1. 1. AI in drug Discovery:

Drug discovery is being revolutionized by artificial intelligence (AI), [2] which speeds up the process of finding new drug candidates, improves lead compounds, and lowers the overall time and expense of research and development. Conventional drug development methods are time-consuming and labor-intensive, frequently involving years of trial and error and substantial financial outlays. AI-driven methods, especially deep learning (DL) and machine learning (ML), are changing this environment by making it possible to virtually screen possible therapeutic compounds, do predictive modeling, and analyze data quickly.[3]

1. 2. Personalized Medicine:

Precision medicine, another name for personalized medicine, uses artificial intelligence (AI) and sophisticated data analytics to customize medical care for each patient according to their lifestyle, genetics, and surroundings. Personalized medicine seeks to maximize therapeutic effectiveness while reducing side effects, in contrast to the conventional "one-size-fits-all" strategy. To determine the best treatment plans for every patient, AI-driven technologies such as machine learning and deep learning analyze enormous datasets including genomic sequencing, electronic medical records, and biomarker profiles.

1. 3. Disease diagnosis:

In several medical domains, artificial intelligence (AI) is transforming disease diagnosis by improving precision, effectiveness, and early detection. Human knowledge is frequently used in traditional diagnostic techniques, which can be laborious and error- prone. In order to provide more accurate and timely diagnoses, AI-powered technologies such as machine learning (ML), deep learning (DL), and natural language processing (NLP) evaluate enormous volumes of medical data, including imaging scans, test results, and electronic health records (EHRs).[4]

1. 4. Operational Optimization:

Through the simplification of processes, cost reduction, and productivity enhancement at all phases of drug discovery, production, and supply chain management, artificial intelligence (AI) is transforming operational efficiency in the pharmaceutical sector. Pharmaceutical firms may increase overall efficiency and optimize processes by utilizing data-driven decision-making, predictive analytics, and AI-driven automation.

How does AI works:

Developing an AI system entails meticulously imitating human traits and abilities in a machine and leveraging its processing capacity to surpass our abilities. A thorough understanding of AI is necessary to comprehend its various sub-domains and how they might be used in various industry sectors.

1. 1. 1. Machine learning (ML) is the process of teaching a computer to infer and decide on the basis of past information. In order to determine the relevance of these data points and reach a possible conclusion, it analyzes past data and looks for patterns without depending on human experience. Natural language processing (NLP) refers to the process by which a machine can read, understand, and interpret a language. Once a computer understands the user's intended message, it will respond correctly.
      2. Deep learning (DL): Deep learning is a machine learning approach. Deeper networks were trained by DL's revitalized neural network in the 2000s. It trains a machine to read inputs through layers in order to categorize, infer, and predict the result. For instance, by examining the intricate layers of activity vectors and determining the connection strengths that drive these vectors using knowledge of stochastic gradient, it aids in understanding the complex internal representation required to comprehend the challenging language or analyze the objects.
      3. Networks of neurons (NN) These systems function similarly to brain cells in humans. They are a collection of algorithms that capture the interaction between a large number of underlying factors, simulating how the human brain functions.
      4. Cognitive computing: Algorithms for cognitive computing try to replicate how the human brain works and produce the intended outcomes by evaluating text, audio, visuals, and other inputs in a manner similar to that of humans. Additionally, sign up for free AI application training.
      5. Computer vision: Computer vision algorithms try to understand an image by breaking it down and looking at different parts of the object. This helps the machine categorize and learn from a set of images, allowing it to generate better findings based on previous observations.

When an AI system is used to control operations like manufacturing or clinical trials, the effectiveness of long-term learning is frequently diminished after training. Despite the relatively recent adoption of Quality by Design (QbD) methodology, the pharmaceutical business has improved, and the most recent industry 4.0 [5] initiatives appear to depict a rapidly developing sector. It is therefore very likely that an early AI application will be implemented if it is created. Unlike other scientific disciplines, pharmaceutical sciences have the potential to delay the standardization and codification of data. Standardization and data collection are necessary for AI training to be successful in the former.

AI used:[6][7]

Here are a few instances of AI's application in data processing:

1. Search engine optimization and data searching to yield the most relevant results.
2. If-then logic chains that can execute a sequence of commands based on arguments.
3. Using pattern recognition to identify significant patterns in large data sets for novel insights
4. Predicting future outcomes with probabilistic models.

