CROSS REFERENCE TO RELATED Some precursor modules of the present system contain tWo or APPLICATIONS more components of a ?nal drug product in a ?xed mixture selected to maximiZe desired pharmaceutical characteristics [0001] This application claims bene?t of priority under and minimize cost. The modules are divided into tWo classes: PCT Chapter I, Article 8, and 35 U.S.C. § 119(e) of US. 1) modules containing an active pharmaceutical ingredient or Provisional Application No. 60/874,554, entitled “Method of speci?c nutritional ingredient (hereafter called API), and 2) Making Pharmaceutical Components for Assembly of Cus modules containing only excipients. tomiZed Drug Products,” ?led on Dec. 13, 2006, Which is incorporated herein by reference. [0008] The modules can be extensively tested for quality and assembled in multiple predetermined combinations, cus tomiZing the ?nal drug product characteristics to meet TECHNICAL FIELD patient/consumer needs and/or preferences While assuring [0002] This invention relates to methods and systems for high quality. Permitted combinations can be maintained in an developing and manufacturing componentiZed drug product Internet-linkable computer database to enable netWorked precursor modules that can be assembled to create custom drug product selection, prescribing, and ordering. The result iZed drug products. ing customiZed drug product can facilitate compliance and reduce the number of drug products administered per day. BACKGROUND ART [0009] Some embodiments of the present invention provide an API module, comprising: at least one excipient in a ?rst [0003] Pharmaceutical products for use in humans or ani ?xed amount, and at least one active pharmaceutical ingredi mals are produced primarily in tWo Ways. High volume or ent in a second ?xed amount of at least a dose escalation high priced drugs are manufactured under very tightly con interval or a fraction thereof. In other embodiments, the sec trolled conditions With detailed speci?cations, quality test ond ?xed amount can be greater than the dose escalation ing, and documentation. Because of the high cost and com interval. In still other embodiments, the second ?xed amount plexity of this type of pharmaceutical manufacturing, loW can be less than a dose of the at least one active pharmaceu volume, highly specialiZed drugs are produced in a cottage tical ingredient. Additional embodiments provide the second industry of compounding pharmacies. These pharmacies mix ?xed amount being less than the minimum dose of the at least various active ingredients and excipients into an often unique one active pharmaceutical ingredient. In yet other embodi product based on a doctor’s prescription. The speci?cations, ments, methods for making at least one API module are quality testing, and documentation are often minimal or non provided. Such methods comprise, in some embodiments,
