| Description |
A synthetic tetracycline derivative with similar antimicrobial activity. Animal studies suggest that it may cause less tooth staining than other tetracyclines. It is used in some areas for the treatment of chloroquine-resistant falciparum malaria (malaria, falciparum). [PubChem] |

| Pharmacology |
| Indication |
Doxycycline is indicated for use in respiratory tract infections caused by Mycoplasma pneumoniae, Haemophilus influenzae, Streptococcus pneumoniae, Legionella spp., or Klebsiella spp. It is also used for prophylaxis of malaria. Doxycycline is indicated for a variety of bacterial infections, from Mycobacterium fortuitum and M. marinum, to susceptible E. coli and Brucella spp. It can be used as an alternative to treating plague, tetanus, Campylobacter fetus
|
| Pharmacodynamics |
Doxycycline, a long-acting tetracycline derived from oxytetracycline, is used to inhibit bacterial protein synthesis and treat non-gonococcal urethritis and cervicitis, exacerbations of bronchitis in patients with COPD, and adult periodontitis. |
| Mechanism of action |
Doxycycline, like minocycline, is lipophilic and can pass through the lipid bilayer of bacteria. Doxycycline reversibly binds to the 30 S ribosomal subunits and possibly the 50S ribosomal subunit(s), blocking the binding of aminoacyl tRNA to the mRNA and inhibiting bacterial protein synthesis. Doxycycline prevents the normal function of the apicoplast of Plasmodium falciparum, a malaria causing organism. |
| Absorption |
Completely absorbed following oral administration. |

| Toxicity |
Symptoms of overdose include anorexia, nausea, diarrhoea, glossitis, dysphagia, enterocolitis and inflammatory lesions (with monilial overgrowth) in the anogenital region, skin reactions such as maculopapular and erythematous rashes, exfoliative dermatitis, photosensitivity, hypersensitivity reactions such as urticaria, angioneurotic oedema, anaphylaxis, anaphyl-actoid purpura, pericarditis, and exacerbation of systemic lupus erythematosus, benign intracranial hypertension in adults disappearing on discontinuation of the medicine, haematologic abnormalities such as haemolytic anaemia, thrombocytopenia, neutropenia, and eosinophilia. LD50=262 mg/kg (I.P. in rat). |

Calcium salts such as calcium acetate may decrease the serum concentration of tetracycline derivatives such as doxycycline. In general, the coadministration of oral calcium salts and oral tetracycline derivatives should be avoided. Interactions may be able to be minimized by administering oral calcium preparations several hours before or after the dose of the oral tetracycline derivatives. Even with dose separation, therapy may still be compromised. Monitor for decreased therapeutic effect of oral tetracycline derivatives. |
| Calcium Chloride |
Calcium salts such as calcium chloride may decrease the serum concentration of tetracycline derivatives such as doxycycline. In general, the coadministration of oral calcium salts and oral tetracycline derivatives should be avoided. Interactions may be able to be minimized by administering oral calcium preparations several hours before or after the dose of the oral tetracycline derivatives. Even with dose separation, therapy may still be compromised. Monitor for decreased therapeutic effect of oral tetracycline derivatives. |

| Colesevelam |
Bile acid sequestrants such as colesevelam may decrease the absorption of Tetracycline Derivatives. Monitor for decreased therapeutic effects of tetracycline derivatives if coadministered with a bile acid sequestrant. If these agents are used concomitantly, separate doses 2 or more hours to minimize the interaction. The manufacturer of colesevelam suggests that drugs should be administered at least 1 hour before or 4 hours after colesevelam. |
