Pharmacokinetic and Pharmacodynamic Considerations in Elderly Population
Research
Pharmacodynamics is the study of what the drug does to the body whereas pharmacokinetics is the study of what the body does to the drug. Advance in age reduces CNS function leading to an exaggerated response to CNS active drugs (Cossart et al., 2019). Reduction in liver mass and blood flow thus reducing first-pass metabolism. Aging decreases the renal elimination of drugs. Studies show that after the 40th birthday, the glomerular filtration rate (GFR) decreases by 0.1 mL/sec/m 2/decade (Cossart et al., 2019). Healthcare practitioners should exercise caution while prescribing medication to elderly patients to avoid adverse effects. Medication errors occur among two-thirds of the residents in nursing homes (Cossart et al., 2019). Practitioners should consider the AGS Beers Criteria to avoid conditions that may undermine recovery. The consideration should involve appropriate dosage and medication.
Inappropriate medication can affect the patient or cause toxicity. Statistics indicate that the number of elderly patients seeking care is on the rise. Elderly patients are at risk of multiple health conditions such as diabetes, high blood pressure, cardiovascular conditions, and mental health issues (Sidharta et al., 2019). Prescription of appropriate medication is effective in recovery.
Critical Thinking
I believe practitioners should take extra caution while dealing with elderly patients. Taking caution will prevent their health and prevent adverse effects. I believe elderly patients have a part to play in society. Nursing homes are at risk of legal action if they do not exercise caution while taking care of the patients.
Connecting the Dots
The concept of pharmacodynamics and pharmacokinetics is critical due to the health risks patients face. My community involves elderly people who should receive optimal care. My grandmother died due to medical complications after a wrong prescription. She struggled to live due to the effects of the medication. It is painful for families to watch their elderly parents live in anguish in their last days due to medical errors.
