MAO-B inhibitors - Parkinson's drugs

EldeprylMAO-B inhibitors are used to treat the symptoms of Parkinson's

They work by preventing the breakdown of dopamine in the brain.

They are used to make levodopa last longer or reduce the amount required.

The generic drug names and brand names are:

  • Selegiline (Eldepryl®, Zelapar®)
  • Rasagiline (Azilect®)

Advantages of MAO-B inhibitors

MAO-B inhibitors may reduce fluctuations in effectiveness of drugs that some people with Parkinson's experience after the first few years.

By itself, selegiline has very few side effects.

Because Zelapar is absorbed better, a smaller dose is needed.

Some disadvantages of MAO-B inhibitors

When selegiline is taken together with levodopa, side effects such as dyskinesias (uncontrolled voluntary movements), hallucinations or vivid dreaming may sometimes occur or worsen.

When people have taken rasagiline on its own (without levodopa), the most commonly reported side effects have been:

  • headache
  • aching joints
  • indigestion
  • flu-like symptoms
  • depression

When taken with levodopa, the most common reports were of uncontrolled movements and accidental falls.

Many of these side effects may be due to the increase in dopamine caused by rasagiline or selegiline. Your doctor or consultant can alter the dosage to correct these effects.

Rasagiline should not be taken together with, or within 5 weeks of receiving, Fluoxetine (Prozac) or Fluvoxamine (Faverin).
