Leprostatic Agent
A leprostatic agent is a drug that interferes with proliferation of the bacterium that causes leprosy. The following agents are leprostatic agents: * acedapsone * clofazimine * dapsone * desoxyfructo-serotonin * diucifon * ethionamide * rifampicin * rifapentine * sulfameter * thalidomide Leprosy is a chronic infectious disease caused by ''Mycobacterium leprae''. Host defenses are crucial in determining the patient's response to the disease, the clinical presentation, and the bacillary load. These factors also influence the length of therapy and the risk of adverse reactions to medication. ''M. leprae'' cannot be grown on routine laboratory culture media, so drug sensitivity testing in vitro is not possible. Growth and drug susceptibility testing are done by injecting into animal models. One description of a clinical picture that results from tuberculoid leprosy is characterized by intact cell-mediated immunity, a positive lepromin skin reaction, granuloma formation, and a ...

Leprosy
Leprosy, also known as Hansen's disease (HD), is a Chronic condition, long-term infection by the bacteria ''Mycobacterium leprae'' or ''Mycobacterium lepromatosis''. Infection can lead to damage of the Peripheral nervous system, nerves, respiratory tract, skin, and eyes. This nerve damage may result in a lack of ability to feel pain, which can lead to the loss of parts of a person's Appendicular skeleton, extremities from repeated injuries or infection through unnoticed wounds. An infected person may also experience muscle weakness and poor eyesight. Leprosy symptoms may begin within one year, but for some people symptoms may take 20 years or more to occur. Leprosy is spread between people, although extensive contact is necessary. Leprosy has a low pathogenicity, and 95% of people who contract or who are exposed to ''M. leprae'' do not develop the disease. Spread is likely through a cough or contact with fluid from the nose of a person infected by leprosy. Genetic factors and i ...

Lepromatous Leprosy
Lepromatous leprosy is a form of leprosy characterized by pale macules in the skin. It results from the failure of Th1 cell activation which is necessary to eradicate the mycobacteria (Th1 response is required to activate macrophages that engulf and contain the disease). In lepromatous leprosy, TH2 response is turned on, and because of reciprocal inhibition (IL-4; IL-10), the cell-mediated response (TH1) is depressed. Lepromatous leprosy, in contrast to the tuberculoid form of leprosy, is characterized by the absence of epithelioid cells in the lesions. In this form of leprosy ''Mycobacterium leprae'' are found in lesion in large numbers. This is the most unfavorable clinical variant of leprosy. This debilitating form of leprosy begins to spread causing the eyebrows to disappear and spongy tumor like swellings appear on the face and body. The disease attacks the internal organs, bones, joints and marrow of the body resulting in physical degeneration. The result is deformity wit ...

Chemotherapy
Chemotherapy (often abbreviated chemo, sometimes CTX and CTx) is the type of cancer treatment that uses one or more anti-cancer drugs (list of chemotherapeutic agents, chemotherapeutic agents or alkylating agents) in a standard chemotherapy regimen, regimen. Chemotherapy may be given with a cure, curative intent (which almost always involves combinations of drugs), or it may aim only to prolong life or to Palliative care, reduce symptoms (Palliative care, palliative chemotherapy). Chemotherapy is one of the major categories of the medical discipline specifically devoted to pharmacotherapy for cancer, which is called ''oncology#Specialties, medical oncology''. The term ''chemotherapy'' now means the non-specific use of intracellular poisons to inhibit mitosis (cell division) or to induce DNA damage (naturally occurring), DNA damage (so that DNA repair can augment chemotherapy). This meaning excludes the more-selective agents that block extracellular signals (signal transduction) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarithromycin
Clarithromycin, sold under the brand name Biaxin among others, is an antibiotic used to treat various bacterial infections. This includes strep throat, pneumonia, skin infections, '' H. pylori'' infection, and Lyme disease, among others. Clarithromycin can be taken by mouth as a tablet or liquid or can be infused intravenously. Common side effects include nausea, vomiting, headaches, and diarrhea. Severe allergic reactions are rare. Liver problems have been reported. It may cause harm if taken during pregnancy. It is in the macrolide class and works by slowing down bacterial protein synthesis. Clarithromycin resistance is already a major challenge to healthcare systems and such resistance is spreading, leading to recommendations to test the susceptibility of pathogenic organisms to the antibiotic before commencing clarithromycin therapy. Clarithromycin was developed in 1980 and approved for medical use in 1990. It is on the World Health Organization's List of Essential Med ...

