cycloSPORINE† (sye-kloe-spor-een) Gengraf, Neoral, SandIMMUNE

 Indications

PO, IV: Prevention and treatment of rejection in renal,

cardiac, and hepatic transplantation (with corticosteroids).

PO: Treatment of severe active rheumatoid arthritis

(Neoral only). Treatment of severe recalcitrant

psoriasis in adult nonimmunocompromised patients

(Neoral only). Unlabeled Use: Management of recalcitrant ulcerative colitis. Treatment of steroid-resistant

nephrotic syndrome. Treatment of severe steroidresistant

autoimmune disease. Prevention and

treatment of graft vs. host disease in bone marrow

transplant patients.

Action

Inhibits normal immune responses (cellular and humoral)

by inhibiting interleukin-2, a factor necessary

for initiation of T-cell activity. Therapeutic Effects:

Prevention of rejection reactions. Slowed progression

of rheumatoid arthritis or psoriasis.

Pharmacokinetics

Absorption: Erratically absorbed (range 10–60%)

after oral administration, with significant first-pass metabolism

by the liver. Microemulsion (Neoral) has better

bioavailability.

Distribution: Widely distributed, mainly into extracellular

fluid and blood cells. Crosses the placenta; enters

breast milk.

Protein Binding: 90–98%.

Metabolism and Excretion: Extensively metabolized

by the liver by CYP3A4 (first pass); excreted in

bile, small amounts excreted unchanged in urine.

Half-life: Children—7 hr; adults—19 hr.

†Onset of action in rheumatoid arthritis is 4–8 wk and may

last 4 wk after discontinuation; for psoriasis, onset is2–6wk

and lasts 6 wk following discontinuation.

Contraindications/Precautions

Contraindicated in: Hypersensitivity to cyclosporine

or polyoxyethylated castor oil (vehicle for IV form);

Disulfiram therapy or known alcohol intolerance (IV

and oral liquid dose forms contain alcohol); Patients

with psoriasis receiving immunosuppressants or radiation;

Renal impairment (in patients with rheumatoid arthritis

or psoriasis); Uncontrolled hypertension; OB,

Lactation: Should not be given unless benefits outweigh

risks.

Use Cautiously in: Severe hepatic impairment

(doseprecommended); Renal impairment (frequent

dose changes may be necessary); Active infection; Pedi:

Larger or more frequent doses may be required.

Adverse Reactions/Side Effects

CNS: POSTERIOR REVERSIBLE ENCEPHALOPATHY SYNDROME,

PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY,

SEIZURES, tremor, confusion, flushing, headache,

psychiatric problems. CV: hypertension. GI: HEPATOTOXICITY,

diarrhea, nausea, vomiting, abdominal discomfort,

anorexia, pancreatitis. GU: nephrotoxicity.

Derm: hirsutism, acne, psoriasis. F and E: hyperkalemia,

hypomagnesemia. Hemat: anemia, leukopenia,

thrombocytopenia.Metab: hyperlipidemia, hyperuricemia.

Neuro: hyperesthesia, paresthesia. MS: lower

extremity pain. Misc: gingival hyperplasia, hypersensitivity

reactions, infections (including activation of latent

viral infections such as BK virus-associated nephropathy),

malignancy.
