Crystals of dimenhydrinate as a model drug were used for crystal coating, a method that can be applied to increase the flowability of a material and facilitate the tablet making. An increase in particle size was observed during the film coating. The change in shape of the coated particles was also examined. Some physicochemical parameters changed during coating, e.g. the surface free energy parameters and the wetting of the samples. The amount of coating material (and therefore the coating time) influenced several parameters (the shape of the particles, the flow properties and surface free energy parameters, compressibility and compactibility). Several parameters of prepared tablet (porosity, breaking hardness) were examined. Accordingly, coating of the crystals can be performed in order to enhance the handling of a material with insufficient properties for tablet making.
In December 2001, the FDA required a "black box warning" suggesting that unexpected cardiovascular deaths could occur at normal therapeutic doses of droperidol. We reviewed data from 270 MedWatch reports, including 99 reports of death, submitted between November 1, 1997, and January 10, 2002. We further reviewed primary reports of deaths and cardiovascular adverse events associated with < or = 10 mg of droperidol. There were 99 death reports representing 89 patients, with a specified dose in 66 cases. Among 74 (83%) foreign fatality reports, 57 included a known dose (> or = 50 mg in 29 cases [49%] and < or = 2.5 mg in only 3 cases [5%]). Of the 15 (17%) U.S. cases, 9 included a specified dose (< or = 2.5 mg in 5 cases and 5-10 mg in 4 cases). Cardiovascular deaths after therapeutic doses (< or = 2.5 mg) of droperidol are rare. Mandatory electrocardiographic screening appears unnecessary.
The majority of North American pregnant women experience some degree of nausea and vomiting, usually in the first few months of pregnancy. Women utilize many coping strategies, including self-treatment with herbal medicine and other alternative therapies. In a qualitative study of self-care in pregnancy, birth and lactation within a non-random sample of 27 women in British Columbia, Canada, 20 women (74%) experienced pregnancy-induced nausea. Ten of these women used anti-emetic herbal remedies, which included ginger, peppermint, and Cannabis. The safety and efficacy of each of these herbal remedies is discussed here. Only ginger has been subjected to clinical trials among pregnant women, though all three herbs were clinically effective against nausea and vomiting in other contexts, such as chemotherapy-induced nausea and post-operative nausea. While safety concerns exist in the literature for all three herbs with regards to their use by pregnant women, clinical evidence of harm is lacking.
