Methylphenobarbital
Methylphenobarbital (INN), also known as mephobarbital (USAN, JAN) and mephobarbitone (BAN), marketed under brand names such as Mebaral, Mephyltaletten, Phemiton, and Prominal, is a drug which is a barbiturate derivative and is used primarily as an anticonvulsant, but also as a sedative and anxiolytic. It is the N-methylated analogue of phenobarbital and has similar indications, therapeutic value, and tolerability.
Approval history
1935 – Mebaral was introduced by Winthrop Pharmaceuticals.
2001 – Methylphenobarbital discontinued in the UK.
2003 – Mebaral was acquired by Ovation Pharmaceuticals (a specialty pharmaceutical company that acquired under-promoted branded pharmaceutical products).
2009 – Ovation was acquired by Lundbeck, which now markets Mebaral.
2012 – Lundbeck announced that they were abandoning the product in the US as of January 6, 2012. The stated reason was because "the company thoroughly evaluated all avenues for keeping MEBARAL TABLETS available to patients, but ultimately concluded that no matter what steps they [i.e. Lundbeck] took, patients would be forced to transition to a new therapy."
