Role of Automation In Pharmaceutical Manufacturing Industry

Automation is the process of replacing human workers in a production process with machines and equipment to carry out both mental and physical tasks1–7. Pharmaceutical automation refers to the mechanical processes used in producing, packing formulations, delivering pharmaceuticals, and handling materials. Organizations discovered how crucial it is to safeguard the accuracy of data produced and that, in a controlled setting, process irregularities had to be looked into and eliminated. The March 2017 micro therapeutic research lab incident brought to light the need for pharmaceutical companies to make sure that all of their data, including data created by third parties, complies with industry laws.Automation, which is self-dedicated, is the use of a computer or other control system to operate industrial machines and processes while minimizing human interference.The demand for human sensors and mental processes is significantly reduced by automation. Processes and systems can also be automated. (1)

AI, automation, and robotics technologies are revolutionizing the pharmaceutical industry. A vital component of the rapidly expanding global healthcare ecosystem are pharmaceutical businesses. However, the pursuit of tailored medications, productivity goals, and growing healthcare expenses are putting more and more strain on it. Conventional approaches to medication development, production, and distribution are labor-intensive, time-consuming, and costly. Artificial Intelligence (AI) paired with automation and robots create a completely new approach of coping with these old difficulties. AI expedites drug development by utilizing the most sophisticated data processing and analytic tools, machine learning, and forecast models. It improves clinical trial designs and establishes new therapeutic performance benchmarks. Automation has decreased repetitive labor, improved consistency, and decreased human error in pharmaceutical manufacturing, resulting in more dependable, superior, and effective goods. Production processes have been transformed by robotics, many of which are AI-driven and have increased precision and capacity. These developments concerning the needs of global health can be advantageous to the pharmaceutical business. They are essential to improving supply chain systems, upholding various levels of regulatory compliance, and developing tailored healthcare solutions. The further advancement of these technologies will present previously unheard-of chances to improve pharmaceutical operations' efficiency, safety, and speed. They might also usher in a new era of therapeutic approaches with cutting-edge treatments. The usage of AI in the pharmaceutical sector has grown over the past several years and is predicted to continue to do so. (2)

What is automation and how it is used in Pharmaceutical Industries

Automation is the use of machines to execute the majority of repeatable and crucial tasks in the pharmaceutical industry, such as carrying out mental and physical tasks in a production process that would otherwise require human labor16–24. The industries have been growing faster, and the pharmaceutical sector is no exception. The regulations are becoming more stringent than they were previously. In fact, time can be saved by introducing automation into enterprises. Industrial management can adapt to the constantly shifting regulatory limitations with the use of automated functions. The requirement for human sensors is significantly decreased by automation. For many years, many companies all around the world have been using newer technology to replace human labour for a variety of purposes. Since the newest technology can always have a significant impact on job chances in industries, certain worker unions and other communities have long opposed this practice due to human replacement. Automation is a collection of technologies that enable machines and systems to operate with less human intervention and achieve better performance than manual operation. Computer vision systems have been used for quality assurance purposes much more frequently lately. As a result, the systems may eventually take the position of human inspectors. Both computer hardware and software have advanced.

Claims management is one important area where automation is quite beneficial. Pharmaceutical firms can greatly reduce human error while maintaining regulatory compliance by automating payment, insurance, and claims handling procedures. Additionally, pharmaceutical businesses can automate every step of the claim management process, including tracking claims from submission to settlement, maintaining documentation, confirming patient eligibility, and guaranteeing prompt reimbursements. In addition to streamlining the process, automation makes it possible to track and monitor the status of claims, which reduces administrative expenses and improves customer satisfaction. In the end, automating claim handling helps pharmaceutical companies improve operational effectiveness, lower error rates, and improve revenue cycles. AI has already started to be used in pharmaceutical manufacturing. Examples include the use of machine vision technology to replace human visual inspection of vials, caps, and packaging; predictive equipment maintenance to lower risks, disruptions, and production downtime; and automated quality control, which enables smooth scheduling of analytical testing and continuous process quality assurance. (5)

Drivers for Automation and Paperless Systems:

1          Data Integrity and ALCOA+ Principles:

In order to guarantee that all data generated in the pharmaceutical sector is accurate, consistent, comprehensive, and dependable throughout their existence, data integrity is essential. In the end, preserving data integrity protects patient safety, product quality, and regulatory compliance by facilitating wise decision-making in R&D, production, and distribution. To maintain data integrity standards, regulatory bodies including the FDA, MHRA, EMA, and WHO have set stringent rules under GMP, GCP, and GLP. Guidelines for keeping verified, safe, and traceable electronic records and systems are provided by frameworks such as ISPE GAMP 5 and FDA 21 CFR Part 11. Adherence to ALCOA and ALCOA+ principles—which guarantee that data are Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, and Available—is crucial for preserving dependability and compliance in all pharmaceutical activities, despite ongoing difficulties (6).

