Alzheimer’s is one of the most common progressive neurological disorders among the elderly caused by dementia. Patients will present with mild to moderate cognitive signs and symptoms at the onset of the disorder, which will progress to severe memory loss with time, as they grow much older (Li et al., 2019). However, several treatment options have been proven to be effective in the management of Alzheimer’s disorder among the elderly. The purpose of this discussion is to illustrate the decision process in selecting the most effective drug, based on pharmacokinetic and pharmacodynamic factors, for treating an elderly patient diagnosed with Alzheimer’s disease.
The assigned case study demonstrates a 76-year-old Iranian male with symptoms of Alzheimer’s disorder. The patient displays strange behavior upon arrival at the clinic reporting symptoms of memory loss, forgetfulness, confusion, and diminished interest in religious activities for the last 2 years. Pharmacokinetic and pharmacodynamic patient factors which contributed to the selection of drugs for this patient include his advanced age, male gender, Iranian race, and presenting symptoms in addition to the mini-mental exam results of moderate dementia. the patient’s diagnosis of Alzheimer’s disorder will also be considered.
Based on the patient history and the pharmacokinetic and pharmacodynamic factors mentioned above, the most appropriate intervention is to initiate Exelon 1.5mg twice daily. Exelon (rivastigmine) is an FFDA-approved drug for treating mild to moderate Alzheimer’s disease (Fish et al., 2019). Previous studies support great effectiveness, and safety profile for use of the drug among the elderly diagnosed with Alzheimer’s (Khoury et al., 2018). The second decision was to increase the dose of Exelon to 4.5 mg twice daily as recommended by most clinical practice guidelines for patients who have displayed great tolerance but with minimal effectiveness. The last decision was to increase the dose further to 6mg twice daily, to promote optimal effectiveness as the patient still displayed limited remission of symptoms with the previous intervention.
Studies show that Exelon when administered appropriately takes between 8 to 12 weeks to completely manage symptoms of Alzheimer’s among elderly patients. As such, with the initial intervention of 1.5mg Exelon twice daily, the patient was expected to display approximately 50% remission of symptoms (Nguyen et al., 2021). The dose was however to be titrated to obtain the optimum outcome, not exceeding 6mg twice daily. The same results were expected with the second and third interventions with no side effects expected.
Just like expected, the patient displayed a minimal reduction of symptoms of Alzheimer’s with no side effects reported with the first intervention. After the dose was increased in the second intervention, the patient reported further remission of symptoms, but at a slow rate, hence increasing the dose in the last intervention, which led to optimal remission of Alzheimer’s symptoms just as expected (Huang et al., 2020).
Alzheimer’s is a common disorder among the elderly compromising their quality of life and well-being. For the patient in the provided case study, it was necessary to administer Exelon at a starting dose of 1.5 mg which was titrated to 4.5mg then 6.5mg twice daily. The patient displayed great effectiveness with this medication in the management of his Alzheimer’s symptoms, with no side effects reported.
