DICP : the annals of pharmacotherapy

Among the many advances made in intensive care therapeutics in recent years, few have rivaled the impact of mechanical ventilators. Their expanded use affects all who practice in the critical care setting. ⋯ A basic introduction is made into ventilator set up, weaning techniques, adjunctive drug therapy, and complications. The pharmacotherapy specialist who understands interactions between patients and ventilators, and the effects of mechanical ventilation on cardiopulmonary function will be best equipped to individualize drug therapy.

Improper inhalation technique with beta-agonist metered-dose inhalers (MDIs) decreases efficacy of the bronchodilator. The success of demonstrating the correct technique and the pharmacist's role in patient education has been reported. To obtain information regarding the routine patient education practice of pharmacists when dispensing a beta-agonist MDI (albuterol), the following study was performed. ⋯ No pharmacist asked the PI to perform the technique while he/she observed. No pharmacist offered information on delivery enhancement devices. Our results demonstrate that few pharmacists educate patients on the correct usage of an MDI, and that many pharmacists are not aware of the correct technique.

This study determined the total preparation time, cost, and contamination rate associated with preparing 50-mL admixtures of ranitidine 50 mg from each of the following commercial source vials: 50 mg/2 mL unit-dose vial (treatment A), 50 mg/2 mL 10 mL multidose vial (treatment B), and 50 mg/2 mL 40 mL multidose vial (treatment C). The study consisted of two separate phases: phase I extemporaneous compounding and phase II batch manufacturing. Twelve technicians prepared ten admixtures from each source vial during each phase. ⋯ Multidose vials saved approximately $197 per 200 admixtures. Drug and personnel costs were reduced when batch manufacturing with 40-mL multidose vials was compared with extemporaneous compounding with unit-dose vials. Our study showed that multidose vials decreased the total preparation time and cost for making ranitidine admixtures during both extemporaneous compounding and batch manufacturing by reducing setup time, preparation time, and drug procurement cost.

Anistreplase, a modified congener of streptokinase, is a recently approved thrombolytic agent used in the treatment of acute myocardial infarction (AMI). Clinical studies have demonstrated anistreplase to be equally efficacious as intracoronary streptokinase when given within four hours of the onset of chest pain. Thirty units, given as a single bolus intravenous injection, result in reperfusion rates of approximately 60-70 percent. ⋯ Anistreplase has two distinct advantages over both streptokinase and alteplase: (1) it can be administered as a single bolus intravenous injection and (2) it has a longer half-life which may result in decreased reocclusion rates. Anistreplase therapy is associated with reductions in both short- and long-term mortality and has been shown to preserve left ventricular function. A large, long-term, comparative clinical trial (Third International Study of Infarct Survival or ISIS-III) investigating morbidity and mortality rates with streptokinase, alteplase, and anistreplase is ongoing, as is a direct comparative study against alteplase alone (TEAM-3, Multicenter Thrombolytic Trials of Eminase in Acute Myocardial Infarction).

Randomized Controlled Trial Clinical Trial
A double-blind, placebo-controlled study of the efficacy of Lactinex in the prophylaxis of amoxicillin-induced diarrhea.
The disruption of the natural flora of the gastrointestinal tract (especially Lactobacillus acidophilus) may occur during antibiotic therapy. This may lead to diarrhea, dehydration, and electrolyte imbalances. It has been suggested that replacement of the lactobacilli with a commercially available product may prevent the diarrhea. ⋯ Lactinex or placebo was administered four times a day for ten days to coincide with the antibiotic therapy. The Lactobacillus preparation did not appear to consistently prevent diarrhea in this patient population. Patients' age, diet, and parental definition of diarrhea were factors that may have influenced the results.
