Description:

WARNING: This product is for research use only, not for human or veterinary use.

Amoxicillin, also spelled amoxycillin and amox, is an antibiotic useful for the treatment of a number of bacterial infections. Amoxicillin is a broad-spectrum semisynthetic antibiotic similar to Ampicillin except that its resistance to gastric acid permits higher serum levels with oral administration. It is the first line treatment for middle ear infections. It may also be used for strep throat, pneumonia, skin infections, and urinary tract infections among others. It is taken orally. This drug acts by inhibiting the synthesis of bacterial cell walls. It inhibits cross-linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram-positive and Gram-negative bacteria. It has two ionizable groups in the physiological range (the amino group in alpha-position to the amide carbonyl group and the carboxyl group).
