Telmisartan (MicardisÂ/PritorÂ) protects against progression of diabetic nephropathy




The five year DETAILTM (Diabetics Exposed to Telmisartan And enalaprIL) enquiry randomised 250 patients next to sort 2 diabetes, hypertension and hasty raised area nephropathy to once respectively day telmisartan 80mg or the ACE-inhibitor enalapril 20mg. The foremost endpoint of the study be the amend from baseline bounded with glomerular filtration rate (GFR) - widely permitted by way of the most select weigh of overall kidney study in form and disease2 - after five years. The decline in GFR was parallel with telmisartan and enalapril.1 The study demonstrated that telmisartan was as powerful as enalapril in protecting opposed to the improvement of diabetic nephropathy.



DETAIL study published in The New England Journal of Medicine "DETAIL be meaningfully clinically to the tine. We prop alert it is the a minute ago long-term, knotty end-point comparison of an ARB and an ACE-inhibitor in early nephropathy. The grades tackle out long-term facts which endorse the renoprotective benefits of the ARB colloquium suggested by most recent study. This study agree with that telmisartan is a valid resolution all for first-line remedy of hypertensive patients with diabetic nephropathy. The industriousness that telmisartan is commonly effective as enalapril is specially encouraging in panorama of the superlative tolerability profile of ARBs relate with ACE-inhibitors." comment organize investigator Professor Anthony Barnett, Consultant Physician, Clinical Director of Diabetes and Endocrinology, Birmingham Heartlands and Solihull Hospitals and Professor of Medicine, University of Birmingham, United Kingdom.



Despite all DETAIL patients have type 2 diabetes, hypertension and nephropathy, cardiovascular mortality was only 5% in both numbers complete five years - largely belittle than would be programmed here high-risk group, to a degree of whom own a what budge fund of cardiovascular bug at baseline.1 Blood anxiety was lower in both groups to a comparable point over the trajectory of the torment.1 The study inclusion criterion unpreventable all patients to be forbearing of ACE-inhibitors. There be for this plea no focal difference in adverse communication linking the two drugs.1 However, ACE-inhibitors can be faultily adopt, with cough a rife haunch effect that can impact against merciful amazement.3 It is therefore respectable to document, that in two comparative studies of telmisartan and enalapril in patients who were not pre-selected for ACE-intolerance, telmisartan was superior tolerated.4,5 Professor Eberhard Ritz, Vice President of the International Society of Nephrology, at the Ruperto Carola University of Heidelberg, Germany, commented, "DETAIL is a much needed study that affix counterweight to the piece of proof for ARBs, and in precise, telmisartan. The DETAIL study undoubtedly suggest a breakthrough in our compassion of the admin of diabetic nephropathy. DETAIL transmission that treatment in the earliest stage of diabetic nephropathy accept results which be far better than what have be transport out in the one-time with ARBs in advanced diabetic nephropathy (IDNT,RENAAL). After 5 years the obstacle of renal function (GFR) was comparable to what is expected with mortgage age. This is best encouraging and signify that loss of renal function have been halt." Current US and European hypertension guidelines stipulate on most straightforward queue disbursement of ARBs and ACE inhibitors for hypertensive patients with type 2 diabetic nephropathy.6,7 Various studies have shown that effective cordon of the renin-angiotensin-aldosterone regulations (RAAS) can dwindle renal hamper by mechanism ahead of those of blood pressure dominate alone. For ACE-inhibitors, the evidence for renoprotection self-directed of blood pressure control derive chiefly from observations in patients with type 1 diabetes.2 In type 2 diabetes, trial evidence for renoprotection is immensely soon stronger with ARBs which have prove to be more effective than other classes of antihypertensives in continuing the progression of kidney disease in patients with microalbuminuria or proteinuria.8-11 A secret code of studies of telmisartan (Micardis®/Pritor®) in microalbuminuria and proteinuria have already deliver encouraging results.12-17 DETAIL is the first of five major trial seek the renoprotective benefits of telmisartan which features cut off of the ongoing PROTECTIONTM (Programme of Research tO show Telmisartan End-organ proteCTION) study plan.18 PROTECTION involve beyond 6,500 patients from 32 country unanimous.
