Erythromycin is a broad-spectrum, macrolide antibiotic with antibacterial activity. Erythromycin diffuses through the bacterial cell membrane and reversibly binds to the 50S subunit of the bacterial ribosome. This prevents bacterial protein synthesis.

What is the mode of action of erythromycin?

Erythromycin acts by inhibition of protein synthesis by binding to the 23S ribosomal RNA molecule in the 50S subunit of ribosomes in susceptible bacterial organisms.

What is an antibiotic spectrum of activity?

The antimicrobial spectrum of an antibiotic means the range of microorganisms it can kill or inhibit. Antibiotics can be divided into broad-spectrum antibiotics, extended-spectrum antibiotics and narrow-spectrum antibiotics based on their spectrum of activity.

What is broad-spectrum antibiotics?

Examples of broad-spectrum antibiotics

  • Aminoglycosides (except for streptomycin)
  • Ampicillin.
  • Amoxicillin.
  • Amoxicillin/clavulanic acid (Augmentin)
  • Carbapenems (e.g. imipenem)
  • Piperacillin/tazobactam.
  • Quinolones (e.g. ciprofloxacin)
  • Tetracyclines.

Is erythromycin an agonist?

Erythromycin is a motilin receptor agonist (a G-protein-coupled receptor that stimulates contractions of smooth muscle in the gut) and has been used in the treatment of diabetic gastroparesis.

What is structure of erythromycin?

C37H67NO13Erythromycin / Formula

What type of inhibitor is erythromycin?

Erythromycin is an inhibitor of the cytochrome P450 system, which means it can have a rapid effect on levels of other drugs metabolised by this system, e.g., warfarin.

Which antibiotic has the broadest spectrum of antibiotic activity?

An example of a commonly used broad-spectrum antibiotic is ampicillin….Examples of broad-spectrum antibiotics

  • Azithromycin.
  • Carbapenems (e.g. imipenem)
  • Piperacillin/tazobactam.
  • Quinolones (e.g. ciprofloxacin)
  • Tetracycline-class drugs (except sarecycline)
  • Chloramphenicol.
  • Ticarcillin.
  • Trimethoprim/sulfamethoxazole (Bactrim)

What is broad-spectrum activity?

Broad-spectrum antibiotic activity and notable broad-spectrum antibiotics. Broad-spectrum antibiotics are antibiotics that are active against many Gram-positive and Gram-negative bacteria. In contrast, narrow-spectrum antibiotics are only effective against Gram-positive or Gram-negative bacteria.

Which antibiotics are narrow-spectrum?

Examples of narrow-spectrum antibiotics are the older penicillins (penG), the macrolides and vancomycin. Examples of broad-spectrum antibiotics are the aminoglycosides, the 2nd and 3rd generation cephalosporins, the quinolones and some synthetic penicillins.

Which antibiotic has the broadest spectrum of activity?

Is moxalactam Gram positive or negative?

Moxalactam is resistant to the action of beta-lactamase, penicillinase, and cephalosporinase, which are produced by Gram-negative and Gram-positive bacteria. Many strains of a number of microorganisms that possess multiple resistance to other antibiotics— semisynthetic penicillins, cephalosporins, and aminoglycosides—are sensitive to moxalactam.

When was moxalactam first used in the US?

It was approved for marketing in the United States in 1982 and is sold commercially by the Eli Lilly Co. The greatly improved spectrum and potency of moxalactam toward Gram-negative bacteria has been attributed to its improved stability toward the β-lactamases, bacterial enzymes which can degrade the β-lactam antibiotics.

What is the physiologic effect of erythromycin?

Erythromycin is a Macrolide and Macrolide Antimicrobial. The physiologic effect of erythromycin is by means of Decreased Sebaceous Gland Activity.

Is erythromycin a macrolide or antimicrobial?

Erythromycin is a Macrolide and Macrolide Antimicrobial. The physiologic effect of erythromycin is by means of Decreased Sebaceous Gland Activity. The chemical classification of erythromycin is Macrolides. Erythromycin is a broad-spectrum, macrolide antibiotic with antibacterial activity.
