ABSTRACT
Low dose oral minoxidil (LDOM) is an efficacious and safe treatment for alopecia, however, a notable side effect is hypertrichosis. Spironolactone, known for treating hirsutism, is also used off-label for the treatment of certain forms of alopecia and may reduce LDOM-induced hypertrichosis. We performed a retrospective review of 54 patients seen at NYU Langone Health and compared hypertrichosis rates in female alopecia patients on LDOM monotherapy versus those on combination therapy with spironolactone. Among 54 patients, 37 received LDOM alone and 17 received the combination. Hypertrichosis developed in 33.3% of patients, with lower rates in the combination group (17.6% vs. 40.5% for monotherapy). Although not statistically significant, the trend suggests spironolactone may mitigate hypertrichosis. The study highlights the potential of combination therapy to address hypertrichosis and calls for larger studies to confirm these findings.

Acne vulgaris is prevalent among adolescents and adults worldwide and can significantly impact patients' quality of life. Steroidal molecules, including oral and intralesional corticosteroids, combined oral contraceptives (COCs), oral spironolactone, and topical clascoterone, are an important part of the acne treatment armamentarium. The recommended use, mechanism of action, and available evidence supporting the use of steroids for acne treatment are reviewed, and differences in acne clinical presentation and treatment approaches based on patient characteristics relevant to the selection of an appropriate steroid are also discussed. Steroid-based approaches target the systemic or local hormones (ie, testosterone and androgens) and inflammation that contribute to acne pathogenesis. Oral corticosteroids are primarily used as a short-term adjunctive therapy early in treatment, whereas intralesional corticosteroid injections are used for individual acne lesions. COCs and oral spironolactone are limited to female patients who wish to avoid pregnancy. Topical clascoterone can be used by female and male patients 12 years of age and older. Patients' characteristics (including age and patients with darker skin color) and preferences for the route of administration can impact treatment response and adherence, respectively. Overall, healthcare providers must be aware of the differences among steroidal acne treatments and use shared decision-making to select the optimal therapy.

Objective: While the role of aldosterone in bone metabolism is well established, the specific effects of the widely used aldosterone antagonist, spironolactone, on bone health are not fully understood. This study aimed to investigate the effects of spironolactone on osteoporosis and future fracture risk in middle-aged and elderly hypertensive patients, revealing its potential benefits for bone health. Methods: Propensity score matching was employed in this study to create matched groups of spironolactone users and non-users at a 1:4 ratio. We investigated the association between spironolactone use and the risk of osteoporosis using multivariate logistic regression analysis. Furthermore, we conducted multivariate linear regression analysis to explore the relationship between cumulative dosage and the FRAX score. Subgroup analysis was also performed to assess the effects under different stratification conditions. Results: In both pre-match and post-match analyses, multivariable logistic regression revealed a significant reduction in the risk of osteoporosis in the spironolactone usage group (pre-match: odds ratios [OR] 0.406, 95% confidence interval [CI], 0.280-0.588; post-match: OR 0.385, 95% CI, 0.259-0.571). Furthermore, post-match multivariable linear regression demonstrated a clear negative correlation between cumulative spironolactone dosage and the FRAX score. Subgroup analyses consistently supported these findings. Conclusion: This study offers evidence supporting the significant positive impact of the antihypertensive drug spironolactone on bone health, resulting in a substantial reduction in the risk of osteoporosis and future fractures in hypertensive patients. Future research should consider conducting large-scale, multicenter, randomized controlled trials to further investigate the long-term effects of spironolactone on bone health in hypertensive patients.

