Pharmaceutical industry divided into two broad categories :

• Active Pharmaceutical Ingredient (API)

• Formulations

Active Pharmaceutical Ingredient (API):

- The active pharmaceutical ingredient (API) is the primary component of a medication that produces its therapeutic effects.

  - It's the chemical substance responsible for the intended physiological or pharmacological action in the body.

 

- Natural or Synthetic:

APIs can be derived from natural sources such as plants, animals, or microorganisms, or they can be synthesized in a laboratory.

  - Natural sources: For example, morphine, a pain-relieving API, is derived from the opium poppy plant.

  - Synthetic: Many APIs are created through chemical synthesis, where specific molecules are built from simpler starting materials in a controlled environment.

​

 - Purity and Potency:

APIs must meet strict standards of purity and potency to ensure safety and efficacy.

  Purity: This refers to the degree of absence of impurities or other substances in the API.

  Potency: Potency relates to the strength or concentration of the API needed to produce the desired therapeutic effect.

 

Dosage Forms:

APIs can be formulated into various dosage forms, including tablets, capsules, injectables, and topical creams.

  Tablets: APIs are compressed into solid form along with other excipients to create tablets that can be swallowed.

  Injectables: APIs are dissolved or suspended in a liquid form for administration via injection.

  Topical creams: APIs are combined with ingredients that facilitate application to the skin for localized effects.

 

Formulation:

- Formulation refers to the process of combining the API with other substances (excipients) to create a final dosage form suitable for administration.

- Excipients are inactive ingredients added to the formulation to improve stability, bioavailability, taste, appearance, or other characteristics of the medication.

 Excipients:

 Excipients serve various functions in the formulation:

 Binder: Holds the ingredients together in tablet or capsule form.

 Filler: Adds bulk to the formulation and ensures uniform distribution of the API.

 Disintegrant: Promotes the breakup of tablets or capsules in the digestive tract for absorption.

 Preservative: Prevents microbial growth and maintains stability during storage.

 Flavoring agents: Mask the taste of unpleasant APIs to improve patient adherence.

 

Packaging and Delivery:

 Formulations are packaged in containers designed to protect the medication from environmental factors such as light, moisture, and oxygen.

 Different delivery methods are used based on the dosage form and route of administration, such as oral, topical, injectable, or inhalation.

 

Regulatory Compliance:

 Formulations must adhere to regulatory requirements regarding safety, efficacy, quality, and labeling before they can be marketed.

 Regulatory agencies such as the FDA in the United States and the EMA in Europe review formulations to ensure compliance with stringent standards.

 

In summary, while the API is the active ingredient responsible for the therapeutic effect of a medication, formulation involves combining the API with excipients to create a safe, effective, and stable dosage form for administration.
