Paroxetine brand name princeps?

What was the original (brand-name) princeps for paroxetine?

Paroxetine’s original brand (its princeps) was Paxil (paroxetine hydrochloride).

How does “princeps” relate to generic paroxetine and other brand names?

“Princeps” refers to the first marketed branded version of a drug active ingredient. After patent/market exclusivity periods, generic paroxetine entered the market under the generic name “paroxetine” in many countries, while older branded versions such as Paxil may still be sold depending on the country.

What if you meant the princeps in a specific country?

Brand history can differ by country (for example, different launch timelines or naming conventions). If you tell me the country/market (e.g., US, UK, India, EU), I can narrow the princeps name to that jurisdiction.
