[Serotoninergic drugs for weight loss. A review of efficacy and cardiovascular safety of lorcaserin]

SIMONYI Gábor

[Complex therapy of obesity consist the medical treatment. Several weight lowering drugs are available in the United States, one of which is 5-HT2c agonist lorcaserin. After failures with former non-selective serotoninergic agents (fenfluramine, dexfenfluramine), there was great anticipation and more questions about the release of lorcaserin, which proved its effectiveness and safety in several phase 3 studies. Lorcaserin is a selective agonist of 5-HT2c receptors, therefore free form adverse effects of former non-selective serotoninergic drugs on valvulopathy or pulmonary hypertension. The results of the recently published CAMELLIATIMI 61 study confirmed the cardiovascular safety of lorcaserin.]

[GLP-1 receptor agonists in the treatment of type 2 diabetes]

WINKLER Gábor

[The glucagon-like peptide (GLP)-1 receptor agonists and somewhat later, the sodium-glucose cotransporter (SGLT) -2 inhibitors have brought new perspectives in the antihyperglycemic treatment of type 2 diabetes. The article overviews clinicopharmacologic characteristics of the GLP-1 receptor agonist group, their glycemic and non-glycemic effects, results of the cardiovascular endpoint studies as well as their place in the recent therapeutic guidelines. It is proven, that both glycemic and weight reducing effect is greater of the long-acting (non-prandial) coumpounds as compared to that of the short acting (prandial) derivates, further, that in studies with cardiovascular endpoints they reduced the relative risk of the composite endpoint of non-fatal myocardial infarct, non-fatal stroke and cardiovascular death. Due to the favolurable glycemic and non-glycemic properties their use is advised already in the early course of type 2 diabetes, as combination of the metformin therapy.]

[Dopamine agonists in Parkinson’s disease therapy - 15 years of experience of the Neurological Clinics from Tîrgu Mureș. A cross-sectional study ]

SZÁSZ József Attila, CONSTANTIN Viorelia, MIHÁLY István, BIRÓ István, PÉTER Csongor, ORBÁN-KIS Károly, SZATMÁRI Szabolcs

[Background and purpose - There is relatively few data regarding the usage of dopaminagonists for the treatment of Parkinson’s disease; furthermore, there are no publications regarding Central- and Eastern-European countries. The aim of the study was to evaluate the use of dopamine agonists as a therapeutic option amongst Parkinson’s disease patients admitted to the Neurological Clinics of Tîrgu Mures during the last 15 years. Methods - In our study we investigated the data of all Parkinson’s patients treated at our clinics between the 1st of January 2003 and the 31st of December 2017. We analyzed the particularities of dopamine agonists’ usage based on the therapeutic recommendations from the final report of these patients. Regarding time since the diagnosis, we divided the patients in two groups: less than or equal to 5 years and more than 5 years. Results - During the studied period a total of 2379 patients with Parkinson’s disease were treated at the Clinics. From the 1237 patients with disease duration under 5 years 665 received dopamine agonists: 120 as monotherapy, 83 together with monoamine oxidase inhibitors and in 234 cases associated with levodopa. The remaining 228 patients were treated with a triple combination of levodopa, dopamine agonists and monoamine oxidase inhibitors. In patients suffering from Parkinson’s disease for more than 5 years, in 364 cases out of 653 a dopamine agonist was part of the therapy. Conclusion - The usage of dopamine agonists was similar to the data presented in other studies. We consider that clinicians treating the disease should, with the necessary prudence, use the available and recommended dopamine agonist with the utmost courage to their maximum therapeutic potential.]

[Antihypertensive effect of rilmenidine focusing on the Hungarian multicenter trial VERITAS]

FARSANG Csaba, FINTA Ervin

[Summary in the antihypertensive therapy, in addition to the RAS-blockers (ACE-inhibitors or ARBs), calcium antagonists and thizid-like diuretics, other antihypertensive drugs with different mechanisms of actions, such as the imidazoline I1 receptor agonists, are beneficially used. Several international and Hungarian studies showed the results of the effects of these agents. Authors emphasize the effects of the VERITAS study showing that in hypertensive patients the imidazoline I1 receptor agonist, rilmenidine significantly decreased the office blood pressure as well as the blood pressure measured by ambulatory blood pressure monitoring (ABPM). The white-coat reaction and left ventricular hypertrophy (LVH) were also decreased. In a separate study involving hypertensive subjects rilmenidine significantly increased baroreflex sensitivity. This effect may contribute - mainly during daytime - to the antihypertensive effect. Authors summarise the most important actions of rilmenidine, and the selected publications on the results of the Hungarian and international investigations.]

