A process for preparing an emulsion composition comprising a cyclosporin, a rapamycin or an ascomycin or a derivative thereof as active agent, which process comprises the step of admixing to a placebo fat emulsion a concentrate comprising a) the active agent, b) a stabiliser selected from a phospholipid, a glycolipid, a sphingolipid, a diacylphosphatidyl glycerol, an egg-phosphatidylglycerol, a soy-phosphatidylglycerol, a diacylphosphatidylglycerol, or a salt thereof; or a saturated, mono- or di-unsaturated (C12-24) fatty acid, or a salt thereof, and c) an organic solvent, wherein the weight ratio of active agent to stabiliser is between 400:1 and 0.5:1. The invention also provides ready-to-use emulsions, e.g. for intravenous administration, prepared using the above process.
