Derma Sciences (OTCBB: DSCI), a manufacturer and marketer of advanced wound care products, announced that the FDA has given 510K clearance to the company's second dressing in the MEDIHONEY line. This dressing is indicated for use on wounds with light to moderate exudate, and - based on its hydrocolloidal properties - forms a gel when it comes into contact with wound fluid to assist in promoting a moist environment conducive to healing. Hydrocolloids are the most commonly used advanced wound care dressings, as most chronic wounds fall into the category of light to moderate exudate. In 2007 it is estimated that over $150 million in hydrocolloids will be sold in the US alone. The first MEDIHONEY dressing from Derma Sciences, cleared for use by the FDA in July 2007, is in an alginate base and is indicated for wounds with moderate to heavy levels of exudate.
