Doxycycline HCL

Doxycycline hydrochloride is the hydrochloride form of doxycycline, being a tetracycline antibiotic that has enjoyed widespread use in both veterinary and human medicine owing to its relatively broad spectrum and wide margin of safety. The first members of the tetracycline class were isolated from several species of bacteria from the genus Streptomyces in the1940s and 1950s. Since that time, a variety of tetracycline have been discovered, both naturally produced (e.g., chlortetracycline) and semisynthetic (e.g., doxycycline and tetracycline). Doxycycline was discovered in 1967 and has undergone extensive investigation, both for its antimicrobial properties as well as the effects it has on the physiology of higher organisms[1].
