New test detects Viagra hidden in supplements

Viagra single pack New test detects Viagra hidden in supplements Korean scientists have devised a sensitive, rapid and efficient test to detect the erectile dysfunction drug Viagra in dietary supplements, according to SeparationNow.com. The process involves combining solid-phase extraction with dispersive liquid-liquid microextraction. The result of this is liquid chromatography-UV detection method is that it sniffs out sildenafil almost as well as more sophisticated methods based on liquid chromatography-mass spectrometry (LC-MS).

“Up to now, LC-MS has proved to be the most effective method for detecting sildenafil, but Korean scientists led by Sung Won Kwon at Seoul National University wanted to try to develop an equally effective LC-UV detection method,” SeparationsNow.com reported. “For although UV detection is inherently less sensitive than MS, it is simpler and can work with a greater range of mobile phases, allowing LC with UV detection to separate and detect more analytes.”

The novel method is a mouthful, but its use is growing in necessity. Erectile dysfunction drugs like Viagra and Cialis, as well as unapproved analogues of those drugs, have been turning up in dietary supplements sold online and in retail stores in the U.S. and abroad as sexual enhancement products. These hidden ingredients are not generally listed on the labels of these products, meaning most people who use these supplements are unaware that they are taking an adulterated prescription medication.

Viagra side effects are can be serious and include heart attacks and strokes. The medication can also interact with medications that contain nitrates found in some prescription drugs such as nytroglicerin and may lower blood pressure to dangerous levels. Men with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. Even more concerning is that unapproved analogues of these erectile dysfunction drugs hidden in some dietary supplements have not been tested for safety and could lead to even more dangerous health consequences.
