Randomized Trial of Mefenamic Acid Versus Tranexamic Acid in Management of Abnormal Uterine Bleeding

Menorrhagia, if repeated, causes a decrease in iron reserve and anemia and subsequently, anemia causes psychological and cardiac complications and dysfunction in other organs. So, paying attention to menorrhagia and its treatment can lead to lower morbidity in reproductive aged women. It is worth noticing that most of the iron deficient anemia morbidities are the result of more than 60 ml bleeding per cycle.

The evaluation of the actual bleeding volume is not an easy task because women's evaluation of their own bleeding volume is not reliable. 25% of the women who consider their bleeding level as high had menstrual bleeding less than 35 ml. The estimation of blood loss volume was done based on the number of pads or tampons soaking per day or per cycle. The patient's estimations of the bleeding volumes are not accurate and reliable because they are not well aware of the normal range of bleeding and their evaluations are inexact.

Ideally, a noninvasive investigation is preferred to an invasive one and also an economical investigation preferred to an expensive one; this applies equally to affluent countries and third world, that is why ultrasonography by any modality if available is considered to be a noninvasive procedure to investigate uterine lesions rather than hysteroscopy as a preliminary step .

Various imaging techniques are used to enable the precise localization and characterization of uterine pathology. Currently, the main diagnostic tools for AUB include ultrasonography and diagnostic hysteroscopy.

Menorrhagia is defined as complaint of heavy menstrual bleeding over several consecutive cycles. The upper limit of monthly bleeding is 80 ml per cycle, which is 2 standard deviations from the mean (mean menstrual bleeding per cycle is 36 - 52ml).
