Non-steroidal anti-inflammatory drugs for heavy menstrual bleeding

BACKGROUND

Heavy menstrual bleeding (HMB) is an important cause of ill health in premenopausal women. Although surgery is often used as a treatment, a range of medical therapies are also available. Non-steroidal anti-inflammatory drugs (NSAIDs) reduce prostaglandin levels, which are elevated in women with excessive menstrual bleeding and also may have a beneficial effect on dysmenorrhoea.

OBJECTIVES

To determine the effectiveness, safety and tolerability of NSAIDs in achieving a reduction in menstrual blood loss (MBL) in women of reproductive years with HMB.

SEARCH METHODS

We searched, in April 2019, the Cochrane Gynaecology and Fertility specialised register, Cochrane Central Register of Studies Online (CENTRAL CRSO), MEDLINE, Embase, PsycINFO, the clinical trial registries and reference lists of articles.

SELECTION CRITERIA

The inclusion criteria were randomised comparisons of individual NSAIDs or combined with other medical therapy with each other, placebo or other medical treatments in women with regular heavy periods measured either objectively or subjectively and with no pathological or iatrogenic (treatment-induced) causes for their HMB.

DATA COLLECTION AND ANALYSIS

We identified 19 randomised controlled trials (RCTs) (759 women) that fulfilled the inclusion criteria for this review and two review authors independently extracted data. We estimated odds ratios (ORs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes from the data of nine trials. We described in data tables the results of the remaining seven cross-over trials with data unsuitable for pooling, one trial with skewed data, and one trial with missing variances. One trial had no data available for analysis.

MAIN RESULTS

As a group, NSAIDs were more effective than placebo at reducing HMB but less effective than tranexamic acid, danazol or the levonorgestrel-releasing intrauterine system (LNG IUS). Treatment with danazol caused a shorter duration of menstruation and more adverse events than NSAIDs, but this did not appear to affect the acceptability of treatment, based on trials from 1980 to 1990. However, currently danazol is not a usual or recommended treatment for HMB. There was no clear evidence of difference between NSAIDs and the other treatments (oral luteal progestogen, ethamsylate, an older progesterone-releasing intrauterine system and the oral contraceptive pill (OCP), but most studies were underpowered. There was no evidence of a difference between the individual NSAIDs (naproxen and mefenamic acid) in reducing HMB. The evidence quality ranged from low to moderate, the main limitations being risk of bias and imprecision.

AUTHORS' CONCLUSIONS

NSAIDs reduce HMB when compared with placebo, but are less effective than tranexamic acid, danazol or LNG IUS. However, adverse events are more severe with danazol therapy. In the limited number of small studies suitable for evaluation, there was no clear evidence of a difference in efficacy between NSAIDs and other medical treatments such as oral luteal progestogen, ethamsylate, OCP or the older progesterone-releasing intrauterine system.

Satisfaction and health-related quality of life in women with heavy menstrual bleeding; results from a non-interventional trial of the levonorgestrel-releasing intrauterine system or conventional medical therapy

Purpose

To evaluate the patient satisfaction and health related quality of life (HRQoL) for levonorgestrel-releasing intrauterine system (LNG-IUS) versus conventional medical treatments ([CMTs] combined oral contraceptives, oral progestins, and antifibrinolytics, alone or in combination) in Asian women with heavy menstrual bleeding (HMB).

Patients and methods

A total of 647 patients diagnosed with HMB were recruited to this non-interventional study from the eight participating countries in Asia. Patient satisfaction was recorded at the last visit (at 12 months or premature discontinuation). At each visit (at 3, 6, and 12 months), patients completed the menorrhagia multi-attribute scale (MMAS) to assess HRQoL.

