  • Guideline for Preoperative Medication Management
    Guideline: Preoperative Medication Management Guideline for Preoperative Medication Management Purpose of Guideline: To provide guidance to physicians, advanced practice providers (APPs), pharmacists, and nurses regarding medication management in the preoperative setting. Background: Appropriate perioperative medication management is essential to ensure positive surgical outcomes and prevent medication misadventures.1 Results from a prospective analysis of 1,025 patients admitted to a general surgical unit concluded that patients on at least one medication for a chronic disease are 2.7 times more likely to experience surgical complications compared with those not taking any medications. As the aging population requires more medication use and the availability of various nonprescription medications continues to increase, so does the risk of polypharmacy and the need for perioperative medication guidance.2 There are no well-designed trials to support evidence-based recommendations for perioperative medication management; however, general principles and best practice approaches are available. General considerations for perioperative medication management include a thorough medication history, understanding of the medication pharmacokinetics and potential for withdrawal symptoms, understanding the risks associated with the surgical procedure and the risks of medication discontinuation based on the intended indication. Clinical judgement must be exercised, especially if medication pharmacokinetics are not predictable or there are significant risks associated with inappropriate medication withdrawal (eg, tolerance) or continuation (eg, postsurgical infection).2 Clinical Assessment: Prior to instructing the patient on preoperative medication management, completion of a thorough medication history is recommended – including all information on prescription medications, over-the-counter medications, “as needed” medications, vitamins, supplements, and herbal medications. Allergies should also be verified and documented.

  • Alpha Blockers
    Alfuzosin, Silodosin, Tamsulosin/Clinically Uroselective Alpha1-Adrenergic Blockers: Recommendations for Use October 2010 VA Pharmacy Benefits Management Services, Medical Advisory Panel, and VISN Pharmacist Executives The product information should be consulted for detailed prescribing information. Issue Is there a preference to using a clinically uroselective alpha1-adrenergic blocker over a non-uroselective alpha1-adrenergic blocker for the management of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Background Of the available non-uroselective alpha1-adrenergic blockers, doxazosin, prazosin, and terazosin are listed on the VA National Formulary (VANF); alfuzosin, silodosin, and tamsulosin are considered clinically uroselective alpha1-blockers , of which tamsulosin is available on the VANF for use in patients with LUTS due to BPH. Summary of Clinical Evidence1-6 All alpha1-blockers have been shown to improve LUTS associated with BPH (recommended doses for BPH are doxazosin 4 to 8mg once daily, prazosin 2mg twice daily, terazosin 5 to 10mg once daily; lower doses have also been effective) although the American Urological Association (AUA) guidelines for BPH state there are insufficient data to support the use of prazosin in BPH. There is no evidence that alfuzosin, silodosin, or tamsulosin provide benefit in patients who have not responded to an adequate trial with a non-uroselective alpha1-blocker. It is unknown whether the clinically uroselective alpha1-blockers offer an advantage in patients who are at risk for falls. Based on meta-analyses by the AUA, alfuzosin and tamsulosin were found to have significantly less dizziness than terazosin but not doxazosin. In addition, the change in blood pressure with doxazosin or terazosin has been found to be clinically insignificant in patients with BPH who are either normotensive or have hypertension (HTN) that is well-controlled with pharmacologic agents.
