Key differences

Mechanism and action
Voltaren: Diclofenac reversibly inhibits cyclooxygenase enzymes COX-1 and COX-2, with somewhat greater selectivity for COX-2 than ibuprofen and naproxen. 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.
