Armodafinil (Waklert 150) is stronger. The R-enantiomer of modafinil, armodafinil, is isolated from one of its two mirror-image molecules. This structural difference permits armodafinil to sustain greater plasma concentrations later in the day, possibly prolonging wakefulness.
In clinical settings, 150 mg armodafinil produces effects equivalent to 200 mg modafinil, confirming its milligram-to-milligram efficacy.
Adderall and other amphetamine-dextroamphetamine stimulants have stronger stimulating effects than modafinil. Amphetamine-dextroamphetamine is stronger than modafinil and should be used cautiously.
These drugs may increase wakefulness, but they have different side effects and dangers. To ensure safety and effectiveness, medication modifications should be performed by a healthcare expert.
