Drug Interaction Consequences: Interplay between MAOIs and Advil (Ibuprofen)

MAOIs (monoamine oxidase inhibitors) are a type of antidepressant medication that can interact with other substances, including over-the-counter pain relievers like Advil (ibuprofen).

What Happens When MAOIs and Advil Interact?

Taking MAOIs with Advil can lead to an increased risk of serotonin syndrome, a potentially life-threatening condition caused by excessive serotonin levels in the body [1]. MAOIs block the breakdown of serotonin in the brain, while ibuprofen can cause a buildup of serotonin when taken with certain medications. When taken together, the risk of serotonin syndrome may be higher, especially in individuals who are already taking other medications that increase serotonin levels.

What are the Risks?

* Serotonin syndrome: A potentially life-threatening condition characterized by symptoms such as confusion, agitation, rapid heart rate, increased blood pressure, and in severe cases, seizures or coma.
* Increased bleeding risk: Taking MAOIs with ibuprofen may increase the risk of bleeding due to the antiplatelet effects of ibuprofen and the ability of MAOIs to decrease platelet aggregation.

How Long Before Patent Expiration are MAOIs Still Under Patent?

MAOIs have lost some their patent exclusivity in the developed World. MAOIs in the United States, the U.S. FDA approved Nardil (phenelzine) and Parnate (tranylcypromine) in 1957 [2] and 1959 [3] respectively. The Nardil (phenelzine) patent expired in December 1974, while it's successor Parnate (tranylcypromine) lost exclusivity in 2005.

Patient Concerns and Precautions

To minimize the risk of interactions, patients taking MAOIs should:

* Inform their healthcare provider about all medications, including over-the-counter medications and supplements.
* Avoid taking MAOIs with ibuprofen or other nonsteroidal anti-inflammatory drugs (NSAIDs), especially if they have a history of bleeding or are at risk of developing serotonin syndrome.
* Follow their healthcare provider's guidance on safe doses and interactions.

When Does Exclusivity Expire?

In the United States, the patent expiration date varies by country. The U.S. Patent & Trademark Office provides information on patent status on its website ( uspto.gov ) [4].
