• Instruct patient to take drug before bedtime to lessen GI upset. Tell him to call prescriber if he can't maintain his usual diet because of GI upset.
• Inform patient using nasal spray that runny nose, sneezing, and nasal irritation may occur during first several days as he adjusts to spray.
• Instruct patient to bring nasal spray to room temperature before using.
• Advise patient to blow nose before using spray, to take intranasal dose as one spray in one nostril daily, and to alternate nostrils with each dose.
• Tell patient to discard unrefrigerated bottles of calcitonin (salmon) nasal spray after 30 days.
• Encourage patient to consume a diet rich in calcium and vitamin D.
• As appropriate, review all other significant adverse reactions and interactions, especially those related to the drugs mentioned above.

The secretion of hypothalamic, pituitary, and target tissue hormones is under tight regulatory control by a series of feedback and feed- forward loops. This complexity can be demonstrated using the growth hormone (GH) regulatory system as an example. The stimulatory substance growth hormone releasing hormone (GHRH) and the inhibitory substance somatostatin (SS) both products of the hypothalamus, control pituitary GH secretion. Somatostatin is also called growth hormone-inhibiting hormone (GHIH). Under the influence of GHRH, growth hormone is released into the systemic circulation, causing the target tissue to secrete insulin-like growth factor-1, IGF-1. Growth hormone also has other more direct metabolic effects; it is both hyperglycemic and lipolytic. The principal source of systemic IGF-1 is the liver, although most other tissues secrete and contribute to systemic IGF-1. Liver IGF-1 is considered to be the principal regulator of tissue growth. In particular, the IGF-1 secreted by the liver is believed to synchronize growth throughout the body, resulting in a homeostatic balance of tissue size and mass. IGF-1 secreted by peripheral tissues is generally considered to be autocrine or paracrine in its biological action.

Epinephrine acts by binding to a variety of adrenergic receptors . Epinephrine is a nonselective agonist of all adrenergic receptors, including the major subtypes α 1 , α 2 , β 1 , β 2 , and β 3 . [59] Epinephrine's binding to these receptors triggers a number of metabolic changes. Binding to α-adrenergic receptors inhibits insulin secretion by the pancreas , stimulates glycogenolysis in the liver and muscle , [60] and stimulates glycolysis and inhibits insulin-mediated glycogenesis in muscle. [61] [62] β adrenergic receptor binding triggers glucagon secretion in the pancreas, increased adrenocorticotropic hormone (ACTH) secretion by the pituitary gland , and increased lipolysis by adipose tissue . Together, these effects lead to increased blood glucose and fatty acids , providing substrates for energy production within cells throughout the body. [62]

The term peptide has been used to mean secretagogue peptides and peptide hormones in sports doping matters: secretagogue peptides are classified as Schedule 2 (S2) prohibited substances on the World Anti-Doping Agency (WADA) Prohibited List, and are therefore prohibited for use by professional athletes both in and out of competition. Such secretagogue peptides have been on the WADA prohibited substances list since at least 2008. The Australian Crime Commission cited the alleged misuse of secretagogue peptides in Australian sport including growth hormone releasing peptides CJC-1295 , GHRP-6 , and GHSR (gene) hexarelin. There is ongoing controversy on the legality of using secretagogue peptides in sports. [26]