BACKGROUND: Female-pattern hair loss (FPHL) is characterized by decreased scalp hair density, thinning of hair shafts, and progressive miniaturization of hair follicles. OBJECTIVE: To compare the safety and efficacy of spironolactone versus bicalutamide in female pattern hair loss [FPHL]. METHODS: The study design was retrospective, and all eligible females aged between 18 years and 50 years with FPHL were included. We identified 120 patients from our database who fulfilled the inclusion and exclusion criteria, and patients were then categorized into two groups, Group A comprising patients who were taking 100 mg of spironolactone once daily and Group B comprising patients who were taking 50 mg of bicalutamide once daily along with topical minoxidil 2% in both groups. Patient were analysed at approximately at 24 weeks from the commencement of the treatment. RESULTS: Mean reduction in hair loss severity score on Sinclair scale was 19.51% in spironolactone group compared to 28.20% in bicalutamide group at 24 weeks, which was statistically significant. On global photographic assessment, marked improvement was seen in bicalutamide group compared to spironolactone group (p = 0.139). CONCLUSIONS: Our study, though limited by its retrospective design and small sample size, showed that bicalutamide has greater efficacy and better safety profile in comparison to spironolactone in the treatment of FPHL.

INTRODUCTION: Several randomized controlled trials (RCTs) have examined mineralocorticoid receptor antagonists (MRAs) in heart failure (HF) with reduced ejection fraction (HFrEF). This systematic review and network meta-analysis (NMA) evaluated the comparative efficacy and safety of MRAs in HFrEF. MATERIALS AND METHODS: MEDLINE(Pubmed), Scopus, Cochrane and ClinicalTrials.gov were searched until April 8, 2024 for RCTs examining the efficacy and/or safety of MRAs in HFrEF. Double-independent study selection, extraction and quality assessment were performed. Random-effects frequentist NMA models were used. Evidence certainty was assessed via Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Totally, 32 RCTs (15685 patients) were analyzed. Eplerenone ranked above spironolactone in all-cause mortality (hazard ratio {HR}=0.78, 95% confidence interval {CI} [0.66,0.91], GRADE:"Moderate"), cardiovascular death (HR=0.74, 95%CI [0.53, 1.04], GRADE:"Low") and in all safety outcomes. Spironolactone was superior to eplerenone in the composite of cardiovascular death or hospitalization (HR=0.67, 95%CI [0.50,0.89], GRADE:"Moderate"), HF hospitalization (HR=0.61, 95%CI [0.43,0.86], GRADE:"Moderate"), all-cause hospitalization (HR=0.51, 95%CI [0.26,0.98], GRADE:"Moderate") and cardiovascular hospitalization (HR=0.56, 95%CI [0.37,0.84], GRADE:"Moderate"). Canrenone ranked first in all-cause mortality, the composite outcome and HF hospitalization. Finerenone ranked first in hyperkalemia (risk ratio [RR]=1.56, 95%CI [0.89,2.74], GRADE:"Moderate"), renal injury (RR=0.56, 95%CI [0.24,1.29]), any adverse event (RR=0.84, 95%CI [0.75,0.94], GRADE:"Moderate"), treatment discontinuation (RR=0.89, 95%CI [0.64,1.23]) and hypotension (RR=1.06, 95%CI [0.12,9.41]). CONCLUSIONS: MRAs are effective in HFrEF with certain safety disparities. Spironolactone and eplerenone exhibited similar efficacy, however, eplerenone demonstrated superior safety. Finerenone was the safest MRA, while canrenone exhibited considerable efficacy, nonetheless, evidence for these MRAs were scarce.

