Pharmacokinetics and Pharmacodynamics
Conditions
Brief summary
The present study is designed to compare the pharmacokinetic, pharmacodynamic and safety characteristics of UBLIN® (test product) and NovoRapid® (reference product) in healthy male participants. The treatment consists of one single dose of the test or reference product, administered during each of the two study periods, separated by 7 days between dosing. A total of 44 participants will be enrolled in this trial and randomized in a 1:1 ratio into two groups (A/B), stratified by race (Asian, non-Asian).

History of hereditary galactose intolerance, lactase deficiency, or glucose-galactose malabsorption; 3. Has clinically significant abnormal conditions requiring exclusion, including but not limited to system disorders of the nervous, cardiovascular, hematological and lymphatic, immune, renal, hepatic, gastrointestinal, respiratory, metabolic, and skeletal systems, especially a history of hypoglycemia, hypokalemia, orthostatic hypotension, syncope or blackout, diabetes mellitus, or a family history of diabetes mellitus (first-degree relatives); 4. Has a history of severe vomiting, diarrhoea within 7 days prior to the trial, or has any other disease or physiological condition that may interfere with the trial results; 5. Has undergone surgery within 3 months prior to the study, or plans to undergo surgery during the study period; or has undergone any surgery that may affect drug absorption, distribution, metabolism, or excretion; 6. Has a history of asthma or epilepsy; 7. Has participated in any other investigational product or device clinical trial and received investigational product within 6 months prior to the study; 8. Has taken any medications that alter liver enzyme activity within 28 days prior to the trial (common liver enzyme inducers: barbiturates (phenobarbital is the most common), carbamazepine, aminoglutethimide, griseofulvin, meprobamate, phenytoin, glutethimide, rifampicin, dexamethasone; common liver enzyme inhibitors: chlorpromazine, cimetidine, ciprofloxacin, metronidazole, chloramphenicol, sulfonamides); 9. Has taken any medications that affect the hypoglycemic effect of insulin within 28 days prior to the trial (e.g., corticosteroids, danazol, diazoxide, diuretics, epinephrine, albuterol, terbutaline, glucagon, growth hormone, thyroid hormones, beta-blockers, etc.); 10. Has used any prescription drugs, over-the-counter drugs, health products, traditional Chinese medicines, or received vaccinations within 14 days prior to the trial; 11. Has any clinically significant abnormality identified by the investigator in general physical examination, laboratory tests (including hematology, blood biochemistry, coagulation, urinalysis, etc.), or 12-lead ECG within 14 days prior to the study; 12.
