    Azithromycin mode of action


    Azithromycin is a macrolide antibiotic which inhibits bacterial protein synthesis, quorum-sensing and reduces the formation of biofilm. Accumulating effectively in cells, particularly phagocytes, it is delivered in high concentrations to sites of infection, as reflected in rapid plasma clearance and extensive tissue distribution. Azithromycin is indicated for respiratory, urogenital, dermal and other bacterial infections, and exerts immunomodulatory effects in chronic inflammatory disorders, including diffuse panbronchiolitis, post-transplant bronchiolitis and rosacea. Modulation of host responses facilitates its long-term therapeutic benefit in cystic fibrosis, non-cystic fibrosis bronchiectasis, exacerbations of chronic obstructive pulmonary disease (COPD) and non-eosinophilic asthma. Initial, stimulatory effects of azithromycin on immune and epithelial cells, involving interactions with phospholipids and Erk1/2, are followed by later modulation of transcription factors AP-1, NFκB, inflammatory cytokine and mucin release. Delayed inhibitory effects on cell function and high lysosomal accumulation accompany disruption of protein and intracellular lipid transport, regulation of surface receptor expression, of macrophage phenotype and autophagy. These later changes underlie many immunomodulatory effects of azithromycin, contributing to resolution of acute infections and reduction of exacerbations in chronic airway diseases.

Macrolides exert their antibiotic effect by binding irreversibly to the 50S subunit of bacterial ribosomes. Ribosomes are the protein factories of the cell, and by binding to the ribosome, macrolides inhibit translocation of ttranslation (the production of proteins under the direction of DNA). Although the cells of humans also have ribosomes, these eukaryotic cellular protein factories differ in size and structure from the ribosomes of prokaryotes. This action is mainly bacteriostatic, meaning that bacterial growth and reproduction are inhibited, in contrast to bactericidal antibiotics which directly kill bacteria. Macrolides can be bactericidal in high concentrations.

    CLINICAL PHARMACOLOGY. Mechanism Of Action. Azithromycin is a macrolide antibacterial drug. see Microbiology. Azithromycin concentrates in phagocytes. Azithromycin ist eine organische chemische Verbindung aus der Gruppe der Glycoside, der als antibiotisch wirkender Arzneistoff der Gruppe der. Azithromycin is a broad-spectrum macrolide antibiotic with a long half-life and a high degree of tissue penetration. It was initially approved by the FDA in 1991.

    Its molecular formula is C38H72N2O12, and its molecular weight is 749.00. Azithromycin has the following structural formula: Azithromycin is a bacteriostatic drug acts by inhibiting protein synthesis. It binds reversibly to 50S ribosomal subunits of sensitive microorganism. Azithromycin interferes with transpeptidation and translocation thus there is inhibition of protein synthesis and hence inhibition of cell growth. Azithromycin is rapidly absorbed after oral administration. burgdorferi, Mycoplasma pneumoniae, Escherichia coli, Salmonella, Shigella species and H. Azithromycin is contraindicated in patients with known hypersensitivity to azithromycin, erythromycin, any macrolide or ketolide antibiotic. Food does not interfere with absorption of tablet or suspension of azithromycin but of capsule is reduced. It may cause QTc Prolongation, so avoid in patients with known QT prolongation. Peak plasma concentrations occur 2 to 3 hours after an oral dose and 1 to 2 hours after intravenous dosage. avium-intracellulare, Toxoplasma gondii, Cryptosporidium, Plasmodium species, H. Side effects with azithromycin are less frequent ( Azithromycin is an erythromycin derivative and its lactone ring contains an extra nitogen which is methylated. These structural alterations improve acid stability and tissue penetration and widen the spectrum of activity. 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.

    A popular diabetes medication appears to have significant benefits beyond simply treating the disease. Patients taking metformin — which is sold under brand names Glucophage and Fortamet — have a lower risk of heart attacks, strokes and even death than those on sulfonylureas, an extensive study has found. Researchers analyzed data from hundreds of thousands of veterans with type 2 diabetes to compare the two types of widely prescribed drugs. Metformin users “faced a ‘modest but clinically important’ 21 percent lower risk of hospitalization because of cardiovascular complications than users of sulfonylureas (glyburide and glipizide),” according to . Although they concluded that metformin should be the preferred treatment for type 2 diabetes, the researchers couldn’t determine if metformin protects against heart trouble or if sulfonylureas increase heart disease. Furthermore, 97 percent of the study participants were male and 75 percent were white, so it’s unclear if the findings would apply to women or other racial groups. Christianne Roumie of the Geriatric Research Education Clinical Center at the Nashville Veterans Affairs Medical Center in Tennessee, and her team tracked 250,000 veterans ages 18 and older who started one of the drugs between 20. Steven Nissen, chairman of the department of cardiovascular medicine at the Cleveland Clinic in Ohio, explains the significance of the study, saying that at least two-thirds of diabetes patients will die of heart disease. “While the signals pointing to this situation have probably been there for several decades the [U. Food and Drug Administration] did not require testing for cardiovascular outcomes when looking at diabetes drugs until very recently,” he said.

    It comes as a tablet or suspension you take by mouth. Fluconazole oral tablet is available as both a generic drug, and as the brand-name drug Diflucan. Generic drugs usually cost less than the brand-name version. In some cases, they may not be available in all strengths or forms as the brand-name drug. Fluconazole is used to prevent and treat candidiasis. This condition is caused by infection with one of the many types of the fungus Examples of candidiasis include vaginal yeast infection, as well as oral yeast infection (thrush).
