Which drug is NOT known to cause depression?

Glucagon is a pancreatic hormone primarily involved in the regulation of glucose metabolism by promoting glycogen breakdown and the release of glucose into the bloodstream. Unlike certain other medications, glucagon does not directly influence mood or mental health, which means it is not typically associated with causing depression.

On the other hand, beta-blockers, calcium channel blockers, and corticosteroids are known to have potential side effects that can impact mood and contribute to depressive symptoms. Beta-blockers can potentially lead to fatigue or mood changes, calcium channel blockers may have some central nervous system effects depending on the specific drug and patient's response, and corticosteroids can cause mood swings, irritability, and depressive symptoms due to their effects on the body’s hormonal balance and stress response.
