Complete List of Commonly used Pharmaceutical API


Pharmaceutical API, or active pharma ingredients, is the core aspect of the pharma industry. Whether we need medicine for diabetes, heart failure, or even cancer, we need suitable and high-quality APIs. Regardless of the high manufacturing cost and strict policies, the market for API manufacturing has reached a great height. And why not?

Whether manufacturing the ongoing basic medicine or finding the drugs for pandemic situations, API or active pharma ingredients are involved at every stage of medicine development. But what exactly is API, its types, and the commonly used APIs in the pharma industry? Let’s explore answers to all such questions in our blog below!

What is Pharmaceutical API?

Pharmaceutical API or active pharma ingredients are the raw materials used to manufacture medicine for the disease. APIs are the active ingredients that produce the required effects on the human body. Sometimes, a common API is used with other APIs to form the required drug. 

The pharmaceutical API manufacturers combine several chemical compounds to create the required APIs. However, before becoming the API, those chemical compounds undergo a stage called intermediates. Those intermediates then form API after thorough testing and quality analysis. 

Types of Active Pharmaceutical Ingredients

Now that we know APIs’ basics let us quickly discuss their types. So, pharmaceutical APIs can be classified into two major categories, viz., synthetic and natural.

Synthetic APIs are also known as small molecules API. Around 66% of the pharmaceutical APIs available in the market today are synthetic APIs. On the other hand, natural pharmaceutical APIs are used for creating biologics. The trend of biologics has increased exponentially in recent times. However, they are still less in number when compared to synthetic APIs. 

Common Concerns of Outsourcing APIs

APIs are the essential components of medicine production. However, many companies fear outsourcing API manufacturing due to multiple reasons. The most common and biggest reason for them is the quality of API manufacturing.

Many active pharma ingredients manufacturing companies offer poor-quality APIs that, if used, can lead to inefficient medicines and fatalities. That’s why it is very important to outsource your API manufacturing to a reputed company having the required resources and knowledge.
