Pharmacokinetics is affected by age-related alterations in drug absorption, distribution, metabolism, and excretion (Katzung et al., 2021; Stauffer et al., 2020). Reduced renal function in elderly patients can impact drug clearance. In LM’s case, the increased creatinine level and reduced eGFR indicate weakened kidney functions affecting drug excretion. Regarding pharmacodynamics, aging could alter the sensitivities and responses to drugs and their receptors (Katzung et al., 2021). Decreased cognition in LM (MMSE score of 18 over a total score of 30) or altered pain perception could potentially reduce the effectiveness of drugs taken. For instance, altered central nervous system function may impact the analgesic response.
Pharmacokinetic Changes
It is significant to make necessary changes in LM medication dose, and drugs with primary renal excretion should be given special consideration, including amlodipine and glyburide (Katzung et al., 2021; Whalen, 2018). Drug clearance could be affected by renal impairment; thus, it can result in the accumulation of drugs, which would raise toxicity levels. Rigorous clinical monitoring should be undertaken due to reduced clearance, limiting effective treatment, and preventing dangerous side effects. Therefore, clinicians are advised to consider each drug’s importance against the therapeutics’ goal versus eliminating the adverse effects of kidney failure.
Pharmacodynamic Changes
Given LM’s pain assessment and cognitive decline, prudent gradual administration of analgesics is warranted for maintaining a fine balance between pain reduction and preserving the cognitive performance of the patient (Katzung et al., 2021; Whalen, 2018). Physical therapy, heat therapy, and massage are non-pharmacological modes of managing pain that should be employed together with pharmacotherapy. That is a comprehensive approach directed towards optimal pain management and preventing cognitive decline, which complies with the principles of geriatric-centered care. Thus, integrating these strategies enables a more integrated and individualized approach to pain management within dementia.
Dose Adjustment
Considering that LM has some impaired renal function, her dose of amlodipine and glyburide needs careful re-titration because these drugs may accumulate in the body, leading to toxication. Closely monitoring for any indications of undesirable and insufficient responses will help adjust the dose to achieve optimal therapy outcomes (Rosenthal & Burchum, 2021). Moreover, frequent renal function tests would help adjust the medication doses according to the changing renal function of LM. Drugs having minimal cognitive consequences are essential for pain management. Such a plan would take a holistic approach that is aligned with the multi-faceted nature of LM’s health needs.
Polypharmacy Review
A comprehensive review of LM’s extensive medication list is imperative to mitigate the risks associated with polypharmacy. Given the patient’s old age, complex nature, and severity of multiple comorbidities, the patient needs to choose only essential drugs. Reducing unnecessary drugs and minimizing exposure to adverse effects and drug interaction facilitates an improved safety profile and maximized effectiveness for pharmacotherapy (Rosenthal & Burchum, 2021). This is the essence of deprescribing, considering what medicines LM needs concerning her current health condition and aspirations.
Collaborative Approach
Addressing LM’s problems of both cardiovascular and pain-related nature calls for involving a multidisciplinary team. Physical therapists play crucial roles in targeted pain management plans, which help ensure proper functioning and mobility (Rosenthal & Burchum, 2021). Pain specialists&r
