Ngenla 72IU by Pfizer is a long-acting growth hormone analog containing somatrogon-ghla, a recombinant protein designed for once-weekly administration. Each pre-filled injection pen contains 24 mg of somatrogon in 1.2 ml of solution. Unlike conventional somatropin HGH products, Ngenla uses a long-acting formulation that activates growth hormone receptors. The product is supplied as one pre-filled pen and is intended for prescribed treatment of pediatric growth hormone deficiency. The legacy 72IU designation is used for catalog identification; the official manufacturer strength is expressed in milligrams (24 mg/1.2 ml).
Ngenla Pen 72IU: Pfizer Somatrogon Product Overview
Ngenla Pen 72IU is a legacy catalog designation for the Pfizer Ngenla 24 mg/1.2 ml prefilled injection pen containing somatrogon-ghla, a long-acting recombinant human growth hormone analog. Unlike conventional somatropin products, Ngenla contains somatrogon, a modified growth hormone molecule designed for once-weekly administration.
Each Ngenla prefilled pen contains 24 mg of somatrogon-ghla in 1.2 ml of solution, providing a concentration of 20 mg/ml. Pfizer identifies the product strength in milligrams rather than international units (IU).
The historical "72IU" designation is retained on this page for catalog identification. It should not be interpreted as an official Pfizer strength or a direct conversion to somatropin IU.

Ngenla Active Ingredient: Somatrogon-ghla
The active ingredient in Pfizer Ngenla is somatrogon-ghla, a long-acting recombinant growth hormone analog.
Somatrogon contains a modified human growth hormone structure designed to extend its duration of activity compared with conventional daily somatropin formulations.
Somatrogon interacts with growth hormone receptors and influences downstream insulin-like growth factor 1 (IGF-1) signaling, which is involved in physiological growth regulation.
Ngenla is used in prescribed treatment of pediatric growth hormone deficiency. Approved age ranges and indications may vary by country.

Ngenla 24 mg vs Ngenla 60 mg: Presentation and Comparison
Pfizer manufactures Ngenla in two prefilled pen strengths: 24 mg/1.2 ml and 60 mg/1.2 ml.
Ngenla 24 mg/1.2 ml
- Active ingredient: Somatrogon-ghla
- Total strength: 24 mg
- Concentration: 20 mg/ml
- Volume: 1.2 ml
- Dose increments: 0.2 mg
- Maximum single injection: 12 mg
- US pen color identification: Lilac
Ngenla 60 mg/1.2 ml
- Active ingredient: Somatrogon-ghla
- Total strength: 60 mg
- Concentration: 50 mg/ml
- Volume: 1.2 ml
- Dose increments: 0.5 mg
- Maximum single injection: 30 mg
- US pen color identification: Blue
Both products contain somatrogon-ghla but differ in total strength, concentration, dose increments and pen identification.
The legacy catalog labels "72IU" and "180IU" are not official Pfizer dosing units and should not be used as a direct conversion between somatrogon and somatropin.
Ngenla Somatrogon vs Conventional Somatropin HGH
Ngenla and conventional somatropin medications both act on the growth hormone signaling pathway, but they contain different active substances.
Somatropin is a recombinant form of human growth hormone commonly used in daily injection formulations.
Somatrogon-ghla is a modified long-acting growth hormone analog designed for once-weekly treatment.
Differences in molecular structure, pharmacokinetics and dosing schedules mean that milligram quantities of Ngenla should not be directly compared with somatropin IU values.
Ngenla Clinical Use and Growth Hormone Deficiency
Pfizer Ngenla is a prescription medication indicated in the United States for pediatric patients aged 3 years and older with growth failure caused by inadequate secretion of endogenous growth hormone.
The medication is administered by subcutaneous injection on a once-weekly schedule under the supervision of an appropriately qualified healthcare professional.
Individual treatment requirements depend on the patient's diagnosis, body weight, treatment response and clinical monitoring.
The total amount contained in the pen is not an individual treatment dose.
Ngenla 24 mg Storage and Handling
Ngenla is a temperature-sensitive biological medication requiring refrigerated storage between 2°C and 8°C.
According to Pfizer's US prescribing information:
- Store refrigerated at 2°C–8°C before first use.
- Keep the pen in its original carton to protect it from light.
- Do not freeze or shake.
- After first use, refrigerate between uses.
- The pen may be used for up to 28 days after first use when handled according to the official instructions.
- Remove and safely discard injection needles after each use.
Follow the manufacturer instructions applicable to the specific pen and market.
Ngenla Somatrogon Safety and Precautions
Somatrogon is a biologically active hormone analog that requires medical supervision and appropriate clinical monitoring.
Potential adverse reactions associated with Ngenla include injection-site reactions, headache, fluid retention and other treatment-related effects.
Important contraindications and precautions are described in Pfizer's official prescribing information, including active malignancy, certain acute critical illnesses, severe diabetic retinopathy and other medical conditions.
Patients should follow their prescribing healthcare professional's recommendations and the official product instructions.
