Meta-Analysis
Is the newest angiotensin-receptor blocker azilsartan medoxomil more efficacious in lowering blood pressure than the older ones? A systematic review and network meta-analysis.
Angiotensin-receptor blockers are often considered insufficiently efficacious in reducing blood pressure. However, newer angiotensin-receptor blockers may be more effective than the older ones. A network meta-analysis was performed to compare the efficacy of various angiotensin-receptor blockers in reducing office and ambulatory blood pressure in hypertensive patients. Relevant literature was searched from English and Chinese databases for randomized controlled trials involving angiotensin-receptor blockers in hypertension. Efficacy variables included systolic and diastolic blood pressure either in the office or on ambulatory blood pressure monitoring. Absolute blood pressure reductions at 6-12 weeks of treatment and their credible intervals were reported. A total of 34 publications provided adequate data for analysis (n = 14 859). In 28 studies on office systolic blood pressure (n = 12 731), against the common comparator valsartan 80 mg, the differences in systolic blood pressure were in favor of azilsartan medoxomil (20-80 mg), irbesartan (300 mg), olmesartan (20-40 mg), telmisartan (80 mg), and valsartan (160-320 mg), but not candesartan (8-16 mg), losartan (50-100 mg), irbesartan (150 mg), olmesartan (10 mg), and telmisartan (40 mg). The ranking plot shows that azilsartan medoxomil 80 mg had a possibility of 99% being the best in the class. Similar results were observed for office diastolic blood pressure and from 13 studies for 24-hour ambulatory systolic and diastolic blood pressure. In conclusion, angiotensin-receptor blockers had different blood pressure lowering efficacy. The newest angiotensin-receptor blocker azilsartan medoxomil at the dose of 80 mg seemed to be most efficacious in reducing both systolic and diastolic blood pressure in the office and on ambulatory measurement.

Review
OBJECTIVE
To evaluate the efficacy, safety, and clinical role of azilsartan medoxomil, an angiotensin II receptor blocker (ARB) that recently gained Food and Drug Administration approval for lowering of blood pressure (BP) in patients with hypertension.
DATA SOURCES
A systematic review of the literature was performed through August 2011 using MEDLINE, Web of Science, and International Pharmaceutical Abstracts and the key words and MeSH terms azilsartan, azilsartan medoxomil, TAK-491, TAK-536, and Edarbi. Abstracts presented in the last 2 years from the annual meetings of appropriate medical societies were reviewed in addition to a search of clinicaltrials.gov.
STUDY SELECTION AND DATA EXTRACTION
Studies eligible for inclusion were in vitro or in vivo evaluations of azilsartan medoxomil, with no restrictions on patient population or indication. Data related to the patient populations and outcomes of interest were extracted from each publication.
DATA SYNTHESIS
Three trials are available in full publication form with others available only as abstracts. Azilsartan medoxomil 40 mg and 80 mg daily significantly improves both systolic and diastolic BP from baseline compared with placebo, and the 80-mg dose has greater efficacy than other ARBs, including olmesartan 40 mg daily and valsartan 320 mg daily. Improvements in both 24-hour BP using ambulatory monitoring and clinic monitoring have been seen with azilsartan medoxomil as well as a higher proportion of patients reaching the goal level. Additional information shows added BP lowering when azilsartan medoxomil is combined with chlorthalidone. Adverse events are similar with azilsartan medoxomil versus other ARBs and include headache, dizziness, urinary tract infections, and fatigue.
CONCLUSIONS
Azilsartan medoxomil is a safe and effective ARB with a unique pharmacologic profile versus other agents, including slowed angiotensin II type 1 receptor dissociation rates and improved receptor specificity. Studies have shown azilsartan medoxomil 80 mg once daily to reduce BP to a greater extent than valsartan and olmesartan, with similar safety and tolerability.

Angiotensin II receptor blockers (ARBs) are widely used for the management of hypertension in Japan; however, comparative efficacy data within the ARB drug class remain limited. This systematic literature review identified randomized controlled trials (RCT) indexed in PubMed and Ichushi in Japanese patients with hypertension receiving ARB monotherapy (azilsartan, candesartan cilexetil, irbesartan, losartan potassium, olmesartan medoxomil, telmisartan, valsartan) in at least 1 arm. Of 763 RCTs identified, 77 met the eligibility criteria; of which, 37 reported mean change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) from baseline in the office setting and were used to construct the network. A fixed-effects model (FEM) showed the effect of each drug vs. the reference, azilsartan. Using the FEM, the mean (95% credible interval) change from baseline in SBP/DBP for candesartan cilexetil, irbesartan, losartan potassium, olmesartan medoxomil, telmisartan, and valsartan was 3.8 (2.9-4.8)/2.6 (2.0-3.1), 4.8 (2.0-7.5)/3.7 (1.8-5.6), 3.0 (0.8-5.1)/1.9 (0.5-3.3), 3.2 (1.2-5.1)/2.7 (1.3-4.1), 3.2 (0.8-5.6)/2.0 (0.3-3.6), and 3.1 (1.1-5.1)/2.4 (1.1-3.8) mmHg, respectively. The results of this meta-analysis provide evidence that azilsartan has a more favorable efficacy profile than the other ARBs in reducing SBP and DBP.

PURPOSE OF REVIEW
Systematic review of angiotensin-converting enzyme inhibitors (ACE inhibitors) and angiotensin receptor blockers (ARB) in the prophylactic treatment of adults with migraine. To identify gaps in research and provide guidance for future clinical trials.
RECENT FINDINGS
A search was completed using PubMed, MEDLINE, Embase, and the Cochrane Library January 1, 1990 through December 31, 2017. The following are keywords used in the search: migraine, migraine prophylaxis/prevention, renin-angiotensin-aldosterone system, RAAS, ACE inhibitors, angiotensin-converting enzyme inhibitors: quinapril, perindopril, ramipril, captopril, enalapril, lisinopril, benazepril, fosinopril. Angiotensin receptor blockers, ARB, angiotensin II receptor antagonists: candesartan cilexetil, irbesartan, olmesartan, valsartan, losartan, azilsartan medoxomil, telmisartan, and eprosartan. The search included randomized controlled trials (RCT), systemic reviews and open-label studies of ACE inhibitors and ARB for the prevention of migraine attacks in adults 18-70 years old. Of 2461 retrieved articles, 18 included RCT, meta-analysis, systemic reviews, or guidelines published on ACE inhibitors or ARB in the prevention of migraine. Three RCT with telmisartan 80 mg, candesartan 16 mg, and enalapril 10 mg, and two open-label trials with lisinopril 5 mg and ramipril 5 mg found a high number of responders with greater than 50 % reduction in migraine attack frequency when compared to a 4-week baseline period. Candesartan was superior to placebo while telmisartan and enalapril were not. Lipophilic ACE inhibitors and ARBs can be effective prophylactic agents for reduction of migraine frequency in adults. Based on the limited number of published trials and small sample size, they are not recommended as first-line prophylactic agents. However, in populations with co-morbidities such as hypertension, they may be useful as first- or second-line prophylactics. Additional trials following the International Headache Society's guidelines on RCT are warranted.
