Table 2. ARBs may also increase the blood concentration of lithium (Eskalith, Lithobid) and lead to an increase in side effects from lithium. In which clinical situations are angiotensin receptor blockers (ARBs) preferred over angiotensin-converting enzyme (ACE) inhibitors? However, type 2 receptor activation would be expected to have antitumor effects,28–31 although data are somewhat conflicting.27,32 Safety studies in animals have also demonstrated the absence of carcinogenicity with high doses of ARBs.33–39, Some strengths and limitations of our large nationwide cohort study deserve particular mention. We included all ARBs (ATC-code C09CA) and ACE-inhibitors (C09AA) in use in Denmark, including combinations with thiazide diuretics (C09DA and C09BA, respectively): losartan, eprosartan, valsartan, irbesartan, candesartan, telmisartan, and olmesartan; and captopril, enalapril, lisinopril, perindopril, ramipril, quinapril, benazepril, fosinopril, trandolapril, and moexipril. This site uses cookies. 1-800-242-8721 Clinicians can continue to prescribe ARBs without concern about an excess risk of cancer. Tel: +39 02 55033592, Email: Search for other works by this author on: SARS-CoV2: should inhibitors of the renin–angiotensin system be withdrawn in patients with COVID-19? In these analyses, 365 defined daily doses were defined as equivalent to 1 year, and the cumulative received doses were counted starting after the lag period. In contrast, our study was able to exclude a 3% excess in lung cancer risk (RR, 0.92; 95% CI, 0.82 to 1.02), although an exploratory analysis by histological type found protective associations for small-cell carcinoma and cancer of other/unspecified histological type and an increased risk of adenocarcinoma. were considered as the ACEi/ARB continuation group. This type of language mixing is also called code-switching. There was no significantly increased risk of cancer associated with ARB use after adjustment only for age (RR, 0.93; 95% CI, 0.90 to 0.97) or after adjustment for age, sex, year, socioeconomic class, degree of urbanization, comorbidity, hospitalizations, and use of other antihypertensives (RR, 0.99; 95% CI, 0.95 to 1.03; Table 2). There were no significant associations between ARB use and any of the other 14 subgroups of cancer, including lung cancer (adjusted RR, 0.92; 95% CI, 0.82 to 1.02). We grouped cancers according to anatomic site (International Classification of Diseases codes in Table I in the online-only Data Supplement) and subdivided the respiratory group into lung and nonlung. Kuster et al., on pages 1801–1803. §As captured by the National Patient Registry (documents hospitalizations and outpatient hospital visits). ARB use was significantly associated with a modestly increased risk of male genital cancer (adjusted RR, 1.15; 95% CI, 1.02 to 1.28) and modestly decreased risk of other cancers (ill-defined, secondary, and unspecified sites, and independent multiple primary sites; adjusted RR, 0.78; 95% CI, 0.65 to 0.94) compared with ACE inhibitor use. However, if they later refilled a prescription and fulfilled criteria for use, past users could again be recategorized and contribute person-time to the user group. With the application of a Bonferroni adjustment to the subgroup analyses, a value of P<0.003 would be required for statistical significance. 32 mg. eprosartan (TEVETON) 2 . The other authors report no conflicts. In a nationwide cohort of new users of ARBs and angiotensin-converting enzyme inhibitors ≥35 years of age during 1998 to 2006, we compared incidence rates of all cancer, cancer subgroups by anatomic site, and cancer mortality. Young Arabs tend to use the Arabizi more often, because it’s easier for them to express themselves and avoid mistakes and typos that could develop if they use the classic or Standard Arabic language. In their review, Messerli and colleagues note that the first ACE inhibitor, captopril, came on the market in 1981, while the first ARB, losartan, debuted in 1995. Angiotensin receptors: a new role in cancer? The study was approved by the Danish Data Protection Agency. 7272 Greenville Ave. Copyright © 2021 European Society of Cardiology. A more conservative definition that did not allow gaps between prescriptions, thereby probably limiting analyses to those with more consistent drug exposure, yielded results very similar to the main analysis. If SwitchRx has been a useful tool for your practice, you may want to deepen your understanding and update your psychiatric diagnosing, prescribing, and medication counseling skills. Other published observational studies found no significant association between ARBs and melanoma, breast cancer, or renal cell cancer, but had small sample sizes.14–16 Including more than twice the number of studies compared with the Sipahi et al meta-analysis, Bangalore and colleagues25 recently analyzed pooled data from 21 ARB trials and found no evidence of increased risk of cancer on aggregate associated with ARB use compared with comparator drugs or placebo (odds ratio, 1.01; 95% CI, 0.93 to 1.09; fixed-effects model). We also performed exploratory analyses of lung cancer by histological type: small-cell carcinoma, adenocarcinoma, squamous cell carcinoma, and other/unspecified types. ARB use was not significantly associated with increased risk of incident cancer overall (crude RR, 0.89; 95% CI, 0.85 to 0.92) compared with ACE inhibitor use (Table 2). Angiotensin II receptor blockers (ARBs) are also used to prevent diabetes and reduce the risk of stroke in patients with high blood pressure and an enlarged heart, and they may also prevent the recurrence of