APIs vs Excipients: Understanding Pharmaceutical Raw Materials in Nigeria

The pharmaceutical raw materials industry in Nigeria is one of the most vital sectors for public health and economic growth. With over 200 registered pharma companies including Emzor, Fidson, Dana, GSK, and Greenlife, the industry plays a critical role in producing essential medicines for a population of more than 220 million people.

But at the heart of drug manufacturing are two key categories of raw materials: APIs (Active Pharmaceutical Ingredients) and Excipients.

While APIs are the compounds that deliver the therapeutic effect, excipients serve as the medium, stabilizer, or enhancer that makes the drug safe, effective, and easy to administer. In this article, we break down the difference, showcase examples relevant to Nigeria’s market, and explain how platforms like Matta make sourcing easier.

What Are Active Pharmaceutical Ingredients (APIs)?

APIs are the biologically active components of a drug responsible for producing the intended therapeutic effect. Without APIs, medicines would not function.

Examples of APIs in Nigeria:

Paracetamol Powder – Widely used for pain and fever relief.
🔗 Paracetamol API Suppliers
Aspirin Crystals (Acetylsalicylic Acid) – Used as a pain reliever and anti-inflammatory.
🔗 Aspirin API Suppliers
Metronidazole – Essential for treating bacterial and protozoal infections.
🔗 Metronidazole API Suppliers
Methyl Salicylate – Used in topical pain relief ointments.
🔗 Methyl Salicylate Suppliers
Magnesium Carbonate – Often used as an antacid and stabilizer in drug formulations.
🔗 Magnesium Carbonate Suppliers

Why APIs Are Critical in Nigeria:

Nigeria still imports over 70% of its APIs, mainly from India and China (BusinessDay Nigeria).
Local API manufacturing is minimal, making sourcing reliability a top challenge.
APIs determine drug cost and availability, directly affecting public health.

What Are Excipients?

Excipients are the inactive substances in a drug formulation. They act as carriers, binders, stabilizers, or flavoring agents that make medicines safe and easy to consume.

Examples of Excipients in Nigeria:

Corn Starch – Used as a disintegrant in tablets.
🔗 Corn Starch Suppliers
Lactose Monohydrate – Common filler in tablets and capsules.
🔗 Lactose Suppliers
Sucrose – Adds sweetness to syrups and chew-able tablets.
🔗 Sucrose Suppliers
Sorbitol – Used in sugar-free syrups and chewables.
🔗 Sorbitol Suppliers
Caramel Color – Adds color to syrups and liquid medicines.
🔗 Caramel Color Suppliers
Aspartame – Artificial sweetener for sugar-free formulations.
🔗 Aspartame Suppliers
Ascorbic Acid (Vitamin C) – Functions as antioxidant and excipient in certain formulations.
🔗 Ascorbic Acid Suppliers

Why Excipients Are Critical in Nigeria:

Improve drug stability in Nigeria’s hot, humid climate.
Ensure tablet binding and disintegration in solid dosage forms.
Enhance taste and patient compliance, especially in pediatric medicines.

Table: APIs vs Excipients

Aspect	APIs	Excipients
Function	Provide therapeutic effect	Vehicle, stabilizer, flavor, binder
Examples	Paracetamol, Aspirin, Metronidazole	Lactose, Starch, Sorbitol, Caramel Color
Cost Impact	Major driver of drug price	Smaller share of cost
Regulatory Status	Heavily regulated (NAFDAC, WHO GMP)	Must comply with pharmacopoeia standards
Sourcing Challenge	Mostly imported (India/China)	Widely available but require quality checks

Regulatory & Compliance in Pharma Raw Materials

NAFDAC (National Agency for Food and Drug Administration and Control) regulates APIs and excipients used in Nigeria.
WHO Good Manufacturing Practices (GMP) guidelines must be followed.
Excipients also need to meet pharmacopeia standards (e.g., USP, BP, Ph. Eur.).

Failing to source from verified suppliers can lead to drug recalls, regulatory penalties, and loss of consumer trust.

The State of Pharma Raw Material Supply in Nigeria

Nigeria’s pharma sector faces key challenges:

Import dependency: Over 70% of APIs are imported.
FX fluctuations: Rising dollar-naira exchange rate inflates production cost.
Local production gap: Limited capacity for excipient manufacturing (like starch and lactose).
Logistics bottlenecks: Port delays increase lead times for imports.

Platforms like Matta bridge this gap by connecting manufacturers to verified suppliers with clear documentation and competitive sourcing options.

H2: The Future of APIs & Excipients in Nigeria

Local API Production: There’s strong government push for backward integration and local API manufacturing under Nigeria’s Pharma Transformation Agenda.
Natural Excipients: Increasing research into natural binders like cassava starch as alternatives to imported starch.
AfCFTA Expansion: Nigerian pharma companies are preparing to export medicines regionally, increasing raw material demand.
Digital Marketplaces: Platforms like Matta are becoming central to sourcing strategies for both SMEs and multinationals.
