PRESCRIPTION DRUG
To reduce the development of drug-resistant bacteria and maintain effectiveness of Doxycycline Hyclate Tablets, USP and other antibacterial drugs, Doxycycline Hyclate 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. Doxycycline is indicated for the treatment of the following infections: - Rocky Mountain spotted fever, typhus fever and the typhus group, Q fever, rickettsialpox, and tick fevers caused by Rickettsiae. - Respiratory tract infections caused by Mycoplasma pneumoniae . - Lymphogranuloma venereum caused by Chlamydia trachomatis . - Psittacosis (ornithosis) caused by Chlamydophila psi

Abbreviated New Drug Application
DOXYCYCLINE- DOXYCYCLINE HYCLATE TABLET, COATED BLENHEIM PHARMACAL, INC. ---------- DOXYCYCLINE HYCLATE TABLETS, USP REV. 11/14 RX ONLY To reduce the development of drug-resistant bacteria and maintain the effectiveness of doxycycline hyclate tablets and other antibacterial drugs, doxycycline hyclate tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. CLINICAL PHARMACOLOGY Tetracyclines are readily absorbed and are bound to plasma proteins in varying degree. They are concentrated by the liver in the bile, and excreted in the urine and feces at high concentrations and in a biologically active form. Doxycycline is virtually completely absorbed after oral administration. Following a 200 mg dose, normal adult volunteers averaged peak serum levels of 2.6 mcg/mL of doxycycline at 2 hours decreasing to 1.45 mcg/mL at 24 hours. Excretion of doxycycline by the kidney is about 40% per 72 hours in individuals with normal function (creatinine clearance about 75 mL/min). This percentage excretion may fall as low as 1 to 5% per 72 hours in individuals with severe renal insufficiency (creatinine clearance below 10 mL/min). Studies have shown no significant difference in serum half-life of doxycycline (range 18 to 22 hours) in individuals with normal and severely impaired renal function. Hemodialysis does not alter serum half-life. Results of animal studies indicate that tetracyclines cross the placenta and are found in fetal tissues. MICROBIOLOGY Doxycycline inhibits bacterial protein synthesis by binding the 30S ribosomal subunit. Doxycycline has bacteriostatic activity against a broad range of Gram-positive and Gram-negative bacteria. Cross resistance with other tetracyclines is common. Doxycycline has been shown to be active against most isolates of the following microorganisms, both _in vitro_ and in clinical infections as described in the INDICATIONS AND USAGE section of the package insert for doxycycline hyclate tablets. _GRAM-NEGATIVE BACTERIA _ _Acin 전체 문서 읽기
