    Azithromycin metabolism


    This chapter reviews the current pharmacokinetic information available on the new macrolides, including the pharmacokinetics, metabolism, and drug-drug interaction potency of 14 and 15-membered ring macrolides. It also discusses ketolides which are currently under development and are regarded as the third generation of semisynthetic macrolides. The pharmacokinetics of macrolides is generally complicated. Factors such as the half-life of the compound in blood and deep compartments, its tissue affinity including its relative serum or tissue concentrations, and its intracellular penetration, all are considered when choosing a macrolide. On the basis of pharmacokinetic profiles, new macrolides offer significant improvements over erythromycin and a choice between roxithromycin, which offers much improved serum concentrations, an improved half-life, and greater cellular penetration; azithromycin, which has lower serum levels but a very prolonged half-life, low protein binding and high tissue and cellular concentrations, and finally clarithromycin, which offers a combination of the beneficial attributes of the first two agents. New macrolides, especially clarithromycin, should be used cautiously in patients receiving concomitant medications that are metabolized by the cytochrome P-450 system and are known to interact with erythromycin. buy viagra online Zithromax Oral Suspension: 100 mg/5m L Oral suspension: 200 mg/5m L 500 mg powder for injection Tablets: 250 mg & 600 mg Azithromycin, an azolide, is a subclass of the macrolide antibiotics. It is derived from erythromycin, but its chemical structure differs slightly by having a methyl-substituted nitrogen atom in the lactone ring. Azithromycin has the ability to block protein synthesis. This drug is primarily bacteriostatic, but can be bactericidal depending on the concentration given. It is effective against aerobic Gram-positive microorganisms (e.g., Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pneumoniae, Streptococcus pyogenes), and some Gram-negative organisms (e.g., Haemophilus spp, Moraxella catarrhalis). However, azithromycin does not appear to have any inherent direct activity against Pseudomonas aeruginosa (a Gram-negative, rod-shaped, opportunistic pathogen). Other susceptible organisms are Chlamydophila pneumoniae, Chlamydia trachomatis, and Mycoplasma.

Azithromycin is a macrolide antibiotic used for the treatment of a number of bacterial infections. This includes middle ear infections, strep throat, pneumonia, traveler's diarrhea, and certain other intestinal infections. 2

    Azithromycin has relatively broad but shallow antibacterial activity. It inhibits some Gram-positive bacteria, some Gram-negative bacteria, and many atypical bacteria. A strain of gonorrhea reported to be highly resistant to azithromycin was found in the population in 2015. Neisseria gonorrhoeae is normally susceptible to azithromycin, Safety of the medication during breastfeeding is unclear. It has been reported that because only low levels are found in breastmilk and the medication has also been used in young children, it is unlikely that breastfed infants would suffer adverse effects. Most common adverse effects are diarrhea (5%), nausea (3%), abdominal pain (3%), and vomiting. Fewer than 1% of people stop taking the drug due to side effects.

As a Macrolide antibiotic Zithromax inhibits bacterial protein synthesis and prevents bacteria from growth and propagation. It is used to treat infections of upper and low respiratory organs (tonsillitis, otitis, sinusitis, pneumonia), urogenital infections (urethritis, prostatitis, cervicitis, adnexitis caused by chlamydia, gonorrhea, early syphilis), intestinal infections, ulcer of stomach and duodenum. Dosage and directions Take exactly as prescribed and do not discontinue your treatment even if you feel fine and your symptoms improved without permission of your doctor. To prepare a liquid suspension form one dose packet mix one packet with 2 ounces of water, shake and drink at once. Do not use the suspension which was prepared longer than 12 hours ago. Tablets and suspension can be taken with or without food while capsules should be taken on an empty stomach 2 hours before or after a meal.

    Some side effects 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: Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

    At any given time, more than 10 million women in the United States are pregnant or lactating, and exposing a fetus or newborn to antibiotics can pose a unique threat. Changes during pregnancy and lactation also can trigger pharmacokinetic and pharmacodynamic modifications that alter the effectiveness of antibiotics. Nahum and colleagues reviewed the literature on antibiotic use to provide updated, evidence-based information on antibiotic use in women who are pregnant or lactating. The researchers examined published medical literature, sources on teratogenicity and prescribing for women who are lactating or pregnant, and they abstracted data from product labels for drugs approved by the U. Food and Drug Administration (FDA) for use during pregnancy. The authors identified 124 references that covered 11 commonly prescribed antibiotics, all of which cross the placenta and are excreted in human breast milk. There was no teratogenic potential for penicillins G and V potassium (V-Cillink); unlikely potential for amoxicillin, chloramphenicol (Chloromycetin), ciprofloxacin (Cipro), doxycycline (Vibramycin), levofloxacin (Levaquin), and rifampin (Rifadin); and undetermined potential for clindamycin (Cleocin), vancomycin, and gentamicin. All agents were FDA Pregnancy Category B (amoxicillin, clindamycin, penicillin G, penicillin V potassium, and vancomycin) or C (chloramphenicol, ciprofloxacin, gentamicin, levofloxacin, and rifampin), except for doxycycline, which was category D.
