- the present invention relates to a liquid vaginal spray dosage form that provide local as well as systemic effect, comprising therapeutically effective amount of natural/synthetic progesterone, useful for treatment of secondary amenorrhea, threatened or habitual abortions and infertility.
- Progesterone also known as P4 (pregn-4-ene-3,20-dione), is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestogens, and is the major naturally occurring human progestogen.
- Progesterone is pregn-4-ene-3,20-dione having structural formula as follows:
- Dioscorea mexicana belonging to yam family.
- Dioscorea mexicana produces large amounts of a steroid called diosgenin, which can be converted into progesterone in the laboratory.
- Progesterone exerts its primary action through the intracellular progesterone receptor although a distinct, membrane bound progesterone receptor has also been postulated. Progesterone and its analogues have many medical applications both to address acute situations and to address the long-term decline of natural progesterone levels. Progesterone is poorly absorbed by oral ingestion unless micronised and in oil, or with fatty foods; it does not dissolve in water.
- Progestogens were originally developed because they were capable of being absorbed into the blood when ingested in pill form, whereas progesterone itself was ot orally absorbed. Recently, however, it has been found that micronization of progesterone (making very tiny crystals of the progesterone) enhances absorption from the gastrointestinal tract. Thus micronized progesterone is now sometimes being used for menopausal hormone replacement therapy instead of progestogens. Birth control pills still have progestogens as the active progesterone-like component.
- vaginal route of progesterone administration provides many advantages such as easy administration, lack of local pain, avoids liver first-pass metabolism, rapid absorption and has no systemic side-effects. Consequently, the vagina has a large potential for absorption, and through the 'uterine first-pass effect' vaginal administration results in higher uterine progesterone concentrations.

Description
"LIQUID VAGINAL SPRAY OF PROGESTERONE"
TECHNICAL FIELD OF THE INVENTION:
The present invention relates to a liquid vaginal spray dosage form that provide local as well as systemic effect, comprising therapeutically effective amount of natural/synthetic progesterone, useful for treatment of secondary amenorrhea, threatened or habitual abortions and infertility.
BACKGROUND OF THE INVENTION;
Progesterone also known as P4 (pregn-4-ene-3,20-dione), is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestogens, and is the major naturally occurring human progestogen.
Chemically, Progesterone is pregn-4-ene-3,20-dione having structural formula as follows:
Progesterone is commonly manufactured from the plant called Dioscorea mexicana, belonging to yam family. Dioscorea mexicana produces large amounts of a steroid called diosgenin, which can be converted into progesterone in the laboratory.
Progesterone exerts its primary action through the intracellular progesterone receptor although a distinct, membrane bound progesterone receptor has also been postulated. Progesterone and its analogues have many medical applications both to address acute situations and to address the long-term decline of natural progesterone levels.
Progesterone is poorly absorbed by oral ingestion unless micronised and in oil, or with fatty foods; it does not dissolve in water.
Progestogens were originally developed because they were capable of being absorbed into the blood when ingested in pill form, whereas progesterone itself was ot orally absorbed. Recently, however, it has been found that micronization of progesterone (making very tiny crystals of the progesterone) enhances absorption from the gastrointestinal tract. Thus micronized progesterone is now sometimes being used for menopausal hormone replacement therapy instead of progestogens. Birth control pills still have progestogens as the active progesterone-like component.
The vaginal route of progesterone administration provides many advantages such as easy administration, lack of local pain, avoids liver first-pass metabolism, rapid absorption and has no systemic side-effects. Consequently, the vagina has a large potential for absorption, and through the 'uterine first-pass effect' vaginal administration results in higher uterine progesterone concentrations.
In view of the above, vaginal administration of progesterone results in high concentration of the hormone at the uterine level (first uterine passage), which may be advantageous for certain indications such as HRT (Hormone Replacement Therapy).
WO2008154240 discloses a solid, compressed pharmaceutical composition, containing only progesterone or progesterone combined with estradiol, to be administered vaginally in the form of tablet.
WO2004080413 discloses a formulation for the transdermal or transmucosal administration of an active agent comprising testosterone along with estrogen or progestin for the treatment of hypogonadism, female sexual desire disorder, female menopausal disorder, and adrenal insufficiency.
US2005181045 discloses the preparation of pharmaceutical composition containing micronized progesterone in the form of tablet, for vaginal delivery.
An article titled "Efficacy of Oral Micronized Progesterone when Applied via Vaginal Route" by Roungsin Choavaratana and Darapa Manoch discloses the comparative study of the efficacy of oral micronized progesterone when applied by the vaginal route. The authors conclude that the serum progesterone level achieved when micronized progesterone capsule was administered as a vaginal suppository is significantly higher than the level achieved by oral administration.
US607753 1 discloses a medicament based on estradiol and progesterone intended for the treatment of menopausal pathology.
In view of the above state of art, the present inventors have come up with a composition in a liquid vaginal spray dosage form comprising natural/synthetic progesterone to provide relatively better effect and quick absorption than other dosage forms like vaginal capsules or tablets. Further, the novel mode of delivery is useful for treatment of threatened or habitual abortions and infertility and provides better patient compliance as compare to painful intramuscular injections, as it is in solution form.