2          FDA’s Emphasis on 21 CFR Part 11 Compliance:

In order to maintain reliable, secure, and auditable systems, the U.S. FDA's 21 CFR Part 11 regulation highlights the significance of electronic records and electronic signatures. To satisfy these compliance standards, Manufacturing Execution Systems (MES) like Siemens Opcenter and Rockwell FactoryTalk PharmaSuite include specific modules. Strong data security features including encryption and access controls, user authentication using unique credentials, and secure electronic signatures (single or double authentication depending on process criticality) are all made possible by these modules. Validation procedures guarantee that systems are dependable and compliant with Good Automated Manufacturing Practice (GAMP 5) criteria. For instance, Siemens Opcenter's quality management system facilitates ongoing regulatory alignment, while Rockwell's eBR module automates compliance documentation.

These solutions promote data integrity and compliance by automating data gathering, guaranteeing safe audit trails, and fostering interoperability. They also improve efficiency, decrease downtime, and make regulatory inspections in GMP-regulated environments easier. (6).

Machine Vision System: Industry 4.0

Has enabled flexible and tailored mass production with cutting-edge technologies, ushering in an era of automated manufacturing.This change has led to the replacement of traditional manufacturing techniques with intelligent systems, in which machines are able to perform tasks like self-awareness, self-prediction, self-comparison, self-configuration, self-maintenance, self-organization, and resilience.These systems are capable of independent operation, decision-making, and continual learning.Falling costs of sensors and connectivity have led to a dramatic surge in industrial devices connected to the Internet. A key component of Industry 4.0 is this interconnectedness, which makes it possible to gather enormous volumes of data, most of which is wasted because it is not interpreted or analyzed. This data can improve production line automation, maximize equipment health, increase efficiency, and enable defect-free manufacturing when used and analyzed in real time.

Quality control in manufacturing guarantees that goods are defect-free and satisfy client demands. Inadequate execution can endanger customers and damage a business's reputation. Product quality can be jeopardized by even minute variations in the manufacturing process that are imperceptible to the human eye. Although product inspection prior to shipment is an important preventive precaution, manual inspection is slow, restricts production productivity, has low scalability, and necessitates a substantial amount of training time for qualified inspectors. Additionally, human performance frequently deteriorates throughout extended shifts. On the other hand, machine vision, a subfield of artificial intelligence, makes it possible to inspect all products quickly and in large quantities, especially when paired with machine learning algorithms for picture recognition.By examining production data in real time, machine learning may potentially do more than just identify errors; it can also pinpoint their underlying causes. By offering an optimized machine vision system design that combines fault detection with continuous process improvement, this study advances this discipline. The system meets Industry 4.0's goal of harnessing connected device data to develop faster, more flexible, and more efficient processes that deliver higher-quality products at lower costs by identifying the ideal process variables to accomplish defect-free manufacturing.The structure of the paper is as follows: Section 2 examines current research and relevant literature; The technologies used in the suggested model are described in Section 3; The comprehensive system scenario is shown in Section 4. The IoT architecture is described in Section 5, and the experimental findings and their analysis are shown in Sections 6 and 7. (7)

Numerous medical gadgets and implants are assembled and packaged by robots. Additionally, hospitals and mail-order pharmacies use robotics to fill prescriptions.

PillPick is a pharmacy automation technology that helps hospitals increase patient safety by removing the possibility of drug errors during packaging and distribution. Bar coding, packaging, storing, and dispensing unit dose pharmaceuticals all require fewer human touches thanks to PillPick. Packaging and dispensing systems increase hospital pharmacy operations' accuracy and efficiency by automating these processes. Future Scope: AI, automation, and robotics in pharmaceuticals have a broad and revolutionary future that might alter many facets of drug research, manufacturing, and healthcare solutions. The areas with enormous potential and growth are listed below: Artificial intelligence-powered drug discovery and development: This sector will continue to evolve and advance more quickly as AI assists in the analysis of large biological datasets, predicts how medications will interact, and finds new biological compounds even more effectively. With machine learning on its side, it is hoped that AI can expedite the creation of novel and targeted treatments and vaccinations, possibly cutting the time it takes to develop new drugs by years.

More treatments that take into account the genetic and environmental characteristics of the patient will arise from the expansion of AI's role in biomarker identification and customized medicine. By doing this, treatment efficacy will be increased and adverse responses will be decreased. AI and Automation for Better Clinical Trials: AI will be crucial for patient recruitment and clinical trial design, optimization, and monitoring.

