Nuvigil vs Waklert
The same brand-versus-generic story as Provigil and Modalert, one tier up. Nuvigil is the original armodafinil brand, Waklert is Sun Pharma's generic of the same molecule, for far less money.

The short answer
Nuvigil is the original brand name for armodafinil, made by Cephalon, and priced like a brand medication. Waklert is Sun Pharma's generic armodafinil, the same active ingredient at 150mg, sold for far less. The molecule is identical between them. Armodafinil itself is the longer-acting single enantiomer of modafinil, the purified half of the modafinil molecule that clears the body more slowly. As with Provigil and Modalert, the choice between Nuvigil and Waklert is a brand-versus-generic pricing question, not a difference in the drug.
What armodafinil actually is
Modafinil is a racemic compound, meaning each tablet contains two mirror-image versions of the same molecule, a fast-clearing half and a longer-lived half. Armodafinil is the longer-lived half on its own, purified out and sold as its own drug. That is the whole relationship: armodafinil is not a separate invention, it is one component of modafinil isolated and marketed separately, with a longer hold into the afternoon.
Same brand-versus-generic pattern
Nuvigil was Cephalon's brand name for armodafinil, brought to market after Provigil, following the same original development and approval path and carrying the same brand-name pricing. Waklert is Sun Pharma's generic version of armodafinil, manufactured in India at a fraction of Nuvigil's cost. This is the identical story as Provigil and Modalert, one level up the same drug family.
Same molecule, same standard
Waklert contains armodafinil at 150mg, the same active ingredient and strength that Nuvigil is sold under in various doses. Generic armodafinil is held to the same active-ingredient standard as the brand it copies. There is no pharmacological reason to expect a different effect from the same molecule made by a different manufacturer.
What actually matters when choosing
Almost nobody buying armodafinil online outside the United States is paying Nuvigil's brand price when a generic exists at a fraction of the cost. The decision that matters is not the name on the box, it is whether the specific vendor is shipping genuine armodafinil at the strength it claims. That question applies the same way it does for Provigil versus Modalert, and it is a sourcing question, not a brand question.

Common questions

What is armodafinil, exactly?
Armodafinil is the longer-acting single enantiomer of modafinil, the purified half of the modafinil molecule that clears the body more slowly. It is not a separate drug invented from scratch, it is one component of modafinil isolated on its own.
Why choose Waklert over Nuvigil?
Same active ingredient, far lower price. The real consideration when buying either is vendor authenticity, not which name is printed on the tablet.
