Sometimes patients with type 2 diabetes might need to change to treatment with insulin for a short period of time during pregnancy or for a serious medical condition, such as diabetic coma; ketoacidosis; severe injury, burn, or infection; or major surgery. In these conditions, insulin and blood sugar can change fast and blood sugar can be best controlled with insulin instead of a sulfonylurea. At first, 1000 to 2000 milligrams mg a day. Some elderly people may need lower doses to start. The dose is usually divided into two doses. These doses are taken before the morning and evening meals. Your doctor may change your dose a little at a time if needed. The dose is usually not more than 3000 mg a day. chloromycetin price check

The effect on the nursing infants is not known. The American Academy of Pediatrics considers tolbutamide to be compatible with breast-feeding. With chronic sulfonylurea treatment, insulin production is not increased and may return to pretreatment values, but insulin efficacy continues and is thought to involve extrapancreatic mechanisms to increase insulin sensitivity in target tissues, such as liver, muscle, and fat as well as in other cells, such as monocytes and erythrocytes. This can result in a decrease in hepatic glycogenolysis and gluconeogenesis. It is unclear if the sulfonylurea's extrapancreatic actions that increase insulin's efficacy are direct or indirect effects, but it is clear that the mechanism of action is not due to a direct sulfonylurea action on the insulin receptor. Because this peripheral effect is not apparent in patients with type 1 diabetes, the evidence suggests that this may not be the clinically significant mechanism of sulfonylurea action in patients with type 2 diabetes either. However, it is clear that tissues of sulfonylurea-treated patients with type 2 diabetes become more responsive to lower concentrations of endogenous insulin. Primary failure of sulfonylurea therapy may occur if beta-cell function is severely impaired. Studies in male and female rats given 75 times the maximum human dose showed no evidence of impaired fertility. Lower initial dose may be required. Chlorpropamide Apo-Chlorpropamide, Apotex.

Sulfonylureas lower blood glucose in patients with type 2 diabetes by directly stimulating the acute release of insulin from functioning beta cells of pancreatic islet tissue by an unknown process that involves a sulfonylurea receptor on the beta cell. Sulfonylureas inhibit the ATP-potassium channels on the beta cell membrane and potassium efflux, which results in depolarization and calcium influx, calcium-calmodulin binding, kinase activation, and release of insulin-containing granules by exocytosis, an effect similar to that of glucose. Insulin is a hormone that lowers blood glucose and controls the storage and metabolism of carbohydrates, proteins, and fats. Sulfonylureas are effective only in patients whose pancreata are capable of producing insulin. Doucet J, Fresel J, Moore N, et al.

Combination insulin-glimepiride therapy may increase the potential for development of hypoglycemia. Attempts should be made to identify the minimum effective dose of each drug. Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Not recommended for use in patients with renal function impairment.

Using an in vitro method and whole embryo mouse culture, one study compared growth differences between untreated embryos and those bathed in hypoglycemic and euglycemic chlorpropamide-treated rat serums. The teratologic evaluation of the treated early somite mouse embryos showed malformations and growth retardation at doses similar to human therapeutic concentrations, which suggested that the teratogenicity was due to chlorpropamide and not to hypoglycemia; untreated mouse embryos showed normal development. Studies in humans have not been done. Use should be discontinued at least 2 weeks before the expected delivery date. F in a tight container, unless otherwise specified by manufacturer. Not included in Canadian product labeling. Oral, 8 mg once a day with breakfast or the first main meal. Sometimes insulin that is being produced by the body is not able to help sugar get inside the body's cells. Sulfonylureas help insulin get into the cells where it can work properly to lower blood sugar. In this way, sulfonylureas will help lower blood sugar and help restore the way you use food to make energy. letrozole

Salicylates, in large doses these medications have intrinsic hypoglycemic activity in both diabetic and nondiabetic patients, possibly severe with quinine, quinidine, or salicylates in high doses but unlikely with low doses of salicylates.

Curr Ther Res Clin Exp; 1993; 53: 329-39. During conversion from insulin therapy to tolbutamide therapy, no gradual dosage adjustment usually is required for patients using less than 20 USP Units of insulin daily. Patients using 20 to 40 USP Units require a 30 to 50% reduction in insulin the first day with gradual dosage adjustment as needed. Patients requiring more than 40 USP Units should receive a 20% reduction of insulin the first day with gradual dosage adjustment of tolbutamide as needed. Hospitalization for some patients on a higher insulin dosage may be required for uneventful conversion. Other side effects not listed above may also occur in some patients. If you notice any other effects, check with your doctor. Glucose administration is the basis for treatment of hypoglycemia; however, an exposure to sudden or excessive hyperglycemia caused by an injection of hypertonic glucose solution may further stimulate the sulfonylurea-primed pancreas to release more insulin, worsening the hypoglycemia.

It occurs more often with long-acting sulfonylureas, such as chlorpropamide or glyburide, when other predisposing factors or conditions are present, and can be relapsing and prolonged; glyburide results in a higher fatality rate than does chlorpropamide.

Predisposing factors related to diet, exercise, age, or concurrent use of other hypoglycemia-causing drugs including insulin increase the chances of hypoglycemic episodes occurring. The occurrence of a recent episode of hypoglycemia may lessen the symptoms of a second episode. In the elderly, hypoglycemia symptoms are variable and harder to identify. Furthermore, nocturnal hypoglycemia may be asymptomatic in 33% or more of affected patients. Hypoglycemic episodes are experienced by 20% of the patients taking sulfonylureas every 6 months 6% experiencing monthly episodes.
Chlorpropamide crosses the placenta. Sulfonylureas should not be used during pregnancy, especially when insulin is available. In the rare cases that a sulfonylurea is used, chlorpropamide and glipizide should be discontinued at least 1 month before delivery date and other sulfonylureas stopped at least 2 weeks before delivery date. Maintenance: Oral, 250 to 1000 mg once a day before breakfast or 1000 to 1500 mg divided into two doses taken before breakfast and evening meals. Know what to do if high blood sugar occurs. Your doctor may recommend changes in your sulfonylurea dose or meal plan to avoid high blood sugar. Symptoms of high blood sugar must be corrected before they progress to more serious conditions.
