Described here are methods, devices, and kits for microjet drug delivery. The devices described here may be modular or non-modular. The modular devices typically include a first module (102) having a drug reservoir (103) and a nozzle (302) in fluid communication with the drug reservoir and a second module (104) having an actuator and a power supply. The power supply provides power to the actuator and when the first and second modules are coupled, the actuator is capable of acting on a dispensing member (318) causing it to dispense a drug in liquid form from the drug reservoir via the nozzle at a velocity sufficient to penetrate skin. Other devices described include a nozzle, a reservoir in fluid communication with the nozzle, a dispensing member, and an actuator. In these devices, the nozzle has at least one feature that enhances nozzle contact with the skin in order to reduce lateral drug leakage about the nozzle. |
