Examples of macrolides include clarithromycin, erythromycin

They prevent peptidyltransferase from adding the growing peptide attached to tRNA to the next amino acid as well as inhibiting ribosomal translation. 

They do so by binding reversibly to the P site on the subunit 50S of the bacterial ribosome.

Macrolides bind reversibly to the P site on the 50S subunit of bacterial ribosome to inhibit protein synthesis.
