部分中文盐酸考来维仑处方资料(仅供参考)

    美国Sankyo Pharma公司宣布Colesevelam(商品名WelChol)作为一种新的降低胆固醇的药物已在全美国投放市场,可供医师和病人选用。
  WelChol不但可以单独使用降低LDL胆固醇,而且还是唯一的经FDA批准的可与他汀类药物联合使用的降脂药。对以胆固醇升高为主的高脂血症,当饮食和锻炼不能很好达到效果时, WelChol单独使用或与他汀类合用可有效的降低血浆胆固醇。
  WelChol的一个优点是它与其他常用的降低胆固醇的药物不同,它不被吸收入血而散布全身。美国芝加哥临床研究中心主席Michael Davidson教授在评价这种新药时说:“对于血浆胆固醇较高而正在服用其他降脂药的病人来说,WelChol是他们的福音,因为它不被吸收的特性决定了它无全身副作用,这些副作用在其他降脂药中很常见。这使得已经服药很久的病人可以在加服WelChol的同时继续服用其他降脂药。”
  此外,WelChol与其他药之间的交叉反应也很小。在药物交叉反应研究中,WelChol没有明显的影响地高辛、洛伐他汀、奎尼丁和华法令等药的吸收,而这些药却与其他降脂药之间却有显著的反应。尽管如此,病人还是应该在服用WelChol之前将他们正在服用的药物告诉他们的医生。
  一项调查显示,尽管国家胆固醇教育计划(NCEP)中列出了降低胆固醇的指导方针,但仅有54%的患有高胆固醇血症的被调查者知晓他们的降脂目标。另一项称为血脂治疗评估计划(L-TAP)的研究指出,在患有高胆固醇血症的被调查者中,仅有38%接受降脂治疗的病人达到了NCEP要求的胆固醇降低的目标水平。为此,Sankyo Pharma的负责人William L. Bailey说:“L-TAP研究表明对于难以达到降脂目标水平的病人来说,的确需要在现有药物治疗之上找到更好的辅助药物。我们临床试验表明,在降低LDL-c方面WelChol是有效的和安全的。特别是当WelChol与他汀类药物(如洛伐他汀、辛伐他汀等)联合使用时,WelChol能够很好的达到降低胆固醇的作用,且这种效果是单用其中一种药物所达不到的。”美国贝勒医学院的Peter H. Jones教授指出:“WelChol与他汀类药物合用可显著改善病人的血脂水平,以达到NCEP的目标水平。此外如果病人不能耐受他汀类药物,单独使用WelChol也能有很不错的效果。”

Welchol (colesevelam hydrochloride)
Company: Daiichi Sankyo
Approval Status: Approved January 2008
Treatment for: glycemic control in type 2 diabetes mellitus
Areas: Endocrinology

General Information
Welchol contains colesevelam hydrochloride, a non-absorbed, polymeric, lipid-lowering and glucose-lowering agent. It works by binding bile acids, including the major bile acid in humans known as glycocholic acid. However, the exact mechanism by which Welchol improves glycemic control is unknown.

Welchol is specifically indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Welchol is supplied as a 625 mg tablet designed for oral administration. The recommended initial dose of the drug is 6 tablets once daily or 3 tablets twice daily. Welchol should be taken with a meal and liquid.

Clinical Results
FDA Approval
The FDA approval of Welchol for this indication was based on the results of three clinical trials. These double-blind, placebo-controlled add-on therapy trials enrolled a total of 1,018 subjects with baseline A1C 7.5-9.5%. The subjects received Welchol, in combination with metformin, sulfonylureas or insulin or placebo administered either as 3 tablets twice daily with lunch and dinner or as 6 tablets with dinner alone.

Add-on Combination Therapy with Metformin:
Welchol 3.8 g/day or placebo was added to background anti-diabetic therapy in a 26-week trial of 316 subjects already receiving treatment with metformin alone (N=159) or metformin in combination with other oral agents (N=157). The combination of Welchol plus metformin resulted in statistically significant placebo-corrected reductions in A1C with a -0.6 treatment difference (p<0.001) and FPG with a -14 treatment difference (p=0.10). The mean percent change in serum LDL-C levels with Welchol compared to placebo was -16% among statin users and statin non-users; the median percent change in serum TG levels with Welchol compared to placebo was -2% among statin users and 10% among statin non-users. The mean change in body weight was -0.5 kg for Welchol and -0.3 kg for placebo.

Add-on Combination Therapy with Sulfonylurea:
Welchol 3.8 g/day or placebo was added to background anti-diabetic therapy in a 26-week trial of 460 patients already treated with sulfonylurea alone (N=156) or sulfonylurea in combination with other oral agents (N=304). In combination with a sulfonylurea, Welchol resulted in statistically significant placebo corrected reductions in A1C and FPG. Welchol also reduced TC, LDL-C, Apo B, and non-HDL-C, but increased serum TG (Table 11). The mean percent change in serum LDLC levels with Welchol compared to placebo was -18% among statin users and -15% among statin non-users; the median percent increase in serum TG with Welchol compared to placebo was 29% among statin users and 9% among statin non-users. The mean change in body weight was 0.0 kg for Welchol and -0.4 kg for placebo.

Add-on Combination Therapy with Insulin:
Welchol 3.8 g/day or placebo was added to background anti-diabetic therapy in a 16-week trial of 287 patients already treated with insulin alone (N=116) or insulin in combination with oral agents (N=171). At baseline, the median daily insulin dose was 70 units in the Welchol group and 65 units in the placebo group. In combination with insulin, Welchol resulted in a statistically significant placebo-corrected reduction in A1C (Table 12). Welchol also reduced LDL-C and Apo B, but increased serum TG (Table 13). The mean percent change in serum LDL-C levels with Welchol compared to placebo was -13% among statin users and statin non-users; the median percent increase in serum TG levels with Welchol compared to placebo was 24% among statin users and 17% among statin non-users. The mean change in body weight was 0.6 kg for Welchol and 0.2 kg for placebo.

Mechanism of Action
Colesevelam hydrochloride, the active pharmaceutical ingredient in Welchol, is a non-absorbed, lipid-lowering polymer that binds bile acids in the intestine, impeding their reabsorption. However, the exact mechanism by which Welchol improves glycemic control is unknown.
