Pharmacology Flashcards
Growth hormone analog used in growth hormone deficiency
Somatropin
Somatostatin analog used for acromegaly, carcinoid, glucagonoma and other growth hormone-producing pituitary tumors
Octreotide
Gonadotropin-releasing hormone analog used for infertility (pulsatile administration) or suppression of gonadotropin production (continuous administration)
Leuprolide
Competitive antagonists at gonadotropin releasing hormone receptors used to prevent LH surge during controlled ovarian hyperstimulation
Ganirelix
Ergot dopamine agonist used to suppress prolactin release
Bromocriptine
Synthetic human corticotropin used for diagnosis of adrenal insufficiency
Cosyntropin
Agent used to stimulate uterine contraction and labor, milk letdowns, and control postpartum bleeding
Oxytocin
Agent of choice for the treatment of hypothyroidism
Levothyroxine (T4)
An isomer of T3 which may be used in myxedema coma
Liothyronine (T3)
Thioamide agents used in hyperthyroidism
Methimazole and propylthiouracil (PTU)
Thioamide less likely to cross placenta, inhibits peripheral conversion of T4 to T3 in high doses, and indicated for pregnant women in 1st trimester
Propylthiouracil (PTU)
Propylthiouracil (PTU) mechanism of action
Inhibits thyroid peroxidase
Can be effective for short term therapy of thyroid storm, but after several weeks of therapy causes an exacerbation of hyperthyroidism
Iodide salts (potassium iodide)
Permanently cures thyrotoxicosis, patients will need thyroid replacement therapy thereafter. Contraindicated in pregnancy
Radioactive iodine
Used for the symptomatic treatment of thyrotoxicosis by blocking cardiac adverse effects
Propranolol and Esmolol
Used for Addison’s disease, congenital adrenal hyperplasia inflammation, immune suppression, and asthma
Glucocorticoids
Two short-acting glucocorticoids
Hydrocortisone (cortisol), cortisone
Four intermediate-acting glucocorticoids
Prednisone, Prednisolone, Methylprednisolone and Triamcinolone
Two long-acting glucocorticoids
Betamethasone, dexamethasone
Mineralocorticoids
Fludrocortisone and deoxycorticosterone
Side effects of corticosteroids
Iatrogenic Cushing’s syndrome, hyperglycemia, impaired wound healing, osteoporosis, peptic ulcers, myopathy, adrenal suppression (> 2 week treatment)
Inhibits conversion of cholesterol to pregnenolone therefore inhibiting corticosteroid synthesis
Aminoglutethimide
Antifungal agent used to inhibit adrenal and gonadal steroid synthesis
Ketoconazole
Selective inhibitor of 11-hydroxylation and interferes with cortisol and corticoterone synthesis; used for adrenal function tests and is the only adrenal-inhibiting medication that can be administered to pregnant women with Cushing’s syndrome
Metyrapone
Glucoroticoid receptor antagonist that is used as an antiabortifacient due to its strong antiprogestin activity
Mifepristone (RU486)
Three rapid-acting insulin used for postprandial glycemia
Aspart, lispro, glulisine