AI in health care:

1. Administration: To reduce human error and increase efficiency, AI systems are helping with routine administrative tasks. Transcriptions of medical notes using natural language processing (NLP) assist in organizing patient data for easier reading by physicians.
2. Telemedicine: In non-emergency situations, patients can get in touch with an AI system at a hospital to evaluate their symptoms, input their vital signs, and decide if they need medical help. Medical professionals' burden is reduced when they are only given the most critical cases.
3. Assisted diagnosis: Thanks to computer vision and convolution neural networks, artificial intelligence (AI) can now analyze MRI scans to search for tumors and other malignant growths at an exponentially faster rate than radiologists can, with a far smaller margin of error.
4. Robotic surgery: Robotic surgery can do surgeries consistently around the clock without experiencing fatigue and has a very narrow margin of error. Because of their high level of precision, they are less invasive than traditional procedures and can reduce the amount of time patients need to recuperate in the hospital.
5. Vital statistics monitoring: To determine how well a person is doing, their health must be continuously assessed. The use of wearable technology is growing, but the data is not easily available and requires analysis to yield meaningful insights. Because vital signs can predict changes in health before the patient is aware of them, several applications have the potential to save lives.

AI of next-generation 3D printed medicines:

AI and the pharmaceutical 3D printing (3DP) pipeline can collaborate. The traditional "one size fits all" approach to medicine needs to give way to the administration of customized drugs. Pharmaceutical 3DP [8] can provide personalized drugs in the clinic, but it currently requires the presence and expertise of certified 3DP professionals. None of the many common process optimization technologies, such as mechanistic modeling and finite element analysis (FEA), can fully optimize the many phases of pharmaceutical 3DP. On the other hand, machine learning can provide intelligent optimization at every stage of the production of 3DP pharmaceuticals. Eventually, this will remove the need for continuous expert input in the creation of 3DP [9] medications, lowering barriers to the clinical application of the technology.

Advantages and Disadvantages:[10][11]

AI's importance in the pharmaceutical industry, pharmaceutics, and drug delivery has increased as a result of current molecular commodities' longer production periods, higher costs, and decreased productivity. But even the creation of existing formulas is predicated on costly, time-consuming, and unpredictable research that is rife with errors. A new system called "computational pharmaceutics" is integrating big data, artificial intelligence, and multiscale modeling techniques into pharmaceutics, suggesting a substantial shift in the paradigm of medication delivery. [12][13][14] Over the past ten years, algorithms and processing power have grown exponentially, leading to the emergence of this system. Applying AI approaches to pharmaceutical product development includes tasks such as pre-formulation of physical and chemical properties, drug distribution, physical stability, in vitro-in vitro correlation, and activity prediction.

AI to predict new treatment:

AI advancements and a renewed interest in uncommon disease treatments. Currently, more than 350 million individuals worldwide suffer from more than 7000 rare diseases. Heal, a biotech business based in the United Kingdom, has secured $10 million in funding to develop new drugs for rare diseases. Another Swiss biotech company, Therachon, has received $60 million to develop drugs for rare genetic diseases.[15]

Adoption of AI by the pharma industry:

• Many pharmaceutical corporations connect with specialized companies and start-ups engaged in AI-powered drug discovery, either by cooperating with or purchasing tech companies and AI start-ups. [16][17] This allows them to use their expertise and resources to develop prospective therapy candidates based on established ideas and experience.
• Academic interaction: It is expected that business-academic relationships will grow as pharmaceutical companies begin to embrace AI. Enhancing internal knowledge and providing employees with the resources they require. Open scientific projects and research and development challenges: Compared to earlier methods, this practical AI adoption strategy for medicinal development carries a lower cost risk.

Challenges that pharma company’s face when attempting to adopt AI includes:

• AI is still viewed as a "black box"[18] by many pharmaceutical companies due to its novelty, youth, and esoteric nature.
• Because most IT programs and systems in use today were not developed or planned with artificial intelligence in mind, there is inadequate IT infrastructure. To make matters worse, pharmaceutical businesses have to spend a lot of money on upgrading their IT infrastructure.[19]
• Pharmaceutical businesses have to take extra care to collect and organize the data in a way that is conducive to analysis because a significant amount of it is in free text format. [20] Notwithstanding these drawbacks, AI is unquestionably already transforming the pharmaceutical and biotech sectors.
