Sermorelin essentially mimics the hypothalamic peptide, GHRH. Sermorelin acts directly on the pituitary stimulating the somatotroph cells ability to produce and secrete GH.13 Sermorelin increases proliferation of somatotroph cells during development.13 With the increase of serum GH, downstream effects occur. A notable hormone that is commonly used as a surrogate for growth hormone therapy, insulin like growth factor 1 (IGF-1), is known to increase with the administration of Sermorelin. IGF-I negatively regulates GHRH-mediated GH secretion.14
Sermorelin is able to influence the concert of hormonal signaling that effects the GH axis. GH secretion from the anterior pituitary is regulated by GHRH, somatostatin, and GH secretagogues. The positive and negative opposing regulation of growth hormone by GHRH and somatostatin creates a rhythmic-circadian GH secretion. GH asked by signaling target cells, most notably increasing the synthesis of IGF-1 in the liver and peripheral tissues.13
Sermorelin acts on the growth GHRHr in the pituitary to regulate cellular actives. GHRHr is the natural receptor for the endogenous hormone GHRH, a signaling hormone produced by the hypothalamus. This receptor among many other functions, controls growth hormone release, mainly by inhibition of somatostatin activity.15
Tell your doctor of all prescription and nonprescription medication you may use, especially: corticosteroids and thyroid medications. This drug may affect the results of certain lab tests (e.g., inorganic phosphorus, alkaline phosphatase). Make sure laboratory personnel and your doctors know you use this drug. Do not start or stop any medicine without approval from your healthcare provider. Hypothyroidism: Untreated hypothyroidism can jeopardize the response to Sermorelin. Thyroid hormone determinations should be performed before the initiation and during therapy. Thyroid hormone replacement therapy should be initiated when indicated. Intracranial lesions: Patients with GH deficiency secondary to an intracranial lesion were not studied in clinical trials; Sermorelin treatment is not recommended in such patients. Obesity, hyperglycemia or hyperlipidemia: Subnormal GH responses have been seen in obesity and hyperglycemia, and in patients with elevated plasma fatty acids.
FDA pregnancy risk category C. Exercise caution during lactation; it is not known if this drug is excreted in breast milk. Laboratory Tests: Serum levels of inorganic phosphorus, alkaline phosphatase, GH and IGF-I may increase with therapeutic use. Corticosteroids: Glucocorticoids may inhibit the response to Sermorelin. Controlled studies did not indicate an interaction of Sermorelin with drugs commonly used in the treatment of routine pediatric problems/illnesses. However, formal drug interaction studies have not been conducted
Call your doctor for medical advice if pain/swelling/redness occurs at the injection site (occurring in approximately 16% of patients). Other possible, but less common side effects of rhGH (not Sermorelin) are upper respiratory conditions, nerve sensitivity, insomnia, depression, nausea, hypothyroidism chest pain, gynecomastia, headache, flushing, dysphagia, dizziness, hyperactivity, somnolence, urticaria and sore bones. Call your health care provider immediately if you are experiencing trouble swallowing, vomiting, and tightness in the chest. Antibody formation to Sermorelin has been reported after chronic subcutaneous administration of large doses but their clinical significance is unknown. Antibodies do not appear to affect growth hormone release nor appear to be related to a specific adverse drug reaction profile. No generalized allergic reactions have been reported. A temporary allergic reaction described by severe redness, swelling and urticaria at the injection sites has been reported in one patient who developed antibodies. Additionally, its use may reduce insulin sensitivity, thereby raising blood sugar to levels which could be harmful to diabetes sufferers. It may also decrease triiodothyronine (T3) levels due to its tendency to reduce the bodily levels of sodium, potassium, and phosphorous.
