A solid sustained release matrix composition for release of zinc 2+ ions in the oral cavity of a human comprises zinc lactate in combination with a pharmaceutically acceptable carrier, which contains a taste-masking agent such as a sugar. In the presence of human saliva, said composition releases at least 0.2 mg of zinc 2+ ions per ml of saliva with a pleasant taste and aftertaste. The compositions may be used as medicaments or nutritional supplements for reducing the symptoms and/or duration of the common cold, rhinitis and/or sinusitis. The taste-masking was either sucrose plus glucose or lactitol plus maltitol. |
