Provera (Medroxyprogesterone Acetate) - Summary

PROVERA SUMMARY

PROVERA Tablets contain medroxyprogesterone acetate, which is a derivative of progesterone. It is a white to off-white, odorless crystalline powder, stable in air, melting between 200 and 210°C. It is freely soluble in chloroform, soluble in acetone and in dioxane, sparingly soluble in alcohol and in methanol, slightly soluble in ether, and insoluble in water.

PROVERA Tablets are indicated for secondary amenorrhea and for abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as fibroids or uterine cancer. PROVERA Tablets are also indicated to reduce the incidence of endometrial hyperplasia in nonhysterectomized postmenopausal women receiving 0.625 mg conjugated estrogen.

Elagolix, an oral GnRH antagonist, versus subcutaneous depot medroxyprogesterone acetate for the treatment of endometriosis: effects on bone mineral density. [2014]
This randomized double-blind study, with 24-week treatment and 24-week posttreatment periods, evaluated the effects of elagolix (150 mg every day, 75 mg twice a day) versus subcutaneous depot medroxyprogesterone acetate (DMPA-SC) on bone mineral density (BMD), in women with endometriosis-associated pain (n = 252)...

A four week randomised control trial of adjunctive medroxyprogesterone and tamoxifen in women with mania. [2014]
Emerging research has suggested that hormone treatments such as selective oestrogen receptor modulators (SERMs) or progestins may be useful in the treatment of mania. The current pilot study compared the use of the SERM tamoxifen and the progestin medroxyprogesterone acetate (MPA), as an adjunct to mood stabiliser medications, for the treatment of mania symptoms in 51 women in a 28-day double blind, placebo controlled study...

Differential effects of estrogen and micronized progesterone or medroxyprogesterone acetate on cognition in postmenopausal women. [2011.08]
OBJECTIVE: To investigate possible differential effects of the coadministration of conjugated equine estrogen (CEE) and a placebo (CEE + PL), CEE and medroxyprogesterone acetate (CEE + MPA), or CEE and micronized P (CEE + MP) on aspects of cognitive functioning in naturally postmenopausal women...

Effects of percutaneous estradiol-oral progesterone versus oral conjugated equine estrogens-medroxyprogesterone acetate on breast cell proliferation and bcl-2 protein in healthy women. [2011.03.01]
In a prospective, randomized clinical study 77 women were assigned randomly to receive sequential hormone therapy with either conventional oral conjugated equine estrogens (0.625 mg) with the addition on 14 of the 28 days of oral medroxyprogesterone acetate (5 mg) or natural E(2) gel (1.5 mg) with oral micronized P (200 mg) on 14 of the 28 days of each cycle.

Clinical Trials Related to Provera (Medroxyprogesterone)

Pilot Study of Femring Estrogen Supplementation During Depo-Provera Initiation [Completed]
Many women choose Depo-Provera for birth control because it is easy to use and very effective. However, a significant number of Depo-Provera users experience irregular bleeding during the first 90 days. Many users discontinue after their first injection due to irregular bleeding. This study will evaluate the effect of using an estrogen vaginal ring during the first 90 days of Depo-Provera use to see if it is acceptable to women and whether it decreases irregular bleeding during the first 90 days of use and increases continuation to a second injection.

Depo Provera Self-Administration Study: Putting a Patient-Centered Practice to the Test at Planned Parenthood [Not yet recruiting]
This randomized clinical trial will study subcutaneous depot medroxyprogesterone acetate (DMPA sc) self-administration at two Planned Parenthood affiliates serving diverse patient populations. Prior studies demonstrate that DMPA self-injection is safe, effective, feasible, and acceptable for women and adolescents. A total of 400 female patients (ages 15-44) requesting DMPA will be randomized to self-administration of DMPA sc or clinic administration (usual care). Subjects will be followed for one year. The primary study outcome is DMPA continuation at one year by self-report in both study arms. Secondary outcomes include patient-reported satisfaction with treatment; satisfaction with home use; and costs associated with contraceptive care. The investigators hypothesize higher continuation rates among self-injection users compared to patients who receive standard care. Secondary exploratory hypotheses include higher patient satisfaction and lower costs associated with contraceptive care among self-injection users.

Pharmacokinetic Interactions Between DMPA and LPV/Rit Among HIV-Infected Women [Completed]
This study is being done to look at the level of Depo-Provera, an injectable birth control, in the blood to see whether it is affected by the anti-HIV drug Kaletra (lopinavir/ritonavir [LPV/r]). It is not known whether taking Depo-Provera together with Kaletra changes the amount of Kaletra in blood. Therefore, this study will also look at the levels of HIV and Kaletra before and after receiving a shot of Depo-Provera. This study will take a look at the safety of Depo-Provera and Kaletra when they are used together. In addition to what is stated above, this study will also explore any effect of Depo-Provera on the immune system.

Timing of Postpartum Depot Medroxyprogesterone Acetate Administration on Breastfeeding, Contraceptive Continuation, and Depression [Recruiting]
In the United States, depot medroxyprogesterone acetate (DMPA) is given to women after delivery and before hospital discharge with the belief that women who delay starting DMPA may be more likely to become pregnant when they are not yet ready to be pregnant and that giving DMPA before discharge has little to no negative effect on breastfeeding. Administering DMPA to breastfeeding women has not been widely questioned because the limited existing studies do not show any adverse impact of DMPA on breastfeeding. However, these studies used inappropriate control groups and did not control for prior lactation experience. The investigators plan to enroll 184 women who are planning to breastfeed and use DMPA after delivery to find out whether the timing of postpartum administration of DMPA (prior to hospital discharge or 4-6 weeks after delivery) affects the duration or exclusivity of breastfeeding among women who plan to breastfeed their infants. The investigators will also look at rates of use of highly effective contraception (defined as DMPA, intrauterine device, implant, sterilization, or lactational amenorrhea) and postpartum depression.

Medroxyprogesterone +/- Cyclophosphamide & Methotrexate in Hormone Receptor-Negative Recurrent/Metastatic Breast Cancer [Completed]
The purpose of this study is to evaluate the impact of MPA alone and in combination with low dose oral chemotherapy in patients with ER- and PR- advanced breast cancer.

Dosage & duration:		50mg taken 2 times dailey for the period of 3 monts
Other conditions:		none

		Reported Results
Benefits:		resume ovulation and maintain hormonal balance
Side effects:		Horrible mood swings, crying episodes, confusion.
Comments:		In order to correct Polycystic ovarian syndrom and to get pregnant I was given Progestin and clomid to resume ovulation. I would NEVER* take either of these synthetics again! I was a basketcase with mood swings, crying, depression etc.. and once I discontinued use I was able to return to a normal mental state. I used this for over 3 months while my poor family suffered, never recieving the results I hoped for. I achieved results only when I went natural and used a natural progetserone cream from AIM made with wild yam and instead of horrific side effects I had pleasant ones...my acne cleared, my insomnia got better and my overall mood was improved, 3 months later I was pregnant! I will always try herbal before synthetics from now on.
