title: Sustained-release applications of montmorillonite interaction with amphetamine sulfate.
abstract: Urinary recovery studies showed that montmorillonite significantly affects the initial therapeutic levels of amphetamine sulfate. The combination of a 1:20 drug-montmorillonite complex with pure drug in a 1:1 ratio, based on amphetamine content, resulted in recovery profiles resembling those obtained from prolonged-release dosage forms. The 1:20 complex, pure drug, and combination formulations showed comparable bioavailability after 48 hr.
