- MAOIs -- Monoamine Oxidase Inhibitors.
-
- They are antidepressants which are effictatious in the treatment of
- atypical depression (vegitative symptoms, anxiety, initial insomnia,
- etc), panic disorder, anxiety and (recently discovered) borderline
- personality disorder.
-
- MAO metabolizes serotonin, norepinephrine and dopamine. By inhibiting
- this, MAOIs increase levels of those neurotransmitters. Phenelzine (Nardil)
- and tranycypromine (Parnate) are the two popular MAOIs. moclobemide
- (Aurorex -- called something else in canada) is a recently introduced
- MAOI which is slightly different and apparently not as effictatious, although
- it eliminates the hazards associated with the earlier MAOIs.
-
- Tyramine is an amino acid which is normally metabolized by MAO in the
- gut. After taking tranylcypromine or phenelzine (but not, apparently,
- moclobemide) this MAO is inhibited and any dietary Tyramine will not be
- metabolized and will cause an increase in tyramine levels in blood. This
- is bad due to tyramine's effect on norepinephrine and leads to a
- hypertensive crisis. Blood pressure goes up to 180+ over something,
- heartbeat goes to well over 100 bpm, and people who suffer one of these
- typically report getting the most painful headache of their lives. Sometimes
- a Ca-blocker like nifedipine is prescribed for the user of the MAOI to
- take to combat this effect should it occur.
-
- Tyramine is in cheese, wines, and anything aged or fermented. Also,
- symptathomimetic drugs (MDMA, amphetamines, OTC cold meds like ephedrine,
- dextromethorphan, etc) can cause a hypertensive crisis.
-
- MDMDA, LSD, EtOH, chocolate, yohimbine, etc, etc, etc are *not* MAOIs. At
- least they are not MAOIs in any way which would be useful to discuss in
- this context without giving a thesis that i really don't feel like writing
- tonight... For the purposes of 99.9% of the people reading this message,
- and based on the description i've givin above of MAOIs, they are not MAOIs.
- These are the chemicals to avoid when you are on a MAOI. People have
- a tendency to confuse these two categories.

- Just a note to add to the very clear explanation from Lamont Granquist.
- Some drugs such as the South American tribespeople's Ayahuasca or Yage
- contain a mixture of two plants, one containing DMT and the other the
- inhibitor which prevents the DMT from being metabolised. So, for the
- reasons given by Lamont, it could be dangerous to mix Ayahuasca with
- MDMA. And I have heard that seesions involving just that mixture have
- been on offer in California.

-
- This is something I got from a nutritionist at the local student health
- center, which answers some of the questions one might have about MAO
- -inhibitors.
- Since I don't know the book this comes from, it's of course being
- presented without the author's permission. Sorry :-)

- Low-Tyramine Diet
- Purpose: To prevent the onset of adverse reactions such as severe headaches,
- tachycardia, and hypertensive attacks by persons receiving monoamine
- oxidase (MAO) therapy and consuming foods high in tyramine content.
- Use: This diet is used to assist counseling of persons receiving
- monoamine oxidase (MAO)inhibitors for treatment of anxiety and
- depression. Foods containing small amounts of tyramine
- (<6 mg) can cause a mild crisis, while consumption of foods high in
- tyramine (10-25 mg) can produce severe headaches with intracranial
- hemorrhage and acute hypertensive attacks.
- The foods listed with moderate to low tyramine content should be used
- with caution in limited amounts that do not exceed 5 mg.
- Related Physiology: Tyramine is an amino acid that is formed by the
- decarboxylation of tyrosine, which occurs during the process of
- fermentation, aging, spoiling, or pickling of food.
- Under normal circumstances, the enzyme MAO (monoamine oxidase)
- inactivates tyramine,preventing the release of excess norepinephrine. In
- the presence of MAO inhibitors, tyramine is activated, causing
- norepinephrine to be released from nerve endings. Hypertensive reactions
- and other side effects may occur due to excess release of norepinephrine.
-
- Foods High in Tyramine (to be avoided) :
- All aged/mature cheese
- (exception: cottage cheese, cream cheese)
- Dry and fermented sausage
- (bologna, salami, pepperoni, corned beef, and liver)
- Pickled herring and salted dried fish
- Broad beans and pods
- (lima, fava beans, lentils, snow peas, and soy beans)
- Meat extracts
- Yeast extracts/brewer's yeast
- Beer and Ale
- Red wine
- (chianti, burgundy, sherry, vermouth)
- Sauerkraut
- Banana Peel
-
- Foods Moderate to Low in Tyramine:
- (to be used in limited amounts, i.e., 1/2 cup, 4 oz. or less)
- Fruits
- (bananas, avacados, canned figs, raisins, red plums, raspberries)
- Cultured dairy products
- (buttermilk, yogurt, and sour cream)
- Chocolate
- Caffeine
- (coffee, tea, and cola drinks)
- White wine, port wines
- Distilled Spirits
- Soy sauce
- Peanuts
