The most distinctive ingredient in modern combination formulas — acts on the brain's arousal circuitry rather than blood vessels, addressing the neurological dimension of ED.
Onset: Under 20 minutes (sublingual)Duration: Up to 8 hours
Apomorphine acts on dopamine D1 and D2 receptors in the hypothalamus and other brain areas involved in sexual arousal. By activating these receptors, it mimics and amplifies the brain's own arousal signal, lowering the threshold for sexual arousal and strengthening the neurological component of erection. Unlike PDE5 inhibitors, it addresses the desire and arousal initiation phase rather than the vascular response phase.
