Introduction of API

2020-07-16


About API


API,short for Active Pharmaceutical Ingredient.It means the active ingredient which is contained in medicine. For example, an active ingredient to relieve pain is included in a painkiller. This is called API. A small amount of the active ingredient has an effect, so only a tiny part of the active ingredient is contained in medicine. You will find the name and amount of the active ingredient contained in the medicine on the package of OTC (over-the-counter) drugs.



Who makes APIs


First of all, as an API manufacturer we think of how to make a chemical compound which becomes an API in the laboratory. We also have to consider the degree of concentration and which temperature allows a high quality of API to be manufactured efficiently. In order to find answers to these questions, our staff in the development department set about conducting a series of experiments. Once they have decided how to make the compound, our staff in the production department manufacture a high quantity of APIs using the large pharmaceutical reaction reactors in our plant. Our quality control staff then conducts analyses in the testing laboratory to examine whether the pharmaceutical API manufactured is ultrapure. After testing, our quality assurance staff confirms that everything has been performed correctly in accordance with GMP from manufacturing of API to quality testing. As you can see, a considerable number of staff is involved in the production phase until an API is finally manufactured.


How APIs are made


API and raw material are often confused due to the similar usage of the two terms. What is the difference? Raw material refers to chemical compounds that are used as a base to make an API. We purchase the raw materials from raw material or chemical product manufacturers internationally. When using the raw materials, as an API manufacturer we produce API in the large reactor in our plant. The API is not made by only one reaction from the raw materials but rather it becomes an API via several chemical compounds. The chemical compound which is in the process of becoming an API from a raw material is called an intermediate. Among the APIs we produce, there is an API which passes through over ten kinds of intermediates in a process when it changes from being a raw material into an API. After this long manufacturing process, it is purified until it reaches a very high degree of purity and finally becomes an API.



From API to patient


We manufacture APIs and drug manufacturers make medicines from APIs. In addition to APIs, a variety of pharmaceutical excipients are contained in the medicine. Drug manufacturers make medicines by mixing APIs and pharmaceutical excipients. This is how an API becomes a medicine. It is delivered to hospitals and equipment in pharmaceutical industry until it reaches the patient. If an API is not ultrapure, a medicine cannot meet the strict quality criteria so the quality of an API plays a very important role.
