The Effect of Andrographis Paniculata to GLP-1, Fasting Insulin, Insulin 2-h Post OGTT, and HOMA-IR in Normal and Prediabetes Subject

Prevalence of type 2 diabetes have been increased, but medications had not been well, so that needed new alternatives. A new approach used in management of type 2 diabetes is incretin based therapy. Incretin hormone, glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotrophic peptide (GIP), had producted in intestine due to carbohydrate intralumen. After had secreted, GLP-1 had degradated by DPP-4 enzyme till number and effect had been decreased. Decreasing of GLP-1 effect as main defect in type 2 diabetes.

Andrographis paniculata (A. paniculata) as traditional treatment had known since years ago to have hypoglycemia effect. Extract of A. paniculata consists of andrographolid and flavonoid. Based on study of Wooten et al that flavonoid has hydroxyl to stimulate insulin's production through modulated GLP-1 receptor (GLP-1 receptor ligand). So the investigators need to study about The Effect of A. paniculata Extract to GLP-1, Fasting Plasma Insulin, Insulin concentrations measured during a standardized 2-h OGTT, and HOMA-IR.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Blood's participants will be examined fasting plasma insulin and glycated albumin (from fasting blood) and insulin measured during a standardized 2-h OGTT, DPP-4 enzyme, and GLP-1 (from standardized 2-h OGTT blood). Then, complete urinalysis test. Participants will be randomized to be two groups are group have been intervenced by capsules of A. paniculata or group placebo. Each group will be explained about procedure to consume capsules A. paniculata or placebo for 14 days, storage procedures, and the way to contact the investigators if adverse event happened. The investigators will contact participants to remember the schedule to consume capsules A. paniculata, ask whether the side effects or not, and ask the result of self monitoring blood glucose every three days by glucose meter have been given.

Before day 12th, participants will be contacted to come in visit 2nd. In visit 2nd (day 15th) will be done anamneses, assessment of compliance, reporting adverse event and side effect, physical examination, fasting plasma glucose test, fasting insulin, HOMA-IR, GA and complete urinalysis. Then, will be done standardized 2-h OGTT. Two hours later, it will be done plasma glucose level, insulin, DPP-4 enzyme, and GLP-1. Participants will be explained that they will not receive capsules of A. paniculata for 7 days (day 15th till 21th). This is called wash out.

Participants will be explained about procedures to consume capsule of A. paniculata or placebo in day 22th till 35th. Before day 32th, participants will be contacted to come in visit 3rd (day 36th). In visit 3rd, will be done anamneses, assessment of compliance, reporting adverse event and side effect, physical examination, fasting plasma glucose test, fasting insulin, HOMA-IR, GA and complete urinalysis. Then, will be done standardized 2-h OGTT. Two hours later, it will be done plasma glucose level, insulin, DPP-4 enzyme, and GLP-1.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
