Between the first and third visits mean BP values (systolic/diastolic) decreased from 158.4 ± 13.6/89.9 ± 8.7 mmHg to 130.0 ± 7.9/77.7 ± 6.3 mmHg (P < 0.001). The magnitude of BP reduction depended on baseline blood pressure levels and total cardiovascular (CV) risk (P < 0.001). Patients with grade 1, 2 and 3 showed a BP reduction of 21.9/10.0 mmHg, 34.4/14.2 mmHg and 51.4/21.2 mmHg, accordingly (P < 0.001). Patients with very high, high, moderate and low added CV risk showed a BP reduction of 35.7/14.9 mmHg, 27.5/12.1 mmHg, 28.6/12.2 mmHg and 14.5/5.8 mmHg respectively (P < 0.001). Adherence to treatment was high: 98.3% of the sample was taking the treatment "every day" or "quite often", while only 15 patients (0.7% of the sample) prematurely discontinued treatment. Study interpretation may be limited by the fact that this is an observational study with no comparator and a short follow-up period.

Despite significant advances in revascularization techniques and medical therapy, there remains a significant population of patients who continue to have intractable angina symptoms. This review aims to define the patients with refractory angina pectoris (RAP) and to present the therapeutic options currently available for this condition. RAP itself is defined and the pharmacological treatment options other than traditional medical therapies are discussed. The latest therapeutic options for this patient population are extensively reviewed. Among the multitude of pharmacological and non-invasive therapeutic options for patients with RAP, ranolazine is a new drug indicated for the treatment of chronic angina, in combination with amlodipine, beta-blockers or nitrates. Enhanced external counterpulsation has not only been shown to improve symptoms, but also to improve long-term ventricular function in these patients. In randomized trials, neurostimulation has been shown to be effective in reducing angina symptoms. Transmyocardial laser revascularization has emerged as an invasive treatment for RAP over the last two decades. Extracorporeal shockwave myocardial revascularization gene therapy and percutaneous in situ coronary venous arterialization are still under investigation.

The rate of anginal episodes decreased significantly (p = 0.009) with amlodipine treatment compared with placebo and the intake of nitroglycerin tablets showed a similar trend. Peripheral edema was the only adverse event seen more frequently in amlodipine-treated patients. No patient was withdrawn from the double-blind phase of the study because of an adverse event. Patients who completed the double-blind phase as responders to amlodipine or as nonresponders to placebo were offered the option of receiving amlodipine in a long-term, open label extension phase. During the extension, the daily dose of amlodipine was adjusted to 5 or 15 mg if needed and the rate of both anginal episodes and nitroglycerin tablet consumption showed statistically significant decreases between baseline and final assessment.

The counterfeiting of pharmaceuticals has been detected since about 1990 and has alarmingly continued to pick up steam. We have been recently involved in an evaluation program of some of the most commonly prescribed cardiovascular drugs in Africa, for analysing an important number of tablets or capsules obtained from different places in seven African countries. A reversed-phase high-performance liquid chromatography with tandem mass spectrometry method was developed and validated to simultaneously control the identity and the quantity of acenocoumarol, amlodipine, atenolol, captopril, furosemide, hydrochlorothiazide and simvastatin in tablets. Their separation was performed on a Kinetex® C(18) (100 mm × 2.1 mm inside diameter, 2.6 μm) column using a gradient elution of 20 mM ammonium formate buffer and acetonitrile (90:10 10:90 v/v) at a flow rate of 0.5 mL/min. The analytes were detected using electrospray ionisation tandem mass spectrometry in both positive and negative modes with multiple reaction monitoring. Tandem mass spectrometry fragmentation patterns of captopril, furosemide and acenocoumarol, up to now not detailed in the literature, were also studied to assist in the selection of the most relevant transitions towards the objectives. The developed method was validated as per International Conference on Harmonisation guidelines with respect to specificity, linearity, trueness, precision, limits of detection and quantification. It has been successfully applied to the control of oral forms of seven cardiovascular drugs collected in African countries.
Although, LDL-C and triglyceride are reduced after aerobic dance training, they were not any more than without it. Aerobic dance training has favorable effects on LDL-C, triglyceride, and systolic and diastolic BP in individuals with hypertension on a thiazide.

The objective of this study was to compare the effect on ankle edema of adding valsartan (V) or olmesartan (O) to amlodipine (A) in the treatment of hypertension.
The present study evaluated the ability of a Saccharomyces cerevisiae expression system to predict the pharmacokinetic (PK) activity of a calcium channel blocker in patients with distinct cytochrome P450 3A5 (CYP3A5) polymorphisms. The blood pressure lowering activity of amlodipine in 57 hypertensive patients with CYP3A5*1/*1, CYP3A5*1/*3, CYP3A5*4 and CYP3A5*6 polymorphisms was evaluated by the current study. Subsequently, a Saccharomyces cerevisiae expression system for CYP3A5 gene polymorphisms was constructed to examine the PK activity of CYP3A5*1/*1, CYP3A5*4 and CYP3A5*6 polymorphisms. This system was used to predict the PK of amlodipine and was compared with the in vivo data from different gene polymorphism groups. The blood pressure lowering activity of amlodipine in hypertensive patients varied among CYP3A5 polymorphisms. The in vivo results demonstrated that CYP3A5*6 exhibited the highest metabolic rate, followed by CYP3A5*1/*1, CYP3A5*4 and CYP3A5*1/*3. The difference between CYP3A5*6 and CYP3A5*1/*1 was not statistically significant (P=0.5). In accordance with in vivo data, CYP3A5*1/*1 exhibited the highest in vitro metabolic rate, followed by CYP3A5*6 and CYP3A5*4. With the exception of the comparison between CYP3A5*6 and CYP3A5*1/*1, polymorphisms exhibited statistically significant differences compared with CYP3A5*1/*1 (P<0.05). The Saccharomyces cerevisiae expression system may be a cost effective and potentially useful tool for assessing the PK activity of drugs that are metabolized by CYP3A5.
A high number of pills is considered a burden by the patients. This burden increases with the number of pills taken per day.

