Radioactive Iodine

[tx hyperthyroidism]
only isotope used to treat thyrotoxicosis by emitting beta rays toxic to cells
- an oral solution is rapidly absorpbed, concentrate by the thyroid and incorporated into storage follicles
- the thyroid parenchyma is destroyed within few weeks, goal is to administer enough to result in euthyroid state without precepitating hypothyroidsim

- only used in adults > 35 yo, not during pregnancy or nursing mothers
Propylthiouracil (PTU)*
(a Thiomide)

[tx hyperthyroidism]
compete for oxidized iodide causes decrease in thyroid hormone production
- inhibit thyroid-peroxidase catalyzed reactions, blocking iodine organification (conjugation) and inhibiting synthesis of thyroid hormones
- *Also inhibits peripheral conversion of T4 to T3
- takes 6-8 weeks, do not inhibit release of stored thyroid hormones

- SE: maculopapular pruitic rash with fever, severe agranulocytosis, arthralgias, decrease prothrombin and increased bleeding
- crosses placenta but preferred during pregnancy bc more protein bound and crosses less readily
-not secreted in breast milk
Methiamazole

[tx hyperthyroidism]
compete for oxidized iodide causes decrease in thyroid hormone production
- inhibit thyroid-peroxidase catalyzed reactions, blocking iodine organification (conjugation) and *inhibiting synthesis of thyroid hormones

- does not inhibit T4 to T3 conversion
- SE: maculopapular pruitic rash with fever, severe agranulocytosis, arthralgias
- crosses placenta
-not secreted in breast milk
Levothyroxine [T4]

[tx hypothyroidism]
thyroid replacement must be weighed against risk of precipitating MI
- T4 for GI absorption, entirely bound to plasma proteins
Triiodothyronine [T3]

[tx hypothyroidism]
increased metabolic activity and short half-life makes this less satisfactory for therapy
- only standardized for iodine content and should not be used
Somatropin

[hypothalamic and pituitary drugs]
GH is enhanced by GHRH and inhibited by somatostatin; fail to secrete GH during puberty results in growth retardation most frequently d/t defective hypothalamic release of GHRH

- Somatotropin is a recombinant human growth hormone used for GH replacement therapy
Carbegoline

[hypothalamic and pituitary drugs]
Lactotrophs of AP secrete prolactin which suppresses estrogen synthesis by antagonizing hypothalmic release of GnRH and decreases sensitivity to GnRH

- Cabergoline is a dopamine receptor agonist that can decrease prolactin levels
- used for medical therapy for small prolactinomas
- SE: N/V
Leuprolide

[hypothalamic and pituitary drugs]
A GnRH agonist that is injected once daily
- act as partial agonist in stimulating the secretion of LH and FSH, causing a resulting transient increase in testosterone levels. Subsequently there is a decrease in testosterone d/t a desensitization of GnRH receptors in pituitary
- can be given to men to aid in mgmt of early stage Prostate Cancer which is androgen dependent
Follitropin

[hypothalamic and pituitary drugs]
Hormone Replacement Therapy for in vitro fertilization
- recombinant form of FSH
- stimulates ovulation but may cause ovarian hyperstimulation syndrome
Desmopressin

[Posterior pituitary drug]
ADH stimulates water reabsorption in CD and increases BP
- Desmopressin is an ADH analog and can be used to **treat Neurogenic Diabetes Insipidus (hypothalamic neurons are unable to synthesize ADH
Oxytocin

[Posterior pituitary drug]
peptide hormone known to mediate muscle contraction (milk release during lactation and uterine contraction)
- used to induce labor artificially
