Hydralazine (apresoline) manufacturing plant cost?

See the DrugPatentWatch profile for Hydralazine

Hydralazine (Apresoline) manufacturing plant cost isn’t a single fixed number—what you spend depends heavily on whether you’re:

  1. Making hydralazine as an API (active pharmaceutical ingredient)
  2. Making finished dosage forms (e.g., tablets/injectables) from that API
  3. The scale (e.g., pilot vs commercial),
  4. Regulatory expectations (US FDA cGMP vs EU GMP), and
  5. Whether the plant is new-build or a conversion/fit-out of existing space.

Because hydralazine is an older, generic product, many companies don’t publish detailed capex publicly, so estimates are usually derived from typical cGMP build-out benchmarks.

Typical cost ranges (very rough industry estimates)

A) API manufacturing facility (cGMP for API synthesis)

  • Greenfield new build: often ~$50M to $200M+
  • Smaller/off-the-shelf or modular capacity (if available): could be ~$20M to $80M

B) Finished-dose manufacturing (tablets/capsules or sterile injectable fill-finish)

  • Solid oral dosage plant (non-sterile): often ~$10M to $60M
  • Sterile injectables (fill-finish, aseptic processing): often ~$50M to $150M+, depending on cleanroom class, aseptic fill lines, and capacity

C) If you’re only doing packaging/labelling from sourced API

  • Typically ~$1M to $10M (depends on line count, quality systems, and storage)

What usually drives hydralazine facility cost up/down

  • Route complexity & isolation steps (API route affects number of unit operations, effluent handling, and containment)
  • Wastewater/solvent handling and environmental permits
  • Containment/odors/hazard handling
  • Quality systems: QC labs, stability chambers, microbiology (if sterile)
  • Sterility requirements (for injectable hydralazine): cleanroom and aseptic controls are the big cost driver
  • Capacity: early-phase plants can be dramatically cheaper than full commercial-scale

Quick clarifying questions (so I can narrow it)

  1. Are you estimating API production or finished product (tablets vs injectable)?
  2. Target capacity: tons/year API or units/year of finished product?
  3. Country/region (US/EU/India/China) and the regulatory standard you want to meet?

If you answer those, I can give a tighter order-of-magnitude estimate and outline a typical cost breakdown (buildings/cleanrooms, equipment, utilities, QC lab, validation/engineering, and initial working capital).
