With intravenous use in adults: In pharmacology, the volume of distribution (V D, also known as apparent volume of distribution, literally, volume of dilution [1]) is the theoretical volume that would be necessary to contain the total amount of an administered drug at the same concentration that it is observed in the blood plasma
Jul 24, 2023 · The volume of distribution (Vd) is a pharmacokinetic parameter representing an individual drug’s propensity to either remain in the plasma or redistribute to other tissue compartments

It is available in various formulations: • oral formulations (tablets of 2 and 4 mg, a modified-release tablet of 4 or 8 mg, and a syrup 5 mg/ml); • a multidose pressurized aerosol, which delivers 100 micrograms per puff; • Dosage Side effects Interactions What is salbutamol? Salbutamol (albuterol) is a medication used to relax and open up your airways
