When was welchol approved for diabetes

Patients treated with colesevelam exhibited a moderate, but non-significant increase in triglyceride levels compared with placebo treatment difference: 4. In addition, 8. Similar results were seen in the insulin and sulfonylurea trials with regard to triglyceride levels. Change from baseline to endpoint in median high-sensitivity C-reactive protein hsCRP levels with addition of colesevelam HCl compared with placebo, to ongoing metformin, sulfonylurea or insulin antidiabetes therapies in patients with T2DM.

The addition of colesevelam to existing antidiabetes monotherapy or combination treatment suggests the potential benefit of its use in patients with early and established T2DM. While HDL-C levels increased from baseline with both colesevelam and placebo treatment, the changes were not significant. Compared with placebo, patients who received colesevelam had increased triglyceride levels [treatment difference: Although the addition of colesevelam to insulin therapy also resulted in reductions from baseline in total cholesterol, non-HDL-C, and HDL-C at week 16 figure 2 ; table 3 , these reductions were not significant compared with placebo.

In addition, patients treated with colesevelam exhibited a significant increase in triglyceride levels compared with placebo treatment difference: The addition of colesevelam resulted in a consistent reduction in HbA1c [ranging from 0. Colesevelam also reduced LDL-C and non-HDL-C levels when added to ongoing antidiabetes therapies, regardless of whether subjects were on ongoing monotherapy or combination therapy regimens. Colesevelam increased triglyceride levels; however, these increases were accompanied by reduced LDL-C, total cholesterol, and non-HDL-C levels, and increased HDL-C and in the lipoprotein ratios that typically denote increased cardiovascular risk.

Safety is an important issue in patients with T2DM who are often taking multiple medications to address the overall pathology of insulin resistance. Colesevelam, unlike most new pharmacological agents, has an established safety record and was generally well tolerated across all three trials in patients with T2DM.

The rate of adverse events AEs was similar between the colesevelam and placebo groups, and most AEs were considered unrelated to the study medication table 4.

Gastrointestinal disorders were the most common drug-related AEs experienced with colesevelam and included constipation occurring in 6. In the metformin trial, six patients 3. In the sulfonylurea trial, 12 patients 5. Most AEs were mild-to-moderate in severity and none of the serious AEs were considered to be drug-related.

The incidence of adverse events AEs following addition of colesevelam hydrochloride HCl or placebo to ongoing metformin, sulfonylurea or insulin therapy. AEs and serious AEs occurring during the randomized phase of each trial. The randomized period was 16 weeks in the insulin trial and 26 weeks in both the metformin and sulfonylurea trials.

AEs, adverse events; NA, not applicable. The risk of hypoglycaemia is an important consideration for any antidiabetes agent. In these three trials, colesevelam did not significantly increase the risk of hypoglycaemia when added to existing metformin-, sulfonylurea- or insulin-based therapy in patients with T2DM. In the metformin trial, one patient who received colesevelam experienced a mild episode of hypoglycaemia [ 26 ].

In the sulfonylurea trial, four patients 2. In the insulin trial, five patients 3. Overall, most episodes of hypoglycaemia were mild and resolved without discontinuation of treatment.

Mean changes in safety laboratory parameters and vital signs were similar in the treatment groups of each trial [ 26 — 28 ]. Overall, colesevelam was found to be weight neutral when added to existing antidiabetes treatment, which is another important consideration for patients with T2DM. Colesevelam can increase triglyceride levels in patients with T2DM.

Colesevelam has a high capacity for bile acid binding with a low potential for interfering with the absorption of other agents [ 34 ]. However, patients taking levothyroxine, oral contraceptives or glyburide should take these agents at least 4 h before colesevelam to avoid any potential for impaired absorption. Use of colesevelam may also decrease the absorption of fat-soluble vitamins including A, D and E [ 21 ]. The results of these trials are similar to those seen following the addition of thiazolidinediones to metformin or sulfonylurea therapy [ 35 ].

