Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Cyclosporine is a cyclic peptide of 11 amino acids originally isolated from a soil fungus. It binds to cyclophilin inside immune cells, and this complex blocks calcineurin, which reduces activation of T cells and the release of signaling molecules such as interleukin-2.

What the evidence shows

Automatic summaryHuman trials

Cyclosporine is FDA-approved as a prescription drug, with oral and injectable forms approved for preventing organ transplant rejection and for certain cases of rheumatoid arthritis and psoriasis, and an eye drop form (Restasis) approved for increasing tear production in some types of chronic dry eye. It has an extensive human evidence base, with over 1,300 registered trials reaching Phase 4 and more than 35,000 published papers, and it carries well-documented risks including kidney toxicity and increased infection risk.
