Example 1: In Vitro Assay of Mebeverine as sEH Inhibitor
(54) The inhibitory potential of mebeverine was observed in vitro using a sEH activity assay. 5 μl of PHOME (substrate) was added at different concentrations (10.sup.−12 to 10.sup.−7 nM) of captopril (does not inhibit sEH), Mebeverine and AUDA (known sEH inhibitor). Hydrolysis of PHOME by sEH results in the release of cyanohydrins that further decomposes to cyanide ion and 6-methoxy-2-naphthaldehyde (highly fluorescent). The fluorescence was analyzed at an excitation and emission wavelength of 330 nm and 465 nm respectively. It was observed that the enzyme activity of sEH decreased with the increase in concentrations of both the mebeverine and AUDA This shows that mebeverine is a potent inhibitor of sEH enzyme and it inhibits the activity of the enzyme in a dose-dependent manner (10.sup.−12 to 10.sup.−7 nM). Captopril showed 100% sEH activity. Interestingly, the inhibitory activity of mebeverine was found comparable to the known standard inhibitor AUDA. Mebeverine exhibited IC.sub.50 of 3.9 followed by captopril with 693.0 that were comparable to the standard AUDA with IC.sub.50 of 3.5. The results are tabulated below and have been plotted in

Example 2: Ex-Vivo Antihypertensive Studies on Isolated Rat Aortic Strip
(56) Aortic rings were suspended in organ baths containing a modified Krebs buffer and bubbled with a mixture of 95% O.sub.2/5% CO.sub.2. Rings were connected to an isometric force transducer, resting tension was set to 5 g and constricted with 80 mmol KCl. The relaxation of these pre-constricted aortic trips at different concentrations of mebeverine (10.sup.−9-10.sup.−4 nM) are tabulated in Table 2 and plotted in

(58) It was observed that mebeverine successfully increased the percentage relaxation in the rings in a dose dependent manner (10.sup.−9 nM to 10.sup.−4 nM). The maximal relaxant effect for Mebeverine was 79.3±0.01% at 10.sup.−4 nM.

Example 4: Effect of Mebeverine on Hyperlipidemia
Example 4A: Effect on Triton WR-1339 Induced Hyperlipidemia
(70) Wistar albino male rats were divided into four experimental groups (I, II, III and IV). Groups II-IV were treated with intraperitoneal injection of Triton WR-1339 (200 mg/kg in 2% gum acacia) in 12 h fasted rats to induce hyperlipidemia. Group III and IV were orally administered with Mebeverine twice daily for 3 days at 10 mg/kg and 20 mg/kg. After 48 h, induction of hyperlipidemia blood serum was investigated for total cholesterol and triglycerides. Blood samples were collected from all experimental rats on day 6 (4 days after start of treatment), and, subsequently, serum was separated for analysis of serum lipid profile parameters and CRI/AI. Liver was excised and stored at −80° C. until biochemical parameters in hepatic tissue samples were analysed. The results are tabulated below in Table 6 and plotted in
