It starts with the development of a compound. The drug company gets a U.S. patent on the formula. This patent gives them a 20-year exclusive right to develop and test the compound and, if approved, to sell it as a patented brand-name prescription drug.

But afterwards, other companies can apply for permission to make and sell the same compound as a generic.

Seasonal Affective Disorder is called SAD for short. And, some people with this form of depression feel sad.
But for guys especially, depression—whether it’s seasonal or not—is more likely to cause feelings of irritability, anger, and hostility.
The good news is that depression is treatable. It’s just as important to treat as any other condition that keeps you from enjoying life.
