Savaysa™ - Edoxaban
Clinical Application
• Contraindications:
• Active pathological bleeding
• Black Box Warnings:
• Reduced efficacy in nonvalvular atrial fibrillation
patients with CrCl >95 mL/minute – Edoxaban
should not be used in patients with CrCL >95
mL/minute.
• Premature discontinuation of edoxaban increases
the risk of ischemic events
• Spinal/Epidural hematomas – Epidural or spinal
hematomas may occur in patients treated with
edoxaban who are receiving neuraxial anesthesia or
undergoing spinal puncture.

Clinical Application
• Warnings / Precautions:
• May increase the risk of bleeding; serious,
potentially fatal bleeding may occur.
• Not recommended for use in patients with
mechanical heart valves or moderate to
severe mitral stenosis; safety and efficacy
have not been established.
• Patients with DVT and/or PE and body
weight ≤60 kg, reduce dose to 30mg

prior to elective surgery or invasive
procedures.

Clinical Application
• Pregnancy:
• Category C
• Lactation:
• Excretion in breast milk unknown/not
recommended.
• Due to the potential for serious adverse
reactions in the nursing infant, the decision

Drug Facts
• Pharmacology:
• Edoxaban, a selective factor Xa
inhibitor, inhibits free factor Xa and
prothrombinase activity and inhibits
thrombin-induced platelet aggregation.
• Inhibition of factor Xa in the
coagulation cascade reduces thrombin
generation and thrombus formation.

Drug Interactions
• Drug Interactions – Precipitant Drugs:
• P-glycoprotein Inducers: ↓concentration of
Edoxaban

Literature Review
• Phase 3, randomized, double-blind, doubledummy, non-inferiority
• Primary Endpoint: time to the first adjudicated
stroke (ischemic or hemorrhagic) or systemic
embolic event

embolic event, or death from cardiovascular causes
(including bleeding)
• Treatment: 1:1:1 ratio, warfarin, high-dose

Literature Review
• Results: (Median follow-up 2.8yrs)
• The annualized rate of the primary end point of
stroke or systemic embolism
• 1.50% with warfarin
• 1.18% with high-dose edoxaban (P<0.001 for
noninferiority)
• 1.61% with low-dose edoxaban (P=0.005 for
noninferiority)
• The annualized rate of major bleeding
• 3.43% with warfarin
• 2.75% with high-dose edoxaban (P<0.001)
• 1.61% with low-dose edoxaban (P<0.001).

Literature Review
• Conclusion
• Both once-daily regimens of edoxaban
were noninferior to warfarin
• Edoxaban was associated with
significantly lower rates of bleeding and
death from cardiovascular causes.

Savaysa™ - Edoxaban
Summary
• Savaysa™ (Edoxaban) is a factor Xa inhibitor, indicated
to prevent stroke and systemic embolism in non-valvular
atrial fibrillation and to treat DVT and PE. When used in
the treatment of DVT/PE edoxaban requires 5 to 10 days
of initial therapy with a parenteral anticoagulant.
• Edoxaban is typically given as a once daily 60mg dose,
but should be administered at lower doses for patients
with impaired renal or hepatic function or if the patient
weights ≤60 kg.
• Edoxaban should not be used in NVAF patients with
CrCL >95 mL/minute.
• The most common side effects of edoxaban include;
vaginal, cutaneous soft tissue, nose, and GI bleeding.
