Port St. Lucie, FL - Palo Alto Labs, 265 SW Port St. Lucie Blvd., Suite 252, Port St. Lucie, FL 34984, voluntarily recalled the company's supplement products sold under the name Aspire36 and Aspire Lite. Palo Alto Labs conducted the recall after being informed by representatives of the Food and Drug Administration that lab analysis found that the products contained Aildenafil in trace amounts and Dimethyl sildenafil thione (sulfoaildenafil) a purported analog of Sildenafil, an FDA- approved drug used as treatment for male Erectile Dysfunction (ED). Sulfoaildenafil is close in structure to Sildenafil and is expected to possess a similar pharmacological and adverse event profile. This may pose a threat to consumers because the analogue may interact with nitrates found in some prescription drugs (such as nitroglycerin) and may lower blood pressure20to dangerous levels. Consumers with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. ED is a common problem in men with these conditions, and consumers may seek these types of products to enhance sexual performance. Aspire36 and Aspire Lite are sold nationwide. The products are sold as a blister pack containing one liquid capsule or a bottle containing either three (3) or twelve (12) liquid capsules.
