<p>Pefloxacin mesylate is a prodrug of pefloxacin that is hydrolyzed to the active form in vivo. Pefloxacin is an antibiotic that inhibits bacterial growth by interfering with DNA synthesis by binding to the bacterial ribosome, thereby blocking protein synthesis. This drug has been shown to be effective against gram-positive bacteria such as Streptococcus pneumoniae and Staphylococcus aureus. However, it is not active against gram-negative bacteria such as Escherichia coli or Pseudomonas aeruginosa. Pefloxacin mesylate dihydrate can be administered intravenously at a low dose without any adverse effects on healthy adults. It has also been shown to inhibit the growth of antibiotic-resistant strains of many species, including methicillin-resistant Staphylococcus aureus (MRSA) and Enterococcus faecium.</p>

<p>Erythromycinacistrate is a macrolide antibiotic, which is derived from the bacterium *Saccharopolyspora erythraea*. Its mode of action involves binding to the 50S ribosomal subunit of susceptible bacteria, thereby inhibiting protein synthesis. This action effectively halts bacterial growth and replication, making it particularly effective against a wide range of Gram-positive and some Gram-negative bacteria.</p>
