Further, research revealed that the polyethylene glycol monostearate modied SLNs were also absorbed by way of GI tract and showed a prolonged impact in vivo.
The average particle size, zeta potential, and EE with the SLNs were a minimum of 250 nm, 30. 2 mV, and 70%, respectively. The optimized SLNs were prepared employing 80 mg of cetyl alcohol, 10 mg of lecithin, acetone:DCM ratio of 1:2, 30 s sonication, 3% Tween 20, and a mixing price of 800 rpm. The pharmacokinetic cdk1 inhibitor study performed in male Wistar rats following oral administration of 10 mg kg1 pentoxifylline in the form of SLNs or free drug showed that the relative bioavailability of pentoxifylline in SLNs was signicantly increased in compare to that of the pentoxifylline solution. The study indicated that SLNs could be potential carrier of pentoxifylline to improve the oral bioavailability by avoiding high rst pass effect. Praziquantel. Praziquantel loaded SLNs were prepared by ultrasound technique to enhance the oral bioavailability of praziquantel.
In another recent study, praziquantel loaded hydrogenated castor oil SLNs were prepared to increase bioavailability Cell Cycle inhibitor and prolong systemic circulation of the drug. SLNs were prepared by hot homogenization and ultrasonication method. The particle size, polydispersity index, zeta potential, encapsulation efciency, and loading capacity of the SLNs were 344. 0_15. 1 nm, 0. 31_0. 08, 16. 7_0. 5 mV, 62. 17_6. 53%, and 12. 43_1. 31%, respectively. An initial burst release followed by a sustained release was observed from in vitro drug release study of the SLNs. Pharmacokinetic study in mice following oral, subcutaneous, and intramuscular administration of the praziquantel loaded SLNs indicated increase in bioavailability of praziquantel by 14. 9, 16. 1, and 2. 6 fold, respectively.
Rifampicin, Isoniazid, and Pyrazinamide. Pandey et al. incorporated rifampicin, isoniazid, and pyrazinamide into SLNs prepared by emulsion solvent diffusion technique and evaluate their potential against experimental tuberculosis. Encapsulation efciencies for rifampicin, isoniazid, and pyrazinamide were 51 _5%, 45_4%, and 41_4%, respectively.
