Abstract: A drug database system that is particularly adapted for drug prescribing and drug dispensing activities is disclosed. In accordance with one aspect of the present invention, information on the usage, dosing and contraindications for a plurality of drugs is provided via a communications link to persons desiring such information. All information is provided in response to a request that includes specific information. The information provided can be of different types and varies with the information in the request. The information provided may be provided to the person making the request or to another person associated with the person making the request. Advantageously, the system provides real-time access to a plurality of persons requesting drug information. In addition, the drug information stored in the system may be dynamically modified. Such modifications is provided by permitting selective access to the database by drug manufacturers, drug researchers and the like.

Abstract: A pharmacy drug management system provides pharmacy drug management software for patient-specific drug dosing, drug interaction analysis, order generation, and patient data matching. When a drug is added for a patient, the system detects if the drug is a doser drug requiring precise therapeutic dosing and also detects if the drug will cause any drug interaction problems for the patient, reducing the likelihood of clinical misjudgments. The system checks for drug interaction problems resulting from drugs, food allergies, and the medical condition of the patient. An on-screen order may then be generated. A doctor or pharmacist thus is aware of any drug interaction problems before writing an order for the patient. If a selected drug is a doser drug, the system uses phannacokinetic equations specific to the patient data to calculate the appropriate therapeutic dosing parameters.
