Progesterone injection, a progestin, is a sterile solution of progesterone in a suitable vegetable oil available for intramuscular use. Progesterone occurs as a white or creamy white, crystalline powder. It is odorless and is stable in air. Practically insoluble in water, it is soluble in alcohol, acetone, and dioxane and sparingly soluble in vegetable oils.
This drug is indicated in amenorrhea and abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as submucous fibroids or uterine cancer.
Published Studies Related to Progesterone
Uterine NK cells regulate endometrial bleeding in women and are suppressed by the
progesterone receptor modulator asoprisnil. 
Uterine NK cells (uNK) play a role in the regulation of placentation, but their
functions in nonpregnant endometrium are not understood. We have previously
reported suppression of endometrial bleeding and alteration of spiral artery
morphology in women exposed to asoprisnil, a progesterone receptor modulator...

Progestogen levels, progesterone receptor gene polymorphisms, and mammographic density changes: results from the Postmenopausal Estrogen/Progestin Interventions Mammographic Density Study. [2011.11.18]
OBJECTIVE:: Estrogen plus progestin therapy (EPT) in postmenopausal women increases breast cancer risk and mammographic density to a higher extent than does estrogen therapy alone. Data from the randomized placebo-controlled Postmenopausal Estrogen/Progestin Interventions trial showed that EPT-induced increases in serum estrone and estrone sulfate levels were positively correlated with increases in mammographic density. Here, after adjusting for serum estrone and estrone sulfate levels, we investigated the roles of posttreatment serum progestogen increase and of progesterone receptor gene (PGR) genetic variations on changes in mammographic density... CONCLUSIONS:: Our results suggest that higher serum progestogen levels resulting from EPT treatment lead to greater increases in mammographic density.
[Impacts on the duration of vaginal bleeding and the levels of serum estradiol (E2) and progesterone (P) for patients of midtrimester induction of labor treated with moxibustion at Guanyuan (CV 4) and Shenque (CV 8)]. [2011.09]
OBJECTIVE: To verify the efficacy of moxibustion at Guanyuan (CV 4) and Shenque (CV 8) on the duration of vaginal bleeding for patients with midtrimester induction of labor and explore its mechanism... CONCLUSION: Moxibustion at Guanyuan (CV 4) and Shenque (CV 8) may shorten the duration of vaginal bleeding for patients with midtrimester induction of labor. Probably through the increase of serum E2 level and the decrease of P level, the uterine contraction is effectively enhanced and the excretion of placental villi and deciduas is promoted. As a result, endometrial repair occurs rapidly.
Clinical Trials Related to Progesterone
Evaluating the Roles of Estrogen and Progesterone in Heart Metabolism [Completed]
Estrogen and progesterone are two main female sex hormones. When a woman goes through
menopause, the body's production of estrogen and progesterone significantly decreases. Recent
studies have shown that the breakdown of fatty acids in cardiac muscle is important in
maintaining a healthy heart, and that estrogen may enhance this process. Also, cardiovascular
disease (CVD) occurs more frequently in postmenopausal women than in premenopausal women.
This study will determine in postmenopausal women whether estrogen increases the heart's
ability to use fats as energy and whether progesterone decreases this effect.
Multi-Center, Randomized, Open-Label, Parallel Group Study of a Vaginal Micronized Progesterone Tablet (Endometrin®) Compared to Crinone 8% Vaginal Gel in Female Patients Undergoing In-Vitro Fertilization (IVF) [Completed]
This multicenter, randomized, open-label study will be performed in approximately 990 healthy
females undergoing IVF. Each study center will follow their study center standard practice
for IVF unless otherwise noted in this protocol. The study centers will be provided with the
medications for down regulation, stimulation and ovulation induction. The subjects will be
randomized to study medication on the day of oocyte retrieval or the day following and will
continue treatment for up to 10 weeks. The subjects with a confirmed pregnancy will be
required to return to the clinic several times during the course of the 10 week treatment
period for serum pregnancy tests and transvaginal ultrasounds to monitor the pregnancy.
Artificial Endometrial Preparation for Frozen Thawed Embryo Transfer Applying Either Endometrin or Utrogestan [Suspended]
The transfer of frozen-thawed embryos can be performed in a natural ovulatory cycle or in a
hormonally manipulated cycle with a comparable pregnancy rate of 15%-20% per ET. When a
hormonally modulated ET cycle is scheduled,an artificial endometrial preparation is carried
out using estrogen stimulation followed by a concomitant progesterone treatment. Two
progestative drugs are currently used in conventional IVF treatment, Utrogetan and
Endometrin. Although Endometrin has been be efficiently used to support the luteal phase
after embryo transfer in IVF cycles, currently, there is no study that assess its efficacy
for clinical use in frozen-thawed ET cycles. The present study aims to compare the outcome of
frozen thawed ET cycles when either Endometrin or Utrogestan are used as the progestative
substitution in an artificially prepared endometrium.
Progesterone Reduces Wakefulness in Sleep EEG and Has no Effect on Cognition in Healthy Postmenopausal Women [Completed]
Sleep is impaired in postmenopausal women (difficulty falling asleep, frequent awakenings).
Progesterone prompted benzodiazepine-like effects on sleep EEG in young normal male
Aim of this study was to test if replacement therapy with progesterone improves sleep after
Design, Setting, and Participants: A double blind cross-over design study with 2 treatment
intervals of 21 days duration separated by a 2 weeks washout was performed. A oral dose of
300mg micronized progesterone was given each for 21 days. At the beginning and the end of the
two intervals a sleep EEG was recorded and cognitive performance was assessed in 10 healthy
postmenopausal women (age: 54-70 yrs).
Vaginal Progesterone as a Treatment for Women Active Preterm Labor [Recruiting]
The purpose of this study is to compare how well vaginal progesterone works delaying the
time to delivery in women with preterm labor compared to placebo. The study will also
compare the effect of vaginal progesterone on neonatal outcomes, rate of spontaneous preterm
delivery, cervical length and biomarkers of preterm delivery in women diagnosed with and
treated with medication to stop preterm labor.

Progesterone review by 47 year old female patient
|Overall rating:|| || |
|Effectiveness:|| || Highly Effective|
|Side effects:|| || No Side Effects|
|Condition / reason:|| || severe stomach pains, dizziness|
|Dosage & duration:|| || 50 mg taken once a day for the period of 3 months and still one it|
|Other conditions:|| || mood swings|
|Other drugs taken:|| || none|
|Benefits:|| || I have had stomach troubles my entire life. When I was pregnant they were unbearable. I could never take the pill because of nausea. I noticed that when I was 45 the nausea was associated with my cycle, becoming most intense just prior to my period. My gastroenterologist prescribed Nexium, which I took for a year, maximum dosage, daily and then tapered off. Then the other symptoms above emerged. When I started with the progesterone all these symptoms subsided significantly and I rarely ever have stomach problems now. |
|Side effects:|| || None at all that I am aware of.|
|Comments:|| || Prior to taking the oral treatment I used the cream, to avoid the digestive tract altogether. This was fine for about a year, but then the symptoms reappeared. My physician felt that something was interfering with the absorption of the hormones and so prescribed the oral pill and the symptoms have nearly disappeared and I have had no associated stomach problems. I am convinced that much of my stomach problems throughout my life were associated with a hormonal imbalance, but cannot prove this. I do know that this is the best my stomach has ever been in my entire life, for whatever reason.|
