Active Pharmaceutical Ingredient (API) and bulk active are also used in medicine, and the term active substance may be used for natural products. API, Active Pharmaceutical Ingredients are portions of any drug, which are active. Thus, depending on the drug’s administered dosage, the reactions and results differ. Certain drugs are comprised of more than one kind of API. Any drug is composed of two components. The first is the Active Pharmaceutical Ingredients, which is the central ingredient. The second is known as an excipient. This refers to the substance inside the drug or tablet. If it is in syrup form, then the excipient will be the liquid that has been used. Thus, excipients are the inactive or inert substances present inside a drug while the Active Pharmaceutical Ingredients is the chemically active substance, which is meant to produce the desired effect in the body. Certain Active Pharmaceutical Ingredients are unknown and hence require additional substances, which can work in conjunction with the API to produce the required medicinal effect.
