The gastroesophageal reflux and/or peptic ulcer diseases are clinical conditions that occur usually accompanied of symptomatic pain. Lansoprazole, a proton pump inhibitor class drug is widely used in clinical practice for treatment of these diseases. However, its efficacy can be improved by combining with spasmolytic and/or visceral analgesic such as hyoscine butylbromide. Since hyoscine butylbromide is barely absorbed and exerts some local effects at gastrointestinal tract which may modify the absorption of lansoprazole, it is important to establish if there is a pharmacokinetic interaction after the oral concomitant administration of both drugs. For this objective, twenty-five subjects received under a crossover design an oral administration of lansoprazole (15 mg) plus placebo or a fixed-dose combination with hyoscine butiylbromide (15 mg + 10 mg, respectively). Plasma samples were obtained at different times during 10 hours. Lansoprazole plasma concentrations were determined by a high performance liquid chromatography method coupled to tandem mass spectrometry. Fixed-dose combination was well tolerated. Lansoprazole pharmacokinetic parameters were: Cmax 621.81 ± 212.79 and 450.38 ± 192.14 ng/mL;AUC0-t 1941.36 ± 845.57 and 1454.66 ± 757.28 ng·h/mL;tmax 2.83 ± 0.99 and 3.40 ± 1.82h;t1/2 1.35 ± 0.39 and 1.45 ± 0.51 h, for alone and combined fixed-dose formulation, respectively. Pharmacokinetic parameters were compared by analysis of variance and ratios of AUC0-t, Cmax and 90% confidence intervals obtained. Since confidence intervals exceed the 80% - 125% limits for these parameters, we conclude that there is a significantly pharmacokinetic interaction of lansoprazole when it is administered concomitantly with hyoscine butylbromide.

Mirodenafil is a 5-phosphodiesterase inhibitor that is currently marketed in Korea for the treatment of erectile dysfunction;however, no information in other populations is available. It has been described that Mirodenafil is metabolized by CYP3A4, a metabolic pathway in which interethnic differences have been reported. The purpose of this study was to characterize the oral pharmacokinetics of Mirodenafil in Mexicans. Seventeen male healthy volunteers were enrolled in this study. After an overnight fast, volunteers received an oral 100 mg dose and blood samples were collected at selected times during 24 h. Plasma was stored frozen and analyzed by an HPLC method. Pharmacokinetic parameters obtained were: Cmax 331.129 ± 32.689 ng/mL, tmax 1.574 ± 0.293 h, AUC24h 883.293 ± 104.088 ng·h/mL, AUC￥ 976.477 ± 108.812 ng·h/mL and t1/2 1.807 ± 0.171 h. Parameter values observed in this study are similar to those reported in Koreans. Since efficacy and safety studies of Mirodenafil have been conducted in Koreans, it is expected that dosage regime to employ in Mexicans should be similar to the approved for Korean population.

In the present work, the synthesis of micro- and nano-sized spheres of metallic bismuth by microwave-assisted solvothermal method is reported. The synthesis method was carried out at different power levels and at a unique frequency of microwave irradiation. The sphere sizes were controlled by the microwave power level and the concentration of dissolved precursor. Structural and morphological characterization was performed by SEM, HRTEM, EELS and XRD. The results demonstrated that rhombohedral zero valent Bi spheres were synthesized after microwave radiation at 600 and 1200 W. However, if the power level is decreased to 120 W, a monoclinic phase of Bi203 is obtained with a flake-like morphology. In comparison with a conventional hydrothermal process, the microwave-assisted solvothermal approach provides many advantages such as shorter reaction time, optimum manipulation of morphologies and provides a specific chemical phase and avoids the mixture of structural phases and morphologies which is essential for further applications such as drug delivery or functionalization with organic materials, thanks to its biocompatibility.
