Is the word relaxante the same in Brazilian and European Portuguese?

Yes

The word "relaxante" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation:

• Brazilian Portuguese: The vowels are generally more open and clearly articulated. The unstressed "e" at the end of the word is typically pronounced as a clear [e] or a slightly reduced [i].
• Continental Portuguese: The vowels are more "closed" or "reduced." The unstressed vowels are often swallowed or whispered, making the word sound more consonant-heavy. The final "e" is often almost silent or pronounced as a very short, muffled sound.
