Mechanism of Action |
The mechanism of action of diethylcarbamazine is thought to involve sensitizing the microfilariae to phagocytosis. One study showed that diethylcarbamazine's activity against Brugia malayi microfilariae is dependent on inducible nitric-oxide synthase and the cyclooxygenase pathway. It confirmed the important role of the arachidonic acid metabolic pathway in diethylcarbamazine's mechanism of action in vivo and showes that in addition to its effects on the 5-lipoxygenase pathway, it targets the cyclooxygenase pathway and COX-1. |

Feasible Synthetic Routes
Q1: How does DEC affect calcium signaling in Brugia malayi muscles?
A1: DEC interacts with the transient receptor potential channel, C classification (TRPC) ortholog receptor TRP-2 in Brugia malayi muscles. This interaction promotes calcium ion (Ca2+) entry into the muscle cells, leading to muscle contraction and potentially contributing to paralysis. []
Q2: Does DEC have any synergistic effects with other anthelmintics?
A2: Yes, DEC demonstrates synergistic effects with emodepside, an anthelmintic drug. Emodepside is thought to target Slopoke (SLO-1) Ca2+-activated potassium (K+) channels. When combined with DEC, emodepside potentiates the DEC-induced Ca2+ signal in Brugia malayi muscles, leading to enhanced inhibition of motility. []
Q3: What is the molecular formula and weight of diethylcarbamazine?
A3: Diethylcarbamazine has the molecular formula C10H21N3O and a molecular weight of 199.29 g/mol.
Q4: Does the packaging material influence the stability of DEC tablets?
A4: Yes, packaging plays a crucial role in maintaining DEC stability. A study indicated that aluminum strips with polyethylene lining are the most appropriate packaging material to ensure the stability of DEC 50 mg tablets throughout their shelf life. []
Q5: How is DEC absorbed and distributed in the body?
A5: DEC is rapidly absorbed following oral administration. [] It is then widely distributed throughout the body, including saliva. Studies have shown a strong correlation between DEC concentrations in plasma and saliva, suggesting that saliva concentrations could be used to monitor drug therapy. []
Q6: How is DEC eliminated from the body?
A6: DEC is primarily metabolized in the liver and excreted in the urine. Activated charcoal has been shown to reduce the absorption and urinary excretion of DEC by adsorbing it in the gastrointestinal tract. []
Q7: What is the efficacy of combination therapy with DEC?
A7: Combination therapies involving DEC often demonstrate superior efficacy compared to single-drug treatments. For instance, a combination of DEC and albendazole was found to be more effective at clearing Brugia malayi microfilariae than either drug alone. [] Similarly, annual mass treatment with DEC plus ivermectin resulted in a greater reduction in microfilariae-positive infections compared to DEC alone in a study conducted in Papua New Guinea. []
Q8: Is there evidence of resistance to DEC in filarial parasites?
A8: While widespread resistance to DEC has not been widely reported, the potential for its development exists. Continuous monitoring for resistance is crucial to ensure the long-term effectiveness of DEC-based treatment strategies.
Q9: What are some common adverse reactions associated with DEC treatment?
A9: DEC treatment can cause adverse reactions, particularly in individuals infected with filarial parasites. These reactions, often termed Mazzotti reactions, can manifest as fever, headache, dizziness, skin reactions, and gastrointestinal complications. [, , , , ] The severity of these reactions can vary depending on the filarial species involved, with infections of Onchocerca volvulus often associated with more severe reactions. []
Q10: Can DEC administration lead to changes in blood parameters?
A10: Yes, DEC administration has been associated with a profound decrease in circulating eosinophils, reaching their lowest levels just before or during the onset of clinical and physiological changes associated with the Mazzotti reaction. []
Q11: Are there any novel drug delivery systems being explored for DEC?
A11: Researchers are exploring the development of orodispersible tablets of DEC to enhance patient compliance, particularly among pediatric and geriatric populations who may have difficulty swallowing conventional tablets. [, ]
Q12: What analytical techniques are commonly employed for the quantification of DEC?
A12: Several analytical methods are utilized for quantifying DEC, including spectrophotometry [, ] and high-performance liquid chromatography (HPLC). [, , ] These methods are essential for quality control and assurance during drug development, manufacturing, and distribution.
Q13: Have analytical methods for DEC been validated?
A13: Yes, validated RP-HPLC methods have been developed for the simultaneous estimation of DEC with other drugs like cetirizine hydrochloride and chlorpheniramine maleate in pharmaceutical formulations. These methods demonstrate good accuracy, precision, and linearity, making them suitable for routine analysis. [, ]
Q14: When was DEC first discovered as an antifilarial agent?
A14: DEC was first identified as an effective antifilarial agent in 1947. [] Its introduction marked a significant milestone in the fight against filariasis, offering a valuable tool for controlling these debilitating parasitic infections.
