Demeclocycline hydrochloride is an antibiotic isolated from a mutant strain of Streptomyces aureofaciens. It inhibits protein synthesis by binding with the 30S and possibly the 50S ribosomal subunit(s) of susceptible bacteria. Demeclocycline has antimicrobial activity against a wide range of gram-negative and gram-positive organisms. Demeclocycline is indicated in the treatment of infections caused by susceptible strains of the designated microorganisms. Demeclocycline is currently used to treat hyponatremia in patients with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Demeclocycline mainly attenuates hyponatremia in SIADH by reducing adenylate cyclase 5/6 expression and, consequently, cAMP generation, AQP2 gene transcription, and AQP2 abundance in the renal inner medulla, coinciding with a reduced vasopressin escape response in other collecting duct segments.

Skin and skin structure infections caused by Staphylococcus aureus. (Note: Tetracyclines, including Demeclocycline, are not the drugs of choice in the treatment of any type of staphylococcal infection).
When penicillin is contraindicated, tetracyclines, including Demeclocycline HCl, USP, are alternative drugs in the treatment of the following infections:
Uncomplicated urethritis in men due to Neisseria gonorrhoeae, and for the treatment of other uncomplicated gonococcal infections
Infections in women caused by Neisseria gonorrhoeae

In acute intestinal amebiasis, Demeclocycline HCl, USP may be a useful adjunct to amebicides.
In severe acne, Demeclocycline HCl, USP may be a useful adjunctive therapy.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Demeclocycline HCl tablets, USP and other antibacterial drugs, Demeclocycline HCl tablets, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. |

Sample Use Guides
Therapy should be continued for at least 24 to 48 hours after symptoms and fever have subsided.
Concomitant therapy: Absorption of tetracyclines is impaired by antacids containing aluminum, calcium, or magnesium, and by iron-containing preparations. Foods and some dairy products also interfere with absorption. Oral forms of tetracycline should be given at least 1 hour before or 2 hours after meals.
In patients with renal impairment: Tetracyclines should be used cautiously in patients with impaired renal function. Total dosage should be decreased by reduction of recommended individual doses and/or by extending time intervals between doses.
In patients with liver impairment: Tetracyclines should be used cautiously in patients with impaired liver function. Total dosage should be decreased by reduction of recommended individual doses and/or by extending time intervals between doses.
Administration of adequate amounts of fluid with the oral formulations of tetracyclines is recommended to wash down the drugs and reduce the risk of esophageal irritation and ulceration.
Adults: Usual daily dose – Four divided doses of 150 mg each or two divided doses of 300 mg each.
For pediatric patients above eight years of age: Usual daily dose, 7 to 13 mg per kg body weight per day, depending upon the severity of the disease, divided into two to four doses not to exceed adult dosage of 600 mg per day.
Gonorrhea patients sensitive to penicillin may be treated with demeclocycline administered as an initial oral dose of 600 mg followed by 300 mg every 12 hours for four days to a total of 3 grams.
