High single doses or repeated low doses have been reported to produce hypotonia, poor sucking, and hypothermia in the neonate, and irregularities in the fetal heart. The committee recommended that benzodiazepines be avoided in lactation.The committee recommended that withdrawal from benzodiazepines be gradual, as abrupt withdrawal from high doses of benzodiazepines may cause confusion, toxic psychosis, convulsions, or a condition resembling delirium tremens. Abrupt withdrawal from lower doses may cause depression, nervousness, rebound insomnia, irritability, sweating, and diarrhea. Treatment
Benzodiazepines are regarded as a highly addictive drug class. A psychological and physical dependence can develop in as short as a few weeks but may take years to develop in other individuals. Patients wanting to withdraw from benzodiazepines typically receive little advice or support, and such withdrawal should be by small increments over a period of months.Benzodiazepines are usually prescribed only short-term, as there is little justification for their prescribing long-term. Some doctors however, disagree and believe long-term use beyond 4 weeks is sometimes justified, although there is little data to support this viewpoint. Such viewpoints are a minority in the medical literature.There is no evidence that "drug holidays" or periods of abstinence reduced the risk of dependence; there is evidence from animal studies that such an approach does not prevent dependence from happening. Use of short-acting benzodiazepines is associated with interdose withdrawal symptoms.
Micafungin, sold under the brand name Mycamine, is an echinochandin antifungal medication used to treat and prevent invasive fungal infections including candidemia, abscesses, and esophageal candidiasis. It inhibits the production of beta-1,3-glucan, an essential component of fungal cell walls that is not found in mammals. Micafungin is administered intravenously. It received final approval from the U.S.  Food and Drug Administration (FDA) in March 2005, and gained approval in the European Union in April 2008. It is on the World Health Organizations List of Essential Medicines. Indications
Micafungin is indicated for the treatment of candidemia, acute disseminated candidiasis, Candida peritonitis, abscesses and esophageal candidiasis. Since January 23, 2008, micafungin has been approved for the prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplantation (HSCT). Micafungin works by way of concentration-dependent inhibition of 1,3-beta-D-glucan synthase resulting in reduced formation of 1,3-beta-D-glucan, which is an essential polysaccharide comprising one-third of the majority of Candida spp. cell walls. This decreased glucan production leads to osmotic instability and thus cellular lysis. Dosage
The metabolism of micafungin occurs hepatically via acryp sulfatase followed by secondary metabolism by a transferase. Precautions should be taken with regards to dosing, as micafungin weakly inhibits CYP3A4. Dosage forms
Micafungin is a natural antifungal product derived from other fungi as a defense mechanism for competition of nutrients, etc. To be specific, micafungin is derived from FR901379, and is produced by Coleophoma empetri. References
