A Route of administration in pharmacology and toxicology is the path by which a drug, fluid, poison, or other substance is taken into the body. Routes of administration are generally classified by the location at which the substance is applied. Common examples include oral and intravenous administration.

  ►  Route of administration : IV, rectal,

Dosing of Medicine differ in Adult & Pediatrics ↓


Adult Dose

S.No Ailment   Route   Dose Min   Dose Max   Unit   Dosage Form   Frequency   Additional Info
1 Sedation IV infusion 5 micrograms/kg/min Injection
2 Induction of anaesthesia rectal 6.5 mg/kg Dose: Given in patients at risk for hypotension.
3 Induction of anaesthesia IV infusion 0.2 0.6 mg/kg Injection Dose: Given in patients at risk for hypotension.
4 Induction of anaesthesia Injection etomidate is available as a conventional or an emulsion injection formulation. The usual dose is 300 micrograms/kg of etomidate given slowly, preferably into a large vein in the arm, although a lower dose of 150 micrograms/kg of the emulsion formulation may be sufficient. An initial dose of 150 to 200 micrograms/kg is recommended in the elderly, subsequently adjusted according to effects.

  ►    Mechanism of Drug Drug Interaction :  Sensitisation of the myocardium to beta-adrenergic stimulation occurs with some anaesthetics and ventricular fibrillation may occur if sympathomimetics such as adrenaline and isoprenaline are also used. Enhanced hypotensive effects may result when anaesthetics are given with ACE inhibitors, tricyclic antidepressants (which may also increase the risk of arrhythmias), MAOIs, antihypertensives, antipsychotics, or beta blockers A reduced dose of etomidate may be necessary in patients who have received antipsychotics, sedatives, or opioids. The hypnotic effect of etomidate has been potentiated by other sedative drugs. ,

►  Contraindication : Epilepsy,

  ►  Mechanism of Action :   A variety of ligand-gated ion channels, receptors and signal transduction proteins are modulated by general anesthetics.Chloride channels gated by the inhibitory GABA A receptors are sensitive to clinical concentrations of a wide variety of anesthetics, including etomidate. The capacity of propofol and etomidate to inhibit the response to noxious stimuli is mediated by a specific site on the β subunit of the GABA A receptor, whereas the sedative effects of these anesthetics are mediated by the same site on the β subunit.These results indicate that two components of anesthesia can be mediated by GABA A receptors,