PURPOSE: The correlation between spironolactone usage and cancer risk has sparked interest. The objective of this study is to examine the association between spironolactone use and the incidence of urinary tract cancer in the general population. METHODS: We conducted a matched population-based cohort study. The study population was obtained from the Taiwan National Health Insurance Research Database (TNHIRD) during the period from 2000 to 2016. The multivariate Cox proportional hazard model was performed to examine the impact of spironolactone use on the risk of urinary tract cancer. A total of 8,608 individuals exposed to spironolactone were exact matched by 1:1 ratio with unexposed controls on factors including age, gender, comorbidities, CCI scores and socioeconomic status. The incidences of urinary tract cancer, including prostate, renal and bladder cancer, were estimated in both spironolactone exposed and non-exposed cohorts. RESULTS: After adjusting for confounding variables, the multivariate Cox regression analysis showed no significant association between spironolactone exposure and urinary tract cancer incidence, including bladder (adjusted hazard ratio [aHR] = 1.19, 95% confidence interval [CI] = 0.72-1.96, p = 0.50), renal (aHR = 1.75, 95% CI = 0.99-3.07, p = 0.053), and prostate cancer (aHR = 0.67, 95% CI = 0.43-1.04, p = 0.07). When the population was stratified into low (cumulative dose < = 29,300 mg) and high (cumulative dose >29,300 mg) dose of spironolactone, only high dose of spironolactone use was significantly associated with a reduced risk of prostate cancer (aHR = 0.45, 95% CI = 0.23-0.89, p = 0.02), while being associated with an elevated risk of renal cancer (aHR = 2.09, 95% CI = 1.07-4.08, p = 0.03). However, no clear cumulative dose-response relationship was observed in theses associations. CONCLUSIONS: High cumulative dose of spironolactone may be potentially associated with a decreased incidence of prostate cancer and an increased incidence of renal cancer, while no significant association was observed with bladder cancer incidence. However, given the lack of support from the dose-response pattern, the available evidence is inconclusive to establish a definitive association between spironolactone use and urinary tract cancer.

BACKGROUND: The effectiveness and safety of mineralocorticoid receptor antagonists (MRA) in acute heart failure (HF) is uncertain. We sought to describe the prescription of spironolactone during acute HF and whether early treatment is effective and safe in a real-world setting. METHODS: We performed a retrospective cohort study of adult (≥18 years) nonpregnant patients hospitalized with new-onset HF with reduced ejection fraction (HFrEF, defined by ejection fraction ≤40%) within 15 Kaiser Permanente Southern California medical centers between 2016 and 2021. Early treatment was defined by spironolactone prescription at discharge. The primary effectiveness outcome was a composite of HF readmission or all-cause mortality at 180 days. Safety outcomes were hypotension and hyperkalemia at 90 days. RESULTS: Among 2318 HFrEF patients, 368 (15.9%) were treated with spironolactone at discharge. After 1:2 propensity score matching, 354 early treatment and 708 delayed/no treatment patients were included in the analysis. The median age was 63 (IQR: 52-74) years; 61.6% were male, and 38.6% were White. By 90 days, ~20% had crossed over in the two groups. Early treatment was not associated with the composite outcome at 180 days (HR [95% CI]: 0.81 [0.56-1.17]), but a trend towards benefit by 365 days that did not reach statistical significance (0.78 [0.58-1.06]). Early treatment was also associated with hyperkalemia (subdistribution HR [95% CI]: 2.33 [1.30-4.18]) but not hypotension (0.93 [0.51-1.72]). CONCLUSIONS: Early treatment with spironolactone at discharge for new-onset HFrEF in a real-world setting did not reduce the risk of HF readmission or mortality in the first year after discharge. The risk of hyperkalemia was increased.

Acne in adult females is triggered mainly by hormones. Doxycycline is a reference treatment in acne. Spironolactone targets the androgen receptor of sebaceous glands and is prescribed off-label for female adult acne. This multicentre, controlled, randomized, double-blind prospective and parallel study assessed the efficacy of spironolactone compared with doxycycline in adult female acne. A total of 133 women with moderate acne were randomized to receive treatment with: (i) doxycycline and benzoyl peroxide for 3 months followed by a 3-month treatment with its placebo and benzoyl peroxide, or (ii) spironolactone and benzoyl peroxide for 6 months. Successfully treated patients continued with benzoyl peroxide or spironolactone alone for a further 6 months. Primary endpoints were treatment success at month 4 and month 6 with the AFAST score. At all visits, the ECLA score, lesion counts, local and systemic safety and quality of life were assessed. Spironolactone performed better at month 4 and showed a statistically significant better treatment success after 6 months than doxycycline (p = 0.007). Spironolactone was 1.37-times and 2.87-times more successful compared with doxycycline at respective time-points. AFAST and ECLA scores, as well as lesion counts always improved more with spironolactone. Patients' quality of life was better with spironolactone at month 4 and month 6. Spironolactone was very well tolerated. This is the first study to show that, in female adults with moderate acne, treatment with spironolactone is significantly more successful than doxycycline and very well tolerated.