atrial fibrillation. We used new users of ACE inhibitors as the comparison group. Relation between drug treatment and cancer in hypertensives in the Swedish Trial in Old Patients With Hypertension 2: a 5-year, prospective, randomised, controlled trial, Angiotensin-converting enzyme inhibitors, calcium channel blockers, and breast cancer. Medical expenditures for hypertensive disorders during pregnancy that resulted in a live birth among privately insured women. Which one is best? Variations in compliance, persistence, and switching behavior were detected between specific ACE inhibitors, but not between specific ARBs. Association between use of angiotensin receptor blockers (ARBs) and risk of incident cancer by anatomic site compared with use of angiotensin-converting enzyme (ACE) inhibitors in a nationwide cohort in Denmark, 1998 to 2006. Thus, each participant could contribute several distinct use and past use episodes that, when added together, represented this participant's total person-time of use and past use, respectively. A limitation, however, is that nonadherence to the dispensed drugs would bias results toward the null if one of the drugs were associated with cancer. Using individual-level data from registries in Denmark, including, for example, information on filled drug prescriptions and cancer diagnoses, we conducted a nationwide cohort study to compare the rates of incident cancer among users of ARBs and angiotensin-converting enzyme inhibitors. between. Customer Service Our finding of no significant association between ARBs and cancer contrasts with that of a recently published meta-analysis of randomized trials by Sipahi et al,4 who found a modestly increased risk of new cancer among patients treated with ARBs (RR, 1.08; 95% CI, 1.01 to 1.15) compared with placebo or comparator drugs. January 2012; American Journal of Pharmacy Benefits 4(4):e81-e87; Authors: Khalid M Kamal. We also analyzed cancer risk according to total duration of ARB use (estimated by cumulative received defined daily doses) compared with the overall risk associated with ACE inhibitor use. Secondary outcomes included cancer subgroups by anatomic site (including a specific analysis of lung cancer because of previous findings4) and specific ARBs, analyses by sex, and cancer mortality. A dose equivalency between enalapril:captopril of 1:7.5 is suggested for the treatment of hypertension. The possibility that our primary comparison group, ACE inhibitors, might be associated with an increased risk of cancer, thereby obscuring a risk associated with ARBs, is not supported by previous data.7–11. Single-cell RNA-seq data analysis on the receptor ACE2 expression reveals the potential risk of different human organs vulnerable to 2019-nCoV infection. Corresponding author. Users of ARBs or ACE inhibitors who subsequently stopped treatment were recategorized to a distinct group of patients—past users—and contributed person-time to this group from the day the maximum gap time after a prescription was exceeded. Furthermore, because risk of prostate cancer did not appear to increase with increasing duration of exposure, biological plausibility of this association is less likely. Search Results for switching-between-different-arbs-in-patients-with-controlled-bp Results for " We used a relatively liberal definition of drug use, allowing up to 50% gaps between prescriptions. Figure 3. This retrospective data-base analysis study was conducted to compare mainte-nance of BP control in patients who continue olmesartan monotherapy with patients who switch to therapy with another ARB. When other antihypertensives were used as the comparison group, the adjusted RR for the association between ARBs and prostate cancer was 1.18 (95% CI, 0.99 to 1.41). Likewise, exploratory analyses of lung cancer by histological type pointed in disparate directions; these findings require further study. Confidence intervals were narrow, allowing exclusion of a 4% increase in the risk of cancer. The meta-analysis also found an increased risk of lung cancer associated with ARB exposure (RR, 1.25; 95% CI, 1.05 to 1.49). submitted!to!the!graduate!school! §Cancer of ill-defined, secondary, and unspecified sites and independent multiple primary sites. Unauthorized Third, we reanalyzed the association between ARBs and cancer overall using new users of other antihypertensives (β-blockers, calcium channel blockers, and thiazide diuretics) as the comparison group; ARB use was not associated with cancer (adjusted RR, 0.96; 95% CI, 0.90 to 1.02). Just register or login to get full access to our switching tools. The primary objective of this study was to evaluate BP control after switching of ARB therapy in patients … 4. Applying a Poisson regression model (log-linear regression of the counts of cancer using the logarithm of the follow-up time as offset), we estimated the RR for incident cancer or cancer mortality comparing ARB and ACE inhibitor users (SAS version 9.1). Michele M Ciulla, Switching to another antihypertensive effective drug when using ACEIs/ARBs to treat arterial hypertension during COVID-19, European Heart Journal, Volume 41, Issue 19, 14 May 2020, Page 1856, https://doi.org/10.1093/eurheartj/ehaa331. Local Info 40 mg. 80 mg. valsartan (DIOVAN) 1 . This article is published and distributed under the terms of the Oxford University Press, Standard Journals Publication Model (, Risk stratification and treatment of acute and chronic coronary syndromes: focus on angina without obstructive coronary arteries, refractory angina, lipids, and clonal haematopoiesis. Furthermore, although the angiotensin receptor system is