Bupropion Xl 150Mg

Bupropion XL 150mg is a prescription medication that belongs to the class of drugs known as norepinephrine-dopamine reuptake inhibitors (NDRI). It is primarily used to treat major depressive disorder (MDD) and seasonal affective disorder (SAD). Bupropion XL 150mg is an extended-release formulation, which means that it releases the active ingredient, bupropion, slowly over a prolonged period, allowing for once-daily dosing.

Bupropion works by increasing the levels of certain neurotransmitters, such as norepinephrine and dopamine, in the brain. These neurotransmitters play a crucial role in regulating mood, motivation, and reward processing. By inhibiting the reuptake of norepinephrine and dopamine, bupropion increases their availability in the synaptic cleft, which can help to improve mood, reduce symptoms of depression, and increase energy levels.