Currently, there are no data to show whether use of colesevelam reduces mortality or morbidity in patients with T2DM. Colesevelam is not approved for use in patients with type 1 diabetes and has not been studied in combination with the currently approved dipeptidyl peptidase-IV inhibitors sitagliptin or saxagliptin. In addition, there are limited data on its use in patients receiving thiazolidinediones.

The mechanism s by which colesevelam lowers glucose levels in patients with T2DM is not yet clearly understood. Bile acid activation of FXR has been shown to reduce expression of genes involved in gluconeogenesis including phosphoenolpyruvate carboxykinase and glucosephosphatase.

In addition, FXR may modulate hepatic glucose production during fasting and postprandial hepatic glucose utilization [ 37 — 40 ]. Emerging data suggest a partial regulatory role for FXR modulators in peripheral insulin sensitivity, suggesting a future role for FXR in the treatment of insulin resistance and T2DM [ 41 — 43 ].

Bile acids may also affect incretin release, having been shown to induce secretion of glucagon-like peptide-1 GLP-1 through activation of the G-protein-coupled receptor TGR5 [ 44 , 45 ].

The bile acid sequestrant colestimide was shown to result in increased secretion of GLP-1 in patients with T2DM, although the functional consequences are unclear [ 46 ]. Bile acids have also been implicated in metabolic regulation, through FXR-mediated regulation of energy substrate mobilization and storage [ 47 ]. These glycaemic effects appear to be unique to bile acid sequestrants, within which only colesevelam has been approved for improving glycaemic control in adults with T2DM.

It has not been studied in type 2 diabetes as monotherapy or in combination with a dipeptidyl peptidase 4 inhibitor and has not been extensively studied in combination with thiazolidinediones. The effect of Welchol on cardiovascular morbidity and mortality has not been determined. Welchol can increase serum TG concentrations particularly when used in combination with sulfonylureas or insulin.

Welchol may decrease the absorption of fat-soluble vitamins A, D, E, and K. Patients on vitamin supplements should take their vitamins at least 4 hours prior to Welchol. Caution should be exercised when treating patients with a susceptibility to vitamin K or fat soluble vitamin deficiencies.

Caution should also be exercised when treating patients with gastroparesis, gastrointestinal motility disorders, major gastrointestinal tract surgeryand when treating patients with dysphagia and swallowing disorders.

Welchol reduces gastrointestinal absorption of some drugs. Drugs with a known interaction with colesevelam glyburide,levothyroxine, and oral contraceptives [ethinyl estradiol, norethindrone] should be administered at least 4 hours prior to Welchol. Tell your HCP if you have any of these conditions. Cases of intestinal blockage have occurred. Discontinue Welchol and seek medical attention if severe abdominal pain or severe constipation occurs.

Welchol has known interactions with cyclosporine, glimepiride, glipizide, glyburide, levothyroxine, certain birth control pills, olmesartan medoxomil, and metformin extended-release ER. Welchol has not been studied with all combinations of drugs and supplements. Welchol for Oral Suspension is recommended for, but not limited to, use in appropriate pediatric patients, as well as any patient who has difficulty swallowing. Phenylketonurics: Welchol for Oral Suspension contains 27 mg phenylalanine per 3.

Phenylalanine can be harmful to patients with phenylketonuria PKU. You are encouraged to report negative side effects of prescription drugs to the FDA.

Three placebo tablets matching the active drug colesevelam in appearance, taken orally twice per day before breakfast and before the evening meal over a week treatment period. Outcome Measures. Fasting glucose concentrations were measured at baseline and 2 hours post-meal using the glucose oxidase method. HbA1c is the percent of red blood cell hemoglobin with glucose attached to it and an indicator of average blood glucose over the previous two to three months.

Fasting insulin levels were measured in the plasma using a chemiluminescence assay and is reported in nanomoles over 6 hours. EGP was measured using a triple-tracer mixed meal and calculated using the Steele's model, reported in micromoles per kilogram per minute.
