Silodosin API Manufacturer in India – Direct Factory Sourcing
Silodosin has moved firmly into its post-patent generic era, and with the global BPH therapeutics market projected to exceed $4.5 billion by 2027, demand for reliable, well-documented API supply has grown right alongside it. If you’re searching for a Silodosin API manufacturer in India, the same rule applies here as with any high-demand generic API: not every listed “supplier” is the actual factory producing the material, and buying from the wrong type of source affects your documentation, batch consistency, and ultimately your finished product’s regulatory standing.
This guide covers what Silodosin API actually is, why grade selection matters more here than for many other APIs, and what to verify in a manufacturer before you order.
What Is Silodosin API?
Silodosin (CAS 160970-54-7) is a highly selective alpha-1A adrenergic receptor antagonist used in the treatment of benign prostatic hyperplasia (BPH). It works by relaxing smooth muscle in the prostate and bladder neck, improving urinary flow and reducing BPH-related symptoms. Its defining clinical characteristic is its high selectivity for the alpha-1A receptor subtype specifically, which gives it a meaningfully different side-effect profile notably reduced dizziness and orthostatic hypotension compared to older, less selective alpha-blockers.
Why Grade Selection Matters for Silodosin Specifically
Silodosin was originally developed by Kissei Pharmaceutical in Japan, which makes Japanese Pharmacopoeia (JP) grade a particularly relevant specification for this molecule sourcing closer to its pharmacopeial country of origin can be a meaningful documentation and quality consideration for formulators, especially those targeting Japanese-influenced regulatory frameworks or markets that recognize JP standards. Indian Pharmacopoeia (IP/IH) grade remains the more cost-effective option for domestic Indian formulation and many export markets that don’t specifically require JP-referenced documentation.
Confirming which grade your target market or finished-product registration actually requires rather than defaulting to whichever a supplier happens to have on hand is worth getting right before you place your order.
Why Buying Direct From the Manufacturer Matters
As a fast-growing generic API, Silodosin listings are increasingly common across B2B chemical marketplaces, and not every listed supplier is the facility actually producing it. Sourcing direct from the manufacturer changes what you get in several concrete ways:
- Factory pricing, without a trader’s resale markup added on top.
- Batch-consistent quality, since the material comes from a single controlled production process.
- Direct access to documentation, including grade-specific CoAs and GMP certification tied to the actual production facility.
- Faster resolution if a technical or documentation question comes up, since you’re dealing with the people who actually manufactured the batch.
What to Look for in a Silodosin API Manufacturer India
- WHO-GMP certification — confirm the certificate names the specific facility producing your material.
- Grade availability matching your requirement — confirm whether you need IH or JP grade before finalizing your order, and that your supplier can consistently provide it.
- Purity and impurity profile documentation — request current HPLC assay data and related-substances information.
- Facility transparency — a genuine manufacturer can confirm their production site location and is generally open to a facility audit or virtual walkthrough.
- Consistent supply capability — confirm current lead times and production capacity directly rather than assuming availability.
Silodosin API at Chemox Pharma
Chemox Pharma manufactures Silodosin API in both IH and JP grades at our WHO-GMP certified facility in Dahej, Gujarat — we are the factory, not a reseller. Our in-house R&D centre supports the quality consistency this alpha-1A selective molecule requires, and our team can confirm current grade availability, documentation, and lead times directly for your specific formulation need.
Questions to Ask Before You Order
- Can you confirm your facility location and share your WHO-GMP certificate?
- Do you supply IH grade, JP grade, or both — and which does my target market require?
- Can you provide a batch-specific CoA matching my order?
- What is your current production lead time and capacity?

FAQs
Q: What is Silodosin’s CAS number?
Silodosin’s CAS number is 160970-54-7.
Q: Why does grade selection matter more for Silodosin than for some other APIs?
Silodosin originated with Kissei Pharmaceutical in Japan, making JP grade a particularly relevant specification for certain markets, alongside the more cost-effective IH grade commonly used for domestic Indian and export formulation.
Q: Is Chemox Pharma the actual manufacturer of Silodosin API, or a trading company?
Chemox Pharma manufactures Silodosin API directly at its own WHO-GMP certified facility in Dahej, Gujarat, in both IH and JP grades.
Q: What makes Silodosin different from other alpha-blockers like Tamsulosin?
Silodosin’s high selectivity for the alpha-1A adrenergic receptor subtype gives it a more favorable side-effect profile, particularly reduced dizziness and orthostatic hypotension, compared to less selective alpha-blockers.