6m classification & identification of CCPS in an aseptic environment

The 6M Technique promotes continuous improvement in the production environment by assisting in the identification of process inefficiencies (5-7). CCPs for general aseptic operations discuss the scope of 6M. We have included parts in this study that specifically address situations that require special attention to testing and controls, such as powder injectables and large-volume parenteral (LVPs).

1 .Facility

Controls for a clean roomEvery point of intersection where garbage, people, and materials pass through is a source of worry. There is a lot of information available regarding the facilities requirements for aseptic operations. Prior to their intended usage, facilities are qualified. To find the CCPs, equipment qualifications, simulation studies, and validations are frequently carried out. Notably, the design needs to guarantee that there are no recesses that cannot be cleaned. The Grade A/B process spaces are not equipped with sinks or drains. Every other drain has its flora microbiologically monitored. To avoid contamination, modern building designs included distinct passageways for RM and FG movements as well as designated corridors for trash flow.

A crucial CCP is a positive pressure vari-ancevariation with the environment. Therefore, it is customary to maintain a pressure differential of at least 15 pascals between two different classified zones (regulation requires NLT 12 pascals) and at least 6 pascals (regulation requires NLT 4 pascals) between two rooms with the same classification (regulation requires NLT 4 pascals). To improve monitoring capabilities, calibrated magnehelic gauges that can record and sound warnings are frequently installed.) is routinely upheld. Calibrated magnehelic gauges capable of recording and generating alarms are often plac

All the Cleanrooms are qualified and classified based on applications. Grade A (Filling area, sterile laundry receipt, LAFs area, Mobile LAFs, sampling area for pre-sterilized components), Grade B (filtration area, Receipt area for filtered liquid, blending area of sterile APIs, receipt area of filtered liquid, blending area for sterile APIs, peripheral area of filling), Grade C (laundry washing, Compounding area, equipment washing area, secondary change rooms, unloading pre-sterilized components, handling pre-sterilized components) and Grade D (Primary change room, equipment washing area, vial washing area, plug washing area) areas are equipped with terminal HEPA (H14) (12-21). CNC areas (Vial inspection, Packaging and labelling, RM stores, Microbiology waste disposal area, Quality unit, Finished Goods store) are equipped with 5µ filtered air. Lux level in the vial inspection area is a CCP and shall range from 2000 – 3750 lux depending on operation. (10)

2.         Men

Training, gowning qualification, health & hygiene Human activity in the cleanrooms is the primary reason for particulate and microbial contamination. CCPs such as routine self-inspection, materials for apparels, garment sterilization, maintenance and the overall gowning processes are critical. Standards for cleanroom garments are described and their quality can be assessed using various procedures . The Helmke Drum test that verifies the particle shedding, especially when a garment is washed multiple times, is critical. The number of wash cycles for garments is hence validated. Sterilized garments shall have a definite validity period and the sterility assurance level shall be NLT 10-6 after sterilization Gowning qualification tests the operator’s proficiency to don and doff the garments correctly and conduct EM in Grade B areas. Re-qualification criterion, other than the annual frequency, is also required. Companies use a risk-based approach to determine the places for sampling because no specific swab sample locations were documented in the literature (10).

3.         Machinery (equipment, utilities & tools)

Since process equipment, utilities, and spare parts are situated in the Grade A area, control over their use and upkeep is crucial. Before the activity begins, a line clearance operation is carried out to enlist the various CCPs. For traceability purposes, the operation's handling of tools, utilities, and machinery is captured on video.

Process equipment & utilities

Automation enhanced data integrity and decreased human interference. To avoid contamination, the utmost level of automation is enabled on all approved process equipment. GAMP recommendations and 21 CFR Part 11 must be followed by equipment with data loggers and PLCs that can record and generate alarms in real time (27). Filter membranes must adhere to ISO 16610-21 (31). The majority of qualified utilities are filtered through 0.2µ porosity filters after coming into contact with the product solutions. A list of CCPs for different essential utilities is provided. The input material for WFI generation is purified water, and its quality is constantly assessed. Variable frequency drives were used in the most recent water purification systems to achieve the required flow velocity (NLT 1.3 mt/sec). When the operating restrictions are exceeded, the most recent technology is built to send SMS alerts to the relevant staff. Also, hooter alarms are equipped to alert the engineering personnel if there is a deviation in the set point conditions.

