Off-label use of intravenous antimicrobials for inhalation in patients with cystic fibrosis.

Management of infections in patients with cystic fibrosis (CF) presents challenges for healthcare providers, including the eradication of initial acquisition, treatment of acute exacerbations, and chronic infection with suppressive therapy. Inhaled antimicrobial therapy for infections in patients with CF has been used in these capacities, often in an effort to achieve optimal concentrations in sputum for antimicrobial efficacy while mitigating potential toxicities associated with systemic therapy. Unfortunately, there are few commercially available products formulated for inhalation, resulting in the off-label use of other formulations, such as intravenous products, administered via nebulization. This review aims to examine the evidence supporting the efficacy of these off-label formulations for management of acute and chronic infections associated with CF, as well as adverse effects associated with their use.

Safety of Rectal Administration of Acetaminophen in Neonates.

BACKGROUND: On the basis of pharmacokinetic modelling, high-dose acetaminophen by rectal administration has been recommended for neonates needing antipyretic or analgesic therapy, but the safety and efficacy of this approach have not been established in vivo. OBJECTIVES: The primary objective was to assess the safety of rectal acetaminophen administration for neonates, as indicated by changes in the results of hepatic and renal function tests. The secondary objective was to assess the efficacy of rectal acetaminophen administration in terms of the Premature Infant Pain Profile-Revised (PIPP-R) score. METHODS: This single-centre retrospective chart analysis was conducted in the neonatal intensive care unit at a quaternary care children's hospital. Neonates who received all prescribed doses of acetaminophen by continu - ous rectal administration for 24 h or more, from January 1, 2011, to December 31, 2012, were included. For the primary objective, hepatotoxicity was assessed in terms of changes in liver enzyme levels, and nephrotoxicity was assessed in terms of changes from baseline serum creatinine values. RESULTS: Twenty-five patients, who received a total of 27 courses of acetaminophen by rectal administration, met the inclusion criteria. Median gestational age at initiation of acetaminophen was 37.0 weeks (interquartile range 35.0-39.8 weeks). Values of alanine aminotransferase remained within normal limits during acetaminophen therapy for all but 3 patients, for whom the changes were attributable to confounding factors. Renal function remained unchanged. The secondary outcome of efficacy (based on PIPP-R score) could not be evaluated because of concurrent use of opioids for most patients. CONCLUSIONS: Continuous rectal administration of acetaminophen over a short period (< 48 h) appeared to be well tolerated. The conclusions that can be drawn from these results are limited because of small sample size, the prescribing of doses lower than those recommended by the hospital's formulary, and limited blood sampling. Further studies are required.

CONTEXTE: Selon une modélisation pharmacocinétique, des doses élevées d'acétaminophène administré par voie rectale ont été recommandées comme traitement antipyrétique ou analgésique chez le nouveau-né, mais l'innocuité et l'efficacité de cette modalité d'administration n'ont pas été établies in vivo. OBJECTIFS: L'objectif principal était d'évaluer l'innocuité de l'acétaminophène administré par voie rectale chez le nouveau-né en observant les changements dans les résultats des bilans hépatique et rénal. L'objectif secondaire était d'évaluer l'efficacité de l'acétaminophène administré par voie rectale à l'aide du score obtenu dans le Premature Infant Pain Profile-Revised (PIPP-R). MÉTHODES: La présente étude rétrospective menée dans un seul centre comportait une analyse des dossiers médicaux de patients admis à l'unité de soins intensifs néonatals d'un établissement de soins quaternaires pour enfants. Les nouveau-nés ayant reçu toutes les doses prescrites d'acétaminophène par administration rectale ininterrompue pendant 24 heures ou plus, entre le 1er janvier 2011 et le 31 décembre 2012, étaient admissibles à l'étude. Pour l'objectif principal, l'hépatotoxicité a été évaluée en fonction des variations observées dans les taux d'enzymes hépatiques et la néphrotoxicité a été évaluée en fonction des changements observés dans la créatininémie par rapport aux valeurs de départ. RÉSULTATS: Vingt-cinq patients qui ont reçu un total de 27 traitements par acétaminophène administré par voie rectale répondaient aux critères d'inclusion. L'âge gestationnel médian lors de l'amorce du traitement par acétaminophène était de 37,0 semaines (écart interquartile de 35,0 semaines à 39,8 semaines). Les valeurs d'alanine-aminotransférase demeuraient à l'intérieur des limites normales pendant le traitement par acétaminophène pour tous les patients à l'exception de trois pour lesquels les changements étaient attribués à des facteurs de confusion. La fonction rénale demeurait inchangée. Le critère d'évaluation secondaire quant à l'efficacité (s'appuyant sur le score obtenu dans le PIPP-R) n'a pu être évalué en raison de la prise concomitante d'opioïdes chez la plupart des patients. CONCLUSIONS: L'administration rectale ininterrompue d'acétaminophène pendant une courte période (moins de 48 heures) semblait être bien tolérée. Cependant, les conclusions qui peuvent être tirées de ces résultats sont limitées en raison de la petite taille de l'échantillon, de la prescription de doses plus faibles que celles recommandées dans la liste des médicaments de l'hôpital et de l'insuffisance des échantillons sanguins. De plus amples études sont nécessaires.

A Pilot Project for Clinical Pharmacy Services in a Clinic for Children With Medical Complexity.

OBJECTIVE: The primary objective of the project was to assess the impact of clinical pharmacy services in a clinic for children with medical complexity. Secondary objectives were to identify and characterize the drug-related needs of these patients and to describe and develop the role of a pharmacist in the clinic. METHODS: This was a prospective descriptive study in which a clinical pharmacist staffed the clinic for children with medical complexity for 11 weeks, from January to March 2011. This allowed for the collection of baseline data, such as patient characteristics and measurements of pharmacist workload and assessment (eg, types of drug therapy problems, medication reconciliation, medication teaching). RESULTS: A pharmacist participated in 46 clinic visits with 43 patients, identifying a total of 42 drug therapy problems. Of the 42 problems, 35 actual and 7 potential drug problems were identified, resulting in approximately 1 problem per patient. The most common actual problems included "dose too small" (37.1%) and "patient requires a medication for untreated condition" (20%). Common potential problems included "drug interactions" (43%) and "adverse effects" (57%). CONCLUSIONS: The pilot study demonstrates that children with medical complexity are at high risk for drug therapy problems and the presence of a clinic pharmacist is beneficial in the identification, prevention, and resolution of drug therapy problems, while helping ensure continuity of care in this population.
