This invention belongs to the field of SNP site detection technology for guiding the use of second-generation antipsychotic drugs. Specifically, it relates to primer and probe combinations and applications for SNP site detection to guide personalized medication of second-generation antipsychotic drugs. The SNP site is rs17782313. The primer and probe combination includes an upstream primer SEQ ID NO:1 that specifically amplifies the wild-type T allele, an upstream primer SEQ ID NO:2 that specifically amplifies the mutant C allele, a universal downstream primer SEQ ID NO:3, a wild-type probe SEQ ID NO:4, and a mutant probe SEQ ID NO:5. This invention assesses the genetic risk of weight gain and metabolic disorders in patients with mental illness after taking second-generation antipsychotic drugs such as risperidone, quetiapine, amisulpride, and paliperidone through rapid and accurate genotyping. It features high specificity, high accuracy, speed, simplicity, and controllable cost, and can achieve rapid single-tube genotyping, providing key genetic evidence for the clinical development of personalized medication regimens.

The present invention pertains to the technical field of pharmaceutical preparations, and provides a novel solution-type quetiapine composition for transnasal administration. In the provided composition, quetiapine is completely dissolved therein in the form of a solution and administered transnasally. Compared with oral dosage forms on the market, the provided quetiapine solution-type transnasal preparation has particularly useful pharmacokinetic and pharmacodynamic profiles. Compared with other disclosed transnasal nano-emulsion forms, the composition of the present invention still has surprising pharmacokinetic and pharmacodynamic profiles, shows good clinical application prospects, and is expected to meet unmet clinical needs. On this basis, the present invention also provides a further improved high-saturation dissolution concentration technical solution and a further improved good chemical stability technical solution for preparing the quetiapine solution-type transnasal preparation.