Mineralocorticoid receptor stimulation by aldosterone can cause various cardiovascular and renal disease complications. Finerenone is a new oral nonsteroidal mineralocorticoid receptor antagonist that has been approved for clinical use by the Federal Drug Aministration, and has been shown in clinical trials to reduce the risk of sustained estimated glomerular filtration rate decline, end-stage renal disease, nonfatal myocardial infarction, hospitalization for heart failure and cardiovascular death in adult patients with chronic kidney disease associated with type 2 diabetes. The drug has also been shown to have fewer side effects than the steroidal mineralocorticoid receptor antagonists like spironolactone and eplerenone. In this review article, the authors will discuss the clinical pharmacology of finerenone, its clinical application and the additional studies that are now underway to further assess the efficacy of the drug in diabetic patients having cardiac and renal disease.

INTRODUCTION: Androgenic alopecia (AGA) is the most common cause of hair loss in women, affecting their quality of life. The present study was conducted with the aim of comparing the combined effect of topical minoxidil and oral spironolactone with the combined effect of topical minoxidil and oral finasteride in women with AGA, female and male hair loss patterns. METHOD: This clinical study was performed on 60 women suffering from AGA. The patients were divided into two groups receiving spironolactone 100 mg/day and finasteride 5 mg/day. In addition, a 2% minoxidil solution was used in all patients in addition to treatment with finasteride or spironolactone. At 2 months after initiation and at the end of treatment, patients were evaluated using the Ludwig/Norwood-Hamilton scale and the degree of physician and patient satisfaction. RESULTS: After 2 months, hair density, hair thickness, and hair loss had improved in both groups; however, statistically, there was no significant difference between the two groups with respect to these parameters (p > 0.05). After 4 months, a significant difference was found between the two groups in terms of treatment response (physician satisfaction), hair density, and hair loss severity. So that, the drugs used were ineffective in 6.7% of cases in the minoxidil-spironolactone group and in 16.7% of cases in the minoxidil-finasteride group. In addition, 43.3% of cases in the minoxidil-spironolactone group and 53% in the minoxidil-finasteride group responded well to treatment. The treatment effect was excellent in 56.7% and 0% of the mentioned groups, respectively, and the mentioned difference was statistically significant (p: 0.01). The response to treatment in female pattern hair loss (FPHL) was not statistically significant (p: 0.52), but there was a significant difference in the response to both treatments in male pattern hair loss (MPHL; p: 0.007). In terms of patient satisfaction, minoxidil-spironolactone treatment was significantly better than minoxidil-finasteride regarding hair density and severity of hair loss (p: 0.01). Finally, in terms of treatment complications, the patients in two groups did not have any serious adverse effects. CONCLUSION: The combination of minoxidil and spironolactone could be considered a more effective treatment than the combination of minoxidil and finasteride in women with AGA, FPHL, and MPHL.

