Almitrine decreases the open probability of Ca2+-dependent K+ channels with a high conductance (152±13 pS) in order to reduce their activity. This effect has an IC50 value of 0.22 μM. GH3 cells were found to exhibit the inhibitory action of Almitrine on Ca2+-dependent K+ channels. Even at doses up to 10 μM, almitrine has no effect on whole-cell voltage-dependent K+, Ca2+, or Na+ currents in rat or rabbit cells. On the other hand, in rat chemoreceptor cells, almitrine at this dosage dramatically suppressed the Ca2+-dependent component of K+ current [1].

ln Vivo |
Amitripline operates through peripheral arterial chemoreceptors to augment carotid sinus nerve output and minute ventilation. Almitrine also has pulmonary vasculature, inducing dose-dependent constriction and dilatation. Low doses of Almitrine augment hypoxic pulmonary vasoconstriction and may improve the overall ventilation/perfusion ratio [2].

Additional Infomation |
Almitrine dimesylate is the dimethanesulfonate salt of almitrine. It has a role as a central nervous system stimulant. It contains an almitrine.
Almitrine Mesylate is the mesylate form of almitrine, a diphenylmethylpiperazine derivative and respiratory stimulant that can be used to improve oxygenation. Upon systemic administration, almitrine targets, binds to and activates the peripheral chemoreceptors located on the carotid bodies. This enhances respiration and increases arterial oxygen tension while decreasing arterial carbon dioxide tension. A respiratory stimulant that enhances respiration by acting as an agonist of peripheral chemoreceptors located on the carotid bodies. The drug increases arterial oxygen tension while decreasing arterial carbon dioxide tension in patients with chronic obstructive pulmonary disease. It may also prove useful in the treatment of nocturnal oxygen desaturation without impairing the quality of sleep. |

Solubility (In Vitro) |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (3.73 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (3.73 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

10 mM | 0.1493 mL | 0.7465 mL | 1.4931 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
