Pinote decrease level and the increase level or the extra circulatory growth hormone. Growth Hormone Analogue SOMATROPIN MOA: stimulates growth of essentially all tissues of the body mostly the bone Drug of choice for a child with growth failure due to inadequate secretion of endogenous growth hormone & dwarfism Growth Hormone Suppressant Drugs If a person is deficient with growth Indications: patients with excess hormone we will be providing growth secretion of growth hormone, hormone analogue. gigantism, acromegaly Tyrion Lannister, a very famous actor 1. GH receptor antagonist diagnosed with dwarfism 2. Somatostatin analogues Drug example for growth hormone 3. Dopamine agonists analogue: Somatropin Contraindicated to pediatric patients with Prader-Willi Syndrome, those with severe respiratory impairment, those patients taking corticosteroids, because this inhibits the effect of somatropin, those patients taking antidiabetic drugs because your somatropin enhances the efficacy of antidiabetic drugs which leads to 1. GH Receptor Antagonist hypogylycemia Pegvisomant Take note: once final height is MOA: blocks GH receptor site achieved therapy should be Side effects (s/e): hyperhydorsis, discontinued cephalgia, fatigue Side effects (s/e): arthralgia, Adverse effects(a/e): chest pain, myalgia, peripheral edema, weakness hypertension, elevated hepatic paresthesia, cephalgia transaminase Adverse effects (a/e): seizures, intracranial hypertension, and leukemia Nursing Care of Clients with Drugs related to the Endocrine System, Women and Men’s Health Mr. Jetier T. Pinote Growth hormone drugs should not be given orally however for bromocriptine mesylate since it does not entirely focus on the growth hormone and only has an effect on it that is why this medication can be given oral formulation. Side effects(s/e): nausea, anorexia, dyspepsia, serostomia Growth Hormone Suppressant Drugs Adverse Effects (a/e): 2. Somatostatin Analogues hypertension, myocardial infarction, stroke seizure Lanreotide Acetate MOA: prevents pituitary gland secrete growth hormone The effect is dependent on the dose given The dose will be calculated by the physicians Depot formulation (meaning it is a slow release form of medication to permit less frequent administration of medication) Last for 28 days after deep subcutaneous injection Thyroid-Stmulating Hormone For the same reason that this MOA: stimulates thyroid gland to medication is given every 4 weeks. release T3 (triiodothyronine) and T4 Side effects(s/e): Diarrhea, (thyroxine) abdominal pain, nausea & vomiting, Used as diagnostic agent to constipation, weight loss, and differentiate between primary and flatulence secondary hypothyroidism Indicated to patients with thyroid cancer 0.9 mg IM (intramuscular) gluteus maximum, and 2nd dose is given after 24 hrs This medication is given to the patient and then lab works will be done. Growth Hormone Suppressant Drugs Primary Hypothyroidism: If there is an increase of your TSH level. Dopamine Agonists Secondary Hypothyroidism: If Bromocriptine mesylate there is still a very low TSH. MOA: inhibits the secretion of GH This is indicated to patients with caused by tumor in pituitary gland thyroid cancer. Available in oral formulation Nursing Care of Clients with Drugs related to the Endocrine System, Women and Men’s Health Mr. Jetier T. Pinote Pituitary Gland 2. Posterior Lobe Aka neurohypophysis Secretes the following hormones: Antidiuretic hormone(ADH)/ vasopressin Adrenocorticotropic Hormone Oxytocin A hormone released by pituitary corticotrophs Stimulates the release of glucocorticoids (cortisol), Antidiuretic Hormone mineralocorticoids (aldosterone), and Decrease of your ADH or which with androgen term as the diabetes insipidus as the Secretion follows a diurnal rhythm disorder or the increase of the ADH or (meaning the secretion is higher in the your SIADH or the syndrome of morning and decreases throughout the inappropriate antidiuretic hormone or day) an increase level of your ADH. 1. Cosyntropin Diabetes Insipidus A synthetic ACTH Decreased amount of circulating MOA: stimulates production of and Antidiuretic Hormone release of cortisol, corticosterone, and Excessive urination which leads to androgens severe dehydration and electrolyte loss Used for diagnostic purposes to Kidney tubules fail to reabsorb water differentiate between pituitary and S/S: Excretion of large amounts of adrenal cause of adrenal insufficiency dilute urine, polydipsia, dehydration, Given via IM (intramuscular) or IV inability to concentrate urine which (intravenous) routes again is manifested with dilute urine, CAUTION: patients receiving diuretics low urine specific gravity Antidiuretic Hormone Therapy Drugs since this medication increases MOA: promotes water reabsorption from electrolyte loss the renal tubules S/e: Peripheral edema Contraindication: Patients with renal A/e: bradycardia, hypertension, sinus, disease tachycardia Drug Ex.

Pinote Drug interactions: - Increases the potency of drugs taken concurrently, including aspirin and NSAIDs, thus increasing the risk of bleeding - Use of K-wasting diuretic increases potassium loss Administration of glucocorticoid drugs Indications: Trauma, surgery, inflammation, emotional upsets, anxiety When therapy is discontinued, the dose should be tapered to allow the adrenal cortex to produce cortisol and other corticosteroids. Abrupt withdrawal of the drug can result in severe adrenocortical deficiency. Fludrocortisone MOA: promotes reabsorption of sodium from the renal tubules Given orally with a glucocorticoids A/e: fluid overload, hypertension Mineralocorticoid deficiency usually occurs with glucocorticoid deficiency, called corticosteroid deficiency. Endocrine System, Women and Men’s 4. Gestation Is because of Health al the increasing Diabetes level of Diabetes Mellitus progesterone, cortisol, and Normally when we eat carbohydrates your human body turns into a sugar called your glucose, placental and sends that to your blood stream. Your lactogen to pancreas releases insulin, it is a hormone check her that helps move glucose from your blood into during the your cell and then the cell uses that glucose second to third for energy. trimester. The increase of When you have diabetes and don’t get the the hormones proper treatment, your body doesn’t use leads to the insulin like it should. Too much glucose stays inhibition of in your blood a condition called your high insulin usage. blood pressure or your hyperglycemia. To define Diabetes Mellitus simply: Differentiation of a healthy Type 1 DM Chronic Disease of the pancreas that and type 2 DM results from deficient glucose metabolism. Caused by insulin secretion insufficiency Can’t be cured but, it can be controlled Types of Diabetes 1. Type 1 2. Type 2 3.
