Product Name:Azithromycin dihydrate

CAS:117772-70-0

MF:C38H74N2O13

Melting point :126 ℃
form:powder
color:White or almost white
Uses:

Azithromycin Dihydrate is the most common crystalline (salt/hydrate) form of azithromycin, a macrolide antibiotic. It is mainly used to treat respiratory tract, skin and other infections caused by susceptible bacteria and atypical pathogens such as Mycoplasma and Chlamydia. Its key advantages are low dosing frequency and strong tissue penetration.

Main Uses (Indications)

According to drug labeling/regulatory information, azithromycin is mainly used for infections caused by susceptible organisms, including:

Respiratory tract infections: pharyngitis, tonsillitis, sinusitis, otitis media, bronchitis and various types of pneumonia.

Other infections: urethritis and cervicitis caused by Chlamydia trachomatis and similar organisms, as well as some skin and soft-tissue infections.

Key Selling Points / Advantages

Broad antibacterial spectrum — effective against many Gram-positive bacteria, some Gram-negative bacteria, and atypical pathogens such as Mycoplasma and Chlamydia.

Strong tissue penetration — after absorption, the drug distributes rapidly and widely into tissues; concentrations in infected tissues are far higher than in non-infected tissues, and it achieves high intracellular concentrations, giving strong antibacterial activity.

Long half-life, short course of treatment — the elimination half-life is approximately 68 hours, so therapeutic levels are maintained in the body for a long time. This allows a simplified regimen of once daily for only 3–5 days, unlike traditional antibiotics that must be taken three or four times a day.

Precautions

Azithromycin is a prescription medicine and should be purchased and used only with a doctor's prescription after a clear diagnosis. Common adverse reactions during treatment include gastrointestinal discomfort such as diarrhoea, nausea and abdominal pain, as well as skin reactions such as rash. It must not be used by patients with a history of hypersensitivity to erythromycin or other macrolides, or those with severe hepatic impairment.
