| 摘要 |
A control device and a drug delivery system containing such a control device are disclosed for delivery to a patient of a drug or a placebo (or ineffective dose of the drug) according to a partial reinforcement schedule, whereby the placebo (or ineffective dose of the drug) is delivered in whole or in part during one or more delivery events. Methods of modulating the drug/placebo delivery to a patient are also provided, whereby the delivery event is initiated either according to a patient-initiated signaling event (i.e., a self-medication mode) or an automated signaling event (i.e., automated mode).
