Selective Blocker

Background: Certain drugs produce unpredictable responses when used in emergency conditions. These variable outcomes may be harmful or beneficial for the patient. Objective: This study has been conducted to evaluate the pharmacodynamic interaction between angiotensin converting enzyme inhibitor and metoprolol, a selective blocker of β1 receptors. Cardioselective beta blockers are commonly used to treat hypertension, arrhythmias and ischemic heart disease. Method: In this study, 20 healthy male rabbits were selected and divided into two groups. Effective dose of Lisinopril (10 mg/kg) was administered orally via oral feeding, for 9 days. By using Langendroff’s technique, the effects of metoprolol were observed in isolated hearts. Result: The data showed that the effective dose of Lisinopril (10 mg/kg daily orally) increases the inotropic and chronotropic effects of metoprolol significantly (p<0.05). Conclusion: Therefore, lisinopril, an inhibitor of angiotensin converting enzyme may increase the response of cardioselective beta blocker metoprolol in isolated rabbit’s heart.

Patients With Diabetes

Diabetes mellitus as comorbidity is present in 20–25% of patients suffering from high blood pressure. Because simultaneous presence of these two diseases results in a significant increase of cardiovascular risk, various guidelines focus greatly on the anti-hyperintensive treatment of patients with diabetes. Combined drug therapy is usually required to achieve the blood pressure target value of <140/85 mmHg defined for patients with diabetes, which must be based on angiotensin converting enzyme-inhibitors or angiotensin receptor blockers. These can be/must be combined with low dose, primarily thiazid-like diuretics, calcium channel blockers with neutral metabolic effect, and further options include the addition of beta blockers, imidazolin-l-receptor antagonists, or alpha-1-adrenoreceptor blockers. Evidence-based guidelines are obviously present in local practice. Although most of the patients receive angiotensin converting enzyme-inhibitor+indapamid or angiotensin converting enzyme-inhibitor+calcium channel blocker combined therapy with favorable metabolic effects, yet the use of angiotensin converting enzyme-inhibitors containing hidrochlorotiazide having diabetogenic potencial, and angiotensin receptor blocker fixed combinations is still widespread. Similarly, interesting therapeutic practice can be observed with the use of less differentiated beta blockers, where the 3rd generation carvediolol and nebivolol are still in minority. Orv.

420 Background: Prior history of chronic medical conditions and medical treatment exposure has been significantly associated with the development and prognosis of different cancers. Population-based studies reported a reduced cancer-related mortality among patients with pancreatic cancer who were Statin or Metformin users as compared with non-users. We aimed to study the effect of antihypertensive medications on the survival outcome of pancreatic cancer. Methods: Under institutional ethical approval, medical records were reviewed and clinical characteristics at baseline (time of diagnosis) were retrieved. Blood pressure and antihypertensive medications use were documented including Angiotensin Converting Enzyme Inhibitor (ACEI), diuretics, Angiotensin Receptor Blockers (ARBs) and Beta-Blockers (BB). Hazard ratios (HRs) and 95% CIs were calculated by using Cox proportional hazard models with a backward stepwise selection procedure to identify independent prognostic factors for overall survival. Results: A total of 1,204 patients with adenocarcinoma of the pancreas were diagnosed at MD Anderson Cancer center between 1999 and 2009 were identified. The mean age value (± SD) is 61.9± 10 where 58.6% (N=705) were men and 87.5% (N=1,054) were white. The majority of patients were Caucasian (87%). 41.9% had metastatic disease. A total of 639 (53%) patients had chemotherapy with or without radiation. ACEI and diuretics use independently reduced all-cause mortality, ACEI by 24% with HR 0.76 (CI 0.63-0.91), and diuretics by 26% with HR 0.73 (CI 0.60- 0.89). Neither ARBs nor beta blockers use was statistically significant in reducing all-cause mortality (HR.80, CI 0.63 -1.0), BB HR 0.85 (CI 0.7-1.0). Conclusions: Our findings indicate a significant impact of anti-hypertensive medications including ACEI and diuretics on pancreatic cancer outcomes with improved survival in users versus non-users, this effect was independent of the cancer treatment received, tumour histology and site of metastasis. The potential antitumor activities of these agents in pancreatic cancer should be studied further.
