This survey aimed to examine how patient-pharmacist communication using the drug profile book relates patient's behavior regarding its use. Among patients who visited one of the five pharmacies during the 4 months between July and October of 2013, 245 patients who had been prescribed antihypertensives were asked to complete a questionnaire. ⋯ Response rates of "frequency of bringing the drug profile book", "sense of utility", and "experience of showing the drug profile book to the physician" in the group with "experience of being questioned while showing the drug profile book" were significantly higher than those in the group without such experience. This survey indicated that experience of being questioned by a pharmacist while showing the drug profile book related patient's behavior regarding its use.

Teicoplanin, a glycopeptide antibiotic for methicillin-resistant Staphylococcus aureus, is recommended for therapeutic drug monitoring during treatment. Maintaining a high trough range of teicoplanin is also recommended for severe infectious disease. However, the optimal dose and interval of treatment for severe renal impairment is unknown. ⋯ Plasma teicoplanin trough levels were maintained at a high range (20-30 μg/mL). Although the patient required long-term teicoplanin treatment, a further decline in renal function was not observed, and blood culture remained negative after the start of treatment. Teicoplanin treatment that is maintained at a high trough level by therapeutic drug monitoring might be beneficial for severe methicillin-resistant Staphylococcus aureus infection accompanied by renal impairment.

Peripheral neuropathy is a common adverse effect of paclitaxel and oxaliplatin treatment. The major dose-limiting side effect of these drugs is peripheral sensory neuropathy. The symptoms of paclitaxel-induced neuropathy are mostly sensory and peripheral in nature, consisting of mechanical allodynia/hyperalgesia, tingling, and numbness. ⋯ This review describes that (1) paclitaxel-induced neuropathic pain may be the result of up-regulation of TRPV1 in small- and medium-diameter DRG neurons. In addition, paclitaxel treatment increases the release of substance P, but not calcitonin gene-related peptide, in the superficial layers of the spinal dorsal horn. (2) TRPA1 expression via activation of p38 mitogen-activated protein kinase in small-diameter DRG neurons, at least in part, contributes to the development of oxaliplatin-induced acute cold hyperalgesia. We suggest that TRPV1 or TRPA1 antagonists may be potential therapeutic lead compounds for treating anticancer drug-induced peripheral neuropathy.

The Japanese Ministry of Health, Labor, and Welfare lists hand-foot syndrome as a serious adverse drug event. Therefore, we evaluated its association with anticancer drug therapy using case reports in the Japanese Adverse Drug Event Report (JADER) and the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). In addition, we calculated the reporting odds ratio (ROR) of anticancer drugs potentially associated with hand-foot syndrome, and applied the Weibull shape parameter to time-to-event data from JADER. ⋯ Adverse event symptoms of hand-foot syndrome were observed with most anticancer drugs, which carry warnings of the propensity to cause these effects in their drug information literature. The time-to-event analysis using the Weibull shape parameter revealed differences in the time-dependency of the adverse events of each drug. Therefore, anticancer drugs should be used carefully in clinical practice, and patients may require careful monitoring for symptoms of hand-foot syndrome.

Falls are common in elderly patients and are often serious. Several drugs have been associated with an increased risk of fall. Older adults often take multiple drugs for chronic diseases, and thus may be at increased risk from drugs associated with fall. ⋯ The probability of falling increased when the patients used zolpidem [odds ratio (OR)=2.47; 95%CI: 1.09-5.63; p<0.05] and calcium channel antagonists (OR=0.299; 95%CI: 0.13-0.68; p<0.01), and was also related to physical factors (OR=2.27; 95%CI: 1.01-5.09; p<0.05). Elderly patients taking zolpidem may fall due to sleepiness, and blood pressure control may be important to prevent orthostatic high blood pressure. In the treatment of elderly people, medical staff should try to choose drugs that prevent fall or are not associated with falling.