The study was a prospective, randomized multicenter trial exploring the antihypertensive effect of aliskiren in comparison with amlodipine, a calcium channel blocker, in patients undergoing HD. A total of 83 participants whose blood pressure (BP) had previously been treated with more than one antihypertensive agent and not having achieved the BP goal of <140/90 mmHg were randomly assigned to either aliskiren 150 mg or amlodipine 5 mg as an add-on therapy.

Prescribers may to some extent avoid co-prescription of statins with calcium blockers and fibrates with an increased risk of myopathy. We found no evidence for avoiding co-prescriptions of statins and antibiotics with an increased risk of statin-induced adverse drug reactions. Co-prescription of statins and gemfibrozil is paradoxically associated with a marked increased statin dose, further aggravating the risk for severe myopathy.

A total of 162 transplant recipients were included in the study. The patients were randomized into 3 groups: group 1 received losartan; group II received an angiotensin-converting enzyme inhibitor (captopril), and group III received a calcium channel blocker (amlodipine). All the parameters were recorded at the time of therapy initiation and at 1, 4 and 12 weeks and 12 months thereafter. Graft biopsy before the start and at the end of the study was done to evaluate histopathological progression.

Angiotensin II receptor blockers (ARB) are often co-administered with a calcium channel blocker (CCB) for treating hypertension. In this open-label randomised study, untreated diabetic hypertensive patients were randomised to receive either olmesartan 20 mg/day or candesartan 8 mg/day for 12 weeks. Patients with blood pressure exceeding 130/80 mm Hg received add-on 16 mg/day azelnidipine to ongoing olmesartan (OL group) or 5 mg/day amlodipine to ongoing candesartan (CA group) for 24 weeks. Home-measured and clinic-measured blood pressure decreased in both groups. Fasting blood glucose, haemoglobin A1c (HbA1c) and urinary albumin levels decreased significantly in the OL group but not in the CA group. In conclusion, this study revealed clinically relevant differences between two combinations of an ARB+CCB in diabetic hypertensive patients. Olmesartan and azelnidipine had a more persistent early morning antihypertensive effect and produced greater decreases in heart rate, fasting blood glucose and HbA1c (National Glycohemoglobin Standardization Program values) levels, and microalbuminuria than did candesartan and amlodipine.

Several calcium entry blockers have shown an antiatherosclerotic effect both in vitro and in vivo. The effects are particularly evident against smooth muscle cell migration multiplication, matrix formation, calcium and cholesterol accumulation. Among the new calcium antagonists, isradipine, amlodipine and lacidipine, are promising as antiatherosclerotic agents. Lacidipine is particularly interesting because of its lipophylic structure and accumulation in cell membranes. Lacidipine is structurally related to nifedipine; we observed that lacidipine inhibits three major processes of atherogenesis: cholesteryl ester metabolism in macrophages, proliferation of myocytes, and their migration.

We evaluated the anti-hypertensive and anti-albuminuric effect of the angiotensin receptor blocker telmisartan alone and in combination with torasemide and amlodipine. Patients were hypertensive, both diabetics and non-diabetics with persistent microalbuminuria. Our primary endpoint was a change in microalbuminuria levels, while the secondary endpoints were changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine levels, and glomerular filtration rate.After the 16-week treatment period, the patients significantly reduced microalbuminuria levels (76.4 ± 52.4 μg/min; p < 0.001), SBP (16.4 ± 8.7 mmHg; p < 0.001) and DBP (17.7 ± 5.9 mmHg; p < 0.001). Both diabetics and non-diabetics showed an identical pattern of significance with respect to the whole population. Systolic blood pressure, DBP, and microalbuminuria were significantly reduced as a consequence of therapy, both in diabetics and non-diabetics.

This 8-week, open-label, single-arm trial evaluated the efficacy and tolerability of the combination of amlodipine and valsartan in patients not responding adequately to treatment with amlodipine or felodipine alone. Patients aged > or =18 years with moderate essential hypertension (defined as mean sitting systolic blood pressure [MSSBP] > or =160 and <180 mmHg) were treated for 4 weeks with once-daily amlodipine 5 mg or felodipine 5 mg. At week 4, patients not adequately responding were treated for an additional 4 weeks with once-daily amlodipine 5 mg plus valsartan 160 mg. Of 214 patients treated for 4 weeks with amlodipine 5 mg or felodipine 5 mg, 181 failed to achieve MSSBP <140 mmHg. These non-responders were treated for an additional 4 weeks with amlodipine 5 mg and valsartan 160 mg.
