Here are combination-name ideas for paracetamol + diclofenac:

More professional, generic-style options:

Before using any as a real brand, check trademark availability and local medicine-naming regulations. This combination should also be formulated and prescribed cautiously: diclofenac can cause gastrointestinal, kidney, cardiovascular, and liver-related adverse effects, and acetaminophen/paracetamol adds liver-toxicity risk, especially if other paracetamol-containing products are taken. FDA labeling advises caution when diclofenac is used with potentially hepatotoxic medicines such as acetaminophen, as reflected in the diclofenac safety label.

Easy-to-pronounce, stylish name ideas for a Paracetamol + Diclofenac combination:

My strongest short, brand-style picks:

Use a trademark and regulatory name-screening process before choosing one, since many short medicine-like names may already be registered or may be too similar to existing products.

Premium, modern name ideas:

Best fits for a modern pain-relief product:

For a more pharmaceutical feel, use a suffix such as -D, Plus, Max, or Forte only if permitted locally, for example: Velora-D, Aurevia Plus, Nuvora Forte.

Avoid finalizing a name until trademark, regulatory, and look-alike/sound-alike medicine-name screening are completed.
