what is research gap of drug research and give me few examples with it, especial in Papua new guinea

The research gap in drug research refers to the lack of knowledge or understanding in a particular area of pharmaceutical science or medicine that needs to be addressed by further research. In Papua New Guinea, there are several research gaps in drug research that could be explored, such as:

1. Lack of research on traditional medicine: Papua New Guinea has a rich history of traditional medicine practices, but there is limited scientific research on the safety and efficacy of these traditional remedies. Further research is needed to explore the potential benefits and risks of traditional medicines and to integrate them with modern medical practices.

2. Limited research on local plant and animal species for drug discovery: Papua New Guinea is known for its diverse flora and fauna, which could potentially be a source of novel drug compounds. However, there is a lack of research on local plant and animal species for drug discovery. More studies are needed to investigate the pharmacological properties of these species and their potential as sources of new medicines.

3. Insufficient research on drug resistance: Drug resistance is a growing concern globally, including in Papua New Guinea. There is a need for more research on the mechanisms of drug resistance, as well as strategies to combat resistance in infectious diseases such as malaria and tuberculosis.

Overall, addressing these research gaps in drug research in Papua New Guinea could lead to the development of new and more effective medicines, as well as a better understanding of the country's traditional healing practices and biodiversity.
