This paper presents the results obtained after studying the thermal stability and decomposition kinetics of perindopril erbumine as a pure active pharmaceutical ingredient as well as a solid pharmaceutical formulation containing the same active pharmaceutical ingredient (API). Since no data were found in the literature regarding the spectroscopic description, thermal behavior, or decomposition kinetics of perindopril, our goal was the evaluation of the compatibility of this antihypertensive agent with the excipients in the tablet under ambient conditions and to study the effect of thermal treatment on the stability of perindopril erbumine...

The surge in arterial pressure during arousal in the waking period is thought to be largely due to activation of the sympathetic nervous system. In this study we compared in SHR the effects of chronic administration of the centrally acting sympatholytic agent rilmenidine with an angiotensin converting enzyme inhibitor perindopril on the rate of rise and power of the surge in mean arterial pressure (MAP) that occurs with arousal associated with the onset of night. Recordings were made using radiotelemetry in 17 adult SHR before and after treatment with rilmenidine (2mg/kg/day), perindopril (1mg/kg/day) or vehicle in the drinking water for 2 weeks...

BACKGROUND: Obstructive sleep apnoea (OSA) is an important cause of secondary hypertension. Nocturnal hypertension is particularly prevalent in OSA and is a strong predictor of cardiovascular mortality. Studies in patients with essential hypertension have suggested that nocturnal administration of antihypertensives improves nocturnal blood pressure (BP) without elevating daytime BP. We evaluated the efficacy of this technique in patients with OSA with stage I/II hypertension, both before and after the addition of CPAP...

The proline analogue (2S,3aS,7aS)-octahydroindole-2-carboxylic acid (Oic) has been previously applied as a proline substitute in pharmocologically active peptides and as a structural component of the antihypertensive drug Perindopril. Herein, we describe the formation of an oligoproline structure by an Oic oligomer. A series of Oic oligomers were investigated to show the structural and energetic contribution of appended residues to the structure. NMR investigation of these oligomers revealed an all-trans amide bond structure, and we provide evidence that a cascade-like mechanism is responsible for the all-trans folding cooperativity...

Purpose The primary toxicity of trastuzumab therapy for human epidermal growth factor receptor 2-overexpressing (HER2-positive) breast cancer is dose-independent cardiac dysfunction. Angiotensin-converting enzyme inhibitors and β-blockers are recommended first-line agents for heart failure. We hypothesized that angiotensin-converting enzyme inhibitors and β-blockers could prevent trastuzumab-related cardiotoxicity. Patients and Methods In this double-blinded, placebo-controlled trial, patients with HER2-positive early breast cancer were randomly assigned to receive treatment with perindopril, bisoprolol, or placebo (1:1:1) for the duration of trastuzumab adjuvant therapy...

BACKGROUND AND OBJECTIVE: Blood pressure (BP) control in hypertensive patients remains poor worldwide, particularly in high-risk patients with hypertension and diabetes. Guidelines recommend that such patients receive prompt pharmacological therapy at maximal doses to rapidly control BP. We aimed to evaluate efficacy and safety of single-pill combination (SPC) perindopril/indapamide (PER/IND) at full dose (10/2.5 mg) in hypertensive patients, including diabetics, with BP uncontrolled by previous medication...

We report an electro-nanofluidic membrane for tunable, ultra-low power drug delivery employing an ionic field effect transistor. Therapeutic release from a drug reservoir was successfully modulated, with high energy efficiency, by actively adjusting the surface charge of slit-nanochannels 50, 110, and 160 nm in size, by the polarization of a buried gate electrode and the consequent variation of the electrical double layer in the nanochannel. We demonstrated control over the transport of ionic species, including two relevant hypertension drugs, atenolol and perindopril, that could benefit from such modulation...

REVIEW

The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in the pathogenesis of hypertension (HTN). Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are first line anti-HTN drug classes that are potent, effective and largely safe. Direct renin inhibitors (DRIs) have shown similar blood pressure (BP) reduction but more side effects. The efficacy of ACEIs and ARBs (for cardiovascular, cerebrovascular and renal protection) has been promoted to extend beyond what could be explained by BP reduction alone...

