When working with Cyclosporine, a calcineurin inhibitor that suppresses the immune system to prevent organ rejection and treat autoimmune conditions. Also known as Neoral, it belongs to the broader group of immunosuppressant, drugs that deliberately lower the body’s immune response medications. Doctors rely on it for organ transplant, the surgical transfer of a healthy organ from a donor to a recipient patients and for conditions like psoriasis or rheumatoid arthritis. Because it shares many properties with Tacrolimus, another calcineurin inhibitor often used as a comparative alternative, understanding cyclosporine’s nuances helps you pick the right therapy and avoid surprises.
Cyclosporine blocks the activation of T‑cells by inhibiting the enzyme calcineurin, which stops the release of interleukin‑2, a key signal for immune activity. This mechanism makes it ideal for keeping a transplanted organ from being attacked. Typical starting doses range from 2 mg/kg to 5 mg/kg per day, split into two doses, but the exact amount hinges on blood level monitoring. Doctors measure trough concentrations because the drug’s window between efficacy and toxicity is narrow. Side effects can include kidney strain, high blood pressure, gum overgrowth, and tremors. If you notice sudden swelling, unusual fatigue, or severe headaches, it could signal toxicity that needs immediate attention. Drug interactions are a major concern: CYP3A4 inhibitors like ketoconazole can raise cyclosporine levels dramatically, while inducers such as rifampin can lower them, risking organ rejection. Even common foods, like grapefruit juice, can tweak metabolism, so consistent diet habits matter.
