What is Cresp 60 mcg?

Cresp 60 mcg (micrograms = 0.001 mg) is an injectable formulation consisting of the drug Darbepoetin alfa. This is a long-acting erythropoiesis-stimulating agent (ESA) that is used in the treatment of anemia caused by various underlying conditions. 

What are the Uses of Cresp 60 mcg?

What are the Dosage Guidelines for Cresp 60 mcg?

The dosage of Cresp 60 mcg is based on the patient’s body weight and 

Anemia due to Chronic Kidney Disease

Recommended dose:

• Patients on dialysis
  • 0.45 mcg/kg of Darbepoetin alfa once a week OR
  • 0.75 mcg/kg of Darbepoetin alfa once every 2 weeks
  • Patients not on dialysis
    • 0.45 mcg/kg of Darbepoetin alfa once every 4 weeks

Maximum dose limit: 

• There is no fixed maximum safe dose. Clinicians must stop the administration of this drug if the patient’s hemoglobin levels rise above 10 or 11

Missed dose instructions:

• Administer the missed dose as soon as possible. Skip this dose if the timing is close to the next dose. 

Overdose instructions:

• In case of an overdose, hemoglobin levels can rise excessively, which can lead to hypertension and thrombosis. In such cases, the drug administration must be stopped, and the patient must be monitored for any adverse reactions.

Chemotherapy-induced anemia

Recommended dose (Subcutaneous administration):

• 2.25 mcg/kg of Darbepoetin alfa once a week OR
• 500 mcg of Darbepoetin alfa once every 3 weeks

Maximum dose limit:

• Discontinue the administration if there is no positive response after 8 weeks.

Missed dose instructions:

• Administer the missed dose as soon as possible. Skip this dose if the timing is close to the next dose. 

Overdose instructions:

• In case of an overdose, hemoglobin levels can rise excessively, which can lead to hypertension and thrombosis. In such cases, the drug administration must be stopped, and the patient must be monitored for any adverse reactions.
• Anemia in chronic diseases (selected cases)

Recommended dose:

• 0.45 mcg/kg of Darbepoetin alfa once a week.

Maximum dose limit:

• The lowest effective dose must be used.

Missed dose instructions:

• Take when remembered; skip if near next dose

Overdose instructions:

• In case of an overdose, hemoglobin levels can rise excessively, which can lead to hypertension and thrombosis. In such cases, the drug administration must be stopped, and the patient must be monitored for hypertension and clot-related reactions.

How does Cresp 60 mcg Work?

Chronic kidney disease (CKD) and chemotherapy-induced anemia are both characterized by a decreased rate of red blood cell (RBC) production. In CKD, the kidneys' erythropoietin (EPO) secretion is inadequate. EPO is a glycoprotein hormone that attaches to EPO receptors (EPORs)on the erythroid progenitor cells located in the bone marrow, promoting proliferation, differentiation, and survival of these cells

In the case of chemotherapy-induced anemia, the bone marrow is damaged with cytotoxic (anti-chemotherapy) agents and produces fewer total erythroid progenitor cells, and even fewer of those cells respond to physiological (endogenous) levels of EPO.

Cresp 60 mcg is a synthetic, long-acting structural analogue of EPO. This drug mimics the action of EPO and binds to the EPORs, thus activating the JAK2-STAT5 signalling pathway. This action activates transcriptional processes necessary for cell survival, proliferation, and maturation of RBCs. By restoring the normal erythropoietin signalling pathway, Darbepoetin Alfa increases erythropoiesis (RBC production), increases hemoglobin levels, reduces the need for blood transfusions, and ultimately reverses the anemia.

Red flag symptoms (seek immediate help)

• Chest pain/breathlessness
• Sudden weakness or slurred speech
• Severe headache or vision problems

  • Allergic reaction signs

What are the Precautions Cresp 60 mcg?

• Before administering Cresp 60 mcg, there must be a complete analysis of correct iron, vitamin B12, and folate levels.
• There must be regular monitoring of blood pressure, as this drug can worsen hypertension.
• Keep a minimum gap of 4 weeks between dose adjustments.
• Immediately stop administering the drug if the hemoglobin levels rise above 10-11.
• Discontinue the medication if there is no change in condition after 8 weeks.
• Keep the medication away from sunlight to prevent drug damage.
