Abstract
Over th past decade, beta-blockers have shown their promise in the therapy of skin hemangiomas. Infantile hemangiomas are the most common soft tissue tumors occurring in 4-10% of children under the age of 1 year. Various methods are used to treat the disease: laser therapy, surgical exci-sion, cryodestruction, sclerosing, as well as conservative treatment with systemic glucocorticosteroids and beta-blockers administered enterally, topi-cally, and externally. Pharmacotherapy with the use of application dosage forms of beta-receptor antagonists is considered to be the most effective and safe method. This approach to treatment has several advantages over the oral method of administration: first, the convenience and painlessness of use, and secondly, the local effect on the pathological process, hence reducing the risk of systemic side effects (bradycardia, hypotension, bron-chospasm, insomnia). All these advantages emphasize the relevance of the development of soft dosage forms of beta-blockers. The patent RU 2471500 C2 “Use of beta-blocker for preparing drug for treating hemangiomas” proposes atenolol, betaxolol, bisoprolol, carvediol, metoprolol, nebivolol, propranolol and sotalol as antiangiogenic agents. The creation of soft dosage forms of beta-blockers with domestic transcutaneous enhancer Tizol gel is a solution to the problem of targeted delivery of active substances to the lesion site. For the development of new drugs, one of the most fundamen-tal areas of pharmaceutical science, pharmaceutical analysis, is of fundamental importance. The main objectives of pharmaceutical analysis are to determine the qualitative and quantitative characteristics of medicines. This article provides a review of the main methods for the analysis of beta-blockers used for the effective quality control of medicines, as well as methods for identifying, quantifying, and biopharmaceutically analyzing new ointments based on Tizol gel.
