Demiclocycline
Indications
Demiclocycline is used for:
Used primarily to treat Lyme disease, acne, and bronchitis. Also indicated (but rarely used) to treat urinary tract infections, gum disease, malaria, and other bacterial infections such as gonorrhea and chlamydia. One of its other registered uses is the treatment of hyponatremia (low blood sodium concentration) due to the syndrome of inappropriate antidiuretic hormone (SIADH) where fluid restriction alone has been ineffective.

Mechanism of Action
Demeclocycline inhibits cell growth by inhibiting translation. It binds (reversibly) to the 30S and 50S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome, which impairs protein synthesis by bacteria. The binding is reversible in nature. The use in SIADH actually relies on a side-effect of tetracycline antibiotics; many may cause diabetes insipidus (dehydration due to the inability to concentrate urine). It is not completely understood why demeclocycline impairs the action of antidiuretic hormone, but it is thought that it blocks the binding of the hormone to its receptor.
