Mifepristone
Mifepristone, and also known by its developmental code name RU-486, is a drug typically used in combination with misoprostol to bring about a medical abortion during pregnancy. This combination is 97% effective during the first 63 days (9 weeks) of pregnancy, yet effective in the second trimester as well. It is also used on its own to treat Cushing's syndrome or for use as a low-dose Emergency contraception, emergency contraceptive. The most common adverse effects include abdominal pain, feeling tired, and vaginal bleeding. Serious side effects may include heavy vaginal bleeding, bacterial infection, and, if pregnant, birth defects. When used, appropriate follow-up care needs to be available. Mifepristone is primarily an antiprogestogen. It works by blocking the effects of progesterone, making both the cervix and uterine vessels dilate and causing uterine contraction. Mifepristone also works, to a less extent, as an antiglucocorticoid and diminishes the effects of hypercortis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medication Abortion
A medical abortion, also known as medication abortion or non-surgical abortion, occurs when drugs (medication) are used to bring about an abortion. Medical abortions are an alternative to surgical (also called procedural or instrumentation) abortions such as vacuum aspiration or dilation and curettage. Medical abortions are more common than surgical abortions in most places around the world. Medical abortions are most commonly performed by administering a two-drug combination: mifepristone followed by misoprostol. This two-drug combination is more effective than other drug combinations. When mifepristone is not available, misoprostol alone may be used in some situations. Medical abortion is both safe and effective throughout a range of Gestational age, gestational ages, including the second and third trimester. It gets progressively riskier and less effective as the pregnancy advances, especially in third trimester. In the United States, the mortality rate for medical abortio ...

Pessary
A pessary is a prosthetic device inserted into the Human vagina, vagina for structural and pharmaceutical purposes. It is most commonly used to treat Stress incontinence, stress urinary incontinence to stop urinary leakage and to treat pelvic organ prolapse to maintain the location of organs in the pelvic region. It can also be used to administer medications locally in the vagina or as a method of contraception. Pessaries come in different shapes and sizes, so it is important that individuals be fitted for them by health care professionals to avoid any complications. However, there are a few instances and circumstances that allow pessaries to be purchased without a prescription or without seeking help from a health care professional. Some side effects may occur if pessaries are not sized properly or regularly maintained, but with the appropriate care, pessaries are generally safe and well tolerated. History Early use of pessaries dates back to the ancient Egyptians, as they d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analog (chemistry)
A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or substructures. A structural analog can be imagined to be formed, at least theoretically, from the other compound. Structural analogs are often isoelectronic. Despite a high chemical similarity, structural analogs are not necessarily functional analogs and can have very different physical, chemical, biochemical, or pharmacological properties. In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study or a database is screened for structural analogs of a lead compound. Chemical analogues of illegal drugs are developed and sold in order to circumvent la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prostaglandin E1
Prostaglandin E1 (PGE1) is a naturally occurring prostaglandin with various medical uses. Alprostadil and misoprostol are synthetic forms of prostaglandin E1 used as medications. Lubiprostone, a derivative of prostaglandin E1, is also used as a medication. Prostaglandin E1 is a vasodilator. It has various effects in the body that include opening blood vessels, relaxing smooth muscle, inhibiting clotting, and causing uterine contractions. In infants with certain congenital heart defects, alprostadil is delivered by slow injection into a vein to maintain a patent ductus arteriosus until surgery can be carried out. By injection into the penis or placement in the urethra, alprostadil is used to treat erectile dysfunction. Common side effects when given to babies include decreased breathing, fever, and low blood pressure. When injected into the penis for erectile dysfunction; side effects may include penile pain, bleeding at the site of injection, and prolonged erection (pr ...

Obstetrical Hemorrhage
Obstetrical bleeding is bleeding in pregnancy that occurs before, during, or after childbirth. Bleeding before childbirth is that which occurs after 24 weeks of pregnancy. Bleeding may be vaginal or less commonly into the abdominal cavity. Bleeding which occurs before 24 weeks is known as early pregnancy bleeding. Causes of bleeding before and during childbirth include cervicitis, placenta previa, placental abruption and uterine rupture. Causes of bleeding after childbirth include poor contraction of the uterus, retained products of conception, and bleeding disorders. About 8.7 million cases of severe maternal bleeding occurred in 2015 resulting in 83,000 deaths. Between 2003 and 2009, bleeding accounted for 27% of maternal deaths globally. Later pregnancy Antepartum bleeding (APH), also prepartum hemorrhage, is bleeding during pregnancy from the 24th week [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrexia
Fever or pyrexia in humans is a symptom of an anti-infection defense mechanism that appears with body temperature exceeding the normal range caused by an increase in the body's temperature set point in the hypothalamus. There is no single agreed-upon upper limit for normal temperature: sources use values ranging between in humans. The increase in set point triggers increased muscle contractions and causes a feeling of cold or chills. This results in greater heat production and efforts to conserve heat. When the set point temperature returns to normal, a person feels hot, becomes flushed, and may begin to sweat. Rarely a fever may trigger a febrile seizure, with this being more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from non-serious to life-threatening. This includes viral, bacterial, and parasitic infections—such as influenza, the common cold, meningitis, urinary tract infections, append ...

Hypotension
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the maximum and minimum blood pressures within the cardiac cycle, respectively. A systolic blood pressure of less than 90 millimeters of mercury (mmHg) or diastolic of less than 60 mmHg is generally considered to be hypotension. Different numbers apply to children. However, in practice, blood pressure is considered too low only if noticeable symptoms are present. Symptoms may include dizziness, lightheadedness, confusion, feeling tired, weakness, headache, blurred vision, nausea, neck or back pain, an irregular heartbeat or feeling that the heart is skipping beats or fluttering, sweating, an ...

Myocardial Infarction
A myocardial infarction (MI), commonly known as a heart attack, occurs when Ischemia, blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. The most common symptom is retrosternal Angina, chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. The pain may occasionally feel like heartburn. This is the dangerous type of acute coronary syndrome. Other symptoms may include shortness of breath, nausea, presyncope, feeling faint, a diaphoresis, cold sweat, Fatigue, feeling tired, and decreased level of consciousness. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an Cardiac arrhythmia, irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur d ...

Abortifacients
An abortifacient ("that which will cause a miscarriage" from Latin: ''abortus'' "miscarriage" and '' faciens'' "making") is a substance that induces abortion. This is a nonspecific term which may refer to any number of substances or medications, ranging from herbs to prescription medications. Common abortifacients used in performing medical abortions include mifepristone, which is typically used in conjunction with misoprostol in a two-step approach. Synthetic oxytocin, which is routinely used safely during term labor, is also commonly used to induce abortion in the second or third trimester. For thousands of years, writers in many parts of the world have described and recommended herbal abortifacients to women who seek to terminate a pregnancy, although their use may carry risks to the health of the woman. Medications Because "abortifacient" is a broad term used to describe a substance's effects on pregnancy, there is a wide range of drugs that can be described as abortifa ...

Prostaglandins
Prostaglandins (PG) are a group of physiologically active lipid compounds called eicosanoids that have 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 secretion ...
