Abstract


The aim of this work was the development of technology of rectal suppositories of immunomodulatory action for children and their standardization.

To obtain suppositories, a licorice root extract, chamomile and tea tree essential oils were used. Given that the introduction of ingredients in a dissolved form is preferable, we studied the possibility of using emulsion suppository bases. To evaluate the compositions, the homogeneity and colloidal stability of the suppositories obtained were studied. Estimation of homogeneity, melting temperature, decay time, average mass was carried out according to the State Pharmacopoeia. To confirm the authenticity of the active ingredients, a chromatography method was used. The quantitative determination of glycyrrhizin acid was carried out by spectrophotometric method.

Suppositories were prepared by the pouring method. The licorice root extract was added to the suppository when dissolved in the hydrophilic phase of the base. Essential oils of chamomile and tea tree were introduced when a solid fat of type A dissolved in a melt, at a temperature of (42.0±2.0) ºC. Optimum indices for the criteria of “homogeneity” and “colloidal stability” were noted for the samples of the composition: purified water, polysorbate-80, lecithin, solid fat type A. To prove the authenticity of the licorice root extract in suppositories, the chloroform-methanol-water system was optimal (26:14:3). Identification of essential oils on a gas chromatograph showed that on the chromatogram the peaks and retention times of the solution under study coincide with the peaks and retention times of the reference solutions. The conducted studies of quantitative determination of glycyrrhizin acid have shown that its content in one suppository is not less than 0.035 g in terms of glycyram.
