Prescription patterns of angiotensin-converting enzyme inhibitors for various indications: A UK population-based study.

ABSTRACT: AIM:Angiotensin-converting enzyme inhibitors (ACEIs) are widely prescribed for several cardiovascular indications. This study investigated patterns of ACEI use for various indications. METHODS:A descriptive, retrospective population-based study was conducted using data from the UK Clinical Practice Research Datalink. Patients starting ACEIs (2007-2014) were selected and ACEI indications were retrieved from electronically recorded medical records. Stratified by indication, we distinguished between persistent and nonpersistent ACEI use, considering a 6-month interval between two prescription periods as a maximum for persistent use. Five-year persistence rates for various indications were calculated using the Kaplan-Meier method and compared in a log-rank test. Nonpersistent users were subdivided into three groups: (i) stop; (ii) restart; and (iii) switch to an angiotensin II-receptor blocker. Patients who received ACEIs for hypertension who switched to other classes of antihypertensive medications were further investigated. RESULTS:In total, 254?002 ACEI initiators were identified with hypertension (57.6%), myocardial infarction (MI; 4.2%), renal disease (RD; 3.7%), heart failure (HF; 1.5%), combinations of the above (17.2%) or none of the above (15.8%). Five-year persistence rates ranged from 43.2% (RD) to 68.2% (MI; P < 0.0001). RD and HF patients used ACEIs for the shortest time (average 23.6 and 25.0 months, respectively). For the nonpersistent group, the percentage of switchers to angiotensin II-receptor blockers ranged from 27.6% (RD) to 42.2% (MI) and the restarters ranged from 15.0% (HF) to 18.1% (group without indication). CONCLUSIONS:Depending on the indication, there are various rates of ACEI nonpersistence. Patients with RD are most likely to discontinue treatment.

Project description:ImportanceThe renin-angiotensin system has been implicated in mood disorders. Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are among the most commonly used medications, yet their effects on mental health outcomes, particularly suicide, are poorly understood. This study examined the association between suicide and exposure to ACEIs and ARBs. Because of differences in their mode of action, it was speculated that ARBs would be associated with a higher risk of suicide than ACEIs.ObjectiveTo examine the association between suicide and exposure to ARBs compared with ACEIs.Design, setting, and participantsThis population-based nested case-control study of individuals aged 66 years and older used administrative claims databases in Ontario, Canada, from January 1, 1995, to December 31, 2015. Data analysis was performed from January to April 2019. Cases were individuals who died by suicide within 100 days of receiving an ACEI or ARB. The date of death served as the index date. For each case, 4 controls were identified and matched by age (within 1 year), sex, and presence of hypertension and diabetes. All individuals received an ACEI or ARB within 100 days before the index date.ExposuresUse of an ACEI or ARB.Main outcomes and measuresConditional logistic regression was used to estimate odds ratios for the association between suicide and exposure to ARBs compared with ACEIs.ResultsNine hundred sixty-four cases were matched to 3856 controls. The median (interquartile range) age of cases and controls was 76 (70-82) years. Most cases (768 [79.7%]) and controls (3068 [79.6%]) were men. Among cases, 260 (26.0%) were exposed to ARBs, and 704 (18.4%) were exposed to ACEIs. Among controls, 741 (74.0%) were exposed to ARBs, and 3115 (81.6%) were exposed to ACEIs. Compared with ACEI exposure, ARB exposure was associated with higher risk of death by suicide (adjusted odds ratio, 1.63; 95% CI, 1.33-2.00). The findings were consistent in a sensitivity analysis excluding individuals with a history of self-harm (odds ratio, 1.60; 95% CI, 1.29-1.98).Conclusions and relevanceThe use of ARBs may be associated with an increased risk of suicide compared with ACEIs. Preferential use of ACEIs over ARBs should be considered whenever possible, particularly in patients with severe mental health illness.

Project description:The angiotensin-converting enzyme (ACE) is a two-domain dipeptidylcarboxypeptidase, which has a direct involvement in the control of blood pressure by performing the hydrolysis of angiotensin I to produce angiotensin II. At the same time, ACE hydrolyzes other substrates such as the vasodilator peptide bradykinin and the anti-inflammatory peptide N-acetyl-SDKP. In this sense, ACE inhibitors are bioactive substances with potential use as medicinal products for treatment or prevention of hypertension, heart failures, myocardial infarction, and other important diseases. This review examined the most recent literature reporting ACE inhibitors with the help of molecular modeling. The examples exposed here demonstrate that molecular modeling methods, including docking, molecular dynamics (MD) simulations, quantitative structure-activity relationship (QSAR), etc, are essential for a complete structural picture of the mode of action of ACE inhibitors, where molecular docking has a key role. Examples show that too many works identified ACE inhibitory activities of natural peptides and peptides obtained from hydrolysates. In addition, other works report non-peptide compounds extracted from natural sources and synthetic compounds. In all these cases, molecular docking was used to provide explanation of the chemical interactions between inhibitors and the ACE binding sites. For docking applications, most of the examples exposed here do not consider that: (i) ACE has two domains (nACE and cACE) with available X-ray structures, which are relevant for the design of selective inhibitors, and (ii) nACE and cACE binding sites have large dimensions, which leads to non-reliable solutions during docking calculations. In support of the solution of these problems, the structural information found in Protein Data Bank (PDB) was used to perform an interaction fingerprints (IFPs) analysis applied on both nACE and cACE domains. This analysis provides plots that identify the chemical interactions between ligands and both ACE binding sites, which can be used to guide docking experiments in the search of selective natural components or novel drugs. In addition, the use of hydrogen bond constraints in the S2 and S2' subsites of nACE and cACE are suggested to guarantee that docking solutions are reliable.
