Bupropion is an antidepressant that is used to treat depression and aid in quitting smoking. It is frequently marketed under brand names like Zyban and Wellbutrin. Dopamine and norepinephrine are the two main neurotransmitters that bupropion primarily affects, in contrast to the majority of popular antidepressants that target serotonin.
Bupropion’s Mode of Action: How It Operates
Bupropion is a member of the norepinephrine-dopamine reuptake inhibitor (NDRI) drug class. It functions by preventing dopamine and norepinephrine from being reabsorbed into the brain. Two neurotransmitters that are important for mood, motivation, pleasure, and attention regulation are norepinephrine and dopamine. The benefits of these substances are diminished when neurons reabsorb them too quickly, which may be a factor in depressive, lazy, or motivational states. Because bupropion blocks this reuptake, the brain retains more of these neurotransmitters, which can elevate mood and increase vitality.
Bupropion differs from serotonin-norepinephrine reuptake inhibitors (SNRIs) and selective serotonin reuptake inhibitors (SSRIs) due to this mechanism. Bupropion addresses separate elements of brain chemistry by modulating dopamine and norepinephrine, which frequently results in differing therapeutic effects.
