Ertapenem Injection and Its Indications

Introduction

Ertapenem injection is prescribed for the treatment of specific severe infections, including urinary tract infections, pneumonia, diabetic foot infections, skin infections, pelvic infections, gynecological infections, and abdominal infections caused by bacteria. Additionally, it is utilized to prevent infections post-colorectal surgery. Ertapenam belongs to the carbapenem antibiotics class and functions by eliminating bacteria.

In vitro, Ertapenem has proven to act against a wide range of gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal effect of Ertapenem arises from its ability to inhibit cell wall synthesis, and this inhibition is facilitated by Ertapenem binding to penicillin-binding proteins (PBPs).

What Is the Purpose of Ertapenem Injection?

1. Prophylaxis for Colorectal Surgery:

• Ertapenem, a sterile and synthetic parenteral 1-beta-methyl-carbapenem, shares a structural relationship with beta-lactam antibiotics.

• This agent has demonstrated bactericidal activity against a spectrum of gram-negative and gram-positive aerobic and anaerobic bacteria.

• Its mechanism involves inhibiting cell wall synthesis by binding to penicillin-binding proteins.

• Originally sanctioned for treating diverse moderate-to-severe bacterial infections, Ertapenem received FDA (The Food and Drug Administration) approval, specifically for prophylaxis against surgical site infections following elective colorectal surgery in adults.

• For the purpose of prophylaxis of surgical site infection after elective colorectal surgery, the recommended dosage of Ertapenem is 1 gram, given as a solitary intravenous dose one hour before the surgical incision.

• Prior to administering the dose, a 1-gram vial of Ertapenem should be reconstituted with 10 mL of water for injection, 0.9 % sodium chloride injection, or bacteriostatic water for injection.

• The reconstituted contents should then be combined with 50 mL of 0.9 % sodium chloride, and the infusion must be completed within six hours of reconstitution.

2. Kidney Transplantation:

• Infections pose a significant challenge following kidney transplantation, particularly in the initial post-transplant month, with a majority stemming from bacterial sources, often originating in the urine.

• In recent times, there has been a noticeable rise in infections caused by multidrug-resistant microorganisms, particularly ESBL-producing Enterobacteriaceae.

• These infections not only incur higher costs but are also associated with increased rates of graft loss and mortality.

• While perioperative prophylaxis is standard to prevent surgical site infections, in urological procedures like kidney transplantation, it additionally aids in averting postoperative bacteriuria.

• Considering the documented efficacy and safety of Ertapenem it is used for surgical prophylaxis before a kidney transplantation.

• Ertapenem has proven to be effective and safe for prophylaxis in patients undergoing abdominal surgery, including procedures involving colorectal manipulation.

What Are the Indications for Using Ertapenem Sodium?

Ertapenem sodium is suggested for the treatment of moderate to severe infections caused by strains of microorganisms that are susceptible to this drug. It is also suitable for initial empiric therapy before identifying the causative organisms in the following infections:

1. Complicated intra-abdominal infections.

2. Community-acquired pneumonia.

3. Ertapenem sodium is suggested for the treatment of complicated skin infections, including those in relation to diabetic lower extremity and diabetic foot infections.

4. Complicated urinary tract infections, including pyelonephritis (bacteria infection leading to kidney inflammation).

5. Bacterial septicemia. It is a severe and life-threatening type of infection in which bacteria enter the blood circulation and start spreading.

6. Acute pelvic infections such as septic abortion (miscarriage due to severe uterine infection), postpartum endometritis (infection of the womb lining), and post-surgical gynecologic infections.

7. Ertapenem is also prescribed for the prophylaxis of surgical site infections post elective colorectal surgery.

How Should One Use Ertapenem Injection?

All directions on the prescription label should be followed, and all medication guides or instruction sheets should be read. The medicine should be used exactly as directed. Ertapnem is injected through a vein or a muscle. All instructions for use should be read and followed. If help is needed, the doctor or pharmacist should be asked. An injection should be prepared only when ready to give it. If the medicine has an unusually cloudy appearance, has changed color, or has particles in it, the help of the pharmacist should be sought. Understanding how to properly mix this medicine with a liquid and how to store the mixture is important. Only the diluent or liquid recommended by the doctor or pharmacist should be used.

The mixture should be shaken well just before a dose is measured. Even if symptoms improve quickly, the medicine should be kept in use. Skipping doses could result in the infection becoming resistant to medication. A viral infection will not be treated by the use of Ertapenem. This medicine should not be shared with another person, even if they have the same symptoms. Store the unmixed powder at room temperature, away from moisture and heat. Once mixed for injection into a muscle, Ertapenem should be used within one hour after the mixing process. Ertapenem should be mixed and diluted for IV (intravenous) injection to be stored for up to 6 hours at room temperature or for a whole day in a refrigerator. The mixture should be used within four hours after removing it from the refrigerator. Needles or syringes should not be reused. They should be placed in a puncture-proof "sharps" container and disposed of following state or local laws. It should be kept out of the reach of children and pets.

What Are the Side Effects of Ertapenem Injection?

The following are the possible side effects after the administration of Ertapenem injection:

• Nausea and vomiting.

• Constipation.

• Diarrhea.

• Headache.

• Stomach ache.

• Dizziness.

• Fever.

• Confusion.

• Cough.

• Difficult staying or falling asleep.

• Irritation or redness at the injection site.

• Swelling or redness in the injection site.

• Vaginal irritation or burning or itching.

• Swelling of the feet, hands, ankles, or lower legs.

Certain side effects can be serious and life-threatening, which may need immediate medical intervention. They are:

• Hives.

• Itching.

• Pale skin.

• Rash.

• Severe diarrhea.

• Difficulty breathing or swallowing.

• Seizures.

• Fast or irregular heartbeat.

• Abnormal weakness or tiredness.

• Chest pain.

• Shortness of breath.

Conclusion

Ertapenem injection is a pharmaceutical utilized in the management of diverse bacterial infections. It is classified under carbapenem antibiotics and demonstrates efficient action against a broad spectrum of gram-negative and gram-positive aerobic as well as anaerobic bacteria. The application of Ertapenem injection encompasses both intravenous and intramuscular routes, and adherence to the recommended dosage and administration instructions provided by healthcare professionals is very necessary.