Tools & Spares management

In order to preserve sterility, all instruments brought into core regions are sterilized and kept there. Don't pick up and use any sterile tools or equipment that unintentionally falls on the ground. Rather, make sure the room has more sterile supplies. In order to maintain strict environmental cleanliness standards, all gloves and tools are made for a single usage and then thrown away. Sterilized glove ports are used in procedures to prevent contamination. To ensure their appropriateness for usage, latex gloves that have been pre-sterilized using either gamma or ethylene oxide are tested for sterility in batches. In order to avoid particulate contamination, these gloves are also powder-free.(10).

4.         Materials and Methods Receipt of raw materials (RM)

Only authorized sellers may get RMs. Sterility tests are performed on pre-shipment samples of sterile APIs, rubber stoppers, and other gamma-sterilized materials, such as sterile PPEs. The order quantity is asked to be released from the supplier's location once the sterility has been confirmed. Once received, it is checked against an internal checklist. After being received, thermosensitive items must be properly packed with a temperature datalogger and stored under specified storage circumstances.

Sampling & dispensing

While excipients are sampled using (Square root of N + 1), non-sterile APIs are subjected to 100% sampling (9). AQL sampling techniques can be used for large receipts (33). The results of the pre-shipment sample are considered definitive for approving the batch, and sampling for sterile APIs is prohibited. Separate procedural controls are needed for buffers, antioxidants, and preservatives that are meant to be powdered for reconstitution (see discussion under CCPs for Powder injectables). Only after a satisfactory visual assessment with appropriate and specialized equipment may sampling be carried out. The sample instruments will also be subject to Current Trends in Biotechnology and Pharmacology investigations. For dispensing, reverse LAF systems that meet ISO 5 or Grade A/B standards are utilized.

Before beginning the activity, line clearance is confirmed. In-process material controls

Until manufacturing is finished, in-process materials must only be prepared in the Grade B area. To examine the impact of any unanticipated interventions during the process, hold time studies for solutions are conducted. At the conclusion of the hold period, the quality metrics must be similar to those of the final product.

Storage & despatch of finished goods

Finished goods (FGs) must be kept in a regulated environment with sufficient light and heat protection. The first-expiry-first-out methodology must be used in dispatch procedures, and the quantity reconciliation must be easily accessible. Each batch's retention samples must be kept in certain locations under physical lock and key so that any complaints or questions that may come up after dispatch can be looked into. For batch samples of finished goods, the retention period is one year longer than the specified shelf life. The specified shelf life for RMs is six months from the date of receipt. The entire contamination control strategy is largely unaffected by the storage and transportation of undamaged sealed containers.(10).

5.         Methods (Processes & simulations)

Regular unit operations and process qualification. Finding CPPs that have trouble continuously meeting the CQAs over the course of the product life cycle will be part of the process qualification. Procedural controls should ideally be created. The process's CCPs are recognized and recorded. The batch size for viscous solutions is frequently limited by the compatibility, integrity, adsorbent qualities, and filtration time of filter membranes.

Aseptic process simulation (APS)

The products made by aseptic filling are highly risky, in contrast to terminal sterilization, where parametric release of materials is allowed. Only aseptically filled items are eligible for media fill studies (APS). In media fill studies, media are prepared and filled into containers as if the product were created, rather than the product itself being manufactured. The procedure goes over every step required for a certain product. Media fill studies must include all unit operations related to the product's manufacture. To make that the product can tolerate any unintentional contamination, this must be carried out under stressful circumstances. The entire task must be completed as if it were a standard procedure, without being staged to take extra safety precautions. This could result in a false negative. The Parenteral Drug Association gave advice on how many containers should be used for the media fill research. Failures in the APS are not permitted by the industry. Any failure necessitates a comprehensive investigation, identification of the organism—at least down to the genus level—as well as its source and remediation to stop it from happening again.(10).

6)Measurement (routine controls and monitoring)

Sterility assurance:

The degree of certainty that a particular product or unit that is advertised as sterile actually satisfies the requirements of sterility is known as sterility assurance. There are multiple restrictions over practices, utilities, and the environment, and the test is damaging. Sterility assurance is aided by controls over the components outlined in the 6M environment as well as other factors like lowering or doing away with interventions, putting in place a closed, restricted access barrier system (RABS), and conducting sufficient process simulations that incorporate preventive testing and recurring vendor qualifications.(10).

Cleaning the dispenser

The dispenser is cleaned in three stages using automated processes. The apparatus is initially sterilized with ethanol (Clean 1) after the residual activity has been eliminated (Rinse).

Lastly, cleaning with water once more eliminates the ethanol (Clean 2). Ethanol should be used to rinse the connection line between the synthesizer and dispenser each day. The leftover ethanol should then be eliminated by drying the line with helium and rinsing it with water for injection. The synthesizer needs to be ready to receive the water and ethanol for this process.

(11)
