What are APIs (Active Pharmaceutical Ingredients)?

 

Probably the first thing that comes to your mind when talking about the pharmaceutical industry are companies that produce medicines. All over the globe, there are lots of companies that produce medicines. From big pharma companies such as Novartis, Pfizer, and Johnson & Johnson to local pharmacies, which are, in some cases, able to make medicines on patient level. And, of course, everything in between. 

All these medicine makers need APIs to produce medicines.

But, what are APIs?


People take medicines to cure, diagnose, treat, or prevent a disease. Most medication contains a couple of ingredients. The most important one is the API, which stands for Active Pharmaceutical Ingredient. This is the actual substance in the medicine that has to do the work in your body. 

For example, the API in Aspirin is Acetyl salicylic acid. This API will try to fight the pain of your fever or headache. Some medicines carry the name of the API. For instance, the API of Paracetamol is Paracetamol. To make a pill, you'll need more ingredients than just the API. That's where excipients come in. These ingredients are used to give the pill, for example, volume, a sweet flavor, or a color.

The term API is not only used in the pharmaceutical industry, but also web developers are speaking about an API, Application Programming Interface. So, make sure you're not joining the wrong forum or hiring the wrong specialist;).
 

How and where are APIs made?
The API market alone is already a multi-billion dollar market. APIs are mainly produced in large production plants. It's a complex chemical process of several steps. It's made from starting materials which can be a raw material or intermediate. Back in the days, pharma companies made and formulated the API and medicine in their home countries.

Over the past few decades, many companies have outsourced their API manufacturing process to Asia to cut costs. Today, India and China are the largest API producing countries. Some of the largest suppliers are Aurobindo, Dr. Reddy’s, Cipla and SUN pharma. They are all founded, or based in India. But, since most starting materials are made in China, we can call China the API pharmacy of the world.

APIs are most often made in a powder form and then sold in large quantities to drug manufacturers. 


Quality of APIs (active pharmaceutical ingredients)
Medication is, of course, intended to help people. So, we need to know the ingredients such as the API are safe to use.

No matter where an API is produced, it has to meet the safety and quality criteria of the country where end users are located. That means, drugs sold in the EU need to meet the strict safety and quality standards of the European Medicines Agency and those sold in the US need to meet the regulations issued by the U.S. Food and Drug Administration (FDA).

Companies in the entire API supply chain get inspected by their local government. They could also be inspected by foreign government instances and third party companies do audits at each other companies.

When everything is up to code companies are given a certain certificate, such as GMP or a written confirmation, so other professionals in the industry know that thát company complies with the industry standards without them having to inspect or audit themselves. When the inspection fails, the companies will be issued a warning and pharmaceutical buyers won’t be able to buy there until the issues are resolved and the company is re-inspected.

Not only the factory or production facility is inspected, every batch of produced API is also analysed by laboratories, depending on the situation it is even possible that one specific batch is analysed multiple times: For example, by the company that produced it, by a 3rd party laboratory, by the trader who buys it, and by the hospital that will use it.


The difference between QA/QC
Also, every pharmaceutical company has an entire team dedicated to quality assurance and quality control. This team can consist out of pharmacists, chemists, biologists and other personnel that is trained to be a qualified person. You could say that the first team, quality assurance, makes sure everything is fine before the production process even starts, whilst the quality control checks if everything was performed according to plan. 
 

Nonproprietary names- USAN/INN

While the number of available prescription or over the counter drugs under different names increases daily, the situation is a bit different in case of APIs. Having in mind how expensive the steps to introducing a new drug to the market are, APIs do not show up as fast. Also, there is a rigorous rule on the market of APIs- one API is sold under only one name- a nonproprietary name.

To avoid a dangerous confusion on this market, WHO in cooperation with national drug safety agencies from all over the world came up with a list of nonproprietary names back in 1953. The organization revises the list regularly and you can send them a request for a new International Nonproprietary Names (INN).

So, everywhere in the world, Ramipril is sold as Ramipril, and that API can’t be bought under any other name.

Drug manufacturers can sell their drugs under any name they want, but they need to put the API name right under the brand name.
