KESERVANI, Raj Kumar  and  GAUTAM, Surya Prakash. Actividad relajante del músculo esquelético de diferentes formulaciones de niosomas span 60. Ars Pharm [online]. 2022, vol.63, n.1, pp.32-44.  Epub Mar 21, 2022. ISSN 2340-9894.


Spasticity is a disease of motor neurons that manifests as accelerated muscle tone and stiffness. The niosomes can be formulated with the aid of proper adjustment of process parameters to enhance baclofen entrapment and sustaining the drug release.


The main purpose of this study is to compare different formulations of span 60 niosomes containing baclofen for skeletal muscle relaxant activity on mice (Swiss albino mice) by rota rod method.


The particle size of formulated niosomes was in the range of 3.62±0.54-4.08±0.64 µm and these were smooth, circular fit and generally small multilamellar. Entrapment efficiency of optimized formulation was 88.44±0.28 %. The most extreme % cumulative drug release was 87.88±8.66% after 10 h. The formulation stored at 4±2 °C temperature shows better stability (96.65±0.45) contrasted with raised temperature. Swiss albino mice were utilized for in vivo study and displayed improved muscle relaxant action as far as no. of tumbles from rota rod apparatus (p value =0.001) are concerned.


Nonetheless, diazepam treated mice were observed to have higher muscle relaxation than any dose of formulation tested. The formulation F9 shows better skeletal muscle relaxant activity as compared to F6, F7, F8 and F10 on mice (Swiss albino mice) by the rota rod technique.

Keywords : Niosomes; baclofen; diazepam; Swiss albino mice; skeletal muscle relaxant.
