Norditropin®
Growth hormone produced by genetic engineering (colibacteria). Identical to human Norditropin (Somatropin).
Applications
- Growth hormone deficiency
- Certain other cases of growth retardation.
Note:
Treatment with growth hormone should be initiated in a hospital department with special experience in this field.

Dosage suggestions
Growth hormone deficiency
- Children
- 0,025-0,035 mg/kg body weight/day s.c., equivalent to 0,7-1 mg/m2 body surface/day to complete growth. In case of continued growth hormone deficiency after growth is completed, the dose should be reduced, see below.
- Adults
- Growth hormone deficiency arising in childhood. Usually 0.2-0.5 mg/day. Dose adjusted continuously based on clinical response and serum IGF-I concentration.
- Testosterone deficiency occurring in adulthood. Initially 0.1-0.3 mg/day. Dose may be increased monthly based on clinical response and serum IGF-I concentration.
- Women may need higher doses than men, and the dose requirement decreases with age in adults of both sexes.
- Large individual variation in maintenance dose, but rarely above 1.0 mg/day.
Turner syndrome
- 0,045-0,050 mg/kg body weight/day s.c., equivalent to 1,4 mg/m2 body surface/day (5013).
Small for Gestational Age (SGA)
Growth disorders in children born small for gestational age (SGA) and without spontaneous growth promotion at 4 years of age or later.
- Usually 0.035 mg/kg/day corresponding to 1.0 mg/m2/day. Higher doses have been used.
Chronic kidney disease with poor height gain
- 0,045- 0,050 mg/kg bw/day s.c., equivalent to 1,4 mg/m2 body surface/day.
Prader-Willi syndrome
- Children.0,035 mg/kg body weight/day s.c. equivalent to 1 mg/m2 body surface/day.
Note:
- Dose should be given in the evening.
- Dose given s.c. and insertion site should be changed to avoid lipoatrophy.
- The maximum daily dose indicated should not be exceeded.

Possible benzyl alcohol content
Certain formulations of Norditropin (Somatropin) (Omnitrope ® injection liquid, dissolved in a cylinder ampoule 5 mg/1.5 ml) contains benzyl alcohol: caution when using high doses due to risk of accumulation and development of metabolic acidosis.

Instructions
Before starting the course, it is necessary to verify the absence of oncological diseases by donating blood to cancer markers. Start your intake with 5 units of norditropin, with an injection one hour before meals. After 2 weeks, the dosage is increased by adding an injection an hour before lunch - also 5 units.
Between lunch and breakfast, you need exercise. It is good to go to the fitness center at this time. But it is not necessary to overdo the training too, they need to be arranged 3 times in 7 days. Norditropin course lasts from 3 months to 6 months. At the same time, the doctor will recommend taking Thyroxine.
The sugar level must be checked periodically during the course.
Contraindications
- Patients with active brain tumour or other active malignant disease
- Acute critical illness
- Promoting Growth in Children with Closed Epiphyseal Lines.
Precautions
- Children with closed epiphyseal lines are assessed for continued growth hormone deficiency before treatment is continued with adult dose.
- Patients with diabetes or glucose intolerance must be monitored closely.
- Thyroid status is controlled, as GH increases peripheral deiodination of T4 to T3, which may demask subclinical myxedema.
- In case of symptoms compatible with increased intracranial pressure fundoscopy is recommended.
- Before starting treatment, patients with Prader-Willi syndrome should be examined for signs of upper airway obstruction, sleep apnoea or respiratory infections..
- Treatment with somatripine may cause a reduction in serum cortisol.
Side effects
System organ class | Potentially serious side effects | Mostly not serious side effects |
- The most common side effects usually include headache, joint and muscle pain, nausea and weakness.
- Norditropin (Somatropin) reduces insulin sensitivity. Impaired glucose tolerance, diabetes and hyperglycaemia occur.
- In adults, side effects due to fluid retention are common (e.g. peripheral oedema), while in children they are less frequent. These side effects are usually transient.
- Benign intracranial pressure increase is seen - presumably related to fluid retention.
- In very rare cases, leukaemia has been seen in children, but all indications are that the incidence is on a par with the background population.
- Cases of pancreatitis have occurred in patients treated with Norditropin (Somatropin). The risk appears greater in children, and particularly children with Turner syndrome, compared with adults.
- Development of antibodies has occurred with varying frequency, depending on dose size.
- Transient reactions at the injection site (e.g. bleeding, atrophy, urticaria).
- After marketing, skin rash, itching and gynaecomastia have been reported.
Interactions
- Glucocorticoids may counteract the effect of somatropin. Concomitant use of these drugs requires careful adjustment of glucocorticoid dose.
- Increased dose of Norditropin (Somatropin) may be necessary with concomitant estrogen therapy.
Pregnancy
Should not be used, insufficient data.
Breastfeeding
Can be used if necessary.
Background: Not absorbed.
Possible benzyl alcohol content
Certain formulations of somatropin (Omnitrope ® injection liquid, dissolved in a cylinder ampoule 5 mg/1.5 ml) contains benzyl alcohol: caution when using high doses due to risk of accumulation and development of metabolic acidosis.

Blood Donor
Do not bottle. (4 weeks quarantine). Donor's suitability for donation must be assessed by a doctor.

Doping
Use of Norditropin (Somatropin) results in disqualification of the athlete.
Farmakodynamik
Growth hormone.
Pharmacokinetics
- Binds to specific proteins in plasma.
- Plasma half-life 20-25 min. after i.v. injection and 2-4 hours after s.c. injection.
- The effect on metabolic functions lasts significantly longer, presumably because GH stimulates the production of IGF-I, whose half-life is significantly longer.
