Description and Uses
Demeclocycline lacks the C-6-methyl of tetracycline and is produced by a genetically altered strain of Streptomyces aureofaciens. Because it is a secondary alcohol, it is more chemically stable than tetracycline against dehydration. Food and milk co-consumption decrease absorption by half, although it is 60 to 80% absorbed by fasting adults. It is the tetracycline most highly associated with phototoxicity and has been shown to produce dose-dependent, reversible diabetes insipidus with extended use.
