Retacrit

• Retacrit is a biosimilar to epoetin alfa, designed to stimulate red blood cell production.
• It is primarily used to treat anemia associated with chronic kidney disease, chemotherapy, and certain surgical procedures.
• Retacrit works by mimicking the natural hormone erythropoietin, signaling the bone marrow to produce more red blood cells.
• Common side effects can include hypertension, fever, and injection site reactions.
• Patients receiving Retacrit should be closely monitored for blood pressure and hemoglobin levels.

What is Retacrit?

Retacrit is a biosimilar to epoetin alfa, a recombinant human erythropoietin. It is classified as an erythropoiesis-stimulating agent (ESA), meaning its primary function is to stimulate the bone marrow to produce red blood cells. As a biosimilar, Retacrit is highly similar to its reference product in terms of safety, purity, and potency, with no clinically meaningful differences.

The development of biosimilars like Retacrit provides additional treatment options, potentially increasing patient access to important medications. These agents play a vital role in managing anemia, a condition characterized by a deficiency of red blood cells or hemoglobin, leading to reduced oxygen flow to the body’s organs.

What is Retacrit Used For and How Does It Work?

Retacrit is used for the treatment of anemia in several clinical settings. Its primary applications include managing anemia associated with chronic kidney disease (CKD) in both dialysis and non-dialysis patients, anemia caused by myelosuppressive chemotherapy in patients with non-myeloid malignancies, and anemia in patients undergoing certain surgical procedures to reduce the need for allogeneic red blood cell transfusions.

The mechanism of action for Retacrit involves mimicking the natural hormone erythropoietin, which is primarily produced by the kidneys. Erythropoietin binds to receptors on progenitor cells in the bone marrow, stimulating their proliferation and differentiation into mature red blood cells. By administering Retacrit, the body’s red blood cell production is enhanced, thereby increasing hemoglobin levels and improving the oxygen-carrying capacity of the blood. This process helps to alleviate the symptoms and complications associated with anemia, such as fatigue and shortness of breath.

Specific Retacrit uses include:

• Anemia due to Chronic Kidney Disease (CKD)
• Anemia due to myelosuppressive chemotherapy
• Anemia in zidovudine-treated HIV-infected patients
• Reduction of allogeneic red blood cell transfusions in surgery patients

Retacrit Side Effects and Patient Information

Like all medications, Retacrit can cause Retacrit side effects, which vary in severity and frequency. Common side effects may include hypertension (high blood pressure), fever, headache, rash, and injection site reactions such as pain or redness. More serious, though less common, side effects can include an increased risk of serious cardiovascular events like heart attack, stroke, and blood clots, especially when hemoglobin levels are targeted too high. Pure red cell aplasia (PRCA), a condition where the body stops producing red blood cells, is a rare but severe side effect.

Comprehensive Retacrit patient information emphasizes the importance of careful administration and monitoring. Patients should be educated on the correct method of subcutaneous injection if self-administering, and the importance of adhering to prescribed dosages. Regular monitoring of hemoglobin levels is crucial to ensure the medication is effective and to avoid potential risks associated with excessively high hemoglobin. Blood pressure should also be monitored regularly, as hypertension is a common side effect that may require management. Patients should report any unusual symptoms, such as chest pain, sudden weakness, or vision changes, to their healthcare provider immediately. It is vital for patients to discuss their full medical history with their doctor before starting Retacrit, especially if they have a history of uncontrolled hypertension, seizures, or cancer.
