Methoxetamine & SSRIs
Methoxetamine (MXE), often referred to colloquially as "Mexxy" or "M-ket," is a dissociative anesthetic that was developed as a synthetic analog of ketamine. Its pharmacological profile is complex and multifaceted, impacting various neurotransmitter systems in the brain.
MXE primarily acts as an antagonist at the N-methyl-D-aspartate (NMDA) receptors in the brain. NMDA receptors are involved in the transmission of electrical signals between neurons in the brain and spinal column; they are necessary for memory and cognition. By blocking these receptors, MXE disrupts normal brain function, leading to its dissociative effects. This is similar to other dissociative anesthetics like ketamine.
MXE may also inhibit the reuptake of dopamine, a neurotransmitter associated with pleasure, reward, and motivation. This inhibition can increase dopamine levels in the brain, potentially contributing to mood elevation and euphoric effects.
Some evidence suggests that MXE may also have a mild inhibitory effect on the reuptake of serotonin, although this action is less pronounced than its effects on NMDA receptors and dopamine reuptake.
Users often experience a sense of detachment from their body and surroundings, an effect known as dissociation. This can range from mild detachment to a more profound disconnection, sometimes described as entering a different reality or "k-hole." MXE can induce hallucinations, altered perception of colors and sounds, and a feeling of altered reality. These effects are due to their impact on the brain's sensory and perceptual processing. The dopaminergic activity of MXE can lead to feelings of euphoria, elevated mood, and a subjective sense of well-being. As with other NMDA antagonists, MXE has pain-relieving properties, though these are often secondary to its psychoactive effects.
Selective Serotonin Reuptake Inhibitors (SSRIs) block the reuptake of serotonin, increasing its availability in the synaptic cleft, thus enhancing mood and emotional regulation. They are primarily used to treat depression and anxiety disorders. Common side effects include sexual dysfunction, weight gain, and emotional blunting. Excessive serotonin activity can lead to a potentially life-threatening condition known as serotonin syndrome.
SSRIs are a widely used class of medications. Here are some common examples:
- Fluoxetine (Prozac): Notable for being one of the first SSRIs on the market and having a relatively stimulating effect, which can be beneficial in patients with fatigue and lethargy.
- Sertraline (Zoloft): Known for its relatively balanced profile in terms of side effects and efficacy.
- Paroxetine (Paxil, Seroxat): It is somewhat more sedating than other SSRIs and can be useful in patients with high levels of anxiety or insomnia. However, it is also associated with weight gain and sexual side effects more often than some other SSRIs.
- Citalopram (Celexa): Known for its simplicity in dosing and having fewer drug interactions, but there are some concerns about heart rhythm disturbances at higher doses.
- Escitalopram (Lexapro): A more potent form of citalopram (it is the S-enantiomer of citalopram) and is generally well-tolerated with a relatively favorable side-effect profile.
- Fluvoxamine (Luvox): Often chosen for its effectiveness in OCD and is unique among SSRIs for not being typically used as a first-line treatment for depression.
Each SSRI has a slightly different pharmacological profile, which can influence its effectiveness, side effects, and combinations in different individuals.
MXE and SSRIs interact through complex pharmacological mechanisms, each affecting the brain in distinct ways. MXE's potential dopaminergic and NMDA antagonistic effects combined with SSRI-induced serotonergic changes might lead to heightened psychotomimetic effects: anxiety, paranoia, hallucinations, or other psychotic-like symptoms. The combination might exacerbate cognitive dysfunction and increase the risk of developing serotonin syndrome. Among the symptoms that may be observed are high body temperature, agitation, intensified reflexes, tremors, sweating, dilated pupils, diarrhea, and coma.
The combination does not carry obvious bonuses or discoveries but provides risks for bad times, mental health, and life in general.
All things considered, we recommend avoiding this combination under any conditions.
