Oxytocics
A uterotonic, also known as ecbolic, are pharmacological agents used to induce contraction or greater tonicity of the uterus. Uterotonics are used both to induce labor and to reduce postpartum hemorrhage. Labor induction in the third trimester of pregnancy may be required due to medical necessity, or may be desired for social reasons. Generally, labor induction is indicated when the risk of carrying the pregnancy outweighs the risk of delivering. These reason include, but are not limited to, pregnancies that are prolonged, prelabor rupture of the fetal membranes, and concerns about the health and safety of the mother and/or child. There are multiple techniques available to stimulate uterine contractions including mechanical, pharmacological, and alternative medicine methods to initiate contractions prior to spontaneous onset of labor. Postpartum bleeding, Postpartum hemorrhage, also known as PPH, is defined as a loss of 500 mL or greater of blood within 24 hours after giving birth. ...

Demoxytocin
Demoxytocin (INN) (brand names Sandopart, Odeax, Sandopral), also known as desaminooxytocin or deaminooxytocin, as well as 1-(3-mercaptopropanoic acid)oxytocin ( Mpa1">/nowiki>Mpa1/nowiki>OT), is an oxytocic peptide drug that is used to induce labor, promote lactation, and to prevent and treat puerperal (postpartum) mastitis (breast inflammation). Demoxytocin is a synthetic analogue of oxytocin and has similar activities, but is more potent and has a longer half-life in comparison. Unlike oxytocin, which is given via intravenous injection, demoxytocin is administered as a buccal tablet formulation. The drug was first synthesized in 1960 and was introduced into clinical practice in 1971 by Sandoz. It is marketed in several European countries, including Italy, Czech Republic, and Poland. It has the amino acid sequence Mpa-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2 (Mpa = β-mercaptopropionic acid), and is an analogue of oxytocin wherein the leading cysteine is replaced with β-mercapt ...

Uterine Atony
Uterine atony is the failure of the uterus to contract adequately following delivery. Contraction of the uterine muscles during labor compresses the blood vessels and slows flow, which helps prevent hemorrhage and facilitates coagulation. Therefore, a lack of uterine muscle contraction can lead to an acute hemorrhage, as the vasculature is not being sufficiently compressed. Text was copied from this source, which is available under Creative Commons Attribution 4.0 International License Uterine atony is the most common cause of postpartum hemorrhage, which is an emergency and potential cause of fatality. Across the globe, postpartum hemorrhage is among the top five causes of maternal death. Recognition of the warning signs of uterine atony in the setting of extensive postpartum bleeding should initiate interventions aimed at regaining stable uterine contraction. Risk factors There are many risk factors for uterine atony and several are due to the type of labor a mother experience ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prostaglandin
The prostaglandins (PG) are a group of physiologically active lipid compounds called eicosanoids having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are derived enzymatically from the fatty acid arachidonic acid. Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring. They are a subclass of eicosanoids and of the prostanoid class of fatty acid derivatives. The structural differences between prostaglandins account for their different biological activities. A given prostaglandin may have different and even opposite effects in different tissues in some cases. The ability of the same prostaglandin to stimulate a reaction in one tissue and inhibit the same reaction in another tissue is determined by the type of receptor to which the prostaglandin binds. They act as autocrine or paracrine factors with their target cells present in the immediate vicinity of the site of their ...

Dinoprostone
Prostaglandin E2 (PGE2), also known as dinoprostone, is a naturally occurring prostaglandin with oxytocic properties that is used as a medication. Dinoprostone is used in labor induction, bleeding after delivery, termination of pregnancy, and in newborn babies to keep the ductus arteriosus open. In babies it is used in those with congenital heart defects until surgery can be carried out. It is also used to manage gestational trophoblastic disease. It may be used within the vagina or by injection into a vein. PGE2 synthesis within the body begins with the activation of arachidonic acid (AA) by the enzyme phospholipase A2. Once activated, AA is oxygenated by cyclooxygenase (COX) enzymes to form prostaglandin endoperoxides. Specifically, prostaglandin G2 (PGG2) is modified by the peroxidase moiety of the COX enzyme to produce prostaglandin H2 (PGH2) which is then converted to PGE2. Common side effects of PGE2 include nausea, vomiting, diarrhea, fever, and excessive uterine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erectile Dysfunction
Erectile dysfunction (ED), also called impotence, is the type of sexual dysfunction in which the penis fails to become or stay erect during sexual activity. It is the most common sexual problem in men.Cunningham GR, Rosen RC. Overview of male sexual dysfunction. In: UpToDate, Martin KA (Ed), UpToDate, Waltham, MA, 2018. Through its connection to self-image and to problems in sexual relationships, erectile dysfunction can cause psychological harm. In about 80% of cases, physical causes can be identified. These include cardiovascular disease; diabetes mellitus; neurological problems, such as those following prostatectomy; hypogonadism; and drug side effects. About 10% of cases are psychological impotence, caused by thoughts or feelings; here, there is a strong response to placebo treatment. The term ''erectile dysfunction'' is not used for other disorders of erection, such as priapism. Treatment involves addressing the underlying causes, lifestyle modifications, and ...

