Generic names
Progesterone is the generic name of the drug in English and its INN, USAN, USP, BAN, DCIT, and JAN, while progestérone is its name in French and its DCF. It is also referred to as progesteronum in Latin, progesterona in Spanish and Portuguese, and progesteron in German. Brand names
Progesterone is marketed under a large number of brand names throughout the world. Examples of major brand names under which progesterone has been marketed include Crinone, Crinone 8%, Cyclogest, Endogest, Endometrin, Estima, Geslutin, Gesterol, Gestone, Luteina, Luteinol, Lutigest, Lutinus, Microgest, Progeffik, Progelan, Progendo, Progering, Progest, Progestaject, Progestan, Progesterone, Progestin, Progestogel, Prolutex, Proluton, Prometrium, Prontogest, Strone, Susten, Utrogest, and Utrogestan. Availability
Progesterone is widely available in countries throughout the world in a variety of formulations. Progesterone in the form of oral capsules; vaginal capsules, tablets/inserts, and gels; and intramuscular oil have widespread availability. The following formulations/routes of progesterone have selective or more limited availability:
A tablet of micronized progesterone which is marketed under the brand name Luteina is indicated for sublingual administration in addition to vaginal administration and is available in Poland and Ukraine. A progesterone suppository which is marketed under the brand name Cyclogest is indicated for rectal administration in addition to vaginal administration and is available in Cyprus, Hong Kong, India, Malaysia, Malta, Oman, Singapore, South Africa, Thailand, Tunisia, Turkey, the United Kingdom, and Vietnam. An aqueous solution of progesterone complexed with β-cyclodextrin for subcutaneous injection is marketed under the brand name Prolutex in the Czech Republic, Hungary, Italy, Poland, Portugal, Slovakia, Spain, and Switzerland.
Emulsions were said to be even more unreliable.Macrocrystalline aqueous suspensions of progesterone as well as microspheres of progesterone were investigated as potential progestogen-only injectable contraceptives and combined injectable contraceptives (with estradiol) by the late 1980s and early 1990s but were never marketed.Aqueous solutions of water-insoluble steroids were first developed via association with colloid solubility enhancers in the 1940s. An aqueous solution of progesterone for use by intravenous injection was marketed by Schering AG under the brand name Primolut Intravenous by 1962. One of its intended uses was the treatment of threatened abortion, in which rapid-acting effect was desirable. An aqueous solution of progesterone complexed with cyclodextrin to increase its water solubility was introduced for use by once-daily subcutaneous injection in Europe under the brand name Prolutex in the mid-2010s.In the 1950s, long-acting parenteral progestins such as hydroxyprogesterone caproate, medroxyprogesterone acetate, and norethisterone enanthate were developed and introduced for use by intramuscular injection. They lacked the need for frequent injections and the injection site reactions associated with progesterone by intramuscular injection and soon supplanted progesterone for parenteral therapy in most cases. Oral and sublingual
The first study of oral progesterone in humans was published in 1949. It found that oral progesterone produced significant progestational effects in the endometrium in women. Prior to this study, animal research had suggested that oral progesterone was inactive, and for this reason, oral progesterone had never been evaluated in humans. A variety of other early studies of oral progesterone in humans were also published in the 1950s and 1960s.
