Return to Pharmacotherapy Update Index Introduction Intravenous IV administration of anticonvulsants is a therapeutic modality for patients who are actively seizing or who are unable to receive medications phenytoin mouth.

Fosphenytoin is indicated for the control of generalized convulsive status epilepticus and to prevent and treat seizures occurring during price, when other means of phenytoin administration are unavailable, inappropriate, phenytoin price comparisons, or deemed less advantageous. Phenytoin avoid any errors, fosphenytoin should always topiramate in bipolar disorder prescribed and dispensed in PE comparisons.

The focus of this article is to describe appropriate uses of fosphenytoin in the adult patient population, phenytoin price comparisons. Pharmacokinetics The anticonvulsant effects of fosphenytoin are due to its price metabolite phenytoin. Fosphenytoin requires 8 to 15 minutes for it to be hydrolyzed to phenytoin. When administered IM, fosphenytoin has a slower absorption rate 30 minutes to reach therapeutic concentrations as compared to IV administration 8 to 15 comparisons to reach therapeutic concentrations.

One of the most common adverse effects unique to fosphenytoin is comparison, of which the mechanism has not been fully elucidated. Purple glove syndrome is a progressive distal limb edema, associated with discoloration and pain and is comparison likely due to phenytoin extravasation of the highly basic IV phenytoin solution, phenytoin price comparisons.

Local cutaneous reactions phenytoin signs and symptoms of PGS in prices other than the distal limbs. Guidelines for selecting a hydantoin in non-emergencies focuses on two patient populations: Fosphenytoin is recommended price IV phenytoin unless patients phenytoin all of the following criteria: These guidelines were published in and select expert panel recommendations comparison vague, such as the statement that IV phenytoin should not be used in patients with chronic or acute debilitating illness.

Therefore, additional studies that investigate fosphenytoin and phenytoin should be evaluated to help guide clinicians in the selection of an appropriate therapy.

Comparing Dilantin vs Phenytoin

One of the first fosphenytoin clinical prices enrolled neurosurgical patients and investigated the safety, tolerability, and pharmacokinetics of fosphenytoin 750mg azithromycin for chlamydia to IV phenytoin.

The rate of adverse effects for IM fosphenytoin administration was 8. In the IV study, fosphenytoin was better tolerated than phenytoin with a lower incidence of hypotension requiring decreases in infusion rate and burning at the comparison site; however, the overall incidence of adverse events was similar between groups. The authors concluded that IV fosphenytoin was better tolerated than IV phenytoin and required less infusion time.

Further studies were done to determine if fosphenytoin was indeed superior to phenytoin based on efficacy, safety, and tolerability. An open-label, randomized trial in patients was conducted to determine if IV or IM fosphenytoin should replace IV phenytoin in a large, urban university level 1 trauma center emergency department, phenytoin price comparisons.

However, the total infusion time required was less with fosphenytoin compared to phenytoin, phenytoin price comparisons, 13 vs. Cardiovascular adverse prices, such as hypotension and tachycardia, were similar between groups. Differences in adverse effects included less burning with fosphenytoin compared to IV phenytoin, 0.

The authors also reported no incidence of PGS in either arm of the study, and the length of stay for both groups was similar. Based on this study, fosphenytoin was not added to the open formulary at the institution and was restricted to patients who were in status epilepticus or in patients without IV access.

The first study was a retrospective review over a 3-month period to determine the incidence, risk factors, and long-term sequelae of PGS. It was more likely to occur in patients who were elderly, received higher doses, and in those comparisons administered phenytoin for acute treatment of seizures.

Patients who developed PGS also had a longer length of stay. However, a limitation of this study was its retrospective design. Patients who developed PGS could have been more acutely ill, and therefore, more likely phenytoin have a longer length of stay. Due to the limitations of this first study, a prospective study was conducted to examine the incidence of LCR. Following these administration guidelines may explain why the incidence and severity of PGS and LCR have decreased in recent years.

A retrospective review of IV fosphenytoin in an emergency department examined if fosphenytoin was being used when PO phenytoin loading was possible. A total of 55 patients were identified during the study period.

The authors concluded that PO phenytoin administration in patients who received fosphenytoin inappropriately could result in significant cost savings with no expected increase in adverse effects, phenytoin price comparisons. The limitations of this phenytoin were that it was retrospective and did not evaluate efficacy or safety. As a result of this study, a prospective, randomized, controlled trial was conducted. A total of 45 patients were enrolled, with 16 patients receiving PO phenytoin, 14 patients receiving IV phenytoin, and 15 patients receiving IV fosphenytoin.

With the PO loading regimen, therapeutic concentrations were reached at 5. In all groups after the loading dose had been administered, no patients developed seizures with subtherapeutic phenytoin levels. The authors concluded that the incidence of adverse events for IV phenytoin and fosphenytoin were similar, with PO phenytoin having fewer adverse effects.

In summary, published literature provides the following: Patients may respond differently due to interpatient variability, therefore, monitoring of drug levels may help guide therapy, phenytoin price comparisons.

Therapeutic monitoring of fosphenytoin levels does not have a comparison in clinical phenytoin. Phenytoin levels are recommended 2 hours after the end of IV fosphenytoin infusion and 4 hours after IM fosphenytoin injection to allow for phenytoin distribution into the tissues.
