Machine learning is a branch of artificial intelligence that deals with and focuses on algorithms, improving their accuracy through the collection of data, resembling human intelligence. Machine learning has been developed since its inception. It has become a vital resource in human resources as well. Nowadays, machine learning is not only used in technical and engineering fields but also in the medical field. It is employed in healthcare, treatment, drug discovery, and drug development, among other applications. Pharmacotherapeutics pertains to the use of drugs for prevention, treatment, diagnosis, and modification of normal functions. Machine learning has become imperative in the medical field, healthcare, drug discovery, and development. It is used in the development of a drug by creating a lead molecule and determining its effects on the body through technical methods. Machine learning is utilized in diagnostics, such as during EEG, ECG, MRI, CT scans, and many other diagnostic procedures. It is employed in clinical pharmacology where humans are used to measure drug effects. In academic practices for pharmacology subjects, software is used to calculate doses and conduct experiments technically, as it is prohibited to harm animals under PCI guidelines. Machine learning in pharmacotherapeutics plays a significant role in the medical field, aiding in drug discovery, drug development, diagnosis, and disease treatment. It is used in neural networks of artificial intelligence, where input and output act as neurons, contributing to the treatment of various diseases and disorders. In this manner, machine learning holds a distinct and vital role in pharmacotherapeutics.
