Description

The present invention relates to the treatment of Emphysema by using Retinoic acid, its esters and the analogues. These compounds, when administered, either bucally, sublingually or by nebulizer, result in enhancing alveolar function or development; and thus offer great therapeutic and commercial potential in treating pulmonary diseases involving alveolar dysfunction, such as emphysema.

Applications

The present technology offers first non-surgical means to treat emphysema.

Stage of Development

Proof-of-concept demonstrated in mice.
