Medically reviewed by Drugs. Last updated on Jan 1, Doxycycline is a broad-spectrum antibacterial synthetically derived from oxytetracycline. Doxycycline capsules USP, 75 mg, and mg contain Doxycycline monohydrate equivalent to 75 mg, and mg of Doxycycline for oral administration. Doxycycline has a high degree of lipid solubility and a low affinity for calcium binding. It is highly stable in normal human serum.

Doxycycline will not degrade into an epianhydro form. The capsules are printed with edible ink containing shellac, titanium dioxide, black iron oxide, brown iron oxide and potassium hydroxide for 75 mg and mg strengths. Tetracyclines are readily absorbed and are bound to plasma proteins in varying degrees. They are concentrated by the liver in the bile and excreted in the urine and feces at high concentrations in a biologically active form.

Doxycycline is virtually completely absorbed after oral administration. Following a mg dose of Doxycycline monohydrate, 24 normal adult volunteers averaged the following serum concentration values:. 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.

Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. Doxycycline has bacteriostatic activity against a broad range of Gram-positive and Gram-negative bacteria. Anaerobic Bacteria Clostridium species Fusobacterium fusiforme Propionibacterium acnes. Other Bacteria Nocardiae and other Actinomyces species Borrelia recurrentis Chlamydophila psittaci Chlamydia trachomatis Mycoplasma pneumoniae Rickettsiae Treponema pallidum Treponema pallidum subspecies pertenue Ureaplasma urealyticum.

Parasites Balantidium coli Entamoeba species. These reports should aid the physician in selecting the most effective antimicrobial. Quantitative methods are used to determine antimicrobial minimum inhibitory concentrations MICs. These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds.

Quantitative methods that require measurement of zone diameters can also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. The zone size should be determined using a standardized test method. The disk diffusion interpretive criteria are provided in Table 1.

For anaerobic bacteria, the susceptibility to Doxycycline can be determined by a standardized test method. A report of Susceptible S indicates that the antimicrobial is likely to inhibit growth of the microorganism if the antimicrobial drug reaches the webseries softhub usually achievable at the site of infection.

A report of Intermediate I indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug product is physiologically concentrated or in situations where high dosage rossi m92 ranch hand drug can be used.

This category also provides a buffer zone that prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of Resistant R indicates that the antimicrobial drug is not likely to inhibit growth of the microorganism if the antimicrobial drug reaches the concentrations usually achievable at the infection site; other therapy should be selected.

Standardized susceptibility test procedures require the use of laboratory controls to monitor and ensure the accuracy and precision of the supplies and reagents used in the assay, and the techniques of the individuals performing the test.

For the diffusion technique using the 30 mcg Doxycycline disk or 30 mcg tetracycline disk, the criteria noted in Table stm32 spi flash memory should be achieved.

To reduce the development of drug-resistant bacteria and maintain effectiveness of Doxycycline capsules, USP and other antibacterial drugs, Doxycycline capsules, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.
