Pharmacokinetics is currently defined as the study of the time course of drug absorption, distribution, metabolism, and excretion. Primary goals of pharmacokinetics include enhancing efficacy and decreasing toxicity of drug therapy. These parameters have enabled clinicians to apply pharmacokinetic principles to actual patient situations. Pharmacodynamics refers to the relationship between drug concentration at the site of action and the resulting effect, including the time course and intensity of therapeutic and adverse effects. Pharmacodynamics places a particular emphasis on dose–response relationships, it provides an important parameter for the clinical application of drugs.

raphitic carbon nitride (g-C3N4) is a planar two-dimensional sheet structure similar to graphene, with two basic units, based on triazine ring (C3N3) and 3-s-triazine ring (C6N7) respectively the structural units extend infinitely to form a network structure, and the two-dimensional nanosheets are combined by van der Waals forces. g-C3N4 has become an important material in the fields of chemistry, physics, and medicine due to its simple preparation method, low cost, environmental friendliness, good stability, and good physical and chemical properties. The most common precursors used to prepare g-C3N4 are melamine, dicyandiamide, cyanamide, urea, thiourea, and ammonium thiocyanate. To enhance the performance and tuning properties of g-C3N4, heterojunctions can be doped and fabricated with other materials. Among these materials can be metal oxides, metal sulfides, noble metals and carbon nanomaterials. Among them, metal oxides are the most common method to improve the efficiency of g-C3N4. The g-C3N4 structure has been widely used in many applications, and in addition to energy-related applications, its application in the field of drug delivery has also received increasing attention from scientists. Studies have shown that g-C3N4 is an effective nanocarriers and can be used for the delivery of many drugs. The adsorption energy of g-C3N4 is about high, and the high adsorption energy indicates that g-C3N4 can form stable complexes with the loaded drugs. The resulting complex system has a higher dipole moment value, which improves the solubility of the complex. Furthermore, after the complex formation of g-C3N4 and the drug, its higher hydrophilicity facilitates drug transfer in the in vivo physiological environment.
