Fluphenazine decanoate half life

The decanoate produces an early high peak which occurs during the first day and then declines with an apparent half-life ranging from 6.8 to 9.6 days following a single injection. After multiple injections of fluphenazine decanoate, however, the mean apparent half-life increases to 14.3 days, and the time to reach steady-state is 4 to 6 weeks Fluphenazine decanoate have a half-life of 14 days, however, the longer time the treatment, the longer the apparent half-life, suggesting to reduce the dose or to enlarge the dosing interval Plasma half-life of fluphenazine after a single dose was 14.7 hours in 1 patient given hydrochloride by mouth and 14.9 and 15.3 hours in 2 patients given hydrochloride by intramuscular injection. Half-life was 3.6 and 3.7 days in 2 patients given enanthate intramuscularly and 9.6 and 6.8 days in 2 patients given the decanoate intramuscularly

Fluphenazine decanoate is recommended to be dosed at 12.5-25 mg initially although a conversion ratio has been calculated at 1.6 times the daily oral dose being equivalent to the intramuscular fluphenazine decanoate requirement in mg/week but this conversion is rarely utilized. 10. Clearanc The limitation of fluphenazine decanoate is the 2-week injection schedule, the higher incidence of local site reactions from the sesame oil vehicle, and the greater risk for neurological adverse effects than with atypical antipsychotics Reference Jann, Ereshefsky and Saklad 23; however, LAI fluphenazine has a favorable metabolic profile.

Fluphenazine has an incomplete oral bioavailability of 40% to 50% (due to extensive first pass metabolization in the liver). Its half life is 15 to 30 hours. Dosing [edit | edit source] 12.5 mg of fluphenazine decanoate is roughly equivalent to 100 mg of zuclopenthixol decanoate or 20 mg of flupentixol decanoate. Side effects [edit | edit source Mean pre-dose haloperidol levels changed little after week 8. Results suggested an absorption half-life of 4 weeks, although, in three cases steady state was only achieved after 11 monthly injections. Steady state levels of both haloperidol and fluphenazine correlated highly with dose The half-life of fluphenazine is formulation-dependent. (The decanoate is 5 to 12 days; the hydrochloride 12 to 60 hours.) Fluphenazine is also used to alleviate pain and in childhood development disorders.

The elimination half-life of fluphenazine decanoate is 6.8-9.6 days after a single injection and increases to at least 14 days after multiple injections Absorption half-life duration and absorption half-life variability are key concepts in LAI dosing. LAI options Fluphenazine decanoate is an older, inexpensive LAI with considerable interpatient variability in absorption rate and peak effects, and a relatively short duration of action. Dosing every 7 days may be necessary to avoid peak. • Fluphenazine decanoate is available as an LAI in sesame oil. • Plasma levels peak within 24 h of intramuscular injection • Half-life is approximately 7-14 days. • Plasma levels obtained vary up to 40-fold in patients receiving the same dose. • Smoking significantly reduces plasma fluphenazine levels. 11 12 6,6 Fluphenazine Decanoate.

It belongs to the piperazine class of phenothiazines and is extremely potent; more potent than haloperidol and around fifty to seventy times the potency of chlorpromazine Fluphenazine is a phenothiazine-type antipsychotic that is also a potent D2 receptor antagonist; it has some affinity for histamine-1, alpha-1, and muscarinic-1 receptors, which may cause sedation, orthostasis, and anticholinergic effects (e.g., dry mouth, constipation) for patients. 3 Fluphenazine decanoate is usually dosed once every 2 to 3. 3-12 years: 0.5 mg/day PO initially; dose increased PRN by 0.5 mg every 5-7 days until therapeutic effect achieved, then reduced to lowest effective maintenance level of 0.05-0.075 mg/kg/day PO divided q8-12hr.
