Their mechanism of action is through the inhibition of protein synthesis, and the alteration of cytoplasmic membrane permeability within the susceptible organism. Doxycycline is more lipid-soluble than other tetracycline antibiotics and may reach higher levels in some of the difficult to penetrate areas, such as synovial fluid, central nervous system, prostate, and the eyes. Tetracycline antibiotics, including doxycycline, are effective against a broad spectrum of gram-negative and gram-positive bacteria, and wide variety of other organisms including Rickettsia, Spirochetes, Mycoplasma, Leptospira, Anaplasma, and Chlamydia.

Don’t infuse solutions more concentrated than 1 mg/ml. Use during last half of pregnancy and in children younger than age 8 may cause permanent discoloration of teeth, enamel defects, and bone growth retardation. for adults and 80 mg/kg/day divided q 8 hours for children is an option for completion of therapy after clinical improvement. Use cautiously in patients with impaired renal or hepatic function. Plasma half-life is 22 to 24 hours after multiple dosing in adults with normal renal function; 20 to 30 hours in patients with severe renal impairment. Contraindicated in patients hypersensitive to drug or other tetracyclines. Doxycycline is used to treat infections caused by bacteria, including pneumonia and other respiratory tract infections; certain infections of the skin or eye; infections of the lymphatic, intestinal, genital, and urinary systems; and certain other infections that are spread by ticks, lice, mites, infected animals, or contaminated food and water.

Doxycycline has the advantages of nearly complete absorption and long duration of action, and is therefore one of the most commonly used tetracyclines. As opposed to tetracycline, absorption of doxycycline is reported to be unaffected by food. The present study was carried out to assess the effect of standard breakfast on doxycycline absorption. Doxycycline–metal ion complexes are unstable at acid pH, therefore more doxycycline enters the duodenum for absorption compared with the earlier compounds.38 In addition, food has less effect on absorption than on absorption of earlier drugs10 with doxycycline serum concentrations being reduced by ∼20% by test meals compared with 50% for.
