods and dietary supplements sold in Korea.
Around 322 million patients to endure from erectile dysfunction in 2025, with the prevalence of the disorder in Asia projected to jump from 87 million in 1995 to 200 million in 2025 due to ageing population.
