Medication (And Its Dosage) And Age (And Physical Change)
Metabolism:
Our metabolism slows down as we become older. Since our bodies digest drugs more slowly as a result, the effects linger longer. Certain drugs may even build up in the body, causing negative side effects. As a result, it’s crucial to modify medicine dosages for older persons in accordance with their metabolic rate.

Absorption:
The capacity of our gastrointestinal tract to absorb drugs reduces with age. As a result, it’s possible for drugs to take longer to start working after they’ve entered the bloodstream. When providing medications to older persons, it’s crucial to take the route of administration into account because some routes may be more effective than others.
Distribution:
The way that medicines are distributed throughout the body may change as we age. Older persons often have a higher body fat percentage, which can lead to the accumulation of various drugs in fatty tissues. The chance of negative effects may rise as a result. When providing drugs to older persons, it’s crucial to take the drug’s distribution characteristics into account.
Elimination:
The body’s ability to rid itself of drugs can be impacted by age-related changes in kidney and liver function. Drugs may be eliminated more slowly in older persons as a result of possible impaired renal and liver function. The chance of negative effects may rise as a result. As a result, it’s crucial to modify drug dosages for older persons according to their liver and kidney function.
Polypharmacy:
To treat their medical concerns, older folks are frequently given several prescription drugs. The risk of negative medication responses and drug interactions may rise as a result, though. It might be difficult to adequately regulate medicine dosages when there is polypharmacy. Before administering medications to older folks, it’s crucial to weigh the advantages and disadvantages of each one.
Medication side effects:
Drug side effects may differ for older persons compared to younger adults. This is owing to the possibility that their bodies may respond to the medication differently as they age. Moreover, the negative effects of medication may affect older persons more severely. When prescribing drugs to elderly patients, it’s crucial to keep an eye out for any potential side effects.
Cognitive function:
A person’s capacity to appropriately manage their prescriptions can be impacted by age-related changes in cognitive function. Elderly people could have trouble remembering to take their drugs or comprehending the directions on the label. This can result in non-adherence to medicines and a higher risk of side effects. When providing medications to elderly patients, it’s crucial to take cognitive function into account and to give detailed instructions.
Functional status:
The ability of an individual to adequately manage their prescriptions might be impacted by age-related changes in physical function. Elderly people could have trouble swallowing medicines or opening pill bottles. This can result in non-adherence to medicines and a higher risk of side effects. When providing pharmaceuticals to older persons, it’s crucial to take their functional state into account and to use the proper medication formulations.
Pharmacokinetics and Pharmacodynamics:
The study of drug absorption, distribution, metabolism, and elimination in the body is known as pharmacokinetics. Contrarily, pharmacodynamics describes how drugs interact with the body to have a therapeutic impact. Medication doses may need to be adjusted as a result of age-related pharmacokinetic and pharmacodynamic changes that may affect how well older persons respond to medication. When prescription drugs to older persons, it is crucial to take pharmacokinetics and pharmacodynamics into account.
Comorbidities:
Older persons may have a number of chronic medical illnesses that call for the administration of numerous drugs. Comorbidities can alter how drugs function in the body, requiring adjustments to dosage. To guarantee the safety and efficacy of medications, it is crucial to take comorbidities into account when prescribing medications to older persons and to coordinate care with other healthcare professionals.
Medication dosages for elderly persons should be modified in light of these characteristics. For medications that are processed in the liver or removed by the kidneys, for instance, smaller doses could be necessary. The therapeutic index of the drug, or the range between the therapeutic dose and the dangerous dose, should also be taken into account. The therapeutic dose needed for older persons to experience the same impact as younger adults may be lower.
In conclusion, there is a strong correlation between drug dosage and aging-related bodily changes. When prescription drugs to older persons, it’s crucial to take age-related changes in metabolism, absorption, distribution, and excretion into account. To ensure secure and efficient medication administration in older persons, additional factors such polypharmacy, drug side effects, cognitive function, and functional status should also be taken into account.
Deprescribing challenges
Older persons frequently continue taking certain medications even when they are no longer necessary or when the hazards exceed the benefits. This may be the result of a number of factors, such as resistance to change, ignorance of the medicine, or poor communication with medical professionals. For older folks, however, continuing to take needless or potentially hazardous medications can have major negative effects. It may result in negative drug reactions, drug interactions, a higher risk of falling or other health issues, or all three. Also, it can lower quality of life and result in needless healthcare expenses.
As a result, it’s critical for healthcare professionals to periodically examine an older adult’s prescription schedule and weigh the advantages and disadvantages of each drug. Deprescribing, the process of tapering or terminating prescriptions that are no longer necessary or hazardous, may be involved in this. Deprescribing can assist older persons’ overall health outcomes by lowering their risk of adverse medication responses and drug interactions.
Yet, deprescribing can be problematic, as older persons may be resistant to changes in their pharmaceutical regimen. Hence, while making decisions about medication management, healthcare professionals should be transparent with older persons and their carers, clearly explain the risks and advantages of the medicine, and take the older adult’s objectives and preferences into account.
Healthcare professionals can promote healthy lifestyle choices in older persons, including as routine exercise, a good diet, and stress management skills, in addition to deprescribing. These actions can aid in enhancing overall health outcomes and lowering the demand for specific medications.
In order to ensure drug adherence, healthcare providers should work with elderly patients and their carers. This may entail giving precise prescription instructions, utilising pill organisers or reminder programmes, and, whenever possible, streamlining medication regimes. Also, it’s crucial to keep an eye out for any potential drug interactions or unpleasant reactions in older persons and to change prescription dosages as necessary.
The Beers Criteria, a list of possibly unsuitable drugs for usage in older persons, should also be known to healthcare practitioners. The drugs on this list are those that, because of age-related changes in drug metabolism, elimination, and sensitivity, are more likely to have negative effects on older persons. Medical practitioners should either refrain from prescribing drugs on the Beers Criteria list or use them cautiously and under close supervision.
Healthcare practitioners should promote healthy lifestyle choices in older persons in addition to medication management to improve their health and decrease the demand for medications. This can include managing stress, eating well, exercising frequently, and getting enough sleep. By engaging in these practises, older persons can retain their physical and cognitive abilities as well as prevent or treat chronic health conditions.
Finally, when providing drugs to older persons, dose and age-related physical changes must be taken into account. In addition to taking into account other elements including polypharmacy, pharmaceutical side effects, cognitive function, and functional status, healthcare practitioners should alter medication doses based on age-related changes in metabolism, absorption, distribution, and excretion. Together with ensuring medication adherence, monitoring for possible negative drug reactions or interactions, and promoting healthy lifestyle practises, they should work with elderly people and their carers. Healthcare practitioners can optimise health outcomes and raise quality of life by managing older individuals’ medications holistically.