[Place of rilmenidine therapy in reducing of sympathetic overactivity]

FINTA Ervin, KUN Edit, SIMONYI Gábor

[The sympathetic nervous system plays an important and widely investigated role in the pathogenesis of the hypertension and its concomitant diseases. Between the several types of antihypertensive drugs which can influence the sympathetic over activity, centrally acting agents, play an important role. Here some special aspects of the imidazoline I1 receptor agonist rilmenidine are reviewed.]

[Deeper analysis of nebivolol effects]

KÉKES Ede

[Author presents the formation of nitric oxide as a largest vasodilator of human endothelium as well as the endothelial dysfunction a result of formation at adrenergic stimulus. He demonstrates in detail the benefits of selective β-1 blocker and β-3 adrenergic agonist nebivolol in the vascular system. This drug has also receptor independent effects. Complex effects of nebivolol causes vasodilation, inhibits oxidative stress and it is capable to neutralize the effects of free oxygen radicals and as a result the endothelial function will be better. Its clinical effects and the less wellknown beneficial properties are listed. The use of drug is discussed especially in hypertensives with smoking, COPD or PAD. The β-3 agonist effect provides positive reactions not only in the adipocytes and the myocardial tissue. but in the skeletal muscle as well: Increase in energy expenditure - as a compensatory mechanism - is increased in obesity and the glucose uptake + storage on skeletal muscle cells are increased in hyperglycemia. The insulin sensitivity will be better, leptin level is decreased, adiponectin level is increased by nebivolol. It is assumed this drug has antidiabetic and anti-obesity effects.]

[Rilmenidin - a versatile combination partner in the treatment of high blood pressure]

KÉKES Ede

[The rilmenidin as an imidazoline agonist drug strongly decreases the central sympathetic activity, release of renine and the RAS activity. Because of these advantageous properties the peripheral vascular resistance falls and the blood pressure is decreased. Today it is excellent tool for combination therapy. Useful especially in stress induced hypertension. The antihypertensive effects of ACE inhibitors sor calcium antagonists are increased by rilmenidine. This drug decreases the insuline resistance, it has a positive effect on the carbohydrate and fat metabolism, because it is useful as a complementary therapy in metabolic syndrome and diabetes mellitus of type II. It is useful in stress induced hypertension, and in menopause as well.]

[The positive additive effect of rosuvastatin on platelet aggregation parameters in patients with cerebrovascular disease]

FEHÉR Gergely

[Statin therapy is the cornerstone of anti-atherosclerotic treatment, and it considered obligatory in the secondary prevention of atherosclerotic diseases. Rosuvastatin is well-known and efficacious lipid-lowering agent and seems to have benefitial antiplatelet efficacy and anti-inflammatory profile. The aim of our study was to determined the antiplatelet effect of 20 mg rosuvastatin (Xeter®, Richter Gedeon Nyrt.) in clopidogrel treated cerebrovascular patients. 20 patients with documented ischaemic cerebrovascular events and on 75 mg clopidogrel daily treatment were included in our study. 20 mg generic rosuvastatin significantly decreased total cholesterol (5.67 vs. 3.99 mmol/l, p<0.05), low-density lipoprotein (3.11 vs. 1.92 mmol/l, p<0.05) and trigliceride levels (1.75 vs. 1.29 mmol/l, p<0.05), and there was a non-significant high-density lipoprotein increasing (1.28 vs. 1.36 mmol/l, p=0.09) and high-sensitive C-reactive protein level decreasing tendency (3.35 vs. 2.99 mg/l, p=0.07). Rosu­vastatin treatment significantly decreased ADP 5 µM (46.15 vs. 31.35%) and collagen 2 mg/ml (68.62 vs. 52.22%) induced platelet aggregation (p<0.05). 20 mg rosuvastatin has a robust antilipaemic profile with benefitial additive effect on agonist induced platelet aggregation.]
