I don’t have a reliable, single “manufacturing plant cost” for oxymorphone (Opana) because cost varies enormously with what you mean by “plant” (small pilot vs. full commercial API plant vs. finished-dose tablet plant), capacity, regulatory scope (FDA cGMP), and whether the facility is also producing other opioids.
That said, here are the most useful ways to estimate it:
1) Typical cost ranges (very rough, but commonly seen in industry)
For a regulated pharmaceutical manufacturing facility (cGMP), order-of-magnitude budgets often look like:
- Small API pilot / niche API lines: ~$20M–$100M
- Full commercial API facility (multi-purpose or dedicated): ~$100M–$400M+
- Finished-dose solid oral facility (tablets/caps) at scale: ~$50M–$250M
- Specialized opioid handling + extra containment/segregation (for controlled substances) can add a meaningful premium, sometimes tens of millions depending on site and compliance requirements.
So, if someone is asking “what does it cost to build an Opana (oxymorphone) manufacturing plant?” a plausible ballpark for a new, fully compliant commercial facility is often in the neighborhood of ~$100M to $500M+, with wide uncertainty.
2) What drives the cost the most
- Scope: API manufacturing (oxymorphone active pharmaceutical ingredient) vs. just formulation/tableting vs. both
- Capacity target: kg/year vs. tons/year
- Facility type: dedicated opioid facility vs. shared multipurpose plant
- Regulatory/compliance: FDA/DEA controlled substance requirements, validation, GMP documentation
- Containment & segregation: dust control, decontamination design, HVAC, cleaning validation
- Utilities & cleanroom needs: depends on whether it’s solid oral and the process chemistry
- Time to build: longer projects cost more due to escalation
3) Quick clarifying questions (so I can narrow it)
- Do you mean API (oxymorphone) production or finished Opana tablets (formulation/tableting/packaging)?
- Are you estimating a new build or retrofit of an existing cGMP site?
- What production scale are you thinking (e.g., kg/year, million tablets/year)?
If you answer those 3, I can give a tighter estimate range and break it into major cost buckets (site/building, equipment, compliance/validation, staffing ramp, and contingency).
