Malaria remains a significant challenge for health worldwide, especially in the tropical and sub-tropical areas where it is endemic. The treatment of the parasite responsible for malaria, namely Plasmodium falciparum, involves use of effective chemical therapies that can circumvent increasing drug resistance. The most successful therapy is based on the use of Artemisinin-based Combination Therapy (ACT), which is recommended by the World Health Organization (WHO). In combination therapy drugs, Lumefantrine USP is one of the key components of a drug.
Prism Industries Pvt. Ltd. produces APIs with the highest level of purity for compliance with the requirements of the global pharmacopeia. The study of the chemistry, action, and production of Lumefantrine USP demonstrates its importance for the manufacture of drugs.
What is Lumefantrine USP?
Lumefantrine (chemically represented as 2,7-dichloro-9-(4-chlorobenzylidene)-$\alpha$-[(dibutylamino)methyl]-9H-fluorene-4-methanol) is an artificial fluorene molecule designed to be used only for the treatment of malaria. The USP grade certification is an
Pharmacological Mechanism in Antimalarial Therapy
The key importance of Lumefantrine USP in therapy is associated with its synergistic cooperation with the fast-acting Artemisinins derivatives, primarily Artemether. On one hand, the latter provides a rapid effect of therapy at the early stages by reducing the parasitic load in the blood. On the other hand, Lumefantrine has a long-half time period of elimination.
Target Mechanism inside Plasmodium Parasites
In the erythrocytic phase of infection, P. falciparum digests its host hemoglobin in the acidic environment of the food vacuole to obtain necessary amino acids.
Heme Toxicity: As a consequence of hemoglobin digestion, toxic free heme (ferriprotoporphyrin IX) is generated that poses threat to the membranes of the parasite.
Biocrystallization Inhibition: Lumefantrine accumulates in the acidic environment of the parasite’s vacuole where it binds with toxic heme to prevent its biocrystallization into non-toxic hemozoin.
Parasite Lysis: As a result of accumulation of toxic heme-Lumefantrine complex, the membranes and metabolism of the parasite are destroyed.
Key Advantages of Lumefantrine USP in API Formulations
There are several advantages for pharmaceutical formulators by using premium-quality Lumefantrine USP.
Core Benefits for Formulators:
Synergy: Perfectly synergizes with Artemether in ACT treatment, delivering clearance above 95%.
Resistance: The dual therapy approach ensures that there is a greater genetic barrier towards multi-drug resistance in Plasmodium species.
Stability and Bioavailability: Due to its lipophilicity, the drug easily distributes across the body system with the correct formulation or when taken together with fatty foods.
Formulation development of dosage forms using Lumefantrine USP poses its own set of chemical issues owing to its hydrophobic characteristics. Lumefantrine is almost insoluble in water and dilute acids, thus particle size distribution and polymorphism become important considerations during formulation.
Physicochemical Challenges and Formulation Solutions
Prism Industries Pvt. Ltd. meets the challenges posed by the above formulation issues with optimized processing conditions:
Particle Size Enhancement: This process increases the surface area of the API and helps improve the dissolution rate in solid dosage forms.
Polymorph Stability: The proper handling of the crystallization process provides consistency in the polymorph from one batch to another, preventing random drug release during shelf-life.
Compatibility of Lipidic Excipients: Our highly pure API exhibits good stability when combined with surfactant systems and oral drug delivery formulations.
