Actions and SpectrumÂ
DL-Methylephedrine stimulates both alpha- and beta-adrenergic receptors. Activation of these receptors leads to effects such as increased heart rate, increased blood pressure, and bronchodilation.Â
DL-Methylephedrine has vasoconstrictive properties, which means it can constrict blood vessels. This action can reduce nasal congestion by decreasing blood flow to the nasal mucosa.

Caution:Â
Pregnancy consideration:Â
Pregnancy category: N/AÂ
Lactation: Excretion into human milk is unknown Â
Pregnancy Categories:        Â
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.Â
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women. Â
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.Â
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.Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.Â
Category N: There is no data available for the drug under this category.Â
Pharmacology Â
DL-Methylephedrine has vasoconstrictive effects which causes constriction of blood vessels. This property is responsible for its use as a nasal decongestant by reducing blood flow to nasal mucosa.Â
PharmacodynamicsÂ
Stimulation of beta1-adrenergic receptors in the heart increases heart rate and contractility.Â
Stimulation of beta2-adrenergic receptors in the bronchi promotes bronchodilation.Â
PharmacokineticsÂ
Absorption  Â
DL-Methylephedrine is absorbed from the gastrointestinal tract into the bloodstream. Â
DistributionÂ
DL-Methylephedrine can distribute to various tissues.Â
MetabolismÂ
DL-Methylephedrine undergoes metabolism in the liver.Â
Elimination and excretionÂ
DL-Methylephedrine is excreted from the body through renal route.Â
AdministrationÂ
DL-Methylephedrine is available in oral capsule and liquid forms.Â
Patient information leafletÂ
Generic Name: DL-MethylephedrineÂ
Why do we use DL-Methylephedrine? Â
DL-Methylephedrine has vasoconstrictive properties, used to reduce the blood flow to the nasal mucosa. Â
DL-Methylephedrine is used as a bronchodilator, in the treatment of respiratory conditions such as asthma or bronchitis.Â
