A macrolide antibiotic that was originally discovered in 1952, with bacteriostatic action is Erythromycin. It works by stopping the further growth of bacteria rather than directly destroying it. This is achieved by inhibiting protein synthesis.

Erythromycin is used for treating various infections and also indicates a non-infectious pathology. It is active against both gram-positive bacteria, gram-negative bacteria, and several other organisms.

Erythromycin is available in oral form, intravenous form, topical form for the skin, and as an ophthalmic preparation for the eyes.



CAS No - 114-07-8

But, Erythromycin’s instability under the acidic conditions that are present in the stomach can give inactive by-products resulting in low bioavailability. These by-products are present in the form of metabolites. Others are generated during the time of drug development and manufacturing process.

As per the ICH guidelines, the presence of these byproducts must lie within the criteria of the desired guidelines so that the drug product is fit for human consumption.

Henceforth, these byproducts need to be identified, isolated, quantified and characterized in the drug material and drug product.
