NEGATIVE INFLUENCE OF POLY-PHARMACY

Languages Department 
Supervisor – senior teacher Umarova M.B. 
Poly-pharmacy refers to the use of multiple medications or the use of medicine that is not indicated 
for a disease condition or the ineffective or inappropriate use of medications than they are medically 
necessary. The use of medicines that constitute therapeutic duplication also amounts to Poly-
Pharmacy. A rise in life expectancy in many regions around the world has resulted in the number of 
people aged 65 years and above. 
Poly-pharmacy is, therefore, very more prevalent in older adults. Self-medication and self-
prescriptions of drugs and a prescribing cascade also cause poly-pharmacy. A prescribing cascade 
entails patients take medications and then exhibit the side effects, which are then misinterpreted by 
the health care professional as a disease symptom. Ineffective communication and coordination 
between the patients and the health care provider resulting in multiple prescriptions in different 
healthcare settings is also a major cause of Poly-pharmacy. 
A study of ambulatory Medicare patients revealed that the most common drug classes prescribed in 
a 1-year period were cardiovascular agents, antibiotics, diuretics, analgesics, antihyperlipidemics, 
and gastrointestinal agents. This result is to be expected because the drugs reflect the common 
conditions that occur in community-dwelling elders. The most common nonprescription 
medications consumed by older adults were analgesics (aspirin, acetaminophen, and ibuprofen), 
cough and cold medications (diphenhydramine and pseudoephedrine), vitamins and minerals 
(multivitamins, vitamins E and C, calcium), and herbal products (ginseng, Ginkgo biloba extract). 
Other nonprescription medications commonly used by elderly patients include antacids and 
laxatives.
The risk for development of adverse drug reactions is strongly linked with multiple comorbidities 
and poly-pharmacy. Man of science explains that as the body ages, it processes medicines 
differently. Medicines also stay in the body for longer periods and medicines are highly 
concentrated in some specific parts of the body due to diminished circulation and reduced cardiac 
output. Reduced renal and liver functions also influence how drugs are metabolized making old 
people at a very high risk of suffering from adverse drug reactions. 
Old people are more predisposed to drug interactions. The probability of drug interactions increases 
with an increase in the number of medications with a fifty percent risk when a patient is taking five 
to ten medications and a 100 percent risk when a patient is taking more than twenty medicines. 
Many patients are living longer with chronic disease conditions requiring multiple drug therapy, and 
the risk of drug interactions is a major concern for healthcare professionals.
Multiple medications are linked to many geriatric issues like urinary incontinence and increased 
risk of suffering from lower urinary tract infections. Other geriatric syndromes are cognitive 
impairment and loss of balance that results in fractures and falls. 


Poly-pharmacy results in an increase in healthcare costs for the patient and the healthcare system. 
Some data suggest that poly-pharmacy results in an increase in healthcare costs by thirty percent, 
due to potentially inappropriate medication prescribing, increased hospital visits and the associated 
adverse drug reactions associated with poly-pharmacy. 
Poly-pharmacy also affects a patient’s nutritional status. Patients taking more than ten medications 
have poor nutrition and a risk of malnutrition. Adverse drug effects may also affect the appetite of 
patients resulting in poor eating habits such as taking unhealthy and unbalanced diet.
