Zithromax

Zithromax

Zithromax is the brand name of azithromycin. Zithromax is used to decrease the multiplication of drug-resistant bacteria and uphold the effectivity of antibacterial action. The medicine must be utilized only for the treatment of bacterial infections or to prevent the infections which are strongly believed to be caused by different types of bacteria.

Zithromax is available in the market in the form of tablets and oral suspension. The drug contains the active component azithromycin, an azalide, which is a subclass of group macrolide antibiotics. The drug is only for oral administration. The antibiotic azithromycin has been derived from another antibiotic called erythromycin; however, azithromycin varies chemically from erythromycin. Zithromax is a capsular-shaped, film-coated tablet consists of azithromycin dihydrate as the main ingredient (either 250 mg or 500 mg) and other inactive ingredients like dibasic calcium phosphate anhydrous, hypromellose, lactose, magnesium stearate, pregelatinized starch, sodium croscarmellose, sodium lauryl sulfate, titanium dioxide, and triacetin. One bottle oral suspension of Zithromax consist of azithromycin dihydrate (300 mg, 600 mg, 900 mg, or 1200 mg) and other inactive components like anhydrous, hydroxypropyl cellulose, sodium phosphate, sucrose, tribasic, xanthan gum, and added flavors.

Azithromycin performs by adhering to the 50S ribosomal subunit of sensitive microorganisms and, therefore, intervening with the synthesis of microbial proteins; however, the synthesis of nucleic acid is not getting affected. Azithromycin has been proved to be effective against most of the following aerobic and facultative Gram-positive bacteria: Staphylococcus aureus, Streptococcus agalactiae, S. pneumoniae, and S. pyogenes. Azithromycin shows cross-resistance with the Gram-positive erythromycin-resistant strains. Most forms of Enterococcus faecalis and methicillin-resistant staphylococcus bacteria are resistant to azithromycin.

The medicine is active against aerobic and facultative Gram-negative microbes like Haemophilus ducreyi, H. influenzae, Moraxella catarrhalis, and Neisseria gonorrhoeae. It is also effective against the other microorganisms like Chlamydia pneumoniae, C. trachomatis, and Mycoplasma pneumoniae. Severe allergic reactions, including anaphylaxis, angioedema, and dermatologic reactions have been noticed rarely in patients taking azithromycin. If such allergic symptoms have been noticed in any cases, it should be immediately reported to a physician.
