The short version
8 companies supply this market — a reasonable cushion if one runs into trouble. The generic price has fallen 33% in a year, to $0.3184 per unit — and generics that get this cheap tend to get abandoned rather than defended. The brand (Neoral) runs $7.36 per unit — 9.4× more. Put together: this looks like a healthy supply — the boring kind, which is exactly what you want.
