Dopamine system dysfunction is linked to certain symptoms of depression, such as low motivation. Serotonin is involved in how you process your emotions, which can affect your overall mood.
What is antagonistic to dopamine?
Dopamine antagonists include specific receptor antagonists (e.g., antipsychotics, buspirone, metoclopramide, and amoxapine), agents that block synthesis (e.g., metyrosine), agents that prevent vesicle storage (e.g., reserpine and tetrabenazine) or cause dopamine depletion (e.g., α-methyldopa), or agents that destroy …

What is the difference between dopamine and dobutamine?
Dopamine is typically used in the treatment of septic shock or cardiogenic shock. Dobutamine is a drug that primarily stimulates beta-1 receptors, leading to increased inotropic and chronotropic effects. to al lesser extent, dobutamine also stimulates beta-2 adrenergic receptors, leading to vasodilatation.
