Description
Azithromycin Product Overview
Azithromycin is a semi-synthetic, 15-membered macrolide (an azalide) derived from Erythromycin. It is a white or almost white crystalline powder that is practically insoluble in water and freely soluble in ethanol and methylene chloride. Its strength is expressed as potency, typically 945–1030 µg/mg.
Pharmaceutical companies use it in film-coated tablets, capsules, powders for oral suspension and intravenous infusions. Its long half-life allows short treatment courses, which made it one of the most widely used antibiotics. The dihydrate form, listed separately as Azithromycin 2-hydrate, is the most common form in oral products.
Related antibiotics in our range include Clarithromycin and the lincosamide Clindamycin Hydrochloride. Zyntex supplies it from qualified API producers, only to companies licensed for pharmaceutical use.
