Rivaroxaban API Powder Quality Standards to Verify
Rivaroxaban API Powder Quality Standards to Verify
Pharmaceutical buyers and procurement managers sourcing Rivaroxaban API powder must evaluate critical quality standards such as identity confirmation, assay (purity), related substances, particle size, and heavy metal limits. With rising global demand for this anticoagulant and increasing dependence on Rivaroxaban API manufacturers in India, ensuring regulatory compliance, batch-to-batch consistency, and robust documentation becomes central to B2B procurement success.
This guide explains what to verify when sourcing from leading Rivaroxaban API suppliers in India, including Hyderabad-based WHO-GMP certified manufacturers such as Bio-Synth.
Why Rivaroxaban API Quality Standards Matter
Rivaroxaban API, a direct Factor Xa inhibitor, is widely used to prevent and treat blood clots. For B2B pharmaceutical buyers, ensuring API quality is essential for:
- Regulatory compliance
- Patient safety
- Consistent dissolution and bioavailability
- Smooth dossier submissions
- Successful scale-up from lab to commercial batches
With India emerging as a trusted global pharma export hub — and Hyderabad growing as a leading industrial zone — understanding these parameters becomes essential when purchasing from Rivaroxaban API manufacturers and CDMOs.
Key Quality Standards for Rivaroxaban API
Below are the must-check quality attributes before procuring from Rivaroxaban API suppliers.
1. Identity Confirmation (USP/EP Methods)
Why It Matters
Confirms you’re receiving the correct compound with no substitutions or mislabeling.
Tests to Request
- IR and UV spectra comparison
- Chromatographic profiling (HPLC / LC-MS)
- Specific Optical Rotation
- Molecular fingerprinting
These ensure compliance with USP and EP monographs — a critical aspect when dealing with Rivaroxaban API manufacturers in India.
2. Assay (Purity Percentage)
Why It Matters
Determines the exact active content. Imprecise purity leads to dosage inconsistencies in the finished product.
Typical Range
98% – 102% (anhydrous basis)
Factors Affecting Assay
- Synthesis route
- Residual solvents
- Crystallinity
Leading Rivaroxaban API manufacturers use validated HPLC assays to maintain compliance.
3. Particle Size Distribution (PSD)
Why It Matters
Impacts solubility, dissolution, and final bioavailability — making it a critical CQA.
Key PSD Parameters
- D10, D50, D90 (micron size distribution)
- NMT 10 µm for specific formulation needs
- Micronized/custom grades
Advanced Rivaroxaban API suppliers in India offer controlled PSD for formulation optimization.
4. Related Substances / Impurities
Why It Matters
Impurities may reduce efficacy or cause adverse effects. They are tightly regulated.
Limits
- Individual impurity: ≤ 0.1%
- Total impurities: ≤ 0.5%
Suppliers must provide complete impurity profiling, including:
- Residual solvents
- Synthesis intermediates
- Degradation impurities
5. Residual Solvents (ICH Q3C Compliance)
Why It Matters
Ensures solvent residues remain within safe limits after purification.
Common Solvent Limits
| Solvent | Class | Limit (ppm) |
| Acetone | 3 | 5000 |
| Acetonitrile | 2 | 410 |
| Toluene | 2 | 890 |
Class 1 solvents (e.g., benzene) must be undetectable.
6. Heavy Metal Limits (ICH Q3D)
Why It Matters
Heavy metals are toxic even at low concentrations.
Typical Limits
- Lead (Pb): <0.5 ppm
- Arsenic (As): <1.5 ppm
- Mercury (Hg): <0.1 ppm
WHO-GMP certified Rivaroxaban API manufacturers in India use ICP-MS/AAS analysis for accurate measurement.
7. Microbiological Quality
Although Rivaroxaban is a synthetic API, microbial limits must be controlled for oral formulations.
Allowed Limits
- Total aerobic count ≤ 1000 CFU/g
- Absence of E. coli, Salmonella
Top Rivaroxaban API suppliers implement stringent hygiene measures during manufacturing and packaging.
How Indian Rivaroxaban API Manufacturers Ensure Consistency
