Biological Activity

Description Methocarbamol (AHR 85) is a carbonic anhydrase inhibitor, used as a central muscle relaxant to treat skeletal muscle spasms.
In vitro
In vitro Methocarbamol is metabolized via dealkylation and hydroxylation followed by conjugation to form both glucuronides and sulfates. [1]
In Vivo
In vivo Methocarbamol results in a median terminal half-life, mean transit time, mean absorption time, and apparent oral clearance of 2.89 hours, 2.67 hours, 0.410 hours, and 16.5 mL/min/kg in the horse. Methocarbamol is rapidly absorbed and extensively metabolized after oral administration to horses as indicated by a short absorption time and modest systemic bioavailability of 54.4% in the horse. [1] Methocarbamol is a centrally acting muscle relaxant available in both IV and oral forms in cats. [2] Methocarbamol (100 mg/kg) does not change the heart rate, cardiac output, mean pulmonary arterial blood pressure, systolic, diastolic and mean aortic blood pressure, respiratory rate and arterial blood gases, but mild to moderate depression is observed in five of eight horses administered i.v. Methocarbamol, and in all horses administered oral Methocarbamol. Plasma Methocarbamol concentration declines very rapidly during the initial or rapid disposition phase after i.v. administration; the terminal elimination half-life ranged from 59 minutes to 90 minutes in horse. Peak plasma Methocarbamol concentrations following oral administration occur within 15 to 45 minutes in horse. [3]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
