Cefazolina Introduction

Cefazolina, also known as cephazolin or Kefzol®, is an antibiotic in the medication class known as cephalosporins. Cefazolina is used to treat certain bacterial infections, including those of the skin, respiratory tract, bone, urinary tract, and some soft tissue infections. It can also be used to prevent certain infections prior to surgery. Cefazolina is administered by intravenous (IV) or intramuscular (IM) injection, as well as orally.

Uses For

Cefazolina is used to treat infections caused by certain bacteria. These include infections of the skin, respiratory tract, bones, urinary tract, and some soft tissue infections. Cefazolina can also be used in some pre-operative procedures to prevent certain infections prior to surgery.

Mechanism of Action

Cefazolina works by inhibiting bacterial cell wall synthesis, therefore preventing the growth and division of bacterial cells. Cefazolina binds to penicillin-binding proteins, and this binding prevents bacteria from properly forming their cell walls. This renders the bacteria unable to grow and divide effectively, leading to their eventual death.

How long does it take to work?

Cefazolina typically begins to work within a few hours of being administered. However, the length of time it takes for the infection to be completely cured may depend on the type of infection. Some infections may require multiple doses to be completely cured.

Absorption

Cefazolina is only slightly absorbed when taken by mouth. Most of the medication is destroyed by the digestive system and therefore must be administered by an intravenous or intramuscular injection. Intramuscular doses have a higher bioavailability than intravenous doses.

Route of Elimination

Cefazolina is eliminated from the body primarily through the kidneys. Approximately 70-80% of a given dose is eliminated by the kidneys, while a smaller amount is eliminated via the feces.

Dosage

The dosing for Cefazolina typically depend on the type of infection, the severity of the infection, the patient’s age and size, and any other existing medical conditions that may affect the patient’s response to the drug. Generally, in adults, the recommended dose of Cefazolina is 500 mg intravenously or intramuscularly every 8 hours. In pediatrics, the dosage is 20-50 mg/kg/day divided into two or three doses.

Administration
