buy Cephalexin pills
There are many groups of antibiotics. However, they are all united by a pronounced selective effect on microorganisms and a slight toxic effect on a macroorganism. Antibiotics: classification, rules and features of use.
Cephalexin are substances that can inhibit the growth of microorganisms or destroy them. According to the GOST definition, antibiotics include substances of plant, animal or microbial origin. Currently, this definition is somewhat outdated, since a huge number of synthetic drugs have been created, however, it was natural Cephalexin that served as the prototype for their creation.
Cephalexin are a huge group of bactericidal drugs, each of which is characterized by its own spectrum of action, indications for use and the presence of certain consequences. The history of antimicrobial drugs begins in 1928, when A. Fleming first discovered penicillin. This substance was precisely discovered, and not created, since it has always existed in nature. In living nature, it is produced by microscopic fungi of the genus Penicillium, protecting themselves from other microorganisms. In less than 100 years, more than a hundred different antibacterial drugs have been created. Some of them are already outdated and not used in treatment, and some are only being introduced into clinical practice.
