Why is Erythromycin so expensive?

Your local pharmacies tend to offer brand-name versions of this antibiotic that are very expensive. The reason for high cost is obvious. Manufacturers of these brands have spent millions of advertising dollars to make sure you know their brand. Having invested millions of dollars in advertising, their brand is now expensive. However, after the patent protection period, the original molecule, which became the basis for the new drug, can be reproduced in the form of a generic drug (a drug with the same basic composition and properties) by other manufacturers. Accordingly, generic manufacturers can reduce the cost of the final product. There are a number of companies that specialize in generics (including our pharmacy). The “generic” is not a synonym for poor quality or low cost. The reproducible molecule must meet the characteristics of the original drug, and its production also requires significant investment. In addition, a number of generic manufacturers can afford to keep the price low due to significant volumes of production, and, accordingly, sales.
