Research progress on new dosage forms of progesterone and its preparation methods / 药学学报

Progesterone is currently the first-line drug for the treatment and prevention of threatened abortion and habitual abortion. With the gradual liberalization of China's childbirth policy, the number of elderly parturients has increased significantly. As a result, the market demand for progesterone and the individual requirements have been continuously improved. Clinical studies have found that the indications of progesterone are not limited to gynecological diseases, but can also be used for the treatment of renal colic, traumatic brain injury and other diseases. Existing progesterone preparations include oral capsules, intramuscular injections, vaginal gels, etc., but they can no longer meet the current market situation and the increase of indications. Improving existing preparations, developing new preparations, and opening up new routes of administration have become one of the directions of progesterone drug research. This article will review the research progress of new dosage forms in existing administration, new routes of administration and related preparation methods of progesterone.

Efficacy of Hangekobokuto on Patients with Functional Dyspepsia, with Special Reference to its Clinical Indication and Gastrointestinal Function / 日本東洋医学雑誌

We have limited evidence as to the clinical indications for Kampo medicines, especially as they relate to gastrointestinal function. Thus, we investigated the efficacy of the Kampo medicine hangekobokuto (HKT) on patients with functional dyspepsia (FD), with special reference to its clinical indications for gastrointestinal function, including gastric emptying and bowel gas volume.Gastric emptying rate (GER) in FD patients was significantly facilitated by HKT. HKT also improved the gastrointestinal symptoms of the patients. Among these, patients who had inchuusharen, or a symptom of globus sensation, and a representative indication for HKT, showed significant improvement of both their GER and gastrointestinal symptoms compared with patients who did not have inchuusharen. As for bowel gas, the bowel gas volume calculated from a plain abdominal radiogram (gas volume score, GVS) in FD patients decreased significantly, after administration of HKT. Patients who had fukuman, or a feeling that one's stomach is full or bloated, and another representative indication for HKT, showed significant decrease of their GVS to normal levels, compared with patients who did not present with fukuman.These results suggest that the presence of clinical indications, such as inchuusharen or fukuman, are strongly related to HKT efficacy in patients with FD, and that these are useful, scientifically validated markers for the efficient use of HKT.
