MAO-B Inhibitors
Monoamine Oxidase Type B (MAO-B) is an enzyme in our body that breaks down brain chemicals such as dopamine. MAO-B inhibitors block the effect of MAO-B to improve many motor symptoms of PD. MAO-B inhibitors are commonly used in early therapy or in addition to other medications to help reduce "off" time and extend "on time." Some studies indicate that MAO-B inhibitors slow the progress of PD by offering neuroprotection. MAO-B inhibitors are used to treat:
​
-
Slowness
-
Stiffness
-
Tremor
-
"On/Off" fluctuations
​
The most common side effects of MAO-B inhibitors include:
​
-
Mild nausea
-
Dry mouth
-
Lightheadedness
-
Constipation
​
Pharmacists routinely warn about other drug interactions with MAO-B inhibitors, including antidepressants. Prior to starting any MAO-B inhibitor, carefully review all medications, including over the counter medications with your physician for possible adverse reactions. It is also very important to provide information about MAO-B inhibitors to anesthesiologists prior to any surgeries.
