quinidine polygalacturonate

Use

Quinidine polygalacturonate(Cardioquin) is formed by reacting quinidine andpolygalacturonic acid in a hydroalcoholic medium. It containsthe equivalent of approximately 60% quinidine. Thissalt is only slightly ionized and slightly soluble in water, butstudies have shown that although equivalent doses of quinidinesulfate give higher peak blood levels earlier, a moreuniform and sustained blood level is achieved with the polygalacturonatesalt.
