The Accreditation Council for Pharmacy Education and the Canadian Council for Accreditation of Pharmacy Programs state that their respective programs should provide a curriculum appropriate to produce general practitioners of pharmacy. Millions of prescriptions are written for infants and children each year, and relatively few pharmacists practice in environments devoid of pediatric patients. To fulfill the stated mandate, professional pharmacy curricula must include adequate content dedicated to pharmaceutical care of the pediatric patient. ⋯ Pharmaceutical care of pediatric patients can also be improved by offering pediatric rotations to all pharmacy practice residents and encouraging their participation. However, a change in attitude may be most important. The contention that pediatric pharmacy practice is an isolated subspecialty can no longer be supported.

To evaluate the pharmacodynamics of four intravenous antimicrobial regimens-ceftriaxone 1 g, gatifloxacin 400 mg, levofloxacin 500 mg, and levofloxacin 750 mg, each every 24 hours-against recent Streptococcus pneumoniae isolates. ⋯ Ceftriaxone maintained high probability of target attainment over a broad range of pharmacodynamic targets regardless of penicillin susceptibility (%T > MIC 0-60%). Levofloxacin 500 mg maintained high probability of target attainment for AUC:MIC ratios 0-30; whereas, levofloxacin 750 mg and gatifloxacin maintained high probability of target attainment for AUC:MIC ratios 0-60. Rate of decline in the pharmacodynamic curve was most pronounced for the two levofloxacin regimens and more gradual for gatifloxacin and ceftriaxone.

The literature concerning the efficacy and safety of ketamine for conscious sedation during procedures in pediatric emergency departments was reviewed. Data were obtained from the Guidelines for Monitoring and Management of Pediatric Patients During and After Sedation for Diagnostic and Therapeutic Procedures developed by the American Academy of Pediatrics Committee on Drugs, and from a MEDLINE search (January 1966-July 2004). Search terms were conscious sedation, ketamine, and emergency department; articles relevant to pediatric age group were selected. ⋯ The main adverse effects of ketamine were emesis, recovery agitation, and emergence phenomena. Ketamine appears to be an effective and well-tolerated agent for conscious sedation in pediatric patients. Overall physician and parent satisfaction with the administration of this agent for conscious sedation was high.

Ziconotide is a novel peptide that blocks the entry of calcium into neuronal N-type voltage-sensitive calcium channels, preventing the conduction of nerve signals. N-type calcium channels are present in the superficial laminae of the dorsal horn of the spinal cord. In various animal models of pain, intrathecal administration of ziconotide blocked nerve transmission and nociception. ⋯ Drug trials of external intrathecal catheters and microinfusion devices demonstrated a 3% risk of meningitis. A low initial infusion rate of 0.1 microg/hour and limiting infusion rate increases to 2-3 times/week are now recommended. Patients responsive to intrathecal ziconotide require an implanted infusion system to receive long-term therapy.
