Episode Notes (References Below)
- Brand/Generic:
- Generic: Raloxifene (not available)
- Brand: Evista®
- Mechanism of Action
- Selective Estrogen Receptor Modulator (aka SERM)
- Affects some, but not all, of the receptors that are acted upon by estrogen
- Actually blocks, and acts like, estrogen at these sites in order to prevent bone loss (by decreasing resorption and increasing bone mineral density) as well as potentially blocking the effect of estrogen in breast and uterine tissues (where excess estrogen can lead to cancer)

188 Loestrin® 24 Fe (Ethinyl Estradiol & Norethindrone)
Episode Notes (References Below)
- Brand/Generic:
- Generic: Ethinyl Estradiol & Norethindrone
- Brands
- Loestrin®
- Aranella®
- Junel®
- Microgestin®
- Notrel®
- Others (not a complete list)
- Mechanism of Action
- Estrogen and Progestin combination oral contraceptive
- Most of the work is done by the progestin (norethindrone)
- Thickens cervical mucus which prevents sperm penetration
- Slows tubal motility which delays sperm transport
- Induces endometrial atrophy
- Blocks Leutinizing Hormone (LH) surge, which inhibits ovulation
- Also has antimineralocorticoid activity (which results in less water retention/weight gain than other progestins) and is antiandrogenic, making it useful in treating acne vulgaris
- Ethinyl estradiol (estrogen) mainly works to stabilize the endometrial lining and provide cycle control
- But also suppresses the release of follicle stimulating hormone (FSH) from the pituitary, which may aid in blocking the LH surge and help prevent ovulation

Episode Notes (References Below)
- Brand/Generic:
- Generic: Folic Acid
- Brand: Folacin-800 (OTC)
- Folic acid can be found in most, if not all, multivitamins (400 mcg) and prenatal vitamins (1 mg)
- Mechanism of Action
- Folic acid is utilized in the body to form many coenzymes as well as in the maintenance of erythropoiesis, and WBC and platelet production.
- Folic acid can also enhance the elimination of formic acid, which is a toxic metabolite of methanol
- Folic acid deficiency in pregnancy can lead neural tube defects of the fetus
- Because of this, it is important for any woman trying to become pregnant or of child bearing age to get adequate folic acid before becoming pregnant

Episode Notes (References Below)
- Brand/Generic:
- Generic: irbesartan (not available)
- Brand: Avapro®
- Mechanism of Action
- Angiotensin II receptor blocker (ARB)
- So angiotensin II can’t bind to AT1 receptors, so it can’t cause vasoconstriction or aldosterone release
- This results in a decrease in BP, a decrease in the reabsorption of Na and water, and vasodilation of the efferent arteriole of the kidneys, which is considered renal protective
- May also prevents ventricular remodeling and cardiac hypertrophy
- Indication(s) read more…

Note: 165 (Prednisone) and 166 (Lisinopril/Hydrochlorothiazide) have been covered in previous episodes
- Brand/Generic:
- Generic: Enalapril (available)
- Brand: Vasotec®
- Mechanism of Action
- ACE-Inhibitor
- Angiotensin converting enzyme (ACE) normally convert angiotensin I to angiotensin II, which is a potent vasoconstrictor
- ACE-Is blocks this conversion
- This reduction in angiotensin II also leads to reduced aldosterone secretion, which decreases sodium and water reabsorption
- Decreasing angiotensin II and aldosterone also decreases ventricular remodeling, myocardial fibrosis, myocyte apoptosis, cardiac hypertrophy and norepinephrine release
- The decrease in aldosterone can lead to an increase in serum potassium
- Also causes vasodilation of the renal efferent arteriole which can decrease proteinuria (especially in patients with Diabetic nephropathy) and is considered renal protective
