Unused medicines

Although procedures for the recovery of the tin compound have been reported, such procedures would be prohibitively costly on a large scale and would probably leave behind sufficient tin residues such as to render the products unusable for medicinal testing. See S. Kobayashi, T. Busujima, S. Na-gayama, Chem. Commun. 1998, 981-982. 

Physicians who have drug problems sometimes use a process called harvesting in order to obtain the medications for their own personal use. Harvesting occurs when a physician (seemingly innocendy) asks a patient to return any unused pain or other type of mood-altering medications to the physician. The physician will tell a patient that this is for his or her protection to take away the threat of accidental use of the medicines by someone in the household. The physician will offer to dispose of the medicine properly so that it is out of the household. However, the medicines will likely be used by the physician instead of being wasted. Patients should understand that since they have paid for (or their insurance has paid for) those medicines, it is unethical for a physician to ask for them in the first place, and such a request should warn of a problem. 

Neither the NHS Trust nor the Site Principal Investigator shall permit the Investigational Medicinal Product to be used for any purpose other than the conduct of the Clinical Trial and upon termination or expiration of this Agreement all unused Investigational Medicinal Product shall, at the Sponsor s option, either be returned to the Sponsor or disposed of in accordance with the Protocol. 

One additional element that needs to be built into a company s plans for NICE is how to handle the uncertainty in the marketplace when an appraisal is announced and then performed by NICE. Once an appraisal of a compound has been announced and the timetable for the appraisal made public by NICE, there is a tendency for prescribers and NHS bodies to adopt a wait and see approach to the prescribing of the new medicine. If strategies are not introduced to overcome this hurdle to initiation and use of your product, then it will languish largely unused for a couple of years while the appraisal process unfolds. 

The sponsor is responsible for the destruction of unused investigational medicinal products. Investigational medicinal products should therefore not be destroyed by the manufacturer without prior written authorization by the sponsor. 

Chitin and chitosan have various characteristics that are not found in other natural polymers and biopolymers. However, for a long time, chitin and chitosan were unused bioresources. In the investigation of the importance of natural polymers, chitin and chitosan, as well as cellulose, are being considered functional polysaccharides, and are actively being studied and applied in various fields, such as medical treatment, medicine, food, chanical industries, fibers, and others (Uragami et al. 2001 Uragami and Tokura 2006). 

Amoxicilhn is an antibiotic packaged as a powder. When it is used to treat babies and small animals, the pharmacist or veterinarian must suspend it in water, so that it can be administered orally with a medicine dropper. The label says to dispose of unused suspension after 14 days. It also points out that refngeration is required. In the context of this chapter, what is implied in the latter two statements ... 

A variety of techniques reduce the risk to a patient. Grounding and double insulation help. Isolation of circuits and sensor leads, minimal current for equipment operation, low voltages, and turning off unused equipment can all help. Shielding reduces magnetically induced currents. Some patient situations can become very complex, requiting special analysis to determine a safe solution. There are safe current limits and standards for the safe use of electrical equipment in hospitals and medicine. The American Association of Medical Instmmentation publishes a range of standards applicable to medical equipment. ... 

The impact on environment may occur throughout the life cycle, from manufacturing and preparation, through distribution and dispensing, to patient excretion and final disposal of unused medicines and waste.

Under Article 127b of EU Directive 2001/83/ (Community code relating to medicinal products for human use), as amended, all EU Member States shall ensure that appropriate collection systems are in place for medicinal products that are unused or have expired . 

The community pharmacy has to take back from patients medicines that are no longer required, or expired medicines, these are the so-called unused medicines (see Sect. 38.4.2). 

Unused medicines can pose a health and social risk if they come into wrong hands, for example children or addicts and they can pose an environmental risk if they are not disposed of properly through correct destruction. According to a EU Directive (see Sect. 38.2.2.1) all EU Member States shall... 

In order to collect unused medicines from the general public it is often recommended to return the unused medicines to a pharmacy. Pharmacists should establish a safe procedure for medicines waste disposal at the hospital or community pharmacy so that patients and the public are encouraged to return their expired and unwanted medicines and medical devices. Alternatively, pharmacists should provide appropriate informatiOTi to patients on how to safely dispose of expired or unwanted medicines. 

Some patients want to donate unused medicines to Third World countries. There are even organisations that collect surplus medicines to send. Neither the people, nor the environment of the receiving country wants that. The names and instruction leaflets may...

Physicians and patients can contribute by means of reducing the quantity of unused medicines, and return them to a pharmacy. The Swedish classification scheme has also been used to bring enviromnental risk and hazard into the decision of the choice of medicine used [27]. For information regarding novel waste water treatment techniques suitable for removal of pharmaceutical substances, e.g. activated carbon, ozonation, and ultraviolet radiation, the reader is referred to the references [28-32],... 

The environmental burden caused by medicine use is a subject of increasing research. For now, humans seem to run no direct risk. Nevertheless, humans may run an indirect risk by harming the environment. In the short term, hope is placed upon innovations in the field of waste water treatment, and on the contribution of the patient by returning unused medicines to the pharmacy. The development of green medicines , which do not cause harm to the environment, and a responsible use and management of those medicines (green pharmacy) is the ultimate goal.
