Pharmacological Evaluation of Sedum lineare Thunb Extract: Acute Toxicity and Anticonvulsant Effects in Swiss Albino Mice

Abstract

Aim: This study aimed to assess the acute toxicity and anticonvulsant effects of the hydroalcoholic extract of Sedum lineare Thunb in Swiss albino mice. Materials and Methods: Acute toxicity was evaluated by administering a high dose (2000 mg/kg) of the hydroalcoholic extract and monitoring mortality, behavioral changes, body weight, and food/water consumption. Hematological parameters and organ histopathology were analyzed to assess systemic effects. The anticonvulsant activity was explored using pentylenetetrazole (PTZ) and picrotoxin-induced seizure models at various extract doses (100, 250, and 500 mg/kg). Results and Discussion: The acute toxicity study revealed the safety of the hydroalcoholic extract, with no observed mortality, behavioral changes, or adverse effects on body weight and food/water consumption. While hematological changes were statistically significant, their clinical relevance requires further exploration. Histopathological examination confirmed the absence of organ toxicity. In the anticonvulsant assessment, the hydroalcoholic extract exhibited a protective effect against PTZ-induced seizures, significantly delaying jerk onset at the highest dose. Although not prevent clonic convulsions entirely, it dose-dependently reduces mortality rates. In the picrotoxin model, particularly at 250 mg/kg, the extract significantly increased clonic convulsion latency and suppressed mortality, indicating a potential modulatory role against seizures. Conclusion: The hydroalcoholic extract of S. lineare Thunb demonstrated favorable acute toxicity and promising anticonvulsant effects in Swiss albino mice. The observed hematological changes warrant further investigation for clinical relevance, and additional studies, including long-term assessments and biochemical analyses, are recommended to comprehensively evaluate the extract’s safety and therapeutic potential. These findings support further exploration of S. lineare Thunb as a potential candidate for neurological disorder interventions..
