Antibiotiques

Tobramycin used to treat severe infections with gram-negative bacteria and it is often applied in combination with beta-lactams. It has similar antimicrobial effects to gentamicin and is effective against all Enterobacteriacae, but more effective than gentamicin against P. aeruginosa, which is why it is often used for gentamicin-resistant strains, especially in the case of cystic fibrosis.

Inhibitor of protein synthesis; aminoglycoside

Dihydrostreptomycin sesquisulfate, EP is an aminoglycoside antibiotic, structurally derived from Streptomyces griseus. This compound originates from microbial biosynthesis, a method which harnesses the natural antibiotic-producing capabilities of microbial cultures. The mode of action of dihydrostreptomycin sesquisulfate involves binding to the 30S subunit of bacterial ribosomes, which interrupts the process of protein synthesis, ultimately leading to bacterial cell death.

Inhibitor of protein synthesis; aminoglycoside

Sulfasalazine is a disease-modifying anti-rheumatic drug (DMARD) with action on reducing inflammation and immune system activity and is used for treating rheumatoid arthritis and inflammatory bowel disease.

Teicoplanin is related to vancomycin and has similar effects against gram-positive bacteria and anaerobes, and usually requires less frequent administration than vancomycin, but it is less efficient against S. haemolyticus. Due its size and polarity, teicoplanin can’t pass through the membrane of gram-negative bacteria thus it is not active against them. It is used to treat severe infections such as septicemia, endocarditis, bone and joint infections.

Inhibitor of RNA synthesis
