Adverse drug reactions in the elderly

BACKGROUND: Liver injury is the hallmark adverse reaction of endothelin receptor antagonist (ERA). Since the first drug, bosentan has been widely used in clinical practice, hepatotoxicity has been accompanied by the history of ERA. The new ERA has been proven to have a lower liver risk but the current research findings are inconsistent. ERA-based targeted drug combinations are commonly used in the treatment of pulmonary arterial hypertension, where the risk of liver injury is difficult to estimate...

BACKGROUND: Coronary artery disease (CAD) is a leading cause of global cardiovascular mortality. Refractory angina pectoris, a manifestation of CAD, requires effective drug treatments. Pericarpium Trichosanthis injection, a traditional Chinese medicine, improves cardiovascular symptoms, while nicorandil alleviates spasms and angina. Both have potential in treating CAD. AIM: To investigate the therapeutic effects of combining Pericarpium Trichosanthis injection and nicorandil in elderly patients suffering from refractory angina caused by coronary heart disease...

OBJECTIVE: We aimed to investigate the effects of methoxamine to prevent hypotension in the elderly with intraspinal anesthesia (IA) on myocardial injury and cardiac function. PATIENTS AND METHODS: A retrospective study was conducted by enrolling sixty elderly patients who underwent femoral head replacement (FHR) under IA in our hospital from August 2019 to August 2020. The patients were divided into two groups according to the random number table method. In the control group (CG) (30 patients), 5 mg of ephedrine was administered sedately when patients developed hypotension (20% below basal blood pressure)...

BACKGROUND/AIM: Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with the functional impairment of multiple joints and the destruction of bone and cartilage. Methotrexate (MTX) is a first-line drug commonly used to treat RA; however, even low doses of MTX can potentially cause rare but severe adverse reactions, such as neutropenic enterocolitis (NE), a life-threatening disease characterized by intestinal mucosal damage and immunodeficiency. CASE REPORT: Here, we report on an 82-year-old RA patient who developed life-threatening NE after ten years of low-dose MTX treatment...

The human body is subservient to the age-related changes that affect not only the outer appearance, but also organs and tissues. They also concern the processes of pharmacokinetics and dynamics. This means that the absorption, distribution and metabolism of drugs used by an elderly patient will be slowed down. Therefore, it becomes necessary to prescribe a special dosing regimen for older people. An actual problem is also that with age, many patients require more drugs than young people. This increases the risk of side effects, because many drugs are difficult to combine with each other...

Like most organs, the renal system decreases in function as we age. In the elderly, chronic kidney disease is common. When patients with chronic kidney disease take nephrotoxic medications, they are more likely to suffer adverse drug reactions, be hospitalized, and spend an extended period in the hospital. Calculating the renal clearance of a drug dose based on its glomerular filtration rate, or creatinine clearance, is necessary. Multiple tools are available for identifying renally inappropriate medications (RIMs)...

Awareness related to the risk/benefit profile of therapies used in paediatric and elderly patients is limited. We carried out a study, called the MEAP 3.0 study, to collect and analyse evidence of adverse drug reactions (ADRs) and drug-drug interactions (DDIs) that occurred in frail populations under polypharmacy in a real-world setting. Data were retrieved from reports of ADRs and pharmacological counselling from patients treated in hospitals and territorial health services. We collected 2977 ADRs reports and identified 'anti-infectives for systemic use' and 'cardiovascular system' as the most frequently implicated pharmacological classes in under-18 and over-65 patients, respectively...

BACKGROUND: Fruquintinib has demonstrated significant improvement in overall survival (OS) among previously treated metastatic colorectal cancer (mCRC) patients. However, the utilization of fruquintinib has been constrained by various toxicities, such as hand-foot skin reaction (HFSR) and hypertension, particularly in elderly patients with reduced tolerance to the standard dosage. This study aims to investigate the efficacy and safety of fruquintinib dose-escalation strategy for elderly refractory mCRC patients...

The evaluation of the skin of the decedent is an essential component of the assessment by the forensic pathologist or the medical examiner. Age-associated cutaneous changes, primary diseases of the skin, and systemic conditions with mucocutaneous manifestations can be present. Importantly, several dermatoses can be misinterpreted for traumatic injuries; specifically, adverse reactions to medications can mimic assault, burns, elder abuse, and mutilation or torture. A male with corticosteroid-induced dermatitis mimicking an acute burn is described...

There is limited literature on managing chronic lead exposure from non-removable sources such as lead fragments. In this case report, we present the complexities and clinical considerations involved in treating an elderly patient who sustained a comminuted knee fracture due to a gunshot wound, complicated by retained lead fragments. This case highlights the absence of comprehensive guidelines for managing chronic lead exposure when complete fragment removal is impractical. It also emphasizes the importance of a multidisciplinary approach to decision-making, while considering patient autonomy in such unique clinical scenarios...

