Lether 150mg Injection is identified as an antimalarial pharmaceutical mainly used for the cure of severe malaria provoked by Plasmodium falciparum strains. It plays an essential part in defeating strains immune to various other antimalarial drugs.

Arteether functions as a powerful antimalarial by interrupting the life cycle of the malaria parasite. Being an artemisinin derivative, it disrupts the ability of the parasite to live in red blood cells, successfully treating severe instances of falciparum malaria.

The dosage and administration of it relate to the formulation used. For Alpha/beta Arteether in adults, it is administered through intramuscular injection for three consecutive days. Child dosage is determined based on body weight Artemotil, a version of Arteether limited for use in children below 16, involves intramuscular injections following a loading dose.

Although it is effective against malaria, it may have some side effects. Possible cardiac issues include bradycardia and QT interval prolongation. Neurotoxicity has been observed in animal testing. Patients might also experience discomfort at the injection site, which can be managed by rotating injection sites.

It is contraindicated in expectant females under 16 years and those with known hypersensitivity to artemotil or sesame oil. It is not meant for the treatment of ordinary falciparum or vivax malaria. Extra care should be taken in situations of preexisting renal or liver failure, with precautions advised for patients with heart conditions and drug resistance.

If a dosage of this drug is missed, it is essential not to double the following dose. The forgotten dose should be consumed as soon as recalled, unless it is nearly time for the upcoming scheduled dose.
