Nonmedical

Intrauterine devices are medical products that prevent conception when placed in the utems. In spite of their ancient origins, modem intrauterine devices (lUDs) have been widely used only in the last 30 years. The two generic subclasses of lUDs are nonmedicated (inert) devices and medicated lUDs, ie, progestin-releasing and copper lUDs. 

Another matrix diffusional implant consists of an outer layer of micronized, crystalline 17P-estradiol dispersed in siUcone mbber over a nonmedicated, cylindrical siUcone mbber core. The system, implanted subcutaneously in the ears of cattie, releases estradiol for up to 400 days with kinetics to improve growth rate and feed efficiency (83). 

Nonmedical uses claimed for pyridopyrimidines include uses as growth promoters, cytokinins, herbicides, agricultural fungicides, coccidiostats, dyestuffs intermediates, UV absorbants and corrosion inhibitors. 

Nonmedical uses claimed for pyridopyridazines include fungicides, growth promotion agents, parasiticides, UV absorbants and dyestuff intermediates. 

Nonmedical uses envisaged include as growth promoters, indicators for copying processes, analytical complexing agents, cyanine dyes and dye-bleaching catalysts. 

Benzodiazepines and other anxiolytics. Although benzodiazepines are widely used in the treatment of acute alcohol withdrawal, most nonmedical personnel involved in the treatment of alcoholism are opposed to the use of medications that can induce any variety of dependence to treat the anxiety, depression, and sleep disturbances that can persist for months following withdrawal. Researchers have debated the pros and cons of the use of benzodiazepines for the management of anxiety or insomnia in alcoholic patients and other substance abuse patients during the postwithdrawal period (Ciraulo and Nace 2000 Posternak and Mueller 2001).

The earlier work of Miller (35), Outright (37), and Brady (5) on nonmedicated implants provided an excellent basis for further studies on specific controlled release formulations such as the determination of the biodegradation rates of lactide/glycolide drug-loaded microspheres (38). Those studies were done with l c-iabeled polymers produced from DL-lactic acid and glycolide. The final formulations tested in rats were microspheres loaded with H-labeled steroid and polymer as the matrix. The microspheres were administered intramuscularly and animals were serially sacrificed over a period of about a year. 

While this book is focused on drug delivery, the value of biodegradable polymers is not limited to this field. Biodegradable polymers will be useful in other areas of medical therapeutics, such as sutures and bone plates and other types of prostheses. The polymers will also be useful in nonmedical fields, for disposable plastics, bottles, diapers and many other entities.

In view of this neurotoxicity, we will review some data relevant to this process. First, we will review data showing that methamphetamine (METH), a prototypic psychomotor stimulant, which has been widely used for nonmedical purposes at doses often a good deal higher than therapeutie doses, is neurotoxic to dopamine (DA) and serotonin (5-hydroxytryptamine (5-HI)) systems. Second, we will examine the evidence that other substituted phenethylamines are also neurotoxic to certain transmitter systems. Last, we will examine the behavioral and pharmacological consequences of neurotoxicity that result from exposure to some of these amphetamine-related drugs. 

Kuo P o refers to the cultivation of the plant, indicating early domestication. Tea was first described as an article of trade in the fifth century and soon thereafter as a nonmedical beverage. 

Secobarbital exhibits the same pharmacologic properties as other members of the barbiturate class. Most nonmedical use is with short-acting barbiturates, such as secobarbital. Although there may be considerable tolerance to the sedative and intoxicating effects of the drug, the lethal dose is not much greater in addicted than in normal persons. Tolerance does not develop to the respiratory effect. The combination of alcohol and barbiturates may lead to fatalities because of their combined respiratory depressive effects. Similar outcomes may occur with the benzodiazepines. Severe withdrawal symptoms in epileptic patients may include grand mal seizures and delirium.

Direct costs include both medical and nonmedical expenditures for the detection, treatment, and prevention of disease. Direct medical costs reflect resources consumed in the "production" of health care, such as pharmaceutical products and services, physician visits, and hospital care. Direct nonmedical costs reflect expenditures for products and services that are not directly related to disease treatment but are still related to patient care. Examples of direct nonmedical costs include transportation to a pharmacy or physician s office and housekeeping during the illness period. Indirect costs account for changes in productivity of an individual because of illness. The monetary value of lost or altered productivity is typically used as a measure of indirect costs. Intangible costs and consequences are nonmonetary in nature and reflect the impact of disease and its treatment on the individual s social and emotional functioning and quality of life. Table 12.2 provides examples of these types of costs and consequences.

The darker side to this issue concerns malpractice. Malpractice claims against nonmedical practitioners of alternative medicine are generally low (Studdert et ai. 1998). Although referring a patient to another physician does not generally expose a physician to liability for malpractice, there are exceptions when the referral is negligent or when there is joint treatment. Therefore, referrals to alternative medicine can potentially carry risk. 

An estimated 6.2 million persons, or 2.6 percent of the population aged 12 or older, were current users of psychotherapeutic drugs taken nonmedically. An estimated 4.4 million used pain relievers, 1.8 million used tranquilizers, 1.2 million used stimulants, and 0.4 million used sedatives. 

In the United States today, the legal standard by which "good and "bad" drugs are now measured is the Controlled Substances Act of 1970. This act divides all known drugs into one of five classes, known as schedules. The primary criterion by which a compound is placed into one or another schedule is its potential for abuse, that is, its potential for addictive or otherwise harmful nonmedical applications. The Controlled Substances Act provides detailed descriptions of, restrictions on, and penalties for the use of chemical compounds in each of the five schedules. These schedules are defined as follows ... 

Any discussion of the chemistry of drugs must include some consideration of the nonmedical applications of such compounds. Just as early humans were searching their environment for natural products that would assuage pain and cure disease, so were they also looking for plants and other natural materials with psychoactive effects, materials that would provide an escape from the problems and worries of everyday life, or that would just make a person feel better for a period of time. They also incorporated psychoactive drugs into many of their religious ceremonies. The use of the peyote cactus, magic mushrooms, and similar products dates back centuries, if not millennia, in a variety of cultures. One hardly need point out that the use of psychoactive chemicals for recreational purposes continues in essentially every part of the world today. 

The issue with nonmedical use of drugs today, however, is not only the usual risk involved with the use of any psychoactive drugs but also the increased danger posed by a host of new psychoactive products. Some of these have been developed for legitimate therapeutic purposes, hut many of them are spin-offs with unknown effects and, in some cases, known and harmful effects. As pharmaceutical... 

In a speech before the Congress in 1978, former Commissioner Donald Kennedy stated "the evidence indicates that enteric microorganisms in animals and man, their R-plasmids, and human pathogens form a linked ecosystem of their own in which action at any one point can affect every other." If the vulnerability of microorganisms to antibiotics is reduced by the use of antibiotics for nonmedical purposes in animals, the effectiveness of medical treatment will be diminished in man. Potential risks to animal health also exist, and while the linkage to human health is indirect, animal agriculture faces the risk directly. The...
