The short version
12 companies supply this market — deep enough that no single failure threatens the supply. The generic price is down 13% over the past year, to $1.57 per mL. The brand (Xalatan) runs $108.35 per mL — 69× more. One of its named manufacturing plants, Somerset Therapeutics Private Limited, failed FDA inspectionwithin the last two years — the agency’s most serious outcome. Put together: this looks like a healthy supply — the boring kind, which is exactly what you want.
