Abstract

A lozenge, for release of zinc 2+ ions in the oral cavity of a human comprises 0.5 to 5 % by wt of zinc lactate in combination with a pharmaceutically acceptable carrier or sugar. In the presence of human saliva, said lozenge releases at least 0.2 mg of zinc 2+ ions per ml of saliva with a pleasant taste and aftertaste. The lozenges may be used as medicaments or nutritional supplements for reducing the symptoms and/or duration of the common cold, rhinitis and/or sinusitis.
