What is Pharma intermediates?
Pharmaceutical intermediates, or pharma intermediates, are compounds synthesized and used to produce active pharmaceutical ingredients (APIs). APIs are the biologically active components of a drug that have the intended effects. Pharma intermediates are chemical compounds that are used as precursors to make APIs.
Some key characteristics of pharma intermediates include:
- They are synthesized chemicals, not naturally occurring compounds.
- They are used as precursors to make active pharmaceutical ingredients.
- They are not intended to be biologically active or have a therapeutic effect. Their purpose is to be further chemically converted into APIs.
- They must meet high standards of purity and quality control since they are used to make ingredients for pharmaceutical drugs.
Difference between pharma intermediated and API
The main differences between pharma intermediates and active pharmaceutical ingredients (APIs) are:
• Pharma intermediates are compounds used to synthesize APIs. They are precursors or pre-stages to make APIs. APIs are the final biologically active ingredients of a drug.
• Pharma intermediates are not intended to have any biological activity or therapeutic effect. They simply act as building blocks to produce APIs. APIs directly provide the effects of a pharmaceutical drug.
• Pharma intermediates must meet high purity and quality standards to be suitable for making APIs. But they do not have to be as rigorously controlled and tested as APIs. APIs must meet strict specifications to be used in drugs for humans or animals.
• Pharma intermediates are usually not patented on their own, but companies may patent the process to make them or the final APIs they produce. APIs can be patented as new chemical entities to protect innovator drugs.
• The market for pharma intermediates, though large, is not as big as the market for APIs and final dosage form drugs. APIs and finished drugs generate more revenue.
Pharmaceutical Intermediates Market Size & Analysis
The pharmaceutical intermediates market is growing rapidly for several reasons:
• Increasing demand for patented drugs – There is a high demand for novel drugs to treat diseases. This requires complex multi-step synthesis routes which consume many pharmaceutical intermediates.
• Outsourcing API production – Many drug companies now outsource their API production to contract manufacturers in India and China. This has increased the volume of pharmaceutical intermediates traded worldwide.
• Growing generic drug market – The market relies on pharmaceutical intermediates to produce low-cost branded drug copies. This segment is growing fast due to patent expiries of blockbuster drugs.
Some key statistics on the pharmaceutical intermediates market:
• The global market is over $25 billion and is growing at around 6% annually.
• Asia Pacific, especially India and China, dominate the market with over 70% share due to low costs and government support.
• The top 5 players (Lonza, patent holder, Vertellus, etc.) control around 50-60% of the market.
• India’s market alone is over $10 billion, catering to domestic demand and exports. Major hubs are Hyderabad, Mumbai, Delhi, etc.
• Recent trends include use of continuous processing, green chemistry innovations, and import-export between regions to optimize costs and availability.
Key factors influencing growth include:
• Increasing investments in R&D by pharmaceutical companies to develop new drugs. This boosts demand for intermediates.
• Growing geriatric population and rising prevalence of chronic diseases drives the pharmaceutical market up.
• Government support for generic drugs and bulk drug manufacturing hubs in countries like India.
• Investments in China’s pharmaceutical sector as part of its “Made in China 2025” plan to reduce reliance on imports.
• increasingstringent regulations on environmental compliance and waste handling costs which raise manufacturing expenses.
• Emergence of novel drug discovery techniques like nanomedicine, biotech drugs, etc. requires specialized intermediates.
• Advancements in manufacturing technologies like continuous processing to improve efficiency, scalability and reduce costs.
What is the MOQ of the order?
Different products have different MOQ, for some MOQ is 100kg, for some is 1kg. you can contact with us for your detail requirements.
What is active pharmaceutical ingredient?
An active pharmaceutical ingredient or API is the biologically active component of a pharmaceutical drug. APIs are the ingredients responsible for the drug’s physiological or pharmacological action. In other words, APIs are the ingredients that make the drug work.
Some key points about APIs:
- APIs are derived from chemical synthesis, biotechnology, or natural sources. They must be highly purified and characterized.
- APIs require a drug master file describing the procedures and controls used for the API’s manufacture, processing, packaging, and storing.
- APIs must meet stringent regulations and quality standards to be suitable for pharmaceutical drugs for human or animal use.
Examples of pharmaceutical intermediates
Examples of pharma intermediates include ethambutol intermediate, clopidogrel intermediate, ezetimibe intermediate, etc. Common examples of APIs are acetaminophen, metformin, atorvastatin, etc.

• They have large manufacturing capacities, over 100-300 pharmaceutical intermediates and APIs. Some can produce over 500-1000.
• They follow GMP and FDA standards for manufacturing some intermediates and APIs. But the quality still trails western companies. Improving quality is a priority.
• They are highly price competitive due to low costs. This helps them grab market share from foreign players, especially for generic drugs.
• They are increasingly focusing on high-end innovative APIs and specialized niche intermediates not just bulk volumes. R&D spending is on the rise.
• Many are integrating horizontally into API production to gain control and reduce costs. Some are expanding globally through acquisitions.
• The government supports these companies through investments, subsidies, loose regulations, etc. as part of its pharmaceutical industry promotion plans.
