Almost inevitably, when a drug is a racemic mixture, one enantiomer will be the active species, while the other will be inactive and just going along for the ride. Thus, a mg pill of a racemic mixture Prilosec will contain only 50 mg of active drug. But a mg dose of a single enantiomer Nexium contains mg. So, a single enantiomer will deliver twice the effective dose of the racemate. Not really, but there are web sites where numerous people have written that Nexium worked better than Prilosec for them.
And, they are no doubt right. The dosing schedule for Prilosec shows why:. Although the dosage of the pills above is the same colored circles , the people who are taking Nexium are getting twice the effective dose than those who are taking Prilosec, so it makes perfect sense that they feel better.
