Lar,
Thanks for the info. Let me know how things work out. Good luck.

All the substances absorbed across the gut wall enter the portal circulation, and pass through the liver before moving on to the body. Liver enzymes readily degrade selegiline, as do enzymes in the gut wall. In effect, sublingual doses are more potent because more parent selegiline is available to the brain. But that brings up a possibly contentious issue.

Depending on your genetic makeup, your total MAO and the ratio of MAO-A to MAO-B can vary substantially. Some people might be very sensitive to tyramine, even though the total dose of selegiline is low. You can't assume that you will not have a tyramine reaction, even at 5 or 10 mg.