OBJECTIVE: Antihypertensive medication nonadherence is significant contributor to poor BP control. Patient-related factors (lack of motivation or risk understanding) are important. The aim of PRISMA study was to determine the impact of integrated approach with therapy based on perindopril arginine in the improvement of motivation, adherence to antihypertensive treatment and BP control. DESIGN AND METHOD: 906 (315 male, 56.0 ± 10.6 years) non-adherent (score < 4 in Morisky and Green Test for Measure of Adherence to Therapy) hypertensive patients with planning or action stages of behavior changes (Prochaska and DiClemente model) with uncontrolled hypertension (BP > 140/90 mmHg) were randomly assigned to 2 strategies: integrated approach with therapy based on perindopril arginine with added-on therapy if necessary (G1, n = 755) or routine practice (G2, n = 151)...

OBJECTIVE: The 'legacy effect' of hypertension treatment is where short term treatment with blood pressure (BP) lowering drugs such as angiotensin converting enzyme inhibitors (ACEi) is followed by a persistent reduction in BP, reduced cardiovascular complications and increased lifespan. However, the involvement of epigenetics mechanisms remains unclear. DNA methylation is the binding of a methyl group to DNA which inhibits gene transcription. The aim of this study is to investigate DNA methylation changes after short term treatment with ACEi...

: Age is the most powerful cardiovascular risk factor. Based on a meta-analysis of a million control patients in hypertension trials, the Clinical Trialists Collaboration has estimated that doubling of major cardiac and stroke events occurs with age increments of < 10 years (1). Data from the ACCOMPLISH trial, which will be presented at this ISH meeting for the first time, show that patients aged > 70 (mean: 75.2), compared with those < 70 (mean: 63.7), had a 2.82-fold greater event rate for cardiovascular death and a 2...

INTRODUCTION: We aimed to examine the regulation of aquaporin 1 expression in an angiotensinogen transgenic mouse model, focusing on underlying mechanisms. METHODS: Male transgenic mice overexpressing rat angiotensinogen in their renal proximal tubular cells (RPTCs) and rat immortalised RPTCs stably transfected with rat angiotensinogen cDNA were used. RESULTS: Angiotensinogen-transgenic mice developed hypertension and nephropathy, changes that were either partially or completely attenuated by treatment with losartan or dual renin-angiotensin system blockade (losartan and perindopril), respectively, while hydralazine prevented hypertension but not nephropathy...

BACKGROUND: Apoptosis contributes nephropathy pathogenesis in diabetes. However, its mechanisms still remain unclear. We examined the extent to which the angiotensin-II type 1 receptor blocker (AT1RB) irbesartan and the angiotensin converting enzyme inhibitor (ACEI) perindopril affected the apoptosis-related proteins Bcl-2, Bax, caspase-3, cytochrome-c and Ku70 in streptozotocin (STZ)-diabetic rats. MATERIALS AND METHODS: Animals were divided into five groups of eight each, four of which received STZ (60mg/kg in a single dose, i...

Angiotensin converting enzyme (ACE) converts Angiotensin I to a potent vasoconstrictor angiotensin II (ANG II). ACE inhibitors (ACEIs) are widely used for the management of hypertension. All components of the renin-angiotensin system (RAS) have also been identified in the brain. In addition to cytokines, neuromodulators such as ANG II can induce neuroinflammation. Moreover, in Alzheimer's disease (AD) models, where neuroinflammation occurs and is thought to contribute to the propagation of the disease, increased levels of ANG II and ACE have been detected...

The main Hypertension in the Very Elderly Trial (HYVET) demonstrated a very marked reduction in cardiovascular events by treating hypertensive participants 80 years or older with a low dose, sustained release prescription of indapamide (indapamide SR, 1.5 mg) to which was added a low dose of an angiotensin converting enzyme inhibitor in two-thirds of cases (perindopril 2-4 mg). This report from the ambulatory blood pressure sub-study investigates whether changes in arterial stiffness and ambulatory blood pressure (BP) could both explain the benefits observed in the main trial...
