Almotriptan is a new highly potent selective 5-HT1B/1D receptor agonist developed for the treatment of migraine, and the disposition of almotriptan in different animal species is now addressed in the current study. Almotriptan was well absorbed in rats (69.1%) and dogs (100%) following oral treatment.

This open, randomized, crossover, single-dose clinical trial evaluated the possible pharmacokinetic interaction between a single oral dose of almotriptan 25 mg, a 5-HT1B/1D receptor agonist for the acute treatment of migraine, and food intake in healthy volunteers. The influence of food intake in the rate and extent of almotriptan absorption was evaluated by bioequivalence criteria. Tolerability and safety of treatment were also assessed.

Almotriptan is a novel highly selective 5-hydroxytryptamine(1B/1D) agonist developed for the acute oral treatment of migraine. The in vitro metabolism of almotriptan has been investigated using human liver subcellular fractions and cDNA-expressed human enzymes, to study the metabolic pathways and identify the enzymes responsible for the formation of the major metabolites. Specific enzymes were identified by correlation analysis, chemical inhibition studies, and incubation with various cDNA expressed human enzymes.

Absolute bioavailability, pharmacokinetics, and urinary excretion of almotriptan, a novel 5-HT(1B/1D) receptor agonist, were studied in 18 healthy males following single intravenous (i.v.) (3 mg), subcutaneous (s.

Pancopride (LAS 30451, CAS 121650-80-4) is a new selective 5-hydroxytryptamine3 receptor antagonist which has demonstrated antiemetic properties in animal models. The tolerance and pharmacokinetics of pancopride and its effect on the 5-hydroxytryptamine flare test were examined in healthy male volunteers, in three single-dose studies. The studies consisted of two rising dose tolerance and kinetic studies with placebo control, each involving 14 volunteers, and an absolute bioavailability study involving 12 volunteers.

The aim of this study was to assess the pharmacokinetic profile of pancopride after repeated oral dose administration of 20 mg pancopride in tablet form once a day for 5 d in 12 healthy male volunteers. Plasma levels were measured by HPLC using a solid phase extraction method and automated injection. The minimum quantification limit of pancopride in plasma was 2 ng mL-1.

The pharmacokinetics and pharmacodynamics of ebastine at single oral doses of 10 and 20 mg were studied in six healthy beagle dogs. Plasma concentrations of the active metabolite of ebastine were measured at predetermined times after the dose. At these times an intradermal injection of 0.

We studied the influence of administration route on the biopharmaceutical behavior of etodolac. The levels obtained in plasma when the same dose of etodolac is administered orally (tablets, dosage form A) and rectally (suppositories, dosage form B) were compared. The study was done in a crossover design with healthy volunteers of both sexes, of average build, and younger than 35 years of age.

The present study describes the pharmacokinetic behaviour of a new dosage form of etodolac not available in the Spanish market: suppositories. Rectal administration was chosen as an alternative for the oral route. The dose used was 200 mg.

Almagate (hydrated aluminium-magnesium hydroxycarbonate, Al2Mg6(OH)14(CO3)2 X 4 H2O, Almax) in the form of tablets and suspension was compared with other commercially available antacid preparations in a battery of tests designed to evaluate antacid activity and related properties. The evaluation of an antacid should take into account, in addition to total acid neutralising capacity, neutralising capacity under dynamic conditions related to in vivo events, bioavailability, speed of action, lack of possible rebound effect and low sodium content. When these considerations are taken into account Almax tablets and suspension can be classified as highly effective antacids retaining a high proportion of their total neutralising capacity under simulated in vivo conditions.
