AIM OF THE REVIEW The present review aims to analyze the role of calcium-channel blockers, and particularly newer molecules, as first-line therapy for cerebrovascular disease. BACKGROUND Stroke is the leading cause of disability in the general population. Among traditional cardiovascular risk factors, hypertension has a key role in the genesis of both hemorrhagic and ischemic stroke and a direct correlation exists between blood pressure values and the risk of stroke. Moreover, blood pressure reduction has been demonstrated to be the most important route to reduce stroke incidence and recurrence. However, the mere reduction of blood pressure values does not normalize the cardiovascular risk of the hypertensive patient. It is therefore necessary to use drug classes that beyond their blood pressure-lowering effect have also an additional effect in terms of organ protection. Among these, calcium-channel blockers have a crucial profile. Firstly, they are effective in inducing left ventricular hypertrophy regression, with a strength at least equal to that of ACE-inhibitors. Secondly, they have an antithrombotic and an endothelium-protecting effect, mediated by their antioxidant activity. Finally, calcium-channel blockers are the most powerful drugs in preventing vascular remodeling. For these reasons this drug class has probably the strongest antiatherosclerotic effect, and it is the first-choice treatment mainly for cerebrovascular disease. Among different available calcium-channel blockers, the newer ones seem to possess pharmacokinetic characteristics allowing a more homogeneous 24 hours coverage as compared to older molecules, and preliminary data seem to suggest a greater beneficial effect also on left ventricular hypertrophy and lower incidence of side effects. CONCLUSIONS Although blood pressure reduction is the main tool to reduce cerebrovascular risk in hypertensive patients, some drug classes, such as calciumchannel blockers, seem to provide a protective action beyond the mere antihypertensive effect, and represent a key element in the prevention of atherosclerosis.

One of the most common comorbid condition in people over 40 years old is: arterial hypertension (AH) and chronic obstructive pulmonary disease (COPD). The frequency of AH in patients with COPD varies from 6.8 to 76.3%, in average 34.3%. COPD is detected in every fourth patient with hypertension in the age group of 2564 years. The current trend towards an increase in life expectancy and therefore growing pool of elder cohort, will lead to a higher number of patients with comorbid disorders. Diagnosis and treatment of AH and COPD are determined by current clinical recommendations for both nosologies, however, a number of mutual pathophysiological mechanisms lead to a more severe course of these diseases with frequent exacerbations. The choice of antihypertensive therapy in patients with AH in combination with COPD should be given to drugs that can provide an adequate decrease in blood pressure in hypoxic conditions, especially at night and early morning hours, that have prolonged effect or could be prescribed in the evening, and to those that dont worsen bronchial obstruction or exacerbate hypoxia. Patients with AH and COPD should be given recommendations on lifestyle changes, especially smoking cessation. As initial therapy calcium channel blockers, angiotensin receptor blockers or angiotensin-converting enzyme inhibitors should be considered. Calcium channel blockers/renin-angiotensin system blockers should be considered as the first line for combination therapy. Thiazide, thiazide-like diuretics orb1-selective adrenergic blockers could be prescribed in case of insufficient antihypertensive response or depending on different clinical scenarios. Bronchodilators are the baseline therapy in COPD with concomitant AH. According to modern concepts, prescription of combination therapy with different mechanisms of action is the most proven and justified approach, which leads to a decrease in the frequency of exacerbations of COPD and amelioration of the symptoms. The choice of bronchodilator in the case of a COPD and AH combination, should take into account the proven long-term safety regarding the risk of cardiovascular complications. Tiotropium bromide as the monotherapy, including as a liquid inhaler and aclidinium/formoterol, tiotropium/oladeterol as combination therapy showed cardiovascular safety in the long-term studies. The escalation of COPD therapy with the need of inhaled steroids requires careful monitoring of blood pressure and, possibly, a revision of antihypertensive treatment leading to its escalation as well. COPD has many phenotypes requiring different medications, eg.: roflumilast, theophylline, macrolides and mucoactive drugs, that could also require tighter blood pressure control on patients with COPD and AH.

Background: The angiotensin-converting enzyme inhibitors (ACEIs) could improve the symptoms of diabetic nephropathy. Whether the calcium channel blockers (CCBs) could be as effective as ACEIs on treating diabetic nephropathy is controversial. Here, we aimed to compare the efficacy of ACEIs with CCBs on the treatment of diabetic nephropathy by performing a meta-analysis of randomized controlled trials (RCTs). Methods: The Pubmed, Medline, Embase and The Cochrane Database were searched up to July 2017 for eligible randomized clinical trials studies. Effect sizes were summarized as mean difference (MD) or standardized mean difference (SMD) with 95% confidence intervals (P-value<0.05). Results: Seven RCTs involving 430 participants comparing ACEIs with CCBs were included. No benefit was seen in comparative group of ACEIs on systolic blood pressure(SBP) (MD=1.05 mmHg; 95% CI: -0.97 to 3.08, P=0.31), diastolic blood pressure (DBP) (MD= -0.34 mmHg; 95% CI: -1.2 to 0.51, P=0.43), urinary albumin excretion rates (UAER) (MD=1.91μg/min; 95% CI: -10.3 to 14.12, P=0.76), 24-h urine protein (24-UP) (SMD=-0.26; 95%CI: -0.55 to 0.03, P=0.08), glomerular filtration rate (GFR) (SMD=0.01; 95% CI: -0.38 to 0.41, P=0.95). On safety aspect, the risk of adverse reactions between ACEIs group and CCBs group are similar (RR=1.18; 95% CI: 0.61 to 2.28; P=0.61). Conclusion: Both ACEIs and CCBs could improve the BP, UAER, 24h-UP, and GFR of diabetic nephropathy to a similar extent
