The short version
20 companies supply this market — deep enough that no single failure threatens the supply. The generic price is down 12% over the past year, to $0.3160 per unit. The brand (Daliresp) runs $14.90 per unit — 47× more. One of its named manufacturing plants, Zhejiang Huahai Pharmaceutical Co., Ltd., 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.
