Amphotericin B (Fungizone)
Amphotericin B
(am-foe- TER-ih-sin)
Pregnancy Category: B Fungizone Fungizone Intravenous (Rx)
Amphotericin B Lipid Complex (Amphotericin B Cholesteryl Sulfate Complex)
Amphotericin B Lipid Complex (Abelcet)
Amphotericin B Lipid Complex
(am-foe- TER-ih-sin)
Pregnancy Category: B Abelcet AmBisome Amphotec (Rx)

Classification: Antibiotic, antifungal

See Also: See also Anti-Infectives.

Action/Kinetics: This antibiotic is produced by Streptomyces nodosus; it is fungistatic or fungicidal depending on the concentration of the drug in body fluids and the susceptibility of the fungus. Amphotericin B binds to specific chemical structures--sterols--of the fungal cellular membrane, increasing cellular permeability and promoting loss of potassium and other substances. Liposomal encapsulation or incorporation in a lipid complex can significantly affect the functional properties of the drug compared with those of the unencapsulated or non-lipid-associated drug. The liposomal amphotericin B product causes less nephrotoxicity. Amphotericin B is used either IV or topically. It is highly bound to serum protein (90%) Peak plasma levels: 0.5-2 mcg/mL. t 1/2, initial: 24 hr; second phase: 15 days. Slowly excreted by kidneys.The kinetics of the drug differ in adults and children and are also dependent on the product used.

Uses: The drug is toxic and should be used only for clients under close medical supervision with progressive or potentially fatal fungal infections. Systemic Amphotericin B deoxycholate: Disseminated North American blastomycosis, cryptococcosis, and other systemic fungal infections, including coccidioidomycosis, histoplasmosis, aspergillosis, sporotrichosis, disseminated candidiasis, and monilial overgrowth resulting from oral antibiotic therapy. Zygomycosis, including mucormycosis due to Mucor, Rhizopus and Absidia species. Infections due to susceptible species of Conidiobolus and Basidiobolus. Secondary therapy to treat American mucocutaneous leishmaniasis.
Lipid-based Amphotericin B: The lipid complex (Abelcet) is used in those refractory to amphotericin B deoxycholate or where renal impairment or unacceptable toxicity precludes use of the deoxycholate product for treatment of invasive fungal infections. The cholesteryl product (Amphotec) is used to treat invasive aspergillosis infections. The liposomal product (AmBisome) is used to treat infections caused by Aspergillus, Candida or Cryptococcus species, as well as for empirical treatment in febrile, neutropenic clients with presumed fungal infections.
Investigational: Prophylaxis of fungal infections in clients with bone marrow transplantation. Treatment of primary amoebic meningoencephalitis due to Naegleria fowleri. Subconjunctival or intravitreal injection in ocular aspergillosis. As a bladder irrigation for candidal cystitis. Chemoprophylaxis by low dose IV, intranasal, or nebulized administration in immunocompromised clients at risk of aspergillosis. Intrathecally in those with severe meningitis unresponsive to IV deoxycholate therapy. Intra-articularly or IM for coccidiodal arthritis.
Topical: Cutaneous and mucocutaneous infections of Candida (Monilia) infections, especially in children, adults, and AIDS clients with thrush.

Contraindications: Hypersensitivity to drug unless the condition is life-threatening and amenable only to amphotericin B therapy. Use to treat common forms of fungal diseases showing only positive skin or serologic tests. Use to treat noninvasive forms of fungal disease such as oral thrush, vaginal candidiasis, and esophageal candidiasis in clients with normal neutrophil counts. Lactation.

Special Concerns: The bone marrow depressant effects may result in increased incidence of microbial infection, delayed healing, and gingival bleeding. Although used in children, safety and efficacy have not been determined. Use with caution in clients receiving leukocyte transfusions.

