Diuril (chlorothiazide) Suppliers: Active Manufacturers and Likely Source Market

Last updated: April 28, 2026

Diuril is the brand name for chlorothiazide, a thiazide diuretic. In practice, “Diuril suppliers” typically breaks into two supply lanes: (1) brand-origin/legacy branded distribution and (2) generic chlorothiazide manufacturers supplying wholesalers, hospitals, and specialty distributors.

What companies manufacture chlorothiazide (Diuril) active ingredient for market supply?

The chlorothiazide (Diuril) supply base is dominated by generic manufacturers rather than a single Diuril-only brand-source chain. The firms that matter for procurement are those with (a) established US generic pipelines and (b) the ability to sell chlorothiazide tablets/sterile-ready equivalents through authorized distributors.

Key supplier categories used in procurement (by contract type)

• Generic drug manufacturers (ANDA/authorized generics) producing chlorothiazide tablets
• API manufacturers producing chlorothiazide API for formulation partners
• Wholesalers and specialty distributors handling GxP distribution of finished product

Which supplier channels typically fill “Diuril” demand in the US?

In the US, “Diuril supply” is generally routed through:

• National wholesalers that hold inventory and allocate during shortages
• Hospital group purchasing organizations (GPOs) that contract with generic manufacturers and relabelers
• Authorized distributors that purchase finished product or API to support formulation and repack (where permitted)

These channels are where procurement teams see availability and pricing, not where the final molecule is invented.

How to identify the true supplier for a given Diuril lot (procurement view)?

For any lot-level decision, procurement should anchor on:

• Labeler / NDA-ANDA application-holder on the carton and bottle
• NDC for the specific dosage form and strength
• Manufacturer name listed on the package (finished drug site)
• Lot number and expiration to check whether it aligns with active distribution lots

This is the only way to map “who the supplier is” for a particular Diuril SKU, because finished product labelers can change even when the active ingredient remains the same.

What dosage forms and strengths matter for Diuril sourcing?

Diuril is sold as chlorothiazide (commonly tablet form; historical supply also includes liquid presentations in some markets). For sourcing, the operational point is the NDC by strength and dosage form, since suppliers and lots differ by SKU.

Procurement checklist (must align with the SKU)

• Verify dosage form (tablet vs. other presentation)
• Verify strength (mg per unit)
• Verify route (oral)
• Verify NDC mapping to the supplier/labeler for that SKU

What is the supplier landscape for chlorothiazide in US market practice?

Chlorothiazide is an established generic older medicine; supply is therefore typically:

• Concentrated among a smaller number of generic manufacturers relative to newer drugs
• Sensitive to manufacturing capacity and site compliance events
• Affected by shortage/availability status, which can rapidly shift which labelers wholesalers allocate

Which procurement data sources confirm the supplier for Diuril?

Procurement teams typically confirm supplier using:

• FDA Orange Book (drug product and application-holder mapping for chlorothiazide products)
• FDA Drug Shortages listings (availability and manufacturer/labeler impacts)
• NDC Directory / labeler records (finished product identification by NDC)
• Package labeling (site of manufacture, lot number, expiry)

These sources connect the abstract “chlorothiazide” market to the concrete “this NDC and this lot” supplier reality.

Key Takeaways

• “Diuril suppliers” in practice means chlorothiazide suppliers, and supply comes mainly from generic drug manufacturers, not a single branded chain.
• The actionable supplier for a purchase is the finished drug labeler/manufacturer for your exact NDC and lot, not the chlorothiazide API concept alone.
• Use FDA Orange Book, FDA drug shortages, and the product label to identify the supplier tied to specific Diuril SKUs.

FAQs

1. Is Diuril only sold as a brand?
   No. Diuril’s active ingredient is chlorothiazide, which is commonly available as generics under different labelers.

2. How do I find the supplier for the Diuril product I’m buying?
   Match the NDC and lot to the labeler/manufacturer names on the package and confirm with FDA listings.

3. Do API suppliers decide the finished Diuril supplier?
   Not directly. Finished product labeler/manufacturer is what determines who supplies the drug product you receive.

4. What changes most during shortages?
   Typically the labeler/manufacturer for the same strength NDC and the allocation availability, even when the active ingredient stays constant.

5. What’s the most procurement-relevant identification field?
   The NDC for the specific dosage form and strength, tied to the application-holder/labeler and manufacturing site on the label.
