Abstract: A medical practitioner creates a prescription using a handheld portable device. The device uses a plurality of interactive screens that display information such as lists of drugs. The medical practitioner enters patient information and selects from the list the desired drug to be prescribed. The device gives the practitioner access to a drug database that may be limited by the drugs prescribable by the medical practitioner. Once a prescription is created, the practitioner can select a drug dispensing location and communicate the prescription to this location. The drug database and the drug dispensing locations may be stored in a removable memory.