Results

A total of 83.5% of patients on the LNG-IUS were “very satisfied” or at least “satisfied” with the therapeutic effect of HMB treatment, compared with 59.2% of patients with CMTs (P<0.05). The mean (± standard deviation) MMAS score increased from 41.4±24.5 to 87.7±21.4 in the LNG-IUS arm, and from 44.1±24.9 to 73.1±25.3 in the CMTs arm. This increase was significantly higher in patients on the LNG-IUS, as compared with those on CMTs (P<0.05). The improvement in HRQoL in both treatment groups correlated with the body mass index of the patient, with larger improvement obtained in women with a higher body mass index.

Conclusion

The majority of women using the LNG-IUS or CMTs for HMB were satisfied with their treatment, and both treatment modalities were associated with significant improvements in HRQoL over time. The improvement was greater with the LNG-IUS, compared with CMTs.

Non-steroidal anti-inflammatory drugs for heavy menstrual bleeding

BACKGROUND

Heavy menstrual bleeding (HMB) is an important cause of ill health in premenopausal women. Although surgery is often used as a treatment, a range of medical therapies are also available. Non-steroidal anti-inflammatory drugs (NSAIDs) reduce prostaglandin levels, which are elevated in women with excessive menstrual bleeding and also may have a beneficial effect on dysmenorrhoea.

OBJECTIVES

The primary objective of this review was to investigate the effectiveness of NSAIDs in achieving a reduction in menstrual blood loss in women of reproductive years with HMB.

SEARCH METHODS

We searched the Cochrane Menstrual Disorders & Subfertility Group trials register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and CINAHL in July 2012 and reference lists of articles. We also contacted manufacturers and researchers in the field.

SELECTION CRITERIA

The inclusion criteria were randomised comparisons of individual NSAIDs or combined with other medical therapy with either each other, placebo or other medical treatments in women with regular heavy periods measured either objectively or subjectively and with no pathological or iatrogenic (treatment-induced) causes for their heavy menstrual blood loss.

DATA COLLECTION AND ANALYSIS

Eighteen RCTs were identified that fulfilled the inclusion criteria for this review and data were extracted independently. Odds ratios for dichotomous outcomes and weighted mean differences for continuous outcomes were estimated from the data of nine trials. The results of the remaining seven cross-over trials with data unsuitable for pooling, one trial with skewed data and one trial with missing variances were described in data tables.

MAIN RESULTS

As a group, NSAIDs were more effective than placebo at reducing HMB but less effective than either tranexamic acid, danazol or the levonorgestrel-releasing intrauterine system (LNG IUS). Treatment with danazol caused a shorter duration of menstruation and more adverse events than NSAIDs but this did not appear to affect the acceptability of treatment. There were no statistically significant differences between NSAIDs and the other treatments (oral luteal progestogen, ethamsylate, an older progesterone-releasing intrauterine system (Progestasert), oral contraceptive pill (OCC)) but most studies were underpowered. There was no evidence of a difference between the individual NSAIDs (naproxen and mefenamic acid) in reducing HMB.

AUTHORS' CONCLUSIONS

NSAIDs reduce HMB when compared with placebo but are less effective than tranexamic acid, danazol or LNG IUS. However, adverse events are more severe with danazol therapy. In the limited number of small studies suitable for evaluation, no significant difference in efficacy was demonstrated between NSAIDs and other medical treatments such as oral luteal progestogen, ethamsylate, OCC or another type of intrauterine system, Progestasert.

Management of heavy menstrual bleeding in general practice

BACKGROUND

Heavy menstrual bleeding (HMB) is a common symptom that leads women to seek medical treatment. Sources of HMB are variable; patients may present with obvious uterine pathology, systemic disease, or even localized hemostatic dysregulation that defies clinical measurement. Whereas surgical intervention even in the absence of overt pathology had historically been the most common route of treatment for HMB, an expanding therapeutic armamentarium provides greater options and the possibility of maintaining fertility in affected women.

