Bulk Active Pharmaceutical Ingredient (API) Sources for NULYTELY

Last updated: July 30, 2025

Introduction

NULYTELY (polyethylene glycol 3350, sodium chloride, sodium bicarbonate, and potassium chloride) is a widely used osmotic laxative primarily indicated for bowel cleansing prior to colonoscopy procedures. Its efficacy hinges on the quality and reliability of its active pharmaceutical ingredients (APIs). Securing diverse, high-quality bulk API sources ensures consistent production, regulatory compliance, and cost-effectiveness. This report explores key API sources, manufacturing trends, and strategic considerations pertinent to NULYTELY production.

Overview of APIs in NULYTELY

The formulation of NULYTELY mainly involves four APIs:

• Polyethylene glycol 3350 (PEG 3350)
• Sodium chloride
• Sodium bicarbonate
• Potassium chloride

Each API's sourcing intricacies influence manufacturing, regulatory approval, and supply chain stability.

Polyethylene Glycol (PEG) 3350

Global Manufacturing Landscape

PEG 3350 is the principal active, and its sourcing is dominated by a handful of specialized chemical manufacturers. It is produced via ethoxylation of ethylene glycol, with processes requiring stringent control to ensure molecular weight consistency.

Major API Suppliers

1. Dow Chemical / DowDuPont
   As a leading supplier, Dow supplies pharmaceutical-grade PEG 3350, backed by rigorous quality controls and global distribution networks. Their established manufacturing facilities in the USA and Europe ensure robust supply.

2. BASF
   BASF’s portfolio includes high-purity PEGs, including PEG 3350, with facilities in Europe and Asia. Their products meet pharmacopoeial standards suitable for API use.

3. Lotte Chemical
   A major Asian producer, Lotte provides PEG of pharmaceutical grade, with expanding manufacturing capacity aimed at East Asian markets.

4. Sinopec
   One of China's largest chemical producers, Sinopec supplies PEG 3350 with competitive pricing, though regulatory validation remains critical for global distribution.

5. Dow Corning / Dow Chemical
   With longstanding expertise, these firms produce PEG 3350 for both medical and industrial applications, maintaining high manufacturing standards.

Regulatory and Quality Considerations

API suppliers must comply with cGMP (current Good Manufacturing Practices) and meet pharmacopoeial standards, including USP, EP, or JP monographs. Suppliers’ ISO certifications, batch consistency, and traceability are critical criteria.

Sodium Chloride

Sources and Suppliers

Sodium chloride for pharmaceutical applications is predominantly sourced from:

• VWR International
• Thermo Fisher Scientific
• Fisher Chemical
• Local European and US chemical producers
  These suppliers provide pharmaceutical-grade sodium chloride (USP or EP grade), with sourcing from salt deposits (evaporated sea salt, rock salt) processed under strict quality controls.

Supply Considerations

• Purity Standards: Must meet USP or EP specifications, including low residual impurities.
• Bulk Availability: Usually supplied in bulk via tanker or bagged containers for pharmaceutical manufacturing.

---

Sodium Bicarbonate

Major Suppliers

• Tata Chemicals
• FMC Corporation
• Innophos
• Sodium bicarbonate producers in China and India

Companies that supply vaccine and pharmaceutical-grade sodium bicarbonate uphold strict quality controls, ensuring compliance with pharmacopoeial standards.

Regulatory Factors

Verification of certificate of analysis (COA), compliance with microbiological standards, and batch-to-batch consistency are necessary for API qualification.

---

Potassium Chloride

Leading Suppliers

• AkzoNobel
• Merck KGaA (EMD Millipore)
• BASF
• Local Asian manufacturers

The API must meet USP or EP specifications for injections or oral use, with an emphasis on low residual impurities and microbial limits.

Supply Chain and Quality Assurance

Ensuring API quality and supply chain resilience is paramount. Companies often establish multiple vendor relationships across regions to mitigate risks related to geopolitical issues, shipping disruptions, or regulatory changes. Due diligence, audits, and validation of supplier quality systems underpin sourcing strategies.

---

Regulatory and Compliant Sourcing

• GMP Certification: Mandatory for APIs used in systemic products like NULYTELY.
• Pharmacopoeial Compliance: USP, EP, JP specifications guide quality parameters.
• Batch Certification and Traceability: Essential for regulatory submission and audit readiness.
• Environmental and Sustainability Standards: Increasingly relevant; suppliers must adhere to environmental regulations and sustainability practices.

---

Strategic Considerations

• Cost Optimization: Balancing quality with manufacturing costs, especially in Asia.
• Capacity Planning: Securing multiple suppliers to avoid shortages.
• Regulatory Alignment: Continuous monitoring of changing standards.
• Supply Chain Security: Diversification and inventory management to mitigate geopolitical risks.

---
