Dose Escalation phase:

Each study treatment consisted of an intravenous infusion of Org 25435, given by Infusion pump over exactly 1 minute.

Target Controlled Infusion phase:

Each study treatment consisted of an intravenous infusion of Org25435 given by a computer-controlled infusion over 30 minutes.

Criteria for Evaluation Tolerability, adverse events, EEG effects, cardiovascular effects, electrocardiogram (ECG), excitatory phenomena, respiratory effects, laboratory safety blood analyses, pharmacodynamic and pharmacokinetic measurements. Efficacy Induction phenomena; time of cessation of speech, eye closure, loss of eyelash reflex, eyes open on command, limb movement on command and syringe drop. Other Induction phenomena; pain on injection, sign of histamine release, excitatory phenomena, respiratory depression, apnea. Recovery phenomena; nausea / vomiting, delirium, shivering, disturbed psychomotor function, eye opening on command, spontaneous respiration, adequate respiration, move limbs on command, increased saliva production.

Statistical Methods Formal statistical methods are not appropriate in this small pilot investigative study where group sizes comprise 5 or less subjects. All data collected is presented and summarized according to investigation type (Dose Escalation or TCI).