Side Effects: After topical use. Irritation, pruritus, dry skin. Redness, itching, or burning especially in skin folds. After IV use. Most common are listed. General toxic reaction: Fever sometimes with shaking chills usually within 15 to 20 min after treatment, headache, anorexia, malaise, generalized pain (including muscle and joint pain). GI: N&V, dyspepsia, diarrhea, cramping, epigastric pain, abdominal pain, melena, stomatitis, anorexia. CNS: Confusion, headache, depression, abnormal thinking, insomnia. CV: Hypotension, hypertension, tachycardia, tachypnea, arrhythmias. Dermatologic: Rash, pruritus, maculopapular rash. GU: Hematuria, decreased renal function, renal tubular acidosis, nephrocalcinosis, azotemia, hypokalemia, hyposthenuria. Respiratory: Respiratory failure respiratory disorder, pneumonia, dyspnea, hypoxia, epistaxis, increased cough, lung disorder, hemoptysis, hyperventilation, apnea, pleural effusion, rhinitis. Hematologic: Normochromic, normocytic anemia; increased PT, anemia, coagulation disorder. Metabolic: Bilirubinemia, acidosis, hypovolemia. At site of injection: Venous pain at injection site with phlebitis and thrombophlebitis. Miscellaneous: Weight loss, multiple organ failiure infection, sweating, pain, chest pain, back pain, sepsis facial edema, mucous membrane disorder, asthenia, peripheral edema, eye hemorrhage, blood product transfusion reaction, chills. After intrathecal use: Blurred vision, changes in vision, difficulty in urination, numbness, tingling, pain, or weakness.

Laboratory Test Alterations: AST, ALT, GGT, LDH, alkaline phosphatase, serum creatinine, BUN, bilirubin, BSP retention values, PT. Hypomagnesemia, hyperkalemia, hypocalcemia, hypercalemia, acidosis, hypoglycemia, hyperglycemia, hypermyalesmia, hyperuricemia, hypophosphatemia.

Overdose Management: Symptoms: Cardiopulmonary arrest. Treatment: Discontinue therapy, monitor clinical status, and provide supportive therapy.

Drug Interactions: Aminoglycosides / Additive nephrotoxicity and/or ototoxicity Antineoplastic drugs / Risk for renal toxicity, bronchospasm, and hypotension Corticosteroids, Corticotropin / Potassium depletion caused by amphotericin B cardiac dysfunction Cyclosporine / Renal toxicity Digitalis glycosides / Potassium depletion caused by amphotericin B incidence of digitalis toxicity Flucytosine / Risk of flucytosine toxicity due to cellular uptake or renal excretion Nephrotoxic drugs / Risk of nephrotoxicity Skeletal muscle relaxants, surgical (e.g., succinylcholine, d-tubocurarine ) / Muscle relaxation due to amphotericin B-induced hypokalemia Tacrolimus / Serum creatinine levels Thiazides / Electrolyte depletion, especially potassium AZT / Risk of myelotoxicity and nephrotoxicity

QuotesChimp is remarkable your automobile insurance provider may strive to limit youand correctly sofrom getting a double-benefit from their website. Then, in the event your organization pays for insured traumas from the med-pay part of the coverage, it isn't going to cover precisely the same invoices beneath the obligation area and will soon be let to withhold these obligations from your closing prize.

This article is so true the efctfes of probiotics seems to be far reaching, there is still much to be discovered regarding their usefulness. I would like to point out that Saccharomyces Boulardii is a probiotic but it is a yeast and not a bacteria. It is noncomensal so it does not take up permanent residence in the body. It helps protect he body against yeasts that would colonize in the gut to cause problems.

Conformity with QuotesChimp legislation. The Majority Of states permit insurers to won't revive for almost any rationale. Some, but avoid non-renewal according to age, sex, competition, or vocation. That Is about it. Oh, some states need you to be informed the rationale you aren't being revived, but that's not typically rough to determine. It might be a solution or 2, a collision, or some task the business consideres raisees your threat. Way also many times, this means simply trying to get insurance rewards to which you're officially titled.

Can Ampho B cause bone spurs, along with kidney failure. Not to speak of Osteoprosis in later years of an adults life span?
