What is Pharmaceutical Manufacturing?
Pharmaceutical manufacturing is a specialized industry that designs and manufactures medicines as safely and efficiently as possible, and of the highest quality. It involves a highly detailed process, strictly regulated to transform raw materials into complete drug products that meet the requirements for safety, efficacy, and quality.
The organized and strictly regulated process has numerous steps to ensure that every batch of manufactured drugs achieves the required potency, purity, and quality for patients to use.
The pharmaceutical industry in India is one of the most critical industries in our country. The growth in India’s pharmaceutical industry, often referred to as the “pharmacy of the world,” is booming, going from $40 billion in 2021 to an estimated $130 billion by 2030, and predicted to rise to $450 billion by 2047
Pharmaceutical manufacturing in the healthcare supply chain ensures the supply of life-saving medications, from basic painkillers to complex biologics, to ensure hospitals, pharmacies, and clinical practices run smoothly.
The Pharmaceutical Manufacturing Process
Pharmaceutical production is a regulated and complex process that involves various critical steps to produce a good-quality, safe, and effective drug.
- Research and Development (R&D): Researchers will invent a new drug, assess its safety and efficacy through testing, and conduct early clinical studies on the product.
- Formulation: Scientists develop the drug’s structure in a formulation using an excipient-to-active-ingredient ratio that yields the desired therapeutic effect.
- Drying: Moisture is removed from the granular product to ensure stability and reduce degradation.
- Coating: Tablets and capsules are often coated with a protective layer to improve stability, regulate release rates, and boost patient adherence.
- Production: To ensure consistency and quality of medication in batch production, it must be produced in large quantities using established, documented procedures.
- Quality Control: Each batch undergoes a rigorous testing procedure to ensure its safety, efficacy, and quality.
- Packing and Distribution: Following this, the entire product is shipped to wholesalers, enabling pharmacies, hospitals, and other medical facilities in various markets to receive it in the correct dosage form.
Types of Pharmaceutical Manufacturing
Experts classify the categories in pharmaceutical manufacturing into several industries, which include the following aspects of drug manufacturing:
API (Active Pharmaceutical Ingredients) Manufacturing: Active Pharmaceutical Ingredients (APIs), the active ingredients in medications responsible for their biological benefits, are produced through fermentation, biological processes, or chemical synthesis. The crucial difference in any of these steps can significantly influence the outcome; therefore, consistency and precision are critical in the production of API.
Finished Dosage Form (FDF) Manufacturing: Finished Dosage Forms (FDF) such as tablets, capsules, injectables, and topical formulations. Finished dosage forms are the final consumable product given to patients. The FDF must undergo a series of intensive and methodical research, development, and manufacturing processes to reach the patient.
Biopharmaceuticals: Biopharmaceuticals, includes medicines made from protein, nucleic acids, or any living cells. Biopharmaceuticals are on the cutting edge of current experimental medication. Biopharmaceuticals focus on specific pathways in the body that have had a profound impact on potential treatment options, and they are evolving treatments to be more personalized and effective.
Contract Manufacturing (CMO/CDMO): In addition to production and development, Contract Development and Manufacturing Organizations (CDMOs) and Contract Manufacturing Organizations (CMOs) have made significant contributions to pharmaceutical companies’ development processes. The contributions of CDMOs and CMOs are substantial and play essential roles in ensuring that medicine is safely and on time delivered to the market.
Pharmaceutical companies can outsource their development and manufacture of medicines to CDMOs or CMOs, by reducing the time required to plan, develop, test, and manufacture of the drugs. CDMOs and CMOs are experts at navigating complex regulatory environments, ensuring their products meet international standards.
Applications of Pharmaceutical Manufacturing
The production of pharmaceuticals serves a variety of purposes that are critical to public health:
Over-the-Counter Drugs: Producing drugs that are safe to take over-the-counter (OTC) without a prescription is known as manufacturing. People typically use these medications to treat common conditions such as allergies, colds, and headaches. Manufacturers must meet strict quality criteria during the OTC medication production process to ensure the efficacy and safety of the products.
Prescription Medications: Doctors prescribe medications to treat more serious or long-term medical disorders that require their approval. These include cardiovascular drugs, antidepressants, and antibiotics. Manufacturers must meet strict safety and effectiveness requirements throughout the manufacturing process.
Export Pharmaceuticals: Essential pharmaceuticals are produced and distributed by pharmaceutical exporters. These treatments include immunizations that guard against infectious diseases as well as life-saving medications for chronic illnesses. Pharmaceutical exporters play a crucial role in the prevention and treatment of diseases worldwide by guaranteeing a consistent supply of these medications to areas with inadequate healthcare.
Vaccines and Biosimilars: Vaccines are among the most significant products of pharmaceutical production. Biological resources, including those derived from humans, plants, animals, bacteria, and other microorganisms, are utilized to produce biologics. These products are subjected to a strict, regulated production process and are frequently copyrighted. Biosimilars enter the market once their patents expire. Biosimilars imitate the active component in the reference biologic.
Regulatory Guidelines in Manufacturing
Compared to other sectors (e.g., food), the controls and processes that govern the manufacture of pharmaceuticals are much more stringent.
- Good Manufacturing Practices (GMPs) are a set of legally enforced standards that require any producer, processor, and packager of pharmaceuticals and medical devices to take measures to ensure that their products are effective, safe, and of high quality. GMPs cover every element of the manufacturing process, including raw materials, facility conditions, equipment usage, and the training and hygiene of personnel.
- The FDA, part of the U.S. Department of Health, oversees and enforces regulations related to food safety, tobacco, dietary supplements, prescription and OTC drugs, vaccines, biopharmaceuticals, blood products, medical devices, radiation-emitting products, cosmetics, and more.
- International public health is the focus of the World Health Organization (WHO), specialized agency of the United Nations (UN). Founded on April 7, 1948, with its main office in Geneva, Switzerland. The WHO is one of the member organizations within the United Nations Development Group.
- The Central Drug Standard Control Organization regulates India’s pharmaceutical industry. CDSCO regulates medicines, medical devices, cosmetics, food supplements, and veterinary products with a strong framework. CDSCO, under the Ministry of Health, Family, and Welfare, regulates pharmaceuticals under the Drugs and Cosmetics Act 1940 and Rules 1945. The regulatory framework requires high compliance and quality. To ensure safety, quality, and efficacy of the pharmaceutical product, regulatory rules are subject to frequent changes.
Regulatory authorities guarantee global market access and product safety through compliance. They conduct frequent audits to identify irregularities, and they may suspend licenses, impose fines, or issue recalls in cases of noncompliance.
Emerging Trends in Pharma Manufacturing
The technological evolution and environmental changes swirl around pharmaceutical manufacturing production.
- Artificial intelligence development is helping pharmaceutical manufacturing and patient identification by allowing pharmaceutical companies to automate and enhance the pharmaceutical process. It ultimately increases the efficiency of drug manufacturing while reducing waste and errors, thanks to recent advancements in artificial intelligence and machine learning.
