Objective: To assess the effect of concomitant food intake on the relative bioavailability of ospemifene and its main metabolite, 4-hydroxyospemifene, after single oral dosing. Methods: This was an open-label, randomized, balanced, two-treatment (fed vs. fasted), two-period, two-sequence cross-over study in 24 healthy male subjects. Single 60-mg doses of ospemifene were administered without food or with a high-fat, high-energy breakfast (860 kcal). In an extension study, a single 60-mg dose of ospemifene was given to 12 subjects with a low-fat, light breakfast (300 kcal). Addnl. information was acquired by determining tablet dissolution profiles in media which reflected fasted and fed intestinal conditions. Results: The AUC0-72h and Cmax of ospemifene were 2.8- and 3.6-fold higher after a high-fat breakfast and 1.9- and 2.3-fold higher after a low-fat breakfast when compared with an overnight fast. The variability in both primary pharmacokinetic parameters was considerably reduced (by up to 50%) with a meal, indicating more consistent absorption of ospemifene with concomitant food intake. Dissolution in conditions simulating fed intestinal fluid (high bile acid concentration) was increased 3-fold compared with dissolution in simulated fasted intestinal fluid. Conclusions: Food markedly enhanced the extent and predictability of ospemifene absorption. The increase in bioavailability was not linearly related with the fat content of the meal. In vitro dissolution results were consistent with these clin. observations. Administration with food enhances and standardizes the oral bioavailability of ospemifene. Thus, it is recommended that ospemifene tablets should be taken with food. In the experiment, the researchers used many compounds, for example, (Z)-2-(4-(4-Chloro-1,2-diphenylbut-1-en-1-yl)phenoxy)ethan-1-ol (cas: 128607-22-7HPLC of Formula: 128607-22-7).
(Z)-2-(4-(4-Chloro-1,2-diphenylbut-1-en-1-yl)phenoxy)ethan-1-ol (cas: 128607-22-7) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.HPLC of Formula: 128607-22-7