Minocycline
Minocycline, sold under the brand name Minocin among others, is a tetracycline antibiotic medication used to treat a number of bacterial infections such as some occurring in certain forms of pneumonia. It is generally (but not always) less preferred than the tetracycline doxycycline. Minocycline is also used for the treatment of acne and rheumatoid arthritis. It is taken by mouth or applied to the skin. Common side effects include nausea, diarrhea, dizziness, allergic reactions, and kidney problems. Serious side effects may include anaphylaxis, a lupus-like syndrome, and easy sunburning. Use in the later part of pregnancy may harm the baby and safety during breastfeeding is unclear. It works by decreasing a bacterium's ability to make protein thus stopping its growth. Minocycline was patented in 1961 and came into commercial use in 1971. It is available as a generic medication. In 2022, it was the 269th most commonly prescribed medication in the United States, with more th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ofloxacin
Ofloxacin is a quinolone antibiotic useful for the treatment of a number of bacterial infections. When taken Oral administration, by mouth or intravenous, injection into a vein, these include pneumonia, cellulitis, urinary tract infections, prostatitis, plague (disease), plague, and certain types of infectious diarrhea. Other uses, along with other medications, include treating multidrug resistant tuberculosis. An eye drop may be used for a superficial bacterial infection of the eye and an ear drop may be used for otitis media when a hole in the tympanic membrane, ear drum is present. When taken by mouth, common side effects include vomiting, diarrhea, headache, and rash. Other serious side effect include tendon rupture, numbness due to nerve damage, seizures, and psychosis. Use in pregnancy is typically not recommended. Ofloxacin is in the fluoroquinolone family of medications. It works by interfering with the bacterium's DNA.

Ethionamide
Ethionamide is an antibiotic used to treat tuberculosis. Specifically it is used, along with other antituberculosis medications, to treat active multidrug-resistant tuberculosis. It is no longer recommended for leprosy. It is taken by mouth. Ethionamide has a high rate of side effects. Common side effects include nausea, diarrhea, abdominal pain, and loss of appetite. Serious side effects may include liver inflammation and depression. It should not be used in people with significant liver problems. Use in pregnancy is not recommended as safety is unclear. Ethionamide is in the thioamides family of medications. It is believed to work by interfering with the use of mycolic acid. Ethionamide was discovered in 1956 and approved for medical use in the United States in 1965. It is on the World Health Organization's List of Essential Medicines. Medical uses Ethionamide is used in combination with other antituberculosis agents as part of a second-line regimen for active tuberculo ...

Rifampicin
Rifampicin, also known as rifampin, is an ansamycin antibiotic used to treat several types of bacterial infections, including tuberculosis (TB), ''Mycobacterium avium'' complex, leprosy, and Legionnaires' disease. It is almost always used together with other antibiotics with two notable exceptions: when given as a "preferred treatment that is strongly recommended" for latent TB infection; and when used as post-exposure prophylaxis to prevent ''Haemophilus influenzae'' type b and meningococcal disease in people who have been exposed to those bacteria. Before treating a person for a long period of time, measurements of liver enzymes and blood counts are recommended. Rifampicin may be given either by mouth or intravenously. Common side effects include nausea, vomiting, diarrhea, and loss of appetite. It often turns urine, sweat, and tears a red or orange color. Liver problems or allergic reactions may occur. It is part of the recommended treatment of active tuberculosis during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clofazimine
Clofazimine, sold under the brand name Lamprene, is a medication used together with rifampicin and dapsone to treat leprosy. It is specifically used for multibacillary (MB) leprosy and erythema nodosum leprosum, and its discovery greatly improved the overall efficiency of the treatment. Evidence is insufficient to support its use in other conditions, though a retrospective study found it 95% effective in the treatment of ''Mycobacterium avium'' complex (MAC) when administered together with a macrolide and ethambutol, as well as the drugs amikacin and clarithromycin. However, in the United States, clofazimine is currently considered an orphan drug, is unavailable in pharmacies, and its use in the treatment of MAC is overseen by the Food and Drug Administration. It is taken orally. Common side effects include abdominal pain, diarrhea, itchiness, dry skin, and change in skin color. It can also cause swelling of the lining of the gastrointestinal tract, increased blood sugar, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
