Actions and Spectrum:
Actions:
In patients with COPD, almitrine is given to improve oxygenation and ventilation by acting on the pulmonary circulation. It is a respiratory stimulant and pulmonary vasoconstriction. The action of almitrine can be seen in constricting the blood vessels in the lungs, which improves the blood flow with increased efficiency, leading to better oxygenation. It also increases respiratory rate.
Spectrum:
The spectrum of activity of almitrine is used in the management of conditions such as COPD, Acute exacerbations, Respiratory drive stimulation, Pulmonary vasoconstriction and improving ventilation and oxygenation.

Contraindication/Caution:
Contraindications
Cautions
Pregnancy consideration:
No data is available regarding the administration of the drug during pregnancy.
Breastfeeding warnings:
Limited data is available regarding the excretion of drug in breast milk.
Pregnancy category:
Category A: well-controlled and satisfactory studies show no risk to the fetus in the first or later trimester.
<b>Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.
Category N: No data is available for the drug under this category.
Pharmacology:
In patients with COPD, almitrine is given to improve oxygenation and ventilation by acting on the pulmonary circulation. It is a respiratory stimulant and pulmonary vasoconstriction. The action of almitrine can be seen in constricting the blood vessels in the lungs, which improves the blood flow with increased efficiency, leading to better oxygenation. It also increases respiratory rate.
Pharmacodynamics:
In patients with COPD, almitrine is given to improve oxygenation and ventilation by acting on the pulmonary circulation. It is a respiratory stimulant and pulmonary vasoconstriction. The action of almitrine can be seen in constricting the blood vessels in the lungs, which improves the blood flow with increased efficiency, leading to better oxygenation. It also increases the respiratory rate by its action as a peripheral chemoreceptor agonist on carotid bodies.
Pharmacokinetics:
Absorption
The bioavailability is 70%
The time to achieve peak effect is 2-4 hours
Distribution
Limited data is available.
Metabolism
Metabolism of almitrine occurs in the liver. Limited data is available regarding the complete pharmacokinetics of almitrine.
Elimination and Excretion
Elimination is through hepatic metabolism and excretion through urine.
Administration:
Administration of almitrine is via oral or IV in divided doses. Depending on the patient condition and response, monitoring of the dose is recommended.
Patient information leaflet
