|Voglibose Usage And Synthesis|
|Oral hypoglycemic agents||Voglibose is an oral hypoglycemic agents which can alleviate the postprandial hyperglycemia of diabetes patients. It is first successfully developed by the Takeda Company in Japan. It belongs to α-glucosidase inhibitor (a drug which can delay the intestinal absorption of carbohydrates to achieve hypoglycemic effect). Its mechanism of action is through inhibiting the activity of disaccharides hydrolase (α-glucosidase) which can hydrolyze disaccharide into monosaccharide inside the gut and thus delaying the digestion and absorption of sugar and further alleviating the postprandial hyperglycemia. In the assay of measuring the exhaled hydrogen of healthy adults given sucrose loading, the results have confirmed that this drug in its clinical dosage has an inhibitory effect on hyperglycemia. When normal rats are subject to oral administration, this product can inhibit the increased blood sugar level after the increased loading of starch, sucrose, glucose and maltose, while it has no inhibitory effect on the increased blood sugar after increased loading of glucose, fructose, and lactose. In vitro analysis of mechanism of action have shown that, for the maltase and sucrose obtained from the small intestine of pig and rat, this drug has a strong inhibitory effect; on the other hand, it has a relative low inhibitory effect on the pancreatic α-amylase of pig and rat and has no inhibitory effect on β-glucosidase. It has a competitive inhibitory effect on the disaccharide hydrolase of the isomaltase-sucrase complex from the rat small intestine.|
It is understood that voglibose has a broad scope of application; it is not only suitable for elderly patients with diabetes, but also has significant efficacy on patients with refractory type II diabetes, patients with secondary failure of sulfonylureas, patients with combined hyperlipidemia diabetes, patients with merged cardiovascular diabetes disease as well as patients with combined hyperinsulinemia. Because this product does not stimulate the secretion of insulin, it can reduce the harmful effects of postprandial hyperinsulinemia, reducing the resistance of insulin and contributes to the prevention and treatment of metabolic syndrome such as cardiovascular complications.
|Side Effects||Mechanism of occurrence of side effects of oral administration of hypoglycemic agents is generally that: when the unabsorbed carbohydrate enters into the large intestine, under the action of bacteria, it subjects to glycolysis which produces carbon dioxide, hydrogen, and organic acids. At the same time, because of the increased osmotic pressure of intestinal, water retention happen which therefore causes increased exhausting, bloating, and diarrhea. Since voglibose can selectively inhibit the activity of the disaccharide hydrolase in the intestine, further delaying the rapid digestion and absorption of carbohydrate in the upper small intestine, and thus reducing saccharide, leading to a lower incidence of adverse reactions. It is known to have the following adverse reactions: |
1. The digestive system: diarrhea, loose stools, borborygumus, abdominal pain, constipation, loss of appetite, nausea, vomiting, heartburn (incidence of 0.1 to 5%), stomatitis, thirst, abnormal taste, and pneumatosis cystoides gastrointestinalis (0.1%).
2. Allergic symptoms: rash, itching, light sensitivity (incidence of 0.1% or less).
3. Liver: GOT, GPT, LDH, γ-GTP, ALP are increased (0.1% incidence).
4. The nervous system: headache, dizziness, staggering, drowsiness (0.1% incidence).
5. The blood system: anemia (incidence of 0.1 to 5%), thrombocytopenia (0.1%).
6. Other: paralysis, facial swelling, hazy eyes, fever, flu, tiredness, feeling of fatigue, hyperkalemia, rise of serum amylase, decrease of high-density lipoprotein, sweating, hair loss (incidence of 0.1%).