SCOPE

A descriptive literature review was performed to identify relevant articles discussing the management of HMB. The PubMed database was searched using the terms 'heavy menstrual bleeding', 'menorrhagia', 'abnormal uterine bleeding', or 'dysfunctional uterine bleeding' in combination with 'diagnosis', 'treatment', 'management', or 'guidelines'. Results were limited to articles published in English within the past 10 years. Additional statements, consensus documents, and clinical guidelines were located through review of professional society websites.

FINDINGS

For practical purposes, a subjective definition of HMB (i.e., excessive menstrual blood loss that is not tolerated by the patient and adversely affects quality of life) rather than objective measures can be used by the clinician as the basis for further investigation. Standard diagnostic examinations and initiation of therapy are well within the purview of the general practitioner. A wide variety of medical therapy options are available, although few treatments are specifically indicated for the management of HMB. The approval of tranexamic acid in the United States specifically for the treatment of HMB is a recent development that provides practitioners with an effective, noncontraceptive alternative medical therapy. For women without evidence of uterine pathology, invasive/surgical procedures are generally considered as a second-line treatment option.

CONCLUSIONS

Given the breadth of available medical and surgical treatment choices, identifying a suitable therapeutic strategy should be feasible for all patients, even in this highly heterogeneous population.

Reducing Heavy Menstrual Bleeding: Safety and Efficacy of Tranexamic Acid

Menorrhagia or Heavy Menstrual Bleeding (HMB) remains a public health challenge among women in the reproductive age group. Anti-fibrinolytics such as tranexamic acid and epsilon aminocaproic acid, play an important role in the medical management of HMB, as HMB is associated with an increase in local fibrinolysis. Lysteda is a novel oral formulation of tranexamic acid which has recently been approved by the US FDA for treatment of HMB. Efficacy of tranexamic acid in the general gynecologic population as well as in women with bleeding disorders is discussed in this review. Safety and adverse effect profile is also addressed for both these populations.

Tranexamic acid: a new option for heavy menstrual bleeding

Heavy menstrual bleeding, or menorrhagia, af ects approximately one-third of women. Treatments have included nonsteroidal anti-inflammatories and oral contraceptives, although neither is approved by the Food and Drug Administration (FDA) specifically for this use. Lysteda® (tranexamic acid) has recently been approved as a treatment for heavy menstrual bleeding. This article gives a background on menorrhagia and describes treatment with tranexamic acid, including its implications for nurses.

Pharmacological therapy for abnormal uterine bleeding

Pharmacological therapies for the treatment of abnormal uterine bleeding are effective and generally well tolerated. This review presents an evidence-based approach to medical therapy. Selection depends on the etiology and amount of bleeding, need for contraception or preservation of fertility, perimenopause status, and medication efficacy and adverse effects.Available nonhormonal agents include nonsteroidal anti-inflammatory agents, which reduce bleeding by 25% to 35% and improve dysmenorrhea through reduced prostaglandin levels; tranexamic acid, which inhibits plasminogen activator with a 40% to 60% reduction in menstrual blood loss; and intranasal desmopressin, which is an antifibrinolytic for women with an underlying bleeding disorder (eg, von Willebrand disease).Hormonal regimens cause the inhibition of endometrial growth. Cyclic progestogen therapy for 21 days results in a significant reduction in menstrual blood loss. Limited data suggest that oral contraceptives reduce menstrual blood loss by 40% to 50% with decreased breast tenderness and dysmenorrhea and a reduction in risk of uterine and ovarian cancer. The progestin-releasing intrauterine devices are effective up to 97% by 6 months and provide relief of dysmenorrhea and contraception. Long-acting progestogen injections produce amenorrhea and provide contraception but are associated with irregular spotting and reversible bone loss. Danazol leads to endometrial atrophy with a reduced menstrual loss; androgenic adverse effects may be lessened with lower doses or vaginal use. Gonadotrophin agonists lead to ovarian suppression and are used to shrink fibroids or the endometrium preoperatively but are limited by hypoestrogenic adverse events. Emergency use of parenteral conjugated estrogens has a 70% chance of stopping abnormal bleeding but an increased risk of thrombosis.

