Each 5ml oral suspension of Drutemal®- Plus (after reconstitution) contains Artemether 20mg + Lumefantrine 120mg.

Each tablet of Drutemal®- Plus contains Artemether 40mg + Lumefantrine 240mg

Each tablet of Drutemal®- Plus (DS) contains Artemether 80mg + Lumefantrine 480mg.


Artemether is a semisynthetic derivative of artemisinin while lumefantrine is a chlorobenzylidine derivative. The site of antiparasitic action of both components is the food vacuole of malaria parasite, where they interfere with the conversion of haem, a toxic intermediate produced during haemoglobin breakdown, to the nontoxic haemozin. Lumefantrine is thought to interfere with the polymerisation process, while artemether generates reactive metabolites as a result of the interaction between its peroxide bridge and haem iron. Both artemether and lumefantrine have a secondary action involving inhibition of nucleic acid and protein synthesis within the malaria parasite.


Peak plasma concentrations have been achieved in about 3 hours after oral administration of artemether. The bioavailability of lumefantrine after oral administration is variable; absorption begins after a lag-time of up to 2 hours and bioavailability is substantially increased by administration with food, particularly meals high in fat. Peak plasma concentrations occur after about 6 to 8 hours. Artemether and lumefantrine are both highly bound to human serum protein in vitro (95.4% and 99.7% respectively). Dihydroartemisinin an active metabolite of artemether is also bound to human serum proteins (47%-76%).

Lumefantrine is N-debutylated, mainly by CYP3A4, in human liver microsomes.

Artemether and dihydroartemsinin are rapidly cleared from plasma with an elimination half life of about 2 hours. Lumefantrine is eliminated very slowly with a terminal half-life of 2-3 days in healthy volunteers and 4-6 days in patients with falciparum malaria.


Drutemal®- Plus is indicated for the treatment of uncomplicated Plasmodium falciparum malaria including severe malaria caused by multiple drug resistant Strains of P. falciparum.


The first dose of the Drutemal®- Plus Suspension (after reconstitution) and tablets should be given at the time of initial diagnosis, then should be followed by five further doses at 8,24,36,48 and 60 hours thereafter.

*          Patients with known hypersensitivity to the active substances or to any of the excipients.

*          Antiarrhythmics of classes lA and lll.

*          Certain antibiotics including some agents of the following classes: macrolides, fluoroquinolones.

*          Patients with a history of symptomatic cardiac arythmias or with clinically relevant bradycardia or with congestive cardiac failure accompanied by reduced left ventricle ejection fraction.

*          Patients with disturbances of electrolyte balance e.g hypokalemia or hypomagnesemia.


Adverse effects associated with lumefantrine in combination with artemether commonly include headache, dizziness, sleep disturbance, palpitations, gastrointestinal disturbances, anorexia, pruritus, rash, cough, arthralgia, myalgia and fatigue.


In patients previously treated with halofantrine,Drutemal®- Plus should not be administered earlier than one month after the last halofantrine dose.

                    KEEP OUT OF THE REACH OF CHILDREN!


ln cases of suspected overdosage symptomatic and supportive therapy should be given as appropriate, which should include ECG and blood potassium monitoring.


Store in a cool, dry place below 30oC. Protect from light.
