The short version
6 companies supply this market — a reasonable cushion if one runs into trouble. The generic price has fallen 35% in a year, to $4.20 per unit — and generics that get this cheap tend to get abandoned rather than defended. The brand (Protonix Delayed-Release) runs $14.08 per unit — 3.4× more. Put together: this looks like a healthy supply — the boring kind, which is exactly what you want.
