The clinical histories of three families are described, who have a variant of familial periodic paralysis characterized by high concentration of potassium during paralytic episodes unassociated with diminished urinary excretion of potassium. Data are presented concerning five hospitalized patients from the three families. The data indicate that the rise in concentration of potassium in serum results from a shift of potassium into the extracellular phase. During the recovery period potassium travels in the opposite direction. The administration of glucagon or epinephrine during an acute attack terminated the attack promptly. The administration of 10 to 15 mg of dextro-amphetamine sulfate daily in Spansule® form effectively controlled symptoms in two patients, and resulted in definite improvement in a third patient, treated for periods varying from 3 to 7 months.

Abstract Eight laboratories collaboratively studied a method for the quantitative GLC determination of d- and l-amphetamine in tablets. The drugs are separated from tablet excipients by column chromatography and reacted with Ntrifluoroacetyl-( 0-prolyl chloride, and the resulting derivatives are analyzed by GLC. The samples consisted of commercial d-amphetamine sulfate tablets (with and without butabarbital), dl-amphetamine sulfate tablets, and a mixed d- and l-amphetamine sulfate standard. Recoveries were acceptable, and the standard deviations never exceeded 0.64%. The results demonstrate that the method gives good precision and accuracy, and the method is recommended for adoption as official first action.

A system for the infusion of drug solutions into the blood stream of relatively unrestrained and unanesthetized squirrel monkeys, via a chronic intravenous catheter, is described. Results pertaining to the maintenance of schedule-controlled behavior by response-contingent infusions of d-amphetamine sulfate are included to illustrate a specific application of the technique.

AbstractStudy ObjectivesWe compared the bioavailability of racemic amphetamine (d-amphetamine and l-amphetamine) from a manipulation-resistant immediate-release (IR) amphetamine sulfate capsule (AR19) versus amphetamine sulfate IR tablets (reference).MethodIn this open-label, randomized, two-period, two-treatment, two-sequence, crossover study, 36 healthy volunteers aged 18–45 received a single dose (20-mg capsule) of AR19 in one period and a single dose (2 x 10-mg tablets) of reference in another period, after a 10-hour overnight fast. Each drug administration was separated by a washout period of at least 6days. Bioequivalence for d- and l-amphetamine was assessed using time to peak concentration (Tmax), peak concentration in plasma (Cmax), and area under the plasma concentration–time curve from time-zero to the time of the last quantifiable concentration (AUClast) and extrapolated to infinity (AUCinf).ResultsAll 36 volunteers completed both treatment sequences. Mean (standard deviation; SD) Tmax for d- and l-amphetamine was similar for AR19 (2.84[1.05]; 3.05[1.22], respectively) and reference (2.52[0.75]; 2.75[1.00], respectively). The geometric least-squares mean ratios and 90% confidence intervals were within the boundary of 80%–125% for bioequivalence for Cmax (d-amphetamine, 98.35% [96.12–100.64]; l-amphetamine, 98.82% [96.42–101.28]), AUClast (d-amphetamine, 99.45% [96.92–102.05]; l-amphetamine, 99.29% [96.55–102.10]), and AUCinf (d-amphetamine, 99.50%[96.77–102.30]; l-amphetamine, 99.23% [96.06–102.50]). A total of 13 mild adverse events were reported by 7 volunteers (AEs; AR19, n=5; reference, n=8). No serious AEs were reported.ConclusionAR19 was well tolerated and was bioequivalent to reference when administered as a 20-mg dose in healthy volunteers.Funding Acknowledgements: This study was funded by Arbor Pharmaceuticals, LLC.
