1. An apparatus, comprising: a dispensing mechanism of a delivery device being rotatable in a first direction, the delivery device configured to dispense a drug-containing tablet to an oral mucosal membrane of a patient, the dispensing mechanism being configured to move a push rod within a delivery
1. An apparatus, comprising: a dispensing mechanism of a delivery device being rotatable in a first direction, the delivery device configured to dispense a drug-containing tablet to an oral mucosal membrane of a patient, the dispensing mechanism being configured to move a push rod within a delivery passage of the delivery device when the dispensing mechanism is rotated in the first direction to dispense the drug-containing tablet from the delivery device; anda processor operatively coupled to the dispensing mechanism, the processor configured to control the dispensing mechanism to inhibit delivery of the drug-containing tablet during a predetermined lockout period. 2. The apparatus of claim 1, wherein the lockout period includes at least one of a fixed time interval, a predetermined time interval, a predetermined variable time interval, a time interval determined by an algorithm or a variable time interval communicated to the device from a remote computer, docking station or other device. 3. The apparatus of claim 1, wherein the lockout period has a duration within the range of about 1 minute to about 60 minutes. 4. The apparatus of claim 1, wherein the lockout period is programmable. 5. The apparatus of claim 1, wherein the delivery device emits a first light when the delivery device is in the lockout period, the delivery device emits a second light when the delivery device is not in the lockout period and is ready to dispense the drug-containing tablet. 6. The apparatus of claim 1, wherein the drug-containing tablet is a first drug-containing tablet, the lockout period configured to end upon expiration of a predetermined duration of time after a second drug-containing tablet was dispensed from the delivery device. 7. The apparatus of claim 1, wherein the delivery device is associated with a patient, a duration of the lockout period is determined based at least in part on at least one of a dosing history of the patient, one or more dosing requests received from the patient by the delivery device, or a pharmacokinetic property of the drug-containing tablet. 8. The apparatus of claim 1, wherein the dispensing mechanism includes a hub coupled to a first end portion of the push rod, rotation of the hub in the first direction acting to move a second end portion of the push rod from a first position with respect to the delivery passage to a second position with respect to the delivery passage. 9. The apparatus of claim 1, wherein: the dispensing mechanism includes a hub and a motor configured to rotate the hub, andthe processor is configured to send a signal to the motor to rotate the hub when (1) a dispensing request is received by the processor, and (2) the lockout period has expired. 10. The apparatus of claim 1, wherein the delivery device emits at least one of an audible or tactile indication associated with dispensing the tablet from the delivery device. 11. The apparatus of claim 1, wherein the tablet includes a dosage of sufentanil. 12. An apparatus, comprising: a housing of a delivery device including a dispensing end configured to facilitate delivery of a first drug-containing tablet into the mouth of a patient, the dispensing end defining a delivery pathway through which the first drug-containing tablet may be passed for dispensing of the first drug-containing tablet;a push rod, at least a portion of the push rod being movably disposed within the delivery pathway of the dispensing end of the delivery device;a rotary actuator coupled to the push rod, the rotary actuator configured to move a first end portion of the push rod within the delivery pathway to dispense the first drug-containing tablet from the delivery device; anda lockout mechanism configured to control the rotary actuator to prevent dispensing of a second drug-containing tablet during a lockout period after the first drug dosage tablet is dispensed. 13. The apparatus of claim 12, wherein the lockout mechanism includes a processor configured to send a signal to actuate the rotary actuator for dispensing the second drug-containing tablet from the delivery device, the processor configured to not send the signal during the lockout period. 14. The apparatus of claim 12, wherein the rotary actuator includes a hub configured to be driven by a motor. 15. The apparatus of claim 12, wherein the lockout period includes at least one of a fixed time interval, a predetermined time interval, a predetermined variable time interval, a time interval determined by an algorithm or a variable time interval communicated to the device from a remote computer, docking station or other device. 16. The apparatus of claim 12, wherein the lockout period has a duration within the range of about 1 minute to about 60 minutes. 17. The apparatus of claim 12, wherein the lockout period is programmable. 18. The apparatus of claim 12, wherein the delivery device emits a first light when the delivery device is in the lockout period, the delivery device emits a second light when the delivery device is not in the lockout period and is ready to dispense the drug-containing tablet. 19. The apparatus of claim 12, wherein the delivery device emits at least one of an audible or tactile indication associated with dispensing the tablet from the delivery device. 20. The apparatus of claim 12, wherein the delivery device is associated with a patient, a duration of the lockout period is determined based at least in part on at least one of a dosing history of the patient, one or more dosing requests received from the patient by the delivery device, or a pharmacokinetic property of the drug-containing tablet. 21. The apparatus of claim 12, wherein: the rotary actuator is coupled to a second end portion of the push rod, andin response to a signal sent by the lockout mechanism, the rotary actuator rotates the second end portion of the push rod to move a first end portion of the push rod from a first position within the delivery pathway to a second position within the delivery pathway. 22. A method, comprising: determining at a processor of a delivery device whether the delivery device is in a lockout period, the processor configured to send a signal when the delivery device is not in the lockout period to actuate a rotary actuator of the delivery device for dispensing a drug-containing tablet from the delivery device, the rotary actuator configured upon actuation to move a first end portion of a flexible push rod within a delivery passage of the delivery device, the first end portion of the push rod configured to deliver the drug-containing tablet from the delivery passage of the delivery device; andafter the determining, (1) when the delivery device is determined to not be in the lockout period, sending the signal, or (2) when the delivery device is determined to be in the lockout period, inhibiting dispensing of the drug-containing tablet from the delivery device by not sending the signal. 23. The method of claim 22, further comprising: receiving at the processor of the delivery device a request to dispense the drug-containing tablet, the determining being performed in response to the receiving the request to dispense the drug-containing tablet. 24. The method of claim 22, wherein the lockout period includes at least one of a fixed time interval, a predetermined time interval, a predetermined variable time interval, a time interval determined by an algorithm or a variable time interval communicated to the device from a remote computer, docking station or other device. 25. The method of claim 22, wherein the tablet includes a dosage of sufentanil. 26. The method of claim 22, further comprising: rotating the rotary actuator in a first direction, the rotating acting to move the first end portion of the push rod within a nonlinear portion of the delivery passage of the delivery device. 27. The method of claim 22, further comprising: emitting via the delivery device at least one of an audible or tactile indication associated with dispensing the tablet from the delivery device.
