Basics

Lymecycline is a second-generation, broad-spectrum tetracycline antibiotic used to treat acne and other susceptible bacterial infections. Some of these infections include upper respiratory tract infections, urinary tract infections, bronchitis, chlamydial infections, and rickettsial infections.

Pharmacology

Pharmacodynamics

Lymecycline binds to the so-called 30S ribosomal subunit and thus prevents aminoacyl-tRNA from binding to the ribosome, which prevents the elongation of polypeptide chains (proteins). This leads to a bacteriostatic effect and thus inhibits the multiplication of pathogens.

Pharmacokinetics

Lymecycline is 77-88% absorbed after oral administration with a relative bioavailability of 70%. Lymecycline is excreted 25% in the urine. The half-life of lymecycline is approximately 8 hours.
