Objective: Organophosphorus compounds (OPs) are common causes of poisonings. Atropine and oximes are pharmacological antidotes of OPs. However, because of their adverse effects and insufficient performance, several other compounds have been evaluated as adjuvant therapy. HESA-A is a herbal-marine drug that contains material from Carum carvi (Persian cumin), Penaeus latisculatus (king prawn), and Apium graveolens (celery) with anti-inflammatory and antioxidants properties, which has shown useful effects as adjuvant therapy on some diseases. We have evaluated the effect of HESA-A on 69 moderate to severe acute OPs poisoned patients (44 HESA-A treated and 25 controls) as an adjuvant drug.
Materials and Methods: Two randomized age and sex matched groups of OPs poisoned patients were treated in Medical Toxicology Center of Imam Reza hospital, Mashhad, by conventional therapy with or without HESA-A (50 mg/kg/day orally). The evaluation criteria were total administrated doses of atropine and pralidoxime, intensive care unit (ICU) admission rate, mechanical respiration need, number of hospitalization days and mortality.
Results: There were no significant differences between the morbidity and mortality rate criteria of the two groups; moreover, we did not observe significant adverse effects for HESA-A.
Conclusion: HESA-A did not reduce morbidity and mortality of OPs poisoning and did not induce any major side effect in the patients.
