Insights

Direct oral anticoagulants (DOACs) are effective and safe for elderly atrial fibrillation patients. These anticoagulants offer a good alternative to older therapies, showing high compliance and efficacy in real-world use.

Area of Science:

  • Cardiology
  • Pharmacology
  • Geriatrics

Background:

  • Four direct oral anticoagulants (DOACs) are approved for atrial fibrillation (AF) treatment.
  • Clinical trials demonstrate DOAC efficacy and safety, but real-world data in elderly populations is limited.

Purpose of the Study:

  • To assess the effectiveness and safety of DOACs in patients aged 75 years and older with AF.
  • To evaluate the impact of switching from previous anticoagulation treatments to DOACs in this demographic.

Main Methods:

  • A prospective study included consecutive patients aged 75 years and older with AF who were switched to DOACs.
  • Follow-up assessments were conducted at 3, 6, and 12 months via phone and in-person visits.

Main Results:

  • 143 elderly patients (mean age 81 years) were switched to DOACs, with a median follow-up of 9.6 months.
  • Four minor bleedings and one nonmajor bleeding event occurred, managed by dose adjustment or temporary cessation.
  • Two strokes were reported in patients on dabigatran 110 mg, with no serious sequelae; 2.8% experienced adverse effects like nausea.
  • Four deaths occurred, unrelated to anticoagulation therapy.

Conclusions:

  • DOACs represent a viable and effective alternative to traditional anticoagulants for elderly patients with AF.
  • High patient compliance and a favorable safety/efficacy profile position DOACs as a preferred option for long-term anticoagulation in older adults.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...
