What's the same
Ambien and Paxil are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Ambien belongs to Sleep Aids and Hypnotics while Paxil belongs to Anti-Depressants. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Ambien: Zolpidem is a positive allosteric modulator of the GABA-A receptor with relative selectivity for the alpha-1 subunit, which is associated with sedation and sleep induction. Paxil: Paroxetine selectively inhibits the serotonin reuptake transporter (SERT), increasing synaptic serotonin availability.
When Ambien is preferred

When Paxil is preferred
Paxil is approved for major depressive disorder, generalised anxiety disorder, social anxiety disorder, panic disorder, obsessive-compulsive disorder and post-traumatic stress disorder, with regional variation.
Frequently asked questions

Can I switch from Ambien to Paxil? ▾
