Purpose Since 2018, several pegfilgrastim biosimilars were approved, which may affect insurance reimbursement. Guidelines recommend pegfilgrastim be administered the days following chemotherapy to prevent hematopoietic toxicity. To date, only the reference pegfilgrastim product has an available autoinjector-device. This has contributed to logistical issues in administering biosimilar agents per guideline recommendations. Administration on the same day as chemotherapy may be a potential alternative when logistical issues are present. This review will assess current evidence on this practice to inform clinical decisions. Data sources: A comprehensive literature search was performed in PubMed/Medline for studies examining the administration of pegfilgrastim on the same day as chemotherapy. Data summary: Several studies were identified, including a systematic review, retrospective reviews, and insurance claim data. Studies had significant limitations, and chemotherapy regimens and cancer types varied among studies. Studies showed inconsistent results in terms of incidence, duration, and severity of febrile neutropenia. In studies with patients with head and neck, urothelial, gynecologic, gastrointestinal, and prostate cancer, no difference in outcomes was detected or outcomes supported the feasibility of same-day administration. In patients with breast cancer, outcomes were worse with same-day administration. Outcomes were mixed in studies with non-Hodgkin’s lymphoma, non-small cell lung cancer, and various solid tumors. Conclusion Administration of pegfilgrastim on the same day as chemotherapy may be safe and an acceptable alternative, if logistics prohibit a patient from receiving administration the days after chemotherapy. Clinicians should consider patient risk factors and prescribed chemotherapy regimens, along with available evidence when contemplating administration of same-day pegfilgrastim.

Purpose To provide pharmacists with an overview of ocular viscosurgical devices (OVDs) and a comprehensive resource describing characteristics of commercially available agents. Summary OVDs are substances that are injected into the eye during ophthalmic procedures, such as cataract surgery, to reduce injury to the endothelium that may result from surgical manipulation. Currently available OVDs are composed of one or more of the following active ingredients: sodium hyaluronate, sodium chondroitin sulfate, and hydroxypropylmethylcellulose. Rheologic properties of OVDs, such as viscosity, elasticity, pseudoplasticity, and cohesion, affect the products’ function and performance. Based on rheologic properties, OVDs can be generally classified as cohesive or dispersive. Given each products’ unique characteristics, OVDs are not interchangeable. An understanding of OVD characteristics and role in practice allows for improved product selection, which varies based on patient characteristics and procedure. Availability of OVD information and literature is generally lacking since OVDs are regulated by the US Food and Drug Administration (FDA) as medical devices. This primer includes an overview of relevant ophthalmic surgical practices and the landscape of comparative efficacy and safety literature to assist in formulary decision-making. This review also provides a comprehensive guide to commercially available OVDs and a discussion on practical considerations for the pharmacist. Conclusion Pharmacists may be tasked with handling OVDs in institutional settings. Knowledge about OVD rheologic properties, product characteristics, role in practice, and available literature is necessary for managing formularies and ensuring optimal product selection.

In July 2018, the National Guideline Clearinghouse lost funding, leaving fewer freely available online guideline collections. Based on the authors’ experience of the 3 major guideline-focused databases that are currently available (Guidelines International Network, the Turning Research into Practice database, and Guideline Central) an easy to use resource with stringent inclusion criteria is currently lacking, though new resources are in development. These 3 resources vary in scope, and none stood out as an all-encompassing favorite. Regardless of the source used to find and access guidelines, clinicians must evaluate guideline quality and currency before using them in clinical practice.
