Tetracycline Usage And Synthesis
Chemical PropertiesCrystalline Solid
Chemical PropertiesTetracycline trihydrate is a white crystalline substance.
Usesantibactierial
Usesantibacterial, antiamebic, antirickettsial
UsesTetracycline is a linear, tetracyclic, broad spectrum antibiotic first prepared chemically by dechlorination of chlortetracycline and subsequently isolated from several Streptomyces species. Tetracycline has broad spectrum antibacterial and antiprotozoan activity, and acts by binding to the 30S and 50S ribosomal subunits blocking protein synthesis. Tetracycline is a pigment and, like many pigments, is degraded by light, oxygen, trace metal ions and pH variations. The purity of tetracycline is often variable, with significant levels of degradation products.
UsesTetracycline is a broad spectrum polyketide antibiotic. It is used clinically to treat bacterial infections such as Rocky Mountain spotted fever, typhus fever, tick fevers, Q fever, and Brill-Zinsser disease. It is used to treat upper respiratory infections and acne. It is used to study multidrug resistance as well as potential side effects such as acute pancreatitis.

World Health Organization (WHO)The first tetracycline antibiotic, chlortetracycline, was introduced in 1948 and subsequently several semisynthetic derivatives have been used as antibacterial, antiamoebic and antirickettsial agents. All tetracyclines accumulate in the developing bones and teeth of the foetus and young children which can result in retarded bone growth and dental staining. Preparations intended specifically for children have been withdrawn in some countries, whereas in others warnings are required on the label advising against administration of tetracyclines to young children and pregnant women. Non-paediatric dosage forms of tetracycline remain in the WHO Model List of Essential Drugs.
Antimicrobial activityIt is also active against V. cholerae, chlamydiae, rickettsiae and spirochetes.
General DescriptionChemical studies on chlortetracycline revealed that controlledcatalytic hydrogenolysis selectively removed the 7-chloro atom and so produced tetracycline (Achromycin,Cyclopar, Panmycin, Tetracyn). This process was patentedby Conover in 1955. Later, tetracycline was obtainedfrom fermentations of Streptomyces spp., but the commercialsupply still chiefly depends on hydrogenolysis of chlortetracycline.
Tetracycline is 4-dimethyl amino-1,4,4a,5,5a,6,11,12aoctahydro-3,6,10,12,12a-pentahydroxy-6-methyl-1,11-dioxo-2-naphthacenecarboxamide. It is a bright yellow, crystallinesalt that is stable in air but darkens on exposure tostrong sunlight. Tetracycline is stable in acid solutions witha pH above 2. It is somewhat more stable in alkaline solutionsthan chlortetracycline, but like those of the other tetracyclines,such solutions rapidly lose potency. One gram ofthe base requires 2,500 mL of water and 50 mL of alcohol todissolve it. The hydrochloride salt is used most commonly inmedicine, though the free base is absorbed from the GI tractabout equally well. One gram of the hydrochloride salt dissolvesin about 10 mL of water and in 100 mL of alcohol.Tetracycline has become the most popular antibiotic of itsgroup, largely because its plasma concentration appears to behigher and more enduring than that of either oxytetracyclineor chlortetracycline. Also, it is found in higher concentrationin the spinal fluid than the other two compounds.
Pharmaceutical ApplicationsA fermentation product of Streptomyces aureofaciens, also produced from chlortetracycline. Available as the hydrochloride for oral and topical use.
PharmacokineticsOral absorption: c.75%
Cmax 500 mg oral: 2–4 g/L
Plasma half-life: 8.5 h
Volume of distribution: c.1.3 L/kg
Plasma protein binding: c.50–60%
Absorption
When taken with food, absorption is reduced by approximately 50%. Steady-state plasma concentrations of 4–5 mg/L occur after oral doses of 500 mg every 6 h. Women appear to produce higher concentrations than men. Divalent and trivalent cations such as calcium and aluminum present in antacids and milk interfere with absorption through chelation, as does ferrous sulfate. H2-receptor antagonists, by raising gastric pH, also interfere with absorption through impaired drug dissolution. Despite the effect of gastric pH, oral absorption is not affected in elderly patients with achlorhydria.
Distribution
Tetracycline is widely distributed in the body tissues. In particular, it penetrates well into the prostate, uterus, ovary and bladder, and also appears to be preferentially taken up by the gastrointestinal tract. It is also detectable within reticuloendothelial cells of the liver, spleen and bone marrow.
Protein binding is reduced in states of malnutrition. It is also bound to bone, dentine and tooth enamel of unerupted teeth. Sputum concentrations of 0.4–2.6 mg/L have been detected after 250 mg oral dosage every 8 h. Maxillary sinus secretions and bronchial mucosal tissue have concentrations comparable to those of serum.
