Dosage forms and methods of use are disclosed for: a) the simultaneous administration of tetrahydrobiopterin (BH4) or a derivative, homolog or precursor thereof and lipoic acid (LA), or dihydrolipoic acid (DHLA), or a derivative, homolog or salt thereof or, b) the administration of a conjugate consisting of tetrahydrobiopterin bis-lipoate (TBL). The invention is useful for the amelioration of diabetes mellitus types 1 and 2 (including impaired glucose tolerance, pre-diabetes, insulin resistance, metabolic syndrome X and as an adjunct to oral antidiabetic agents and/or insulin), diabetic and non-diabetic microvascular diseases (including nephropathy, neuropathy and retinopathy), diabetic and non-diabetic macrovascular diseases (including heart attack, stroke, peripheral vascular disease and ischemia-reperfusion injury), hypertension, vasoconstriction, obesity, dyslipedemia, and neurodegenerative disorders (including Parkinson's disease, mild cognitive impairment, senile dementia, Alzheimer's disease, hearing loss and chronic glaucomas). A novel method for the preparation of TBL is also disclosed.
本发明揭示了以下的剂型和使用方法:a) 同时给药四氢生物蝶啶(BH4)或其衍生物、同系物或前体以及硫辛酸(LA)或二氢硫辛酸(DHLA),或其衍生物、同系物或盐;b) 给药由四氢生物蝶啶双硫辛酸酯(TBL)组成的结合物。本发明可用于改善糖尿病类型1和2(包括糖耐量受损、糖尿病前期、胰岛素抵抗、代谢综合征X以及作为口服抗糖尿病药物和/或胰岛素的辅助剂),糖尿病和非糖尿病微血管疾病(包括肾病、神经病变和视网膜病变),糖尿病和非糖尿病大血管疾病(包括心脏病发作、中风、外周血管疾病和缺血再灌注损伤),高血压、血管收缩、肥胖、血脂异常和神经退行性疾病(包括帕金森病、轻度认知障碍、老年痴呆症、听力丧失和慢性青光眼)。本发明还揭示了一种制备TBL的新方法。