OBJECTIVE: Spironolactone (SPL) has been used to manage hyperandrogenic manifestations in women with polycystic ovary syndrome (PCOS), but data on the risk of hyperkalemia in this population are scarce. The aim of this study was to evaluate the incidence of hyperkalemia in women with PCOS using SPL in the long term. DESIGN: Single-centre retrospective study. PATIENTS: Inclusion and analysis of 98 treatment periods in 78 women with PCOS (20 of whom were duplicates, returning after treatment interruption for a mean of 38 months) who received SPL for a minimum of 12 months and had at least three measurements of potassium levels over time. MEASUREMENTS: Clinical and hormonal profiles before and during SPL treatment. RESULTS: Mean age was 29.1 (SD: 9.6) years, and body mass index was 32.2 (SD: 8.1) kg/m². Nine patients had diabetes, and 22 had prediabetes. SPL was used in combination with combined oral contraceptive pills in 55 participants and progestin-only pills/long-acting reversible contraception in 28; metformin was added in 35, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers in 15. Median SPL dose was 100 (range: 50-150) mg. A total of 327 serum potassium measurements were obtained (84 pre-exposure and 243 postexposure). Four potassium measurements were above the reference range before exposure and 19 during exposure. All potassium measurements above the reference range during follow-up were classified as mild hyperkalemia (5.1-5.5 mEq/L). CONCLUSIONS: The present findings suggest that women with PCOS, without kidney or heart disease, using SPL combined with hormonal contraception for managing clinical hyperandrogenism have a low incidence of hyperkalemia and well-tolerated minor adverse effects.

To determine the blood pressure independent effects of spironolactone on left atrial (LA) size and function in patients with resistant hypertension (RHTN). Patients with RHTN (n = 36, mean age 55 ± 7) were prospectively recruited. Spironolactone was initiated at 25 mg/day and increased to 50 mg/day after 4 weeks. Other antihypertensives were withdrawn to maintain constant blood pressure. Cardiac magnetic resonance imaging was performed at baseline and after 6 months of spironolactone treatment and changes in LA functional metrics were assessed. LA size and function parameters were improved (p < 0.05) from baseline to month-6: LA volumes indexed to body surface area (LAVI) were reduced (LAVImaximum 41.4 ± 12 vs. 33.2±9.7 mL/m2; LAVIpre-A 32.6 ± 9.8 vs. 25.6 ± 8.1 mL/m2; median LAVIminimum 18.5 [13.9-24.8] vs. 14.1 [10.9-19.2] mL/m2); left atrioventricular coupling index was reduced (28.2 ± 11.5 vs. 22.7 ± 9.2%); LA emptying fractions (LAEF) were increased (median total LAEF 52.4 [48.7-60.3] vs. 55.9 [50.3-61.1] %; active LAEF 40.2 ± 8.6 vs. 43.1 ± 7.8%). LA global longitudinal strain in the active phase was increased (16.3 ± 4.1 vs. 17.8 ± 4.2%). The effect of spironolactone was similar in patients with high (N = 18) and normal (N = 18) aldosterone status (defined by plasma renin activity and 24-h urine aldosterone). Treatment of RHTN with spironolactone is associated with improvements in LA size and function, and atrioventricular coupling, regardless of whether aldosterone levels were normal or high at baseline. This study suggests the need for larger prospective studies examining effects of mineralocorticoid receptor antagonists on atrial function and atrioventricular coupling.

To compare the effectiveness and safety of spironolactone versus lecithin-bound iodine in patients with central serous retinopathy (CSR). Chinese diabetes patients aged>18 years with CSR with persistent increased level of subretinal fluid (SRF) were enrolled. Subjects were randomized to receive either oral lecithin-bound iodine (390µg/kg/day) or oral spironolactone (50mg/day) for 6 months. A total of 200 patients were randomized and completed the study. Compared to spironolactone group, patients treated with lecithin-bound iodine had greater proportion of eye with complete resolution (87% vs 81%, p>0.005). Higher improvement in height of SRF was observed in lecithin-bound iodine-treated patients as compared with Spironolactone-treated patients (91.2[87.5] vs 142.5 [121.1]; p>0.005). However, no statistically significant difference was observed on none of comparisons. Compared to Spironolactone, the patients treated with lecithin-bound iodine had greater improvement in lesion size, central macular thickness and best-corrected visual acuity. However, no statistically significant difference was observed in any of parameter assessed. (p>0.005). The results of the present study suggested that the lecithin-bound iodine was found more effective (nnumerically) than spironolactone in Chinese diabetes patients with CSR.
