Tetracycline Hydrochloride is a anti-biotic which controls AMINO ACYL TRNA binding at the time of protein synthesis. In bacteria, it blocks binding of aminoacyl-TRNA to the mRNA-ribosome complex, thus controls protein synthesis and growth of bacterial cell. Tetracycline Hydrochloride is mainly an oral antibiotic utilized to treat mild-to-moderate infections owing to microbial organisms. As it is an antibiotic, it should be taken under the guidance of your physician because its heavy dosage may result in liver failure and death.
