Sparlon contains the ingredient modafinil, the same ingredient found in Provigil, a sleep-disorders drug that also is Cephalon's best-selling product. Sparlon contains a higher dose of the ingredient than does Provigil.
Provigil doesn't have any black box warnings nor does it have any alerts for dangerous skin problems. No ADHD drug has such a warning for the dangerous skin rashes. Strattera, from Eli Lilly (LLY Quote), has a black box warning about suicidal thinking in adolescents. The label also alerts patients to potential liver damage. Adderall and Adderall XR, from Shire PLC (SHPGY Quote) have a black box regarding potential amphetamine abuse. Last month, another FDA advisory committee recommended that all stimulant-type ADHD drugs carry a black box warning for cardiovascular risk. The vote was 8-7, with one abstention, covering drugs such as Shire's medications, Ritalin from Novartis (NVS Quote), generic versions of Ritalin, and Concerta from Johnson & Johnson (JNJ Quote). Several smaller brands also would be affected because they are stimulants. Neither Strattera nor Cephalon is viewed as a stimulant by the FDA. Stevens-Johnson syndrome played a role in the FDA's requesting the removal from the market of Bextra, a Pfizer (PFE Quote) arthritis drug that was withdrawn last April. Bextra's label already had a black box warning for this disease when the FDA asked Pfizer to pull it, saying the drug's risks outweighed its benefits. The agency also cited a "potential increased risk" of serious cardiovascular injury in asking Pfizer to withdraw Bextra.- Loading Comments...
