Description
Description
Erythromycin primarily exerts its antibacterial effect by binding to the 50S subunit of bacterial ribosomes, inhibiting protein synthesis. It interferes with the translocation process, preventing the ribosome from moving along the messenger RNA, thereby disrupting the assembly of bacterial proteins. Erythromycin is particularly effective against gram-positive bacteria and some gram-negative organisms. Isotretinoin gel, on the other hand, acts by normalizing epithelial differentiation and reducing sebaceous gland activity. It binds to specific nuclear receptors, regulating gene expression and influencing cellular processes such as cellular differentiation, keratinization, and sebum production. This mechanism helps to reduce the formation of acne lesions by preventing the development of comedones and inhibiting the growth of Propionibacterium acnes, a bacterium associated with acne.
