Licensing

Sirolimus is licensed for in cases of ciclosporin or tacrolimus and for primary immunosuppression in allograft recipients with low to medium immunological risk.

Referral of patients

The patient will be assessed by a specialist, and the decision to commence sirolimus therapy made. Once stable the specialist will invite the GP to undertake shared care.

Initiation and maintenance of therapy

 Medication history is checked to ensure there are no contra-indications to sirolimus therapy  Blood levels of sirolimus will be monitored  Full blood counts and coagulation tests (including U&Es)  function tests  Initial cholesterol level monitoring

Administration/dosage

Sirolimus should be taken at the same time each day in relation to food. Sirolimus may be added to immunosuppressive therapy after 2-3 months. Initial dosing should start orally at a daily dose of 8mg loading dose followed by 4mg once a day. The dose should then be individualized over the next 2-3 months aiming for a sirolimus drug trough level of 5-12ng/ml. Ciclosporin doses should be tapered during this time to obtain a trough level of 150- 400mg/ml. In the maintenance phase ciclosporin is progressively discontinued over 4-8 weeks and sirolimus dose is increased to give a drug trough level of 12-20ng/ml. Concurrent dosing with corticosteroids is required at this stage. Sirolimus is often swapped with ciclosporin or tacrolimus in cases of nephrotoxicity and there is no tapering of Ciclosporin dose.

Supply

Sirolimus is available as Rapamune® tablets from Wyeth.

Prescribing

Sirolimus is classified on the traffic light system as an Amber1 medication which means that it should only be prescribed under a shared care protocol with additional biochemical monitoring on a level 1 basis as per local enhanced service.

Initiation of sirolimus treatment will be made by the hospital. The hospital will perform the relevant tests before treatment is started and will supply the first three months of medication. Once the patient is considered to be stable the specialists will write to the GP asking for agreement to take over the responsibility for prescribing, detailing dose information and monitoring requirements. Sirolimus is prescribable on FP10.

Adverse effects

Very common Lymphocele, peripheral oedema, , headache, abdominal pain, diarrhoea, constipation, nausea, anaemia, thrombocytopenia, hypercholesterolaemia, hypertriglyceridaemia, hypophosphateaemia, hyperglycaemia, hypokalaemia, increased lactate dehydrogenase, arthralgia, acne, arthralgia, urinary tract .

Common Abnormal healing, , oedema, fungal viral and bacterial infection, tachycardia, VTE, stomatitis, leucopenia, neutropenia, thrombotic thrombocytopenic purpura, abnormal liver function tests, bone necrosis, epistaxis, pneumonia, pneumonitis, , rash, pyleonephritis, proteinuria.

Uncommon , , post transplant lymphoproliferative disorder, pancytopenia, pulmonary haemorrhage.

Rare Lymphodema, hypersensisitivity reactions, anaphylactic reactions, angioedma and vasculitis. Increased risk of malignancies including lymphoma, skin and other tumours appear to be linked to degree and duration of immunosuppression. The incidence is similar to other immunosuppressive agents or therapies. Patients should be counselled with regard to the risk of skin malignancy from exposure to UV light.

Contraindications

Hypersensitivity to the active substance or to any of the excipients. Patients allergic to peanut or soya must not take this medicine. – exclude before starting – if contraception is needed non-hormonal methods should be used). Breastfeeding.

Precautions

Monitor renal function if given in combination with ciclosporin Dose increases may be required in patients from Afro-Caribbean background Hepatic impairment – monitor drug trough levels closely.

Drug Interactions

Increased levels of sirolimus: Inhibitors of CYP3A4 decrease the metabolism and increase levels (e.g. diltiazem, verapamil, , , clarithromycin) Weak inhibitors of CYP3A4 e.g. clotrimazole, fluconazole, cimetidine, danazol) Sirolimus plasma concentrations are increased by ciclosporin

Decreased levels of sirolimus Inducers of CYP3A4 increase metabolism and decrease levels (e.g. rifampicin) Weak inducers of CYP3A4 (St John’s Wort, carbamazepine, phenytoin) grapefruit juice should be avoided Pharmacokinetic interactions may also be observed with gastric prokinetic agents such as cisparide and metoclopramide

Live vaccines should not be administered whilst taking CICLOSPORIN

Monitoring

Blood levels of sirolimus Electrolytes, creatinine and urea Full blood count and coagulation values Liver function tests Cholesterol testing

Area of responsibility for the sharing of care

Sharing of care assumes communication between the specialist, GP and the patient. The intention to share care should be explained to the patient and accepted by them.

Officially the prescribing clinician has clinical responsibility for the medication they have prescribed.

Responsibilities of the General Practitioner
