Cebranopadol Dosing Calculator

Dose

200, 400, or 600 mcg orally once daily. Dose titration during initial weeks to target dose, followed by maintenance period.

Frequency

Once daily oral administration

Duration

14 weeks (titration + maintenance)

Higher doses (600 mcg) associated with more adverse events during titration. Patients reaching target doses had acceptable tolerability. Adverse event incidence during maintenance was 10% or less for individual events.

How much bacteriostatic water should I add to a 5 mg vial of Cebranopadol?

The community standard is 2 mL of bacteriostatic water for a 5 mg Cebranopadol vial. That gives a concentration of 2.50 mg/mL, so a 400 mcg dose is 16 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 5.00 mg/mL and halves the draw to 8 units. Less water = smaller injection volume but harder to measure precisely.

How many syringe units is a 400 mcg dose of Cebranopadol?

On a standard U-100 insulin syringe, a 400 mcg dose of Cebranopadol is 16 units when the 5 mg vial is reconstituted with 2 mL of bacteriostatic water (2.50 mg/mL). If you use 1 mL of bac water instead, draw 8 units (5.00 mg/mL).

What is the standard Cebranopadol dose?

Clinical protocols for Cebranopadol typically use 400 mcg–2 mcg once daily via subcutaneous injection. 400 mcg is a common starting dose. Protocol used in ALLEVIATE-1 (abdominoplasty) and ALLEVIATE-2 (bunionectomy) Phase 3 trials. No titration required for acute use.

How long does a vial of Cebranopadol last at 400 mcg once daily?

A 5 mg vial of Cebranopadol contains roughly 12 doses at 400 mcg per injection. At once daily dosing, that is approximately 12 days (about 2 weeks) of supply per vial. Reconstituted Cebranopadol should generally be used within 28 days when refrigerated.

Where do you inject Cebranopadol?

Cebranopadol is typically administered subcutaneously. Common subcutaneous sites are the lower abdomen (at least an inch from the navel), the outer thigh, and the love handles. Rotate sites with each injection to reduce localized irritation and bruising.

Can I use sterile water instead of bacteriostatic water for Cebranopadol?

Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Cebranopadol because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
