Fresofol Introduction
Fresofol is an intravenously administered short-acting anesthetic agent used for induction and maintenance of general anesthesia and for procedural sedation. It is a clear and colorless, oil-in-water emulsion supplied in a single-use, premixed form for intravenous administration.Uses for Fresofol
Fresofol is used to induce and maintain anesthesia, along with the adjuncts of nitrous oxide and oxygen. It is also used for sedation and treatment of status epilepticus.Mechanism of Action
Fresofol works primarily by binding to and activating the gamma-aminobutyric acid (GABA) receptor complex. This increases chloride ion conductance, resulting in a hyperpolarization of the cell membrane, which decreases neuronal hyperexcitability and leads to sedation and decreased muscle tone.How Long Does It Take to Work
Fresofol starts working immediately when it is administered intravenously. Its effects can last for a few minutes or several hours depending on the amount administered, the person's sensitivity to the drug, and the other medications given.Absorption
Fresofol is administered intravenously and is not absorbed after oral administration.Route of Elimination
Fresofol is metabolized primarily by the liver prior to excretion via the kidneys. Approximately 70% of the drug is excreted in the urine with the remainder being eliminated via the bile.Dosage
The recommended dose of propofol for induction of general anesthesia is 1.5 to 2.5 mg/kg body weight injected slowly over 20 to 40 seconds. Maintenance doses may be administered as required; however, 0.5 to 1.0 mg/kg body weight should not be exceeded. Intravenous bolus doses of propofol may be given in increments of 0.5 to 1 mg/kg of body weight.Administration
Fresofol may be administered intravenously by slow injection over 20 to 40 seconds. It is also available as an intravenous infusion and may be used for anaesthesia or sedation. In adults, the infusion rate should not exceed 50 to 75 mg/kg/h. In paediatrics, the infusion rate should not exceed 4 mg/kg/min.Side Effect
Common side effects associated with propofol use may include injection site pain, hypotension, bradycardia, dizziness, headache, tachycardia, nausea, and vomiting. Other side effects such as yellowing of the skin and eyes (jaundice), evidence of infection at the injection site, or difficulty breathing should be reported to a doctor immediately.Toxicity
Fresofol is generally well tolerated in low doses. However, at higher doses or with prolonged use propofol can accumulate in the body resulting in an increased risk of toxicity, which may include respiratory depression, hypotension (low blood pressure), arrhythmia, and heart failure.Precaution
Before using propofol, it is important to tell your doctor if you have any allergies or if you have any other medical conditions such as heart problems, asthma, liver or kidney disease, or if you are pregnant or breastfeeding.Interaction

Fresofol should be administered in an intravenous infusion and the rate of infusion should not exceed 50 to 75 mg/kg/h in adults and 4 mg/kg/min in pediatrics. The maximum total dose should not exceed 2 mg/kg of body weight.Storage Condition
Fresofol should be stored at a controlled room temperature between 25 degrees Celsius and 30 degrees Celsius and should not be frozen. It should also be stored away from direct sunlight, inquire or extreme temperatures.Volume of Distribution
The volume of distribution of propofol is approximately 0.7 to 1.5 L/kg.Half Life
The half-life of propofol is approximately 1.5 to 2.5 hours.Clearance
