Artificial Intelligence (AI) is becoming a revolutionary tool in the scientific and medical field, especially in drug discovery. One example is the recent study in the journal Nature Chemical Biology, which tells how AI has played a vital role in finding a new antibiotic to combat Acinetobacter baumannii, a bacterium known for its resistance to drugs. This article explores the role of this technology in the development of new drugs, its evolution, and current applications in medicine. Also, the risks and ethical considerations it brings, and how we can prepare for its future.
The application of Artificial Intelligence to identify and develop new drugs marks a spectacular change in this field. Instead of relying entirely on conventional trial-and-error drug discovery methods, this approach uses advanced algorithms capable of efficiently analyzing, filtering, and classifying chemical compounds.
This methodology is especially relevant in the face of growing resistance to antibiotics. The evolution of drug-resistant bacteria is a global problem and AI, with its ability to discover new compounds and therapies, presents itself as a valuable ally. With its ability to analyze large data sets and provide meaningful insights, AI holds promise for the future of medicine.
AI can also be useful in drug development and testing, modeling interactions between compounds and their biological targets and anticipating potential side effects. This can help streamline the drug development process and ensure that they are safe and effective.

Evolution and current applications
Since its inception, AI has advanced significantly in medicine. In the 1960s, this technology was rudimentarily applied in expert systems such as MYCIN, which used heuristic rules to diagnose infectious diseases. However, his limitation lay in the inability to learn from new data and situations.
With the incorporation of machine learning, AI began to have a greater presence in medicine. Machine learning algorithms, capable of learning from data and improving over time, are especially valuable in fields with vast and complex data such as medicine.
Artificial Intelligence is applied in various medical contexts, from image interpretation to diagnostic and treatment support. For example, in medical image analysis, advanced algorithms identify patterns and abnormalities in X-rays and MRIs that may indicate specific diseases, enabling early and accurate detection.
In diagnosis and treatment, systems based on artificial intelligence process large amounts of patient data, assisting doctors in their decisions. These systems can suggest treatments based on the latest evidence and individual patient characteristics.
More recently, text-text generative AI has emerged, used in healthcare chatbots that interact with patients, answer their questions and offer recommendations based on their symptoms.
Risks and ethical considerations
Artificial Intelligence in medicine presents both advantages and risks and ethical issues. One risk is over-reliance on these technologies, which could lead to over-reliance on AI by healthcare professionals, affecting the quality of healthcare.
Another concern is the potential for incorrect diagnoses or treatment resulting from algorithms based on unreliable information or skewed data. This highlights the need for supervision by health professionals.
On the ethical side, bias in algorithms, whether inadvertent or intentional, can lead to detrimental results. It is vital to identify and eliminate these biases. In addition , the privacy and confidentiality of health data are significant concerns, making the secure handling of this data necessary.
Finally, legal frameworks must keep up with advances in AI in healthcare. Organizations such as the WHO are working on standards and guiding principles for their safe and ethical use, seeking to benefit patients and society.
What does the future hold?
Looking ahead, AI is expected to have an even greater impact in healthcare, with the potential to transform disease diagnosis, prognosis, treatment and monitoring. However, this path to the new digital era in medicine comes with its set of challenges that need to be addressed carefully and effectively. These include:
Continuing education and training: The role of Artificial Intelligence in medicine is rapidly evolving, making continuous education necessary for both future doctors and practicing professionals. The goal is to develop a solid understanding of AI, its potentials and limitations, in order to be able to use these tools safely and efficiently.
Transparency and explainability: For medical professionals to trust and effectively use AI tools, it is crucial that the algorithms used are transparent and understandable. They must understand how these systems work, what their sources of information are, and how data security is ensured.
Robust regulatory framework: With the proliferation of AI in medicine, a robust regulatory framework is needed that protects patient privacy, prevents bias and discrimination, and ensures that technologies are used ethically.
Cross-Sector Participation: Medicine cannot face the challenges posed by AI alone. Close collaboration with other sectors, including education, government policy, regulators and other key players in society, is essential.
Patient-Centric Approach: Above all else, it is vital that the development and use of AI in medicine be done with the patient at the center. This implies respecting the rights of the patient, including the right to information, informed consent and data privacy.
Public health organizations, such as the Pan American Health Organization, are collaborating with different ministries to address these challenges. Although the path is complex, with proper planning and a patient-centric approach , AI has enormous potential to improve healthcare and public health globally.
