CONCLUSION
BACKGROUND
The value of unused medicines throughout the world
was immense :
Saudi Arabia & Gulf countries 2002 US150 million,
Texas, USA 2003: US 26,000
Puy-de-Dome,France 2001 : 87456FF.
Hisham S. et al 2002, Kevin Garey et al 2004
There is little published information on why unused
medicines are returned to the pharmacies.
S.Braybrook et al. The Pharmaceutical Journal (TPJ)
Sept.1999
The waste of medicines represents the end-point of
sub-optimal drug use and is an anti-thesis of good
medicines management.
Adam Mackridge et al TPJ January 2004
AIM OF STUDY
To obtain preliminary data on unused
medicines, reasons for nonconsumption, storage and disposal
practices of unused medication among
Putrajaya Hospital patients.
OBJECTIVE
1
2
To assess public
awareness on
storage
conditions and
disposal.
To identify types
of unused drugs

costs of the
unused drugs.
METHODOLOGY
Single-centered,
Prospective,
observational
study.

distributed.
Public who return medications
voluntarily were asked to fill an
investigator - assisted questionnaire.
Patients were given token of
appreciation for their participation.
EXCLUSION CRITERIA
Drugs returned from the ward.
Expired drugs from hospitals, clinics
and other institutions.
Drugs returned from non governmental
sources and unidentifiable/
unquantifiable drugs were accepted but
not included in the analysis.
DATA ANALYSIS
Drugs returned were assessed in terms
of type, source, quantity, expiry,
reasons for returning and ownership.
Cost of the drugs were accounted
according to the Putrajaya Hospital
purchase price at the end of 2006.
Data gathered were analysed using
Microsoft Excel.

RECOMMENDATIONS
The project should be continuous and be made a
regular program in more centers :
i) to account the amount of wastage;
ii) to encourage environmentally safe ways to dispose
drugs
iii) to identify medication wastage related issues
including non compliance, ADRs and side effects.
Physicians are recommended to practice prudent
prescribing in chronic diseases.
Patients should be educated on the need and
importance of adherence to medication, reporting of
side effects, ADRs, proper storage and disposal and
appreciation of the value of the drugs dispensed.
A more comprehensive study is recommended to
investigate the issue of excessive stock.
CONCLUSION
Pharmacist involvement in medication
management review could address
issues of over-stocking, drug storage,
compliance, side-effects and/or adverse
drug reaction monitoring. The study
also indicates the need for an
appropriate method of disposal of
unused medication.
