Mechanism of Action

The nature of bacteria is to replicate, and to do so, they undergo a specific process with the help of protein synthesis. These are ribosomal proteins.

Azithromycin initiates the ceasing activity by binding with the 23S rRNA of the 50S ribosomal subunit of the bacteria. To precisely stop the bacterial infection, it stops the protein synthesis process by inhibiting the assemblage of the 50S ribosomal subunit. Azithromycin is a macrolide that has a strong affinity for bacterial ribosomes.

This drug is highly stable in low pH that cast a long half-life to the serum by increasing the concentration in the tissues. (3)

Bio Absorption

37% of azithromycin is orally absorbed. It is generally absorbed in the intestine by the P-glycoprotein efflux transporter encoded by ABCB1 gene. Its half-life is 68 hours. It is not applicable for antibiotic resistant bacteria treatment. (4)


The Azithromycin dose varies from 500mg to 2g based on the severity of bacterial intrusion. One may take it for a maximum of 5 days. In the case of urinary infection, one single dose of 2g can be taken.

Two modes of administration are tablets and suspension. While taking the liquid suspension, one must use a measuring cup, dosing spoon, or oral syringe. As the right dosage is very important to cure the ailment. (5)