A dose-response study of a novel, oral tranexamic formulation for heavy menstrual bleeding

OBJECTIVE

We sought to assess the efficacy and safety of 2 dosing regimens of a novel, oral tranexamic acid formulation (Lysteda; Ferring Pharmaceuticals Inc, Parsippany, NJ) in women with cyclic heavy menstrual bleeding.

STUDY DESIGN

This was a multicenter, double-blind, placebo-controlled, randomized, parallel-group trial for 3 menstrual cycles (n = 304). Women with mean menstrual blood loss (MBL) of ≥ 80 mL/cycle were randomized to receive either 1.95 g/d or 3.9 g/d of tranexamic acid or placebo for up to 5 days of menstrual bleeding. Primary efficacy endpoints were mean MBL reduction from baseline, mean MBL reductions that were considered "meaningful" by subjects, and mean MBL reductions from baseline > 50 mL/cycle. Adverse events (AEs) were also assessed.

RESULTS

Only the 3.9 g/d group met all 3 primary efficacy endpoints. AEs did not significantly differ among the 3 groups. There were no serious study-related AEs.

CONCLUSION

The 3.9-g/d dose met all 3 primary efficacy endpoints, whereas the 1.95 g/d dose met 2 primary efficacy endpoints. Both doses were well tolerated.

Estrogen and thrombosis: controversies and common sense

Soon after the introduction of hormonal oral contraceptive agents reports of thrombotic complications appeared. In the past several decades, large epidemiological studies helped defined these risks for both arterial and venous complications. Clinicians can assess a patient's risk of thrombosis by both composition of the agent and patients' personal risk factors. For women with bleeding disorders these prothrombotic changes can help decrease bleeding complications. There is now also abundant data on future management of patients with estrogen related thrombosis.

Tranexamic Acid: A Novel Oral Formulation for the Treatment of Heavy Menstrual Bleeding

Tranexamic acid, a synthetic lysine derivative, is an antifibrinolytic drug that prevents the breakdown of fibrin by competitively blocking binding sites of plasminogen. Tranexamic acid is often considered a first-line treatment for the management of heavy menstrual bleeding (HMB). A new oral formulation of tranexamic acid provides a nonhormonal HMB therapy that is safe, effective and well tolerated; is administered only during menstruation; addresses the excessive fibrinolysis implicated in many cases of HMB; and improves women's health-related quality of life by reducing limitations on physical, social and leisure activities. This article provides a summary of the clinical development, therapeutic efficacy and tolerability profile of this novel formulation of tranexamic acid for the treatment of HMB.

von Willebrand disease in the pediatric and adolescent population

Recent studies indicate that bleeding disorders, particularly von Willebrand disease (VWD) is more prevalent than previously thought in adolescents with menorrhagia. Menorrhagia management in undiagnosed disorders of hemostasis may be associated with unwanted risks and complications. The prevalence of symptomatic VWD in the pediatric primary care setting appears to be 0.11% (95% CI, 0.04-0.25%). Studies evaluating the prevalence of VWD in adolescents with menorrhagia have included over 500 patients with a prevalence range from 3 to 36% depending on the clinical setting studied, with the highest prevalence seen in adolescents referred to an outpatient Hemophilia Center, while the lowest prevalence is seen in the acute hospital setting. Recently, the diagnosis of VWD has been facilitated by the use of pediatric bleeding questionnaires that have proved useful in quantifying the severity of bleeding symptoms. Treatment of VWD is often complex because a combination of therapies is often required. Potential treatment options include estrogen-progesterone preparations, desmopressin, antifibrinolytic agents and von Willebrand factor concentrates. More research is needed to evaluate the effectiveness of the various treatment modalities in the adolescent population.

Tranexamic acid treatment for heavy menstrual bleeding: a randomized controlled trial

OBJECTIVE

To assess the efficacy and safety of an oral formulation of tranexamic acid for the treatment of heavy menstrual bleeding.

