Drug regulation self-medication

Several studies have evaluated dietary supplements such as isoflavones, which are found in soy products and red clover. A well-controlled trial in more than 400 postmenopausal women evaluating a specific isoflavone, ipriflavone, found no benefits on bone mineral density or fracture rates after 3 years.47 Nevertheless, because these therapies are available without prescription and are not regulated by the FDA, patients may choose to self-medicate with isoflavones. Lymphocytopenia appeared in several patients treated with ipriflavone in clinical trials. Additionally, ipriflavone should be used with caution in immunocompromised patients or those with renal disease. It may inhibit CYP1A2 and CYP2C9 and may interact with drugs metabolized by those pathways, such as warfarin. 

Neither the FDC Act nor FDA s implementing regulations define the term switch, which typically refers to moving a drug product from Rx to OTC status. FDA will allow a switch when the prescription requirements are no longer necessary to protect the public health and the drug is safe and effective for use in self-medication as directed in the proposed OTC product labeling [89]. 

Because of the problems that resulted from self-regulation, another law, the Dietary Supplement and Non-Prescription Drug Consumer Protection Act, was approved in 2006. This law requires manufacturers, packers, or distributors of supplements to submit reports of serious adverse events to the FDA. Serious adverse events are defined as death, a life-threatening event, hospitalization, a persistent or significant disability or incapacity, congenital anomaly or birth defect, or an adverse event that requires medical or surgical intervention to prevent such outcomes based on reasonable medical judgment. If this requirement were enforced, and consumers cooperated, these reports would make it possible to identify trends in adverse effects and would help to alert the public to safety issues. 

Various approaches to self-regulation have heen taken hy different physicians organizations. However, a review of these approaches reveals general themes. In most cases, the primary justification for having a direct relationship between the pharmaceutical industry and individual physicians seems to he based on the premise that an advancement of patient healthcare will occur through increased education and research. This assumes that the information provided to the physician is impartial and also disregards the capacity of physicians to keep themselves up to date about advances in drug therapy by way of medical and other academic journals. 

Internet Member companies shall fully realise that brochures, advertisements in medical journals, internet web pages for the medical profession, and audiovisual materials such as slides, video and other promotional materials are important media in the dissemination of drug information. These items should be produced in compliance with the Pharmaceutical Affairs Law and relevant self-regulations. The statements contained therein shall be correct, fair and objective, based on scientific data. 

This section describes the types of batteries and their performance capabilities for critical medical diagnostic applications. Three distinct diagnostic systems will be described (1) microgastrointestinal systems, (2) implantable gastric stimulation system, and (3) a self-regulating response to a therapeutic drug delivery system. 

The human body is a remarkably complex biochemical process, and it shares many attributes with more traditional process control problems that have been discussed in earlier chapters. In the event that a body fails to achieve the robust level of self-regulation that occurs naturally (cf. Chapter 24), there are opportunities for medical intervention, often involving the administration of a therapeutic agent (or drug) in a prescribed manner. The therapy can be optimized using open-loop methods, but it is often advantageous to automate the process, thus removing the human from the feedback loop (much as a chemical plant removes the operator from the loop in the transition from manual control to...
