Question 1

What is Oritavancin?

Accepted Answer

Oritavancin is a medication classified as a lipoglycopeptide antibiotic. It functions by interfering with the way bacteria build their cell walls, which ultimately leads to the destruction of the bacteria or prevents them from multiplying within the body.

This antibacterial agent belongs to a class of drugs that target the structural integrity of bacterial cells. By disrupting these processes, the medication helps to resolve the underlying bacterial presence and stop the spread of the infection.

Question 2

What is Oritavancin used for?

Accepted Answer

Oritavancin is used to treat acute bacterial skin and skin structure infections.

Question 3

How does Oritavancin work?

Accepted Answer

How Oritavancin Fights Infection

Oritavancin belongs to a class of medications known as lipoglycopeptide antibiotics. It is designed to kill specific types of bacteria, particularly Gram-positive bacteria, by attacking them in multiple ways:

Inhibiting Cell Wall Synthesis: Bacteria need a strong outer wall to survive and multiply. Oritavancin prevents bacteria from properly assembling this wall. Without a functional cell wall, the bacteria cannot maintain their shape or protect themselves from the environment.

Disrupting the Cell Membrane: In addition to attacking the cell wall, oritavancin interacts with the bacterial cell membrane. It causes the membrane to become leaky, which disrupts the electrical balance of the cell and leads to rapid cell death.

Because it works through these different mechanisms, oritavancin is effective against certain bacteria that may have developed resistance to other types of antibiotics. It is important to note that this medication only works against bacterial infections and will not treat viral infections like the common cold or flu.

Question 8

What is the dosage of Oritavancin and how do I take it?

Accepted Answer

Administration

Oritavancin is given as a single dose into a vein through an intravenous (IV) line. This treatment is administered by a healthcare professional in a medical setting, such as a hospital or clinic.

The infusion process takes a specific amount of time to complete, which may vary depending on the formulation used. Because it is a single-dose treatment, you will not need to administer the medication yourself at home.

Missed Dose

Since this medication is provided as a one-time treatment by a healthcare provider, missing a dose is unlikely. If you are unable to attend your scheduled appointment for the infusion, contact your doctor or clinic as soon as possible to reschedule your treatment.

Question 9

Is Oritavancin safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

It is currently unknown if oritavancin can cause harm to an unborn baby. There are no adequate studies in pregnant women to determine the risks of birth defects, miscarriage, or other adverse outcomes. In animal studies, the medication did not show evidence of harm to the fetus, but animal results do not always predict human response.

If you are pregnant or planning to become pregnant, discuss the potential risks and benefits of this treatment with your healthcare provider.

Breastfeeding

It is not known whether oritavancin passes into human breast milk or how it might affect a nursing infant. While animal studies have shown that the drug is present in the milk of lactating rats, human data is unavailable. If you are breastfeeding, consult your doctor to determine the best course of action for you and your baby.

Question 10

What forms and strengths does Oritavancin come in?

Accepted Answer

Oritavancin is supplied as a sterile, lyophilized powder in vials. This medication is prepared and administered only as an intravenous infusion into a vein.

Question 11

What is the FDA approval status of Oritavancin?

Accepted Answer

FDA Approval and Indications

Oritavancin is approved by the U.S. Food and Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI). It is indicated for use against specific Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA).

Regulatory Warnings and Contraindications

The FDA-approved labeling for oritavancin includes specific contraindications and safety warnings regarding laboratory testing interference:

Heparin Contraindication: The use of intravenous unfractionated heparin sodium is contraindicated for 120 hours (5 days) after the administration of oritavancin. This is because oritavancin can artificially prolong activated partial thromboplastin time (aPTT) test results, which may lead to incorrect monitoring of heparin's effects.

Hypersensitivity: Oritavancin is contraindicated in patients with a known hypersensitivity to the drug.

Coagulation Test Interference: In addition to aPTT, oritavancin may interfere with other laboratory coagulation tests, such as prothrombin time (PT) and international normalized ratio (INR), for a limited period following the dose.

There are currently no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) required for this medication.

Question 12

What should I know about Oritavancin and cost?

Accepted Answer

Administration and Billing

Oritavancin is administered as a single dose by a healthcare professional in a medical setting, such as a hospital, clinic, or infusion center. Because it is not a medication you fill at a retail pharmacy, the cost is typically billed through your healthcare provider. The total price often includes the cost of the medication, the facility fees, and the professional fees for the staff administering the infusion.

Insurance Considerations

Most insurance plans, including Medicare and Medicaid, may cover oritavancin when it is medically necessary for treating a skin infection. However, your out-of-pocket costs will vary based on your specific plan's deductible, co-pay, or co-insurance requirements. It is recommended to contact your insurance provider or the billing department of the treatment facility for a cost estimate before receiving the medication.

Financial Assistance

Financial assistance programs may be available for patients who meet certain eligibility requirements. Manufacturers sometimes offer co-pay cards or patient assistance programs to help reduce the cost for those with high out-of-pocket expenses or those without insurance. You can ask your healthcare provider or a social worker at the treatment facility for information on how to apply for these programs.
