Keflex

Keflex (also known as Cephalexin) is a type of antibiotic that belongs to the class of cephalosporin antibiotics. It is used to treat a variety of bacterial infections, including those of the skin, bone, and respiratory tract.

Medical Uses

Keflex is primarily used to treat bacterial infections. It is effective against a wide range of bacteria, including Staphylococcus aureus, Streptococcus pneumoniae, and Escherichia coli. It is often used to treat skin and soft tissue infections, bone infections, and respiratory tract infections.

Side Effects

Like all antibiotics, Keflex can cause side effects. The most common side effects include nausea, vomiting, diarrhea, and abdominal pain. In rare cases, Keflex can cause serious side effects, such as allergic reactions, kidney damage, and Clostridium difficile infection.

Mechanism of Action

Keflex works by interfering with the formation of the bacteria's cell wall. This causes the cell wall to weaken and eventually rupture, leading to the death of the bacteria.

Pharmacokinetics

After oral administration, Keflex is well absorbed from the gastrointestinal tract. It is not significantly metabolized in the body and is excreted unchanged in the urine.

History

Keflex was first approved for medical use in the United States in 1971. It is now available as a generic medication.
