Suppository
A suppository is a dosage form used to deliver medications by insertion into a body orifice where it dissolves or melts to exert local or systemic effects. There are three types of suppositories, each to insert into a different sections: rectal suppositories into the rectum, vaginal suppositories into the vagina, and urethral suppositories into the urethra of a male. Suppositories are ideal for infants, elderly individuals and post-operative patients, who are unable to swallow oral medications, and for individuals experiencing severe nausea and/or vomiting. Composition Several different ingredients can be used to form the base of a suppository: cocoa butter or a similar substitute, polyethylene glycol, hydrogels, and glycerinated gelatin. The type of material used depends on the type of suppository, the type of drug, and the conditions in which the suppository will be stored. Rectal suppositories In 1991, a study on suppository insertion in ''The Lancet'' found that the "torpe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pessary
A pessary is a prosthetic device inserted into the 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 individuals to purchase pessaries from a store 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 maintainin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laxatives
Laxatives, purgatives, or aperients are substances that loosen stools and increase bowel movements. They are used to treat and prevent constipation. Laxatives vary as to how they work and the side effects they may have. Certain stimulant, lubricant and saline laxatives are used to evacuate the colon for rectal and bowel examinations, and may be supplemented by enemas under certain circumstances. Sufficiently high doses of laxatives may cause diarrhea. Some laxatives combine more than one active ingredient. Laxatives may be administered orally or rectally. Types Bulk-forming agents Bulk-forming laxatives, also known as roughage, are substances, such as fiber in food and hydrophilic agents in over-the-counter drugs, that add bulk and water to stools so that they can pass more easily through the intestines (lower part of the digestive tract). Properties * Site of action: small and large intestines * Onset of action: 12–72 hours * Examples: dietary fiber, Metamucil, C ...

Rectal Administration
Rectal administration uses the rectum as a route of administration for medication and other fluids, which are absorbed by the rectum's blood vessels,The rectum has numerous blood vessels available to absorb drugs. and flow into the body's circulatory system, which distributes the drug to the body's organs and bodily systems.The organs and systems include, depending on if the drug is able to pass the blood–brain barrier (BBB) or not, the central nervous system (CNS), peripheral nervous system (PNS), cardiovascular system (CVS), et cetera. A drug that is administered rectally will in general (depending on the drug) have a faster onset, higher bioavailability, shorter peak, and shorter duration than oral administration. Another advantage of administering a drug rectally, is that it tends to produce less nausea compared to the oral route and prevents any amount of the drug from being lost due to emesis (vomiting). In addition, the rectal route bypasses around two-thirds of the ... [...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 addres ...

Drugs Acting On The Gastrointestinal System And Metabolism
A drug is any chemical substance that causes a change in an organism's physiology or psychology when consumed. Drugs are typically distinguished from food and substances that provide nutritional support. Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders. Pharmaceutical drugs are often classified into drug classes—groups of related drugs ...

Dosage Forms
Dosage forms (also called unit doses) are pharmaceutical drug products in the form in which they are marketed for use, with a specific mixture of active ingredients and inactive components (excipients), in a particular configuration (such as a capsule shell, for example), and apportioned into a particular dose. For example, two products may both be amoxicillin, but one is in 500 mg capsules and another is in 250 mg chewable tablets. The term unit dose can also sometimes encompass non-reusable ''packaging'' as well (especially when each drug product is individually packaged), although the FDA distinguishes that by ''unit-dose "packaging" or "dispensing"''. Depending on the context, ''multi(ple) unit dose'' can refer to distinct drug products ''packaged'' together, or to a ''single'' drug product containing multiple drugs and/or doses. The term dosage form can also sometimes refer ''only'' to the pharmaceutical formulation of a drug product's constituent drug substance(s) and any ble ...

Constipation
Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. The stool is often hard and dry. Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. Complications from constipation may include hemorrhoids, anal fissure or fecal impaction. The normal frequency of bowel movements in adults is between three per day and three per week. Babies often have three to four bowel movements per day while young children typically have two to three per day. Constipation has many causes. Common causes include slow movement of stool within the colon, irritable bowel syndrome, and pelvic floor disorders. Underlying associated diseases include hypothyroidism, diabetes, Parkinson's disease, celiac disease, non-celiac gluten sensitivity, colon cancer, diverticulitis, and inflammatory bowel disease. Medications associated with constipation include opioids, certain antacids, calcium channel blockers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anus
The anus (Latin, 'ring' or 'circle') is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, the residual semi-solid waste that remains after food digestion, which, depending on the type of animal, includes: matter which the animal cannot digest, such as bones; Summary at food material after the nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; and dead or excess gut bacteria and other endosymbionts. Amphibians, reptiles, and birds use the same orifice (known as the cloaca) for excreting liquid and solid wastes, for copulation and egg-laying. Monotreme mammals also have a cloaca, which is thought to be a feature inherited from the earliest amniotes via the therapsids. Marsupials have a single orifice for excreting both solids and liquids and, in females, a separate vagina for reproduction. Female placental mamm ...

Enema
An enema, also known as a clyster, is an injection of fluid into the lower bowel by way of the rectum.Cullingworth, ''A Manual of Nursing, Medical and Surgical'':155 The word enema can also refer to the liquid injected, as well as to a device for administering such an injection. In standard medicine, the most frequent uses of enemas are to relieve constipation and for bowel cleansing before a medical examination or procedure; also, they are employed as a lower gastrointestinal series (also called a barium enema), to treat traveler's diarrhea, as a vehicle for the administration of food, water or medicine, as a stimulant to the general system, as a local application and, more rarely, as a means of reducing temperature, as treatment for encopresis, and as a form of rehydration therapy (proctoclysis) in patients for whom intravenous therapy is not applicable. In other contexts, enemas are used by some alternative health therapies, used for enjoyment, chiefly as part of sexual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artesunate Suppositories
Artesunate suppositories are used for the treatment of malaria. Artesunate is an antimalarial water-soluble derivative of dihydroartemisinin. Artemisinins are sesquiterpene lactones isolated from ''Artemisia annua'', a Chinese traditional medicine. These suppositories are given rectally due to the risk of death from severe malaria, as described below. The risk of death from severe malaria is largely dependent on the time lag between the onset of symptoms and treatment. Rapid access and administration of effective treatment is therefore essential. For many patients, readily available oral drugs cannot be taken because of their symptoms (e.g., vomiting, convulsions, coma), and hospitals providing alternative, non-oral treatment are often inaccessible. The drug artesunate, given in rectal suppository form, provides a potential solution to this problem: it can be made available in remote areas and thus can be given at the onset of symptoms. Artesunate is one of a number of artemisinin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
