Medically reviewed on Mar 1, It is a white to off-white powder with a molecular weight of Acarbose precose 25 mg 5 ml soluble in water and has a pKa of 5. Its empirical formula is C 25 H 43 NO 18 and its chemical structure is as follows:. Precose is available as precose mg, 50 mg and mg tablets for oral use. The inactive ingredients are starch, microcrystalline cellulose, magnesium stearate, and colloidal silicon dioxide.
Acarbose is a complex oligosaccharide that delays the digestion of ingested carbohydrates, thereby resulting go continue reading a smaller rise in blood glucose concentration following meals.
As a consequence of precose 25 mg 5 ml glucose reduction, Precose reduces levels of glycosylated hemoglobin in patients with type 2 diabetes mellitus. Systemic non-enzymatic protein glycosylation, precose reflected by levels of glycosylated hemoglobin, is a function of average blood glucose concentration over time. In contrast to sulfonylureas, Precose does not enhance insulin glucophage for what. The antihyperglycemic action of precose 25 mg 5 ml results from a competitive, reversible inhibition of pancreatic alpha-amylase and membrane-bound intestinal alpha-glucoside hydrolase enzymes.
Pancreatic precose hydrolyzes complex starches to oligosaccharides in the lumen of the small intestine, while the membrane-bound intestinal alpha-glucosidases hydrolyze oligosaccharides, trisaccharides, and disaccharides to glucose and other monosaccharides in the precose 25 mg 5 ml border of the small intestine.
In diabetic patients, this enzyme inhibition results in a delayed glucose absorption and a lowering of postprandial hyperglycemia.
Because its mechanism of action is different, precose 25 mg 5 ml effect of Precose to enhance glycemic control is additive to that of sulfonylureas, insulin or metformin when used in combination.
In addition, Precose diminishes the insulinotropic and weight-increasing effects of sulfonylureas. Acarbose /furosemide-for-high-blood-pressure-naturally.html no inhibitory activity against lactase and consequently would not be article source to induce lactose intolerance. Because acarbose acts locally precose 25 mg 5 ml the gastrointestinal tract, this low systemic bioavailability of parent compound is therapeutically desired.
Following oral dosing of healthy volunteers with 14 C-labeled acarbose, peak plasma concentrations of radioactivity precose 25 mg 5 ml attained 14—24 hours after dosing, while peak plasma concentrations of active drug were attained at approximately 1 hour.
The delayed absorption of acarbose-related radioactivity precose 25 mg 5 ml the absorption of metabolites that may be formed by either intestinal bacteria or intestinal enzymatic hydrolysis. Acarbose is metabolized exclusively within the gastrointestinal tract, principally by intestinal visit web page, but also by digestive enzymes.
At least 13 metabolites have been separated chromatographically from urine specimens. The major metabolites have been identified as 4-methylpyrogallol derivatives that is, sulfate, methyl, and glucuronide conjugates. One metabolite formed by cleavage of a glucose molecule from acarbose also has alpha-glucosidase inhibitory activity.
Here precose 25 mg precose 25 mg 5 ml ml of acarbose that is absorbed as intact drug is almost completely excreted by the kidneys. This is consistent with the low bioavailability of the parent drug.
The plasma elimination half-life of acarbose activity is approximately 2 hours in healthy volunteers. Consequently, drug accumulation does not precose 25 mg 5 ml with three times a day t. The mean steady-state area under the curve AUC and maximum concentrations of acarbose were approximately 1. No studies of acarbose pharmacokinetic parameters according to race have been precose 25 mg 5 ml. Studies in healthy volunteers have shown that Precose has no effect on either the pharmacokinetics or pharmacodynamics of precose, propranolol, or ranitidine.
Precose did not interfere with the absorption or disposition of the sulfonylurea glyburide in diabetic patients. The amount of metformin /lopid-vs-lipitor-vs-zocor-doctor-opinions.html while taking Precose was bioequivalent to the amount absorbed when taking placebo, as indicated by the plasma AUC values.
There is little if any clinically significant interaction precose 25 mg 5 ml Precose precose 25 mg 5 ml precose 25 mg 5 ml. Results from six controlled, fixed-dose, monotherapy studies of Precose in the treatment of type 2 diabetes mellitus, involving Precose-treated patients, were combined precose 25 mg 5 ml a weighted average of the difference from placebo in the mean change from baseline in glycosylated hemoglobin HbA1c ventolin hfa aerosol vs qvar calculated precose 25 mg 5 ml each dose level as presented below:.
Results from these six fixed-dose, monotherapy 500 take can you mg and advil naproxen aleve were also precose to derive a weighted average of the difference from placebo in mean change from baseline for one-hour postprandial plasma glucose levels as shown in the following figure:. Precose regimen was superior to lower doses, but there were no statistically significant precose 25 mg 5 ml from 50 to mg t.
