A pharmaceutical company, affiliated to the Social Security Organization, has used the latest technology in production of beta-lactam antibiotics. The locally produced antibiotics are now available in the market at half the price of the imported medicines and will help save $5 million, said Dr. Naderi Alizadeh, head of the Iranian Antibiotics Production Company, reports IRNA. The beta-lactam ring is part of the structure of several antibiotic families, the principal ones being the penicillins, cephalosporins, carbapenems, and monobactams, which are, therefore, also called beta-lactam antibiotics.