METHODS

Adult women with heavy menstrual bleeding (mean menstrual blood loss 80 mL or more per cycle) were enrolled in a double-blind, placebo-controlled study. After two pretreatment menstrual cycles, women were randomized to receive tranexamic acid 3.9 g/d or placebo for up to 5 days per menstrual cycle through six cycles. To meet the prespecified three-component primary efficacy end point, mean reduction in menstrual blood loss from baseline with tranexamic acid treatment needed to be 1) significantly greater than placebo, 2) greater than 50 mL, and 3) greater than a predetermined meaningful threshold (36 mL or higher). Health-related quality of life was measured using a validated patient-reported outcome instrument.

RESULTS

Women who received tranexamic acid (n=115) met all three primary efficacy end points: first, a significantly greater reduction in menstrual blood loss of -69.6 mL (40.4%) compared with -12.6 mL (8.2%) in the 72 women who received placebo (P<.001); reduction of menstrual blood loss exceeding a prespecified 50 mL; and last, reduction of menstrual blood loss considered meaningful to women. Compared with women receiving placebo, women treated with tranexamic acid experienced significant improvements in limitations in social or leisure and physical activities, work inside and outside the home, and self-perceived menstrual blood loss (P<.01). The majority of adverse events were mild to moderate in severity, and the incidence of gastrointestinal adverse events was comparable with placebo.

CONCLUSION

In this study, a new oral tranexamic acid treatment was well tolerated and significantly improved both menstrual blood loss and health-related quality of life in women with heavy menstrual bleeding.

Levonorgestrel Intrauterine System: A First-Line Medical Treatment for Heavy Menstrual Bleeding

Chronic heavy menstrual bleeding is a common gynecologic condition that causes significant health problems and negatively impacts a woman's quality of life. Surgical treatments should be reserved for women who have pelvic pathology and for those who fail medical therapy. The recent US FDA approval of the levonorgestrel-releasing intrauterine system as an indicated treatment for heavy menstrual bleeding in women who want to use intrauterine devices for birth control highlights the potential that this top tier contraceptive method offers as a first-line therapy for treatment of this problem in women of any reproductive age, without sacrificing their future fertility.

A benefit-risk review of systemic haemostatic agents: part 1: in major surgery

Systemic haemostatic agents play an important role in the management of blood loss during major surgery where significant blood loss is likely and their use has increased in recent times as a consequence of demand for blood products outstripping supply and the risks associated with transfusions. Their main application is as prophylaxis to reduce bleeding in major surgery, including cardiac and orthopaedic surgery and orthotopic liver transplantation. Aprotinin has been the predominant agent used in this setting; of the other antifibrinolytic agents that have been studied, tranexamic acid is the most effective and epsilon-aminocaproic acid may also have a role. Eptacog alfa (recombinant factor VIIa) has also shown promise. Tranexamic acid, epsilon-aminocaproic acid and eptacog alfa are generally well tolerated; however, when considering the methods to reduce or prevent blood loss intra- and postoperatively, the benefits of these agents need to be weighed against the risk of adverse events. Recently, concerns have been raised about the safety of aprotinin after an association between increased renal dysfunction and mortality was shown in retrospective observational studies and an increase in all-cause mortality with aprotinin relative to tranexamic acid or epsilon-aminocaproic acid was seen after a pre-planned periodic analysis of the large BART (Blood conservation using Antifibrinolytics in a Randomized Trial) study. The latter finding resulted in the trial being halted, and aprotinin has subsequently been withdrawn from the market pending detailed analysis of efficacy and safety results from the study. Part 1 of this benefit-risk review examines the efficacy and adverse effect profiles of systemic haemostatic agents commonly used in surgery, and provides individual benefit-risk profiles that may assist clinicians in selecting appropriate pharmacological therapy in this setting.
