Cyclosporine Soft Gel Capsules

Product Description

Cyclosporine lowers your body's immune system. The immune system helps your body fight infections. The immune system can also fight or "reject" a transplanted organ such as a liver or kidney. This is because the immune system treats the new organ as an invader.Cyclosporine is used to prevent organ rejection after a kidney, heart, or liver transplant. Cyclosporine is also used to treat severe psoriasis or severe rheumatoid arthritis.

Pharmacology:

Pharmacodynamic Properties Of Cyclosporine
Used in immunosuppression for prophylactic treatment of organ transplants, cyclosporine exerts specific and reversible inhibition of immunocompetent lymphocytes in the G0-or G1-phase of the cell cycle. T-lymphocytes are preferentially inhibited. The T1-helper cell is the main target, although the T1-suppressor cell may also be suppressed. Sandimmune (cyclosporine) also inhibits lymphokine production and release including interleukin-2.
Pharmacokinetic Properties Of Cyclosporine

• Absorption:
  The absorption of cyclosporine from the gastrointestinal tract is incomplete and variable. The extent of absorption is dependent on the individual patient, the patient population, and the formulation.
• Protein Binding:
  In the plasma, approximately 90% is bound to proteins, primarily lipoproteins. In blood, the distribution is concentration dependent. Approximately 33% to 47% is in plasma, 4% to 9% in lymphocytes, 5% to 12% in granulocytes, and 41% to 58% in erythrocytes.
• Metabolism:
  Hepatic, extensively metabolized by the cytochrome P450 3A enzyme system in the liver. It is also metabolized in the gastrointestinal tract and kidney to a lesser degree. The metabolites are significantly less potent than the parent compound. The major metabolites (M1, M9, and M4N) result from oxidation at the 1-beta, 9-gamma, and 4-N-demethylated positions, respectively.
• Route Of Elimination:
  Elimination is primarily biliary with only 6% of the dose (parent drug and metabolites) excreted in the urine. Only 0.1% of the dose is excreted in the urine as unchanged drug.
