Ampicillin-sulbactam only comes in a parenteral formulation to be either used as intravenous or intramuscular injections, and can be formulated for intravenous infusion. [2] [17] It is formulated in a 2:1 ratio of ampicillin:sulbactam. The commercial preparations available include: [17] 1.5 grams (1 gram ampicillin and 0.5 gram sulbactam)
Sultamicillin, sold under the brand name Unasyn among others, is an oral form of the penicillin antibiotic combination ampicillin/sulbactam.It is used for the treatment of bacterial infections of the upper and lower respiratory tract, the kidneys and urinary tract, skin and soft tissues, among other organs.
ATC code J01 Antibacterials for systemic use is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
Sulbactam is a β-lactamase inhibitor. This drug is given in combination with β-lactam antibiotics to inhibit β-lactamase, an enzyme produced by bacteria that destroys the antibiotics. [1] It was patented in 1977 and approved for medical use in 1986. [2]
The efficacy of sulbactam/durlobactam was established in a multicenter, active-controlled, open-label (investigator-unblinded, assessor-blinded), non-inferiority clinical trial in 177 hospitalized adults with pneumonia caused by carbapenem-resistant A. baumannii. [2]
Another common indication for colonoscopy is the investigation of iron deficiency with or without anaemia. The examination of the colon, to rule out a lesion contributing to blood loss, along with an upper gastrointestinal endoscopy (gastroscopy) to rule out oesophageal, stomach, and proximal duodenal sources of blood loss.
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates (tazobactam and sulbactam) which ultimately leads to the degradation of the beta-lactamase. [7] Avibactam on the other hand does not contain a beta-lactam ring (non beta-lactam beta-lactamase inhibitor), and instead binds reversibly .
