Ibuprofen, the active ingredient in Advil, shares certain chemical similarities with some antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) [1]. Both ibuprofen and SSRIs are composed of aromatic rings and carbon chains, with functional groups that allow them to interact with specific targets in the body [2].

Ibuprofen's chemical structure includes a carboxylic acid group, which is responsible for its anti-inflammatory and analgesic effects [3]. Some antidepressants, such as fluoxetine (Prozac), also have a similar carboxylic acid group in their structure [4]. This structural similarity may contribute to the observed effects of both classes of drugs on mood and emotional regulation [5].

However, it is important to note that while ibuprofen and antidepressants share some structural similarities, their mechanisms of action are distinct. Ibuprofen primarily works by inhibiting cyclooxygenase (COX) enzymes, thereby reducing the production of prostaglandins and other inflammatory mediators [6]. Antidepressants, on the other hand, primarily act by increasing the availability of neurotransmitters, such as serotonin and norepinephrine, in the synaptic cleft [7].

In summary, while ibuprofen and antidepressants share some chemical similarities, their mechanisms of action are different, and they are used for different therapeutic purposes.