involved in the process of carcinogenesis, experimental data point, if anything, toward beneficial effects of angiotensin signaling inhibition. Switching from intravenous (IV) to oral (PO) therapy as soon as patients are clinically stable can reduce the length of hospitalization and lower associated costs. Spatially arranged stepwise nanocavity pixels are employed to accurately control the amplitude and phase of light, enabling the generation of high-quality color prints and holograms. Conclusions: Although residual confounding and indication bias cannot be ruled out, this study showed that compliance, persistence, and switching behavior varied between specific ACE inhibitors but not between specific ARBs. Furthermore, we did not detect increased risk associated with increasing exposure time; this analysis included a subgroup with >5 years of cumulative exposure (RR, 1.01; 95% CI, 0.94 to 1.08). 80 mg. 160 mg … Variations in compliance, persistence, and switching behavior were detected between specific ACE inhibitors, but not between specific ARBs. organization. ‡The χ2 test for categorical variables and t test for continuous variables. Adjusted RRs for the association between ARB use and cancer were similar in men and women (Table 2). Cancer risk did not increase with increasing duration of ARB exposure (increase in rate ratio per year, 0.99; 95% confidence interval, 0.99 to 1.00,) and was similar across individual ARBs. (Micromedex Healthcare series, Vol 119) 2: Ramipril 5-10mg daily is considered equivalent to Captopril 50mg bd for the treatment of hypertension (Micromedex Healthcare series, Vol 119) Monitoring requirements when switching ACE-inhibitors The adjusted RRs for ARB use were 1.13 (95% CI, 1.00 to 1.26) for prostate cancer and 1.64 (95% CI, 0.93 to 2.89) for nonprostate cancer. Testimonials. In a separate group of patients treated with ARBs other than LOS (n = 82), a significant BP reduction was observed, but no change in SUA or FEUA was observed. A design that compares initiators of 2 drugs with shared indications has advantages over a design that uses nonusers as a comparison group, reducing the potential for immortal time bias and balancing the treatment groups with regard to patient characteristics not measured in the available register data,40 in our case, for example, smoking, physical activity, and dietary habits. If the second prescription was filled during the lag period, participants did not contribute person-time until after the end of the lag period.

Hudson (1980) distinguished between code switching, code mixing, and borrowing in his section on the mixture of varieties. structural!constraints!! On the other hand, the body of experimental data favors possible beneficial effects of ARBs, including inhibition of tumor growth, angiogenesis, and metastasis in cancer models.12,13, The trials included in the meta-analysis were not designed to investigate cancer as a primary outcome, and the meta-analysis lacked individual-level data, which precluded time-to-event analyses.4 Only 3 small observational studies have examined the association between ARBs and specific cancers, finding no significant risk of melanoma, breast cancer, or renal cancer.14–16. ARB use was not associated with increased risk of cancer mortality compared with ACE inhibitor use (adjusted RR, 0.77; 95% CI, 0.72 to 0.82). The primary outcome measure was risk of incident cancer overall in new users of ARBs compared with new users of ACE inhibitors. By continuing to browse this site you are agreeing to our use of cookies. Risk of incident cancer according to duration of angiotensin receptor blocker (ARB) use compared with any angiotensin-converting enzyme inhibitor use in a nationwide cohort in Denmark, 1998 to 2006. He believes that code-switching is “the inevitable consequence of bilingualism” that leads speakers to choose a language which the other person can understand”. In a nationwide registry-based cohort in Denmark, we evaluated the hypothesis that ARB use is associated with incident cancer in a comparison of new users of ARBs and ACE inhibitors. *Adjusted for calendar year, age in 5-year intervals, sex, socioeconomic class, degree of urbanization, number of hospitalizations in the previous 3 years, Charlson comorbidity index, and use of other antihypertensives (β-blockers, thiazides, and calcium channel blockers). Second, the lag period from first prescription to start of follow-up was redefined as 3 years. In exploratory analyses of lung cancer by histological type, adjusted RRs were 0.80 (95% CI, 0.65 to 0.99) for small-cell carcinoma (n=128 among ARB users), 1.24 (95% CI, 1.01 to 1.52) for adenocarcinoma (n=173), 0.86 (95% CI, 0.67 to 1.12) for squamous cell carcinoma (n=87), and 0.80 (95% CI, 0.65 to 0.98) for other/unspecified types (n=136). Figure 2. Results were similar when ARBs were compared with other antihypertensive drugs in a sensitivity analysis. Participants were censored at the date of a first diagnosis of cancer, end of follow-up (December 31, 2006), death, disappearance, or emigration, whichever occurred first. Switch the patient to the fully covered ARB at a therapeutically appropriate dose as shown below. So, we’re now choosing between losartan, olmesartan, and telmisartan. Mineralocorticoid Receptor Antagonists in CKD: In Need of a Few Large Trials. In planned sensitivity analyses, we first used an alternative exposure definition; ARB exposure was not associated with cancer overall when we used a conservative definition of ARB and ACE inhibitor use that did not allow any gap between prescriptions (adjusted RR, 1.00; 95% CI, 0.95 to 1.05).
