Concerns with polypharmacy and elderly groups are reduced medication adherence, increased fall risk, cognitive function impairment, and adverse drug reaction. [11] Almost 75% of clinic visits result in people obtaining a written prescription. [12] [13] More careful prescribing practices could increase medication adherence in elderly people.
[2] [3] They emphasize deprescribing medications that are unnecessary, which helps to reduce the problems of polypharmacy, drug interactions, and adverse drug reactions, thereby improving the risk–benefit ratio of medication regimens in at-risk people. [4] The criteria are used in geriatrics clinical care to monitor and improve the quality of ...
An FDA database that collects reports of adverse drug reactions from doctors and others shows 23 deaths of patients taking Leqembi. Holman at Eisai said it would be incorrect to assume the deaths ...
Adverse drug reaction. This could occur when a patient has an allergic response to a medication. [7] Inappropriate adherence. This could occur when a patient chooses not to or forgets to take a medication. [7] Needs additional drug therapy. This could occur when a patient needs more medication to treat their condition. [7]
[2] [3] Elderly patients are often prescribed more than one drug within the same drug class, and doctors may treat the side effects of prescribed drugs with even more drugs, which can overwhelm the patient. [4]
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
This polypharmacy, in combination with geriatric status, may increase the risk of drug interactions or adverse drug reactions. [7] Pharmacokinetic and pharmacodynamic changes arise with older age, impairing their ability to metabolize and respond to drugs. Each of the four pharmacokinetic mechanisms (absorption, distribution, metabolism ...
It also increases the possibility of adverse medication reactions (side effects) and drug-drug interactions. High pill burden has also been associated with an increased risk of hospitalization, medication errors, and increased costs for both the pharmaceuticals themselves and for the treatment of adverse events.
