ABSTRACT
Nasal preparations have unique advantages in drug delivery and are widely used in the treatment of local and systemic diseases. Nasal administration of traditional Chinese medicine （TCM） has a long history in China. In recent years， nasal preparations of TCM have attracted wide attention. Based on the information about nasal preparations of TCM from the database of National Medical Products Administration （NMPA）， Yaozh.com and China National Knowledge Internet （CNKI） in the recent 30 years， the formulation， the listed products， commonly used TCM， pharmaceutical excipients， clinical application and safety research of modern nasal preparations of TCM were summarized and expounded. Focusing on many problems in the development of modern nasal preparations of TCM， such as inaccurate dosage of some products， incomplete quality standard system of pharmaceutical excipients， imperfect safety evaluation， lack of research and development of nasal drug delivery devices and so on， the possible solutions and prospects were put forward from the aspects of optimizing the extraction and separation process of TCM， the quality control and application method of pharmaceutical excipients， the development of new dosage forms， the safety evaluation of nasal administration of TCM， and the design and development of nasal administration devices. The aim is to provide ideas for the development of nasal preparations of TCM and provide scientific basis for its sustainable utilization.
ABSTRACT
As a major flavonoid in the leaves of Ampelopsis grossedentata, dihydromyricelin has attracted wide attention in recent years. The pharmacological effect of the dihydromyricelin is clear, but the limitation on the clinical application of this drug comes from its chemical properties and low bioavailability. Nowadays, researching on advanced pharmaceutical preparation and new dosage forms in order to improve its chemical properties has become hot spots. Based on the review of related literatures, we discussed the research progress on advanced pharmaceutical preparation and new dosage forms of dihydromyricelin, such as liposomes, microcapsules, microemulsions, solid dispersion, inclusion compound, floating gastroretentive drug, etc. The main purpose is to point out the shortages of existing research and provide a reference for further study.
ABSTRACT
Docetaxel (DXT)is a member of the taxane drug class,which is used to treat breast cancer,lung cancer,gastric cancer,prostate cancer and so on.Docetaxel can be used as a single agent or in combination with other chemotherapeutic drugs.Many side effects of docetaxel have been reported in recent years.New dosage forms are developed to reduce toxicity and increase efficacy.An overview of these novel formulations of docetaxel and clinical progress will be discussed by consulting 43 literatures.
ABSTRACT
In the middle of 1990 s, it was discovered that sirolimus had inhibitory effect on the proliferation of T lymphocytes , therefore, it is used for the treatment of anti-tumor cells.At present, the dosage forms of sirolimus are capsules , oral liquid and tab-lets.However, because of good fat-soluble and poor water-soluble property, its bioavailability is low with many side reactions .In order to provide reference for the further studies of sirolimus , the literatures in recent years were searched in Pubmed , Springer, CJFD,VIP Chinese periodical database and Wanfang data , and the research progress in the new dosage forms of sirolimus was summarized .
ABSTRACT
The main active components in Ginkgo biloba extracts were Ginkgo biloba flavonoids and lactone compounds. This pa-per reviewed on the kinds and pharmacological effects of the active ingredients in Ginkgo biloba extracts, and focused on four aspects including controlled-release preparations, solubilized solid preparations, nanoparticle formulations and time- and site-specific formula-tions to introduce the development in the new dosage forms of Ginkgo biloba flavonoids and lactone compounds.