CSF penetration is poor, but increases with meningeal inflammation. It crosses the placenta readily to enter the fetal circulation, where it achieves 25–75% of the maternal plasma concentration. It is also present in breast milk.
Metabolism
A small amount is metabolized to 4-epitetracycline.
Excretion
Tetracycline is largely eliminated unchanged by glomerular filtration, with more than 50% excreted within 24 h after oral administration. This rises to approximately 70% following parenteral administration. Urinary concentrations of 300 mg/L occur within the first 2 h and persist for up to 12 h. Urinary excretion is enhanced in alkaline urine. Renal clearance is reduced in severe protein calorie malnutrition, possibly through reduced glomerular filtration. It accumulates in the presence of renal failure and is only slowly removed by hemodialysis and minimally by peritoneal dialysis. The bile is an important route of excretion, accounting for about one-third of the dose. Biliary concentrations may be 10–25 times those found in serum. Impaired hepatic function or biliary obstruction leads to an increase in blood levels.
Clinical UseAlong with doxycycline it is one of the most commonly used tetracyclines.
Side effectsThe gastrointestinal side effects common to the group are the most frequent cause of intolerance. Metallic taste and glossitis are less burdensome than diarrhea. Antibiotic-associated enterocolitis caused by Clostridium difficile toxin and staphylococcal enterocolitis have been reported. Steatorrhea and acute pancreatitis has also been described. Irritation and ulceration of the esophagus has occurred with local impaction of the drug. C. albicans overgrowth is common and may result in symptomatic oral or vaginal candidiasis and occasionally candida diarrhea.
Hypersensitivity reactions include contact dermatitis, urticaria, facial edema and asthma. Anaphylaxis is rare. A lupus syndrome has been reported, but its cause is uncertain. Photosensitivity can be severe and cause vesiculation, desquamation and onycholysis. The Jarisch–Herxheimer reaction has been observed in the treatment of syphilis, louse-borne relapsing fever, leptospirosis, brucellosis and tularemia. Deposition in deciduous teeth and bone (where it may temporarily inhibit growth) is of continuing concern. Between 3% and 44% of administered tetracycline is incorporated in the inorganic phase of bone, which may become visibly discolored and fluoresce. Concentrations as high as 290 mg/g have been recorded in bone in those on long-term tetracycline treatment for acne.
Existing renal insufficiency may be aggravated and is probably related to the antianabolic effect of this class of drugs; interference with protein synthesis places an additional burden on the kidney from amino acid metabolism. Acute renal failure may occur and can be aggravated by drug-induced diarrhea. Dehydration and salt loss from diuretic therapy may aggravate nephrotoxicity. Methoxyflurane and tetracycline in combination may be synergistically nephrotoxic.
An uncommon but serious adverse reaction is acute fatty liver, which may be complicated by renal insufficiency and electrolyte abnormalities. This is most likely to occur with highdose intravenous administration, especially during pregnancy. Hematological toxicity is uncommon. Leukopenia, thrombocytopenia and hemolytic anemia have been reported.
Altered coagulation may also occur with high intravenous dosage. Phagocyte function may be impaired as a result of the increased excretion of vitamin C.
Neurological toxicity is uncommon but includes benign intracranial hypertension . A transient myopathy has complicated long-term oral use for the treatment of acne, while intravenous administration has caused increased muscle weakness in those with myasthenia gravis and has also potentiated curare-induced neuromuscular blockade.
Metabolic effects include: precipitation of lactic acidosis in diabetic patients receiving phenformin; a reduction in vitamins B12, B6 and pantothenic acid with long-term therapy; interference with laboratory tests of urinary catecholamines and urinary tests for glucose (Clinitest and Benedict’s); and elevation of serum lithium concentrations. In addition, warfarin is potentiated and failure of oral Contraception occurs.
Potential ExposureTetracycline is an antibiotic medicine used as capsules, tablets, or intravenous injections against certain infections in humans and animals.
Veterinary Drugs and TreatmentsThe tetracyclines are most useful in cats for the treatment of Chlamydial and Mycoplasma conjunctivitis as well as nonspecific or symptomatic therapy for undiagnosed (causative organism not determined) conjunctivitis in cats. While its use in dogs and horses is questionable, it may be useful in goats for Chlamydial/ Mycoplasma keratoconjunctivitis. At the time of publication, there are no commercially available ophthalmic dosage forms of tetracycline. There are, however, Veterinary-Labeled forms of oxytetracycline and Polymyxin B ophthalmic ointments (Terramycin?). It is again, important to note, that severe anaphylaxis, sometimes fatal, has been associated with topical Polymyxin and neomycin in cats and caution is recommended when using this product in cats.
