-sterols and stanols equally effective

17
Q

Ephedra MOA

A

Alkaloid constituents of the plant: ephedrine, pseudoephedrine, and small amount of phenylpropanolamine

Ephedrine and pseudoephedrine are non-selective alpha and beta receptors agonist which stimulate nervous system

18
Q

Ephedra use/efficacy, adverse rxns

A
  • weight loss

- 0.9 kg/mo up to 6 mo with

19
Q

Bitter orange: MOA, adverse effects, caution in?

A

MOA:
contains 1-6% of synephrine which is related to ephedrine
-Adverse effects: same as ephedra
-Caution in: HTN, CV pts

20
Q

Bitter orange clinical pearls

A
  • manufacturers switch to this after ban on ephedra
  • often contain caffeine
  • GRAS
  • no evidence that this supplement is safer than Ephedra!!
21
Q

Calcium

A
  • pts with low Ca intake often gain more weight and have a higher BMI
  • Efficacy: 800-1200 mg qd Ca supplement have been shown to increase weight reduction and body fat loss
  • 800-900 mg qd has shown wt loss of 8-9 kg

Adverse rxns: belching, flatulence

**supplement alone does not equal to a low fat dietary intake of calcium

22
Q

Alli (Orlistat) MOA, efficacy, adverse rxns

A
  • reversible inhibitor of pancreatic and gastric lipase
  • efficacy: FDA approved for long term weight loss
  • effects in BMI greater than 27

23
Q

Alli: dosing, drug interactions, clinical pearls

A
  • 60mg tid with each meal that contains fat
  • drug interactions: anticoagulants, amiodarone, levothyroxine, and vitamins

  • due to risk of liver injury, inform pt signs/sx
24
Q

Diabetes tx options

A

chromium

vanadium

25
Chromium MOA
Might reduce oxidative stress Low levels are associated with impaired glucose & insulin Chromium 0 has no activity Chromium III found in food and supplements Chromium VI used in welding industries & carcinogenic Several salt forms: picolinate, nicotinate, polynicotinate, and chloride - Chromium picolinate form most often used in studies - caution in renal deficiency - mixed data and effectiveness - no reliable method to dx efficacy
26
Chromium adverse reactions and dosage
HA, insomnia, irritability, mood changes & sleep disturbance Vomiting, diarrhea, and hemorrhage Dosage: 200-1000 mcq divided doses -0.4-2.5% absorbed and rapidly excreted in urine
27
interactions w/ chromium
Herbs: bilberry, brewer yeast, iron, Vit. C and zinc Drugs: insulin, levothyroxine, NSAIDs & corticosteroid Disease: diabetes, renal dysfunction
28
MOA Vanadium
Activates insulin receptor proteins, stimulates glucose oxidation and transport Liver: stimulates glycogen synthesis Adipose: inhibits lipolysis Skeletal muscle: promotes glucose uptake
29
Efficacy of vanadium and adverse rxns
efficacy: High dose of 100 mg qd may improve insulin sensitivity and possibly reduce blood glucose levels Effective in Type 2 but not Type I diabetes Adverse reactions: GI upset, kidney toxicity, fatigue, lethargy & tongue discoloration
30
Vanadium interactions/pearls
Dosage: 50 mg bid of the sulfate form Interactions: Herbs: garlic, ginger, ginkgo & ginseng Drugs: anticoagulants and antiplatelets Disease: diabetes and renal dysfunction Clinical pearls: Average diet contains 6-18 mcq qd Only 5% is absorbed
31
Garlic indications, MOA
indications: HTN, hyperlipidemia MOA: Allicin is the active ingredient Inhibits hepatic cholesterol synthesis Activates production of endothelium-derived relaxation factor to relax smooth muscle and vasodilation
