XABAREM FILM-COATED TABLETS 10 MG

[SIN17506P]

Indication

Indications

Prevention of venous thromboembolism (VTE) in patients undergoing total hip replacement or total knee replacement surgery.

Xabarem is indicated for the treatment of Deep Vein Thrombosis (DVT) and pulmonary embolism (PE), and for the prevention of recurrent DVT, PE in adults. (see section ‘Warnings and precautions’ for haemodynamically unstable PE patients – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information.)

Dosing

Dosage and method of administration

Prevention of VTE in patients undergoing total hip replacement or total knee replacement surgery
The recommended dose is 10 mg rivaroxaban taken orally once daily. The initial dose should be taken within 6 to 10 hours after surgery, provided that haemostasis has been established.

The duration of treatment depends on the individual risk of the patient for venous thromboembolism which is determined by the type of orthopaedic surgery.

• For patients undergoing major hip surgery, a treatment duration of 5 weeks is recommended.

• For patients undergoing major knee surgery, a treatment duration of 2 weeks is recommended.

If a dose is missed the patient should take the 10 mg Xabarem dose immediately and then continue on the following day with the once daily intake as before.

Treatment of DVT, treatment of PE and prevention of recurrent DVT and PE
The recommended dose for the initial treatment of acute DVT or PE is 15 mg twice daily for the first three weeks followed by 20 mg once daily for the continued treatment and prevention of recurrent DVT and PE.

Short duration of therapy (at least 3 months) should be considered in patients with DVT or PE provoked by major transient risk factors (i.e. recent major surgery or trauma). Longer duration of therapy should be considered in patients with provoked DVT or PE not related to major transient risk factors, unprovoked DVT or PE, or a history of recurrent DVT or PE.

When extended prevention of recurrent DVT and PE is indicated (following completion of at least 6 months therapy for DVT or PE), the recommended dose is 10 mg once daily. In patients in whom the risk of recurrent DVT or PE is considered high, such as those with complicated comorbidities, or who have developed recurrent DVT or PE on extended prevention with Xabarem 10 mg once daily, a dose of Xabarem 20 mg once daily should be considered.

The duration of therapy and dose selection should be individualised after careful assessment of the treatment benefit against the risk for bleeding (see section ‘Warnings and precautions’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

It is essential to adhere to the dosage schedule provided.

If a dose is missed during the 15 mg twice daily treatment phase, the patient should take Xabarem immediately to ensure intake of 30 mg Xabarem per day. In this case two 15 mg tablets may be taken at once. The patient should continue with the regular 15 mg twice daily intake as recommended on the following day.

If a dose is missed during the once daily treatment phase, the patient should take Xabarem immediately to ensure intake of the recommended daily dose. The patient should continue with the regular once daily dose intake as recommended on the following day.

Intake of Xabarem in relation to food
Xabarem may be taken with or without food.

For patients who are unable to swallow whole tablets, Xabarem tablet may be crushed and mixed with water or soft foods such as applesauce immediately prior to use and administered orally. The crushed Xabarem tablet may be given through gastric tubes. Gastric placement of the tube should be confirmed before administering Xabarem. The crushed tablet should be administered in a small amount of water via a gastric tube after which it should be flushed with water (see section’ Pharmacokinetic properties’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Additional information on special populations

Children and adolescents
Safety and efficacy have not been established in children and adolescents below 18 years.
Rivaroxaban is not recommended for use in children or adolescents below 18 years of age due to a lack of data on safety and efficacy.

Geriatric patients
No dose adjustment is required based on age.

Gender
No dose adjustment is required based on gender.

Body weight
No dose adjustment is required based on body weight.

Patients with hepatic impairment
Xabarem is contraindicated in patients with hepatic disease which is associated with coagulopathy leading to a clinically relevant bleeding risk (see sections ‘Contraindications’ and ‘Pharmacokinetic properties’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information). Xabarem may be used with caution in cirrhotic patients with moderate hepatic impairment (Child Pugh B) if it is not associated with coagulopathy (see sections ‘Warnings and precautions’ and ‘Pharmacokinetic properties’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).
No dose adjustment is necessary in patients with other hepatic diseases.

Patients with renal impairment
Limited clinical data for patients with severe renal impairment (creatinine clearance 15 – 29 ml/min) indicate that rivaroxaban plasma concentrations are significantly increased. Therefore, Xabarem is to be used with caution in these patients. Use is not recommended in patients with creatinine clearance < 15 ml/min (see sections ‘Warnings and precautions’ and ‘Pharmacokinetic properties’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

• For the prevention of VTE in adult patients undergoing elective hip or knee replacement surgery, no dose adjustment is necessary in patients with mild renal impairment (creatinine clearance 50 – 80 ml/min) or moderate renal impairment (creatinine clearance 30 – 49 ml/min) (see section ‘Pharmacokinetic properties’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

• For the treatment of DVT, treatment of PE and prevention of recurrent DVT and PE, no dose adjustment from the recommended dose is necessary in patients with mild renal impairment (creatinine clearance 50 – 80 ml/min) (see section ‘Pharmacokinetic properties’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).
  In patients with moderate (creatinine clearance 30 – 49 ml/min) or severe (creatinine clearance 15 – 29 ml/min) renal impairment: patients should be treated with 15 mg twice daily for the first 3 weeks. Thereafter, when the recommended dose is 20 mg once daily, a reduction of the dose from 20 mg once daily to 15 mg once daily should be considered if the patient’s assessed risk for bleeding outweighs the risk for recurrent DVT and PE. The recommendation for the use of 15 mg is based on PK modelling and has not been studied in this clinical setting (see sections ‘Warnings and precautions’, ‘Pharmacodynamic properties’ and ‘Pharmacokinetic properties’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).
  When the recommended dose is 10 mg once daily, no dose adjustment from the recommended dose is necessary.

Converting from Vitamin K Antagonist (VKA) to Xabarem
For patients treated for DVT, PE and prevention of recurrence, VKA treatment should be stopped and Xabarem therapy should be initiated once the INR is ≤2.5.

When converting patients from VKAs to Xabarem, INR values will be falsely elevated after the intake of Xabarem. The INR is not valid to measure the anticoagulant activity of Xabarem, and therefore should not be used (see section ‘Interactions’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Converting from Xabarem to Vitamin K antagonists (VKA)
There is a potential for inadequate anticoagulation during the transition from Xabarem to VKA. Continuous adequate anticoagulation should be ensured during any transition to an alternate anticoagulant. It should be noted that Xabarem can contribute to an elevated INR.

In patients converting from Xabarem to VKA, VKA should be given concurrently until the INR is ≥2.0. For the first two days of the conversion period, standard VKA dosing should be used followed by VKA dosing guided by INR testing. While patients are on both Xabarem and VKA, the INR should not be tested earlier than 24 hours (after the previous dose but prior to the next dose of Xabarem. Once Xabarem is discontinued INR testing may be done reliably 24 hours after the last dose (see section ‘Interactions’ – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Converting from parenteral anti-coagulants to Xabarem
For patients currently receiving a parenteral anticoagulant, start Xabarem 0 to 2 hours before the time of the next scheduled administration of the parenteral drug (e.g. LMWH) or at the time of discontinuation of a continuously administered parenteral drug (e.g. intravenous unfractionated heparin).

Converting from Xabarem to parenteral anti-coagulants
Discontinue Xabarem and give the first dose of parenteral anticoagulant at the time that the next Xabarem dose would be taken.