Alprostadil
Prostaglandin E1 (PGE1), also known as alprostadil, is a naturally occurring prostaglandin which is used as a medication. In infants with congenital heart defects, it is delivered by slow injection into a vein to open the ductus arteriosus until surgery can be carried out. By injection into the penis or placement in the urethra, it is used to treat erectile dysfunction. Common side effects when given to babies include decreased breathing, fever, and low blood pressure. When used for erectile dysfunction side effects may include penile pain, bleeding at the site of injection, and prolonged erection (priapism). Prostaglandin E1 is in the vasodilator family of medications. It works by opening blood vessels and relaxing smooth muscle. Prostaglandin E1 was isolated in 1957 and approved for medical use in the United States in 1981. It is on the World Health Organization's List of Essential Medicines. Medical uses Patent ductus arteriosus Alprostadil is also used in maintain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarrhea
Diarrhea, also spelled diarrhoea, is the condition of having at least three loose, liquid, or watery bowel movements each day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. The most common cause is an infection of the intestines due to either a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea are: short duration watery diarrhea, short duration bloody diarrhea, and persistent diarrhea (lasting more than two wee ...

Vomiting
Vomiting (also known as emesis and throwing up) is the involuntary, forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose. Vomiting can be the result of ailments like food poisoning, gastroenteritis, pregnancy, motion sickness, or hangover; or it can be an after effect of diseases such as brain tumors, elevated intracranial pressure, or overexposure to ionizing radiation. The feeling that one is about to vomit is called nausea; it often precedes, but does not always lead to vomiting. Impairment due to alcohol or anesthesia can cause inhalation of vomit, leading to suffocation. In severe cases, where dehydration develops, intravenous fluid may be required. Antiemetics are sometimes necessary to suppress nausea and vomiting. Self-induced vomiting can be a component of an eating disorder such as bulimia, and is itself now classified as an eating disorder on its own, purging disorder. Complications Aspiration Vomiting is dan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypertension
Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a major cause of premature death worldwide. High blood pressure is classified as primary (essential) hypertension or secondary hypertension. About 90–95% of cases are primary, defined as high blood pressure due to nonspecific lifestyle and genetic factors. Lifestyle factors that increase the risk include excess salt in the diet, excess body weight, smoking, and alcohol use. The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause ...

Carboprost
Carboprost (INN, trade names for the tromethamine salts Hemabate, Tham) is a synthetic prostaglandin analogue of PGF2α (specifically, it is 15-methyl-PGF2α) with oxytocic properties. Carboprost's main use is in the obstetrical emergency of postpartum hemorrhage which reduces postpartum bleeding during these circumstances. Indication Used in postpartum hemorrhage caused by uterine atony not controlled by other methods. One study has shown that carboprost tromethamine is more effective than oxytocin in preventing postpartum hemorrhage in high-risk patients undergoing cesarean delivery. Carboprost is also used for the termination of pregnancy in the 2nd trimester.Hemabate ackage Insert New York, NY: Pharmacia and Upjohn Company; 2014. Unlabeled use: * Hemorrhagic Cystitis * PID Contraindication Contraindicated in severe cardiovascular, renal, and hepatic disease. It is also contraindicated in acute pelvic inflammatory disease.

Uterine Hyperstimulation
Uterine hyperstimulation or hypertonic uterine dysfunction is a potential complication of labor induction. This is displayed as Uterine tachysystole- the contraction frequency numbering more than five in a 10-minute time frame or as contractions exceeding more than two minutes in duration. Uterine hyperstimulation may result in fetal heart rate abnormalities, uterine rupture, or placental abruption. It is usually treated by administering terbutaline. Causes * Mistoprostol is a drug treatment for peptic ulcers that can also cause abortion or induce labor. The use of this drug (inserted vaginally) to induce labor can cause uterine hyperstimulation. Treatment Treatments of uterine hyperstimulation are primarily experimental. Those that have shown to alleviate the conditions are: * Prostoglandin E2 is administered before labor to minimize risk of uterine hyperstimulation and to minimize the effects on Fetal Heart Rate. * Administration of tocolytic treatment with β2-a ...
