Tetracyclines are a group of broad-spectrum antibiotic compounds that have a common basic structure and are either isolated directly from several species of Streptomyces bacteria or produced semi-synthetically from those isolated compounds. Tetracyclines are named for their four ("tetra-") hydrocarbon rings ("-cycl-") derivation ("-ine"). They are defined as a subclass of polyketides, having an octahydrotetracene-2-carboxamide skeleton and are known as derivatives of polycyclic naphthacene carboxamide. While all tetracyclines have a common structure, they differ from each other by the presence of chloride, methyl, and hydroxyl groups. These modifications do not change their broad antibacterial activity, but do affect pharmacological properties such as half-life and binding to proteins in serum. Tetracyclines were discovered in the 1940s and exhibited activity against a wide range of microorganisms including gram-positive and gram-negative bacteria, chlamydiae, mycoplasmas, rickettsiae, and protozoan parasites. Tetracyclines are among the cheapest classes of antibiotics available and have been used extensively in the prophylaxis and therapy of human and animal infections, as well as at subtherapeutic levels in animals feed as growth promoters.

Try it risk-free There's a good chance that you can thank antibiotics for being alive. Antibiotics are drugs that target bacteria and either kill them outright or prohibit them from multiplying. If you've ever had a bacterial infection, you've probably relied on them to feel better, or even survive. There are many different antibiotics, and two very well-known ones are called doxycycline and amoxicillin. In this lesson, we'll go over some brief but important points about each medication and then help you compare the two.

They are two very similar drugs, but they do have their differences. They are even used to treat many of the same things. They are antibiotics called doxycycline and tetracycline. Let's go over some of their similarities and differences in this lesson. Doxycycline is a drug that's found in numerous brand name medications, including Vibramycin and Adoxa. Similarly, tetracycline is a generic drug that can be found in the following brand name medications: Brodspec and Tetracap. Both of these drugs target bacteria in a similar fashion.
Applies to doxycycline: oral capsule, oral capsule extended release, oral powder for suspension, oral syrup, oral tablet, oral tablet delayed release Along with its needed effects, doxycycline may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention. Some side effects of doxycycline may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them: Applies to doxycycline: injectable powder for injection, oral capsule, oral delayed release capsule, oral delayed release tablet, oral kit, oral powder for reconstitution, oral syrup, oral tablet, oral and topical kit Very common (10% or more): Headache (up to 26%) Common (1% to 10%): Sinus headache Rare (0.01% to 0.1%): Bulging fontanels (in infants), benign intracranial hypertension (pseudotumor cerebri [symptoms include blurred vision, scotomata, diplopia]), tinnitus Frequency not reported: Hypoesthesia, increased intracranial pressure, paresthesia, somnolence, stupor, taste loss, drowsiness, amnesia, paresthesias of body areas exposed to sunlight, phrenic nerve paralysis after sclerotherapy Postmarketing reports: Pseudotumor cerebri, headache, dizziness Benign intracranial hypertension resulting in permanent loss of vision has been reported. A 70-year-old female patient with no significant medical history suddenly developed a severe headache followed by vomiting about 15 minutes after the initial dose of this drug.

Try it risk-free Did you know that when you are prescribed a drug there may be more than one version of it? And, yes, that could mean a different brand name or a different dosage form, like a capsule versus a tablet. But it could also mean it's almost the same drug, simply a different salt of the drug. Find out as we discuss doxycycline hyclate versus doxycycline monohydrate in this lesson. First, let's quickly go over what doxycycline actually is. Doxycycline is a kind of antibiotic, a drug that targets bacteria, of the tetracycline class of antibiotics.
