How This Drug Works
Beta Lactam Antibiotics
Beta-lactam antibiotics include Penicillins, Cephalosporins, and Carbapenams and treat a variety of bacterial infections. They prevent the growth of bacteria by damaging the cell wall, bacteria's strongest protection from the environment.
"Beta&#45;lactam antibiotics treat a variety of bacterial infections. They prevent the growth of bacteria by damaging the cell wall, bacteria&#39;s strongest protection from the environment.<br><br> Bacteria are everywhere. Some can be &#34;good&#34; bacteria but infections can occur when large amounts of any type of bacteria sneak past the body&#39;s natural defenses and multiply. Bacteria multiply by growing and splitting in half. One of the last steps in this process is sealing off the opening in the cell wall.<br><br> Beta&#45Lactam antibiotics have a commonly shaped structural piece, called the &#34;Beta&#45;Lactam ring,&#34; which allows these drugs to bind proteins and, in turn, prevent the formation of a cell wall. Beta&#45;lactam antibiotics attach to and inactivate enzymes in the bacterial cell membrane. This interferes with how bacteria form their cell wall, which stops bacteria from growing and multiplying.
