Drug development is a lengthy and intricate process that includes everything from preclinical to clinical studies. There is a rising interest in the Kingdom of Saudi Arabia (KSA) in supporting innovation, research, and local content, including clinical trials (Phase I-IV). There are now over 650 registered clinical trials in Saudi Arabia, with the number expected to grow. Medication use that is both safe and effective is an important part of drug research and clinical trials. Clinical pharmacology, or the study of how pharmaceuticals affect humans, is essential for making informed decisions during the drug development process. Pharmacokinetics, pharmacodynamics and pharmacogenomics are all aspects of clinical pharmacology. It's a rapidly growing area with numerous applications at all phases of life. Clinical pharmacology, as well as regulatory agency demands, will be included into research, enhancing the drug development process and speeding up the pipeline. Clinical pharmacology encompasses pharmacokinetics, pharmacodynamics, and pharmacogenomics. It's a fast expanding field with a wide range of uses for people at all stages of life. Clinical pharmacology, as well as regulatory agency requirements, will be included into research, speeding up the drug development process. Clinical pharmacology is also used in direct patient care to tailor treatment to the individual needs of the patient. Therapeutic drug monitoring, pharmacogenomics, and model-driven precision dosing are some of the methods used to optimise dose for particular patients Drug development is a long and intricate process that starts with preclinical research and ends with clinical trials.

Clinical pharmacology, or the study of how pharmaceuticals affect humans, is essential for making informed decisions during the drug development process. Pharmacokinetics, pharmacodynamics, and pharmacogenomics are all aspects of clinical pharmacology. Clinical pharmacology and regulatory agency requirements are both being included into research. It's a growing area with a variety of uses in drug development, including establishing optimal doses for Phase I, II and III studies, analysing bioequivalence and biosimilar research and designing clinical trials [1]. Clinical pharmacology, as well as regulatory agency demands, will be included into research, enhancing the drug development process and speeding up the pipeline. Clinical pharmacology is also utilised in direct patient care to personalise treatment to the patient's specific needs. Some of the approaches used to optimise dosage for specific patients include therapeutic drug monitoring, pharmacogenomics, and model driven precision dosing. In Saudi Arabia, clinical pharmacology is underutilised and we believe it is vital to raise awareness and educate the scientific community and healthcare professionals in the nation. Drug development is a long, demanding, and expensive process that begins with drug discovery and ends with well-organized clinical trials [2]. The Kingdom of Saudi Arabia (KSA) is becoming increasingly interested in fostering innovation, research, and indigenous content. Saudi Arabia is courting pharmaceutical companies and Contract Research Organisations (CROs) to conduct clinical trials. It's a rapidly growing topic with several applications in drug development, including selecting optimal doses for phase I, II, and III research. organising clinical studies and analysing bioequivalence and bio similar research Clinical pharmacology, as well as regulatory agency demands, will be included into research, enhancing the drug development process and speeding up the pipeline. Clinical pharmacology is also applied to direct patient treatment. Saudi Arabia already has approximately 650 clinical trials registered. This figure is believed to be rather low. In comparison, Poland, which has a similar GDP and population, has over 6400 clinical studies registered [3].

It is investigated if drug-drug interactions are mediated by metabolism or transporters. The researchers seek to investigate if the experimental medicine changes the PK of the other co-administered medications or if the interaction is clinically significant. Clinical drugdrug interaction studies are conducted after in vitro experiments that reveal a probable interaction. Saudi Arabia already has approximately 650 clinical trials registered. This figure is believed to be rather low. Poland, with a comparable Gross Domestic Product (GDP), might be utilised as a model. As stand-alone research, prospective clinical drugdrug interaction investigations are commonly undertaken in healthy volunteers. They are carried out early in the drug development process during phase I research and are not associated with any particular phase. To investigate drug-drug interactions, a powerful index perpetrator known to block or induce a certain metabolizing enzyme or transporter is utilised. The area under the curve or the percentage change in plasma concentration determines the magnitude of the interaction (AUC). A 20% shift in AUC is typically considered clinically significant. Saudi Arabia already has over 650 clinical trials registered [4,5].

This figure is believed to be rather low. An excellent example is Poland, which has a similar Gross Domestic Product (GDP). Because there is a need to personalize therapy based on patient related variables such as demographic information and genetic variety, we are moving away from a "one-size-fits-all" approach to personalized medicine in clinical practice. As contemporary clinical care adopts precision medicine, the integration and application of PGx and model-driven precision dosage in clinical practice will become increasingly critical. Precision dose based on PGx and model-informed precision dosages have the potential to improve clinical outcomes and reduce healthcare expenditures. As stand-alone research, prospective clinical drug-drug interaction investigations are commonly undertaken in healthy volunteers. They are carried out early in the drug development process during phase I research and are not associated with any particular phase. To analyse drug-drug interactions a strong index perpetrator recognized for preventing drug-drug interactions is employed.