Due to the large cost of joint replacement for surgical treatment of knee osteoarthritis, there are many complications in elderly patients, and there are many contraindications to surgery, and conservative treatment is still based on drugs. To further evaluate the efficacy and safety of sodium hyaluronate combined with celecoxib for the treatment of osteoarthritis of the knee. In total, 202 studies were screened, with a final selection of 9 RCTs involving 2339 participants; of these, 9 RCTs were included in the final meta-analysis...

The European Medicine Agency (EMA) has defined Adverse Drug Reactions (ADRs) as "a noxious and unintended response to a medicine", not including poisoning, accidental, or intentional overdoses. The ADR occurrence differs based on the approach adopted for defining and detecting them, the characteristics of the population under study, and the research setting. ADRs have a significant impact on morbidity and mortality, particularly among older adults, and represent a financial burden for health services. Between 30% and 60% of ADRs might be predictable and preventable, emerging as a result of inappropriate prescription, drug chemistry inherent toxicity, cell-specific drug toxicity, age- and sex-related anomalies in drug absorption, distribution, metabolism, and elimination (ADME), and drug-drug interactions (DDIs) in combination therapies or when a patient is treated with different drugs for concomitant disorders...

Dementia is a syndrome of global and progressive deterioration of cognitive skills, especially memory, learning, abstract thinking, and orientation, usually affecting the elderly. The most common forms are Alzheimer's disease, vascular dementia, and other (frontotemporal, Lewy body disease) dementias. The etiology of these multifactorial disorders involves complex interactions of various environmental and (epi)genetic factors and requires multiple forms of pharmacological intervention, including anti-dementia drugs for cognitive impairment, antidepressants, antipsychotics, anxiolytics and sedatives for behavioral and psychological symptoms of dementia, and other drugs for comorbid disorders...

INTRODUCTION: Medication Therapy Management (MTM) is identified as a group of services provided to the patient in order to optimize the medication use in order to mitigate adverse drug reactions (ADRs), drug-drug interaction (DDI), and polypharmacy. Elderly populations above 60 years old are at high risk for Medication-related Problems (MRPs) due to several factors. Therefore, MTM programs showed good contributions globally regarding enhancing medication use in the elderly population...

COVID-19 is still a world disaster; however, its vaccination is globally available. Liver and gastrointestinal disturbances occur in patients infected with COVID-19 at varying incidences. Aging decreases the functions of the liver. Thus, the elderly have a weaker response to the COVID-19 virus. The COVID-19 virus affects the liver directly through direct and indirect mechanisms. It directly affects the renin-angiotensin system or indirectly causes sepsis, uncontrolled immune reactions, drug-related hepatic injury, and cytokine storm...

OBJECTIVE: The study aimed to assess the impact of the enhanced recovery after surgery (ERAS) pathways and the reduced use of opioids on postoperative outcomes in elderly colorectal cancer (CRC) patients who underwent laparoscopic surgery under general anesthesia (GA). PATIENTS AND METHODS: Clinical data from 99 elderly patients who underwent laparoscopic CRC surgery in the First Affiliated Hospital of Hebei North University from April 2021 to April 2023 were retrospectively analyzed and grouped based on the method of pain control measures received...

Background: Polypharmacy, defined as the simultaneous use of multiple medications by a patient, is a worldwide problem of rising prevalence. Paving the way for drug interactions, adverse drug reactions and non-adherence, it leads to negative health outcomes, increased use of healthcare services and rising costs. Since it is closely related to multimorbidity, it peaks in older adults. So far, not many polypharmacy management programs in the elderly have been introduced in practice. However, due to the rapid ageing of European societies, there is an urgent need to implement them more widely...

BACKGROUND: Medication adherence is essential for optimizing treatment outcomes in elderly patients who frequently contend with multiple chronic diseases requiring pharmacological interventions. Mild cognitive impairment (MCI) is a prevalent cognitive disorder among the elderly population, but its impact on medication adherence among elderly patients is still uncertain. This cross-sectional study aimed to investigate the impact of MCI on medication adherence among elderly patients. METHODS: A cross-sectional study of 436 elderly patients with common chronic diseases aged 60 years and above was conducted...

OBJECTIVE: This study aims to compare the efficacy and safety of drug-coated balloon (DCB) and standard angioplasty balloon (SAB) in the treatment of intrastent restenosis (ISR) after lower extremity ASO following rotarex thrombus removal. METHODS: 94 patients with ISR after lower extremity ASO were selected and divided into DCB group (47 cases) and SAB group (47 cases). After patients were treated with DCB and SAB methods, six months after discharge care, the therapeutic effect, lower extremity dorsal arterial blood flow, ankle-brachial index, lameness distance, hemorheology, endothelial function indexes, and lipid levels were measured...

The hepatotoxic potential of diclofenac, a commonly used non-steroidal anti-inflammatory agent, is well established in literature. However, cases of diclofenac-induced liver disease have occurred almost exclusively with the oral formulation of this medication. We report the case of an elderly man with Paget's disease and osteoarthritis who developed acute hepatotoxicity, as evidenced by laboratory diagnostics, four months after use of topical diclofenac 1% gel. Once diclofenac gel was discontinued, repeat blood work three weeks after discharge demonstrated return of liver function tests to baseline...
