Peringatan Keamanan

The cases of overdose with piracetam is rare. The highest reported overdose with piracetam was oral intake of 75g which was associated with diarrhea and abdominal pain; the signs were most likely related to the extreme high dose of sorbitol contained in the used formulation. In cases of acute, significant overdosage, stomach emptying by gastric lavage or induced emesis is recommended as there are no known antidotes for piracetam L1124. Management for an overdose will most likely be symptomatic treatment and may include hemodialysis, where the extraction efficacy of the dialyser is 50 to 60% for the drug L1124.

Oral LD50 in a mouse acute toxicity study was 2000 mg/kg MSDS.

Piracetam

small molecule approved investigational

Deskripsi

Piracetam is a nootropic drug in the racetams group, with chemical name 2-oxo-1-pyrrolidine acetamide. It shares the same 2-oxo-pyrrolidone base structure with pyroglutamic acid and is a cyclic derivative of the neurotransmitter ?-aminobutyric acid (GABA). However its mechanism of action differ from that of endogenous GABA. Piracetam has neuroprotective and anticonvulsant properties and is reported to improve neural plasticity A31532. Its efficacy is documented in cognitive disorders and dementia, vertigo, cortical myoclonus, dyslexia, and sickle cell anemia although the clinical application in these conditions is not yet established. Piracetam has effects on the vascular system by reducing erythrocyte adhesion to the vascular endothelium, hindering vasospasms and facilitating microcirculation A31532.

Originally marketed by UCB Pharma in 1971, piracetam was the first nootropic drug to modulate cognitive function without causing sedation or stimulation A31532. It is not approved for any medical or dietary use by the FDA. In the UK, piracetam is prescribed mainly for myoclonus, but is used off-label for other conditions such as learning difficulties in children, memory loss or other cognitive defects in the elderly, and sickle-cell vaso-occlusive crises L1124. Evidence to support its use for many conditions is unclear.

Profil Farmakokinetik

Waktu Paruh (Half-Life) The plasma half life of piracetam is approximately 5 hours following oral or intravenous administration. The half life in the cerebrospinal fluid was 8.5 hours [L1124].
Volume Distribusi Vd is approximately 0.6L/kg. Piracetam may cross the blood-brain barrier as it was measured in the cerebrospinal fluid following intravenous administration [L1124]. Piracetam diffuses to all tissues except adipose tissues, crosses placental barrier and penetrates the membranes of isolated red blood cells [L1124].
Klirens (Clearance) The apparent total body clearance is 80-90 mL/min [L1124].

Absorpsi

Piracetam displays a linear and time-dependent pharmacokinetic properties with low intersubject variability over a large range of doses. Piracetam is rapidly and extensively absorbed following oral administration with the peak plasma concentration is reached within 1 hour after dosing in fasted subjects. Following a single oral dose of 3.2 g piracetam, the peak plasma concentration (Cmax) was 84 µg/mL. Intake of food may decrease the Cmax by 17% and increase the time to reach Cmax (Tmax) from 1 to 1.5 hours. Tmax in the cerebrospinal fluid is achieved approximately 5 hours post-administration L1124. The absolute bioavailability of piracetam oral formulations is close to 100% and the steady state plasma concentrations are achieved within 3 days of dosing L1124.

Metabolisme

As large proportion of total piracetam administered is excreted as unchanged drug, there is no known major metabolism of piracetam L1124.

Rute Eliminasi

Piracetam is predominantly excreted via renal elimination, where about 80-100% of the total dose is recovered in the urine. Approximately 90% of the dose of piracetam is excreted in the urine as unchanged drug L1124.
