YKey: TYZROVQLWOKYKF- ZDUSSCGKSA- N Y NY (what is this?)  (verify)Linezolid is an antibiotic used for the treatment of infections caused by Gram- positive bacteria that are resistant to other antibiotics.[2][1] Linezolid is active against most Gram- positive bacteria that cause disease, including streptococci, vancomycin- resistant enterococci (VRE), and methicillin- resistant Staphylococcus aureus (MRSA).[3] The main uses are infections of the skin and pneumonia although it may be used for a variety of other infections including drug resistant tuberculosis.[1][4] It is used either by injection into a vein or by mouth.[1] Linezolid is a member of the oxazolidinone class of medications.[1]When given for short periods, linezolid is a relatively safe antibiotic.[2] It can be used in people of all ages and in people with liver disease or poor kidney function.[1] Common side effects with short- term use include headache, diarrhea, rash, and nausea.[1] Serious side effects may include serotonin syndrome, bone marrow suppression, and high blood lactate levels, particularly when used for more than two weeks.[1][5] If used for longer periods still, it may cause sometimes irreversible nerve damage including optic nerve damage.[5]As a protein synthesis inhibitor, it affects the ability of bacteria to produce protein.[6] This either stops growth or results in bacterial death.[1] Although many antibiotics work this way, the exact mechanism of action of linezolid appears to be unique in that it blocks the start of protein production, rather than one of the later steps.[6] As of 2. Linezolid was discovered in the mid 1. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[1. Linezolid is available as a generic medication.[1] The wholesale cost in the developing world is about US$ 2. USD per day[1. 1] while that in the United States as of 2.

US$1. 3. 7. 9 per day.[1. It appears to be more cost- effective than alternatives such as vancomycin, mostly because of the ability to switch from intravenous use to administration by mouth sooner.[1. Medical uses[edit]The main use of linezolid is the treatment of severe infections caused by anaerobic Gram- positive bacteria that are resistant to other antibiotics; it should not be used against bacteria that are sensitive to drugs with a narrower spectrum of activity, such as penicillins and cephalosporins.

In both the popular press and the scientific literature, linezolid has been called a "reserve antibiotic"—one that should be used sparingly so that it will remain effective as a drug of last resort against potentially intractable infections.[1. In the United States, the indications for linezolid use approved by the U.

S. Food and Drug Administration (FDA) are the treatment of vancomycin- resistant Enterococcusfaeciuminfections, with or without bacterial invasion of the bloodstream; nosocomial pneumonia (hospital- acquired) and community- acquired pneumonia caused by S. S. pneumoniae; complicated skin and skin structure infections (c. SSSI) caused by susceptible bacteria, including diabetic foot infection, unless complicated by osteomyelitis (infection of the bone and bone marrow); and uncomplicated skin and soft tissue infections caused by S. S. aureus.[3] The manufacturer advises against the use of linezolid for community- acquired pneumonia or uncomplicated skin and soft tissue infections caused by MRSA.[3] In the United Kingdom, pneumonia and c. SSSIs are the only indications noted in the product labeling.[1.

Linezolid appears to be as safe and effective for use in children and newborns as it is in adults.[1. Skin and soft tissue infections[edit]A large meta- analysis of randomized controlled trials found linezolid to be more effective than glycopeptide antibiotics (such as vancomycin and teicoplanin) and beta- lactam antibiotics in the treatment of skin and soft tissue infections (SSTIs) caused by Gram- positive bacteria,[1. Gram- positive infections.[2.

Indications and Usage for Malarone. Prevention of Malaria. Malarone® is indicated for the prophylaxis of Plasmodium falciparum malaria, including in areas where chloroquine resistance has been reported. Treatment of Malaria.

Malarone is indicated for the treatment of acute, uncomplicated P. falciparum malaria. Malarone has been shown to be effective in regions where the drugs chloroquine, halofantrine, mefloquine, and amodiaquine may have unacceptable failure rates, presumably due to drug resistance.

Malarone Dosage and Administration. The daily dose should be taken at the same time each day with food or a milky drink. In the event of vomiting within 1 hour after dosing, a repeat dose should be taken. Malarone may be crushed and mixed with condensed milk just prior to administration to patients who may have difficulty swallowing tablets. Prevention of Malaria. Start prophylactic treatment with Malarone 1 or 2 days before entering a malaria‑endemic area and continue daily during the stay and for 7 days after return. Adults. One Malarone Tablet (adult strength = 2.

Pediatric Patients. The dosage for prevention of malaria in pediatric patients is based upon body weight (Table 1). Table 1. Dosage for Prevention of Malaria in Pediatric Patients. Weight(kg)Atovaquone/Proguanil HCl. Total Daily Dose. Dosage Regimen. 11- 2.

Malarone Tablets (adult strength) as a single daily dose for 3 consecutive days. Renal Impairment. Do not use Malarone for malaria prophylaxis in patients with severe renal impairment (creatinine clearance < 3.

L/min) [see Contraindications (4. Use with caution for the treatment of malaria in patients with severe renal impairment, only if the benefits of the 3- day treatment regimen outweigh the potential risks associated with increased drug exposure.

No dosage adjustments are needed in patients with mild (creatinine clearance 5. L/min) or moderate (creatinine clearance 3. L/min) renal impairment. See Clinical Pharmacology (1.

Stevens- Johnson syndrome, angioedema, vasculitis) to atovaquone or proguanil hydrochloride or any component of the formulation. Severe Renal Impairment. Malarone is contraindicated for prophylaxis of P. falciparum malaria in patients with severe renal impairment (creatinine clearance < 3. L/min) because of pancytopenia in patients with severe renal impairment treated with proguanil [see Use in Specific Populations (8. Clinical Pharmacology (1. Warnings and Precautions. Vomiting and Diarrhea.

Absorption of atovaquone may be reduced in patients with diarrhea or vomiting. If Malarone is used in patients who are vomiting, parasitemia should be closely monitored and the use of an antiemetic considered. See Dosage and Administration (2).] Vomiting occurred in up to 1. Malarone. In the controlled clinical trials, 1.

In patients with severe or persistent diarrhea or vomiting, alternative antimalarial therapy may be required. Relapse of Infection. In mixed P. falciparum and Plasmodium vivax infections, P. vivax parasite relapse occurred commonly when patients were treated with Malarone alone.

In the event of recrudescent P. falciparum infections after treatment with Malarone or failure of chemoprophylaxis with Malarone, patients should be treated with a different blood schizonticide. Hepatotoxicity. Elevated liver laboratory tests and cases of hepatitis and hepatic failure requiring liver transplantation have been reported with prophylactic use of Malarone. Severe or Complicated Malaria.
