Dispensing of minitablets - Has the problem been resolved?

Recently, minitablets have been given extensive coverage in literature, as they are perfectly matched to the current therapy individualization trend. Within this scope, special attention is paid to minitablets that enable convenient drug intake for patients with swallowing problem. However, the packaging system, dispensing the necessary amount of drug units and safe administration still remain unsolved problems or are partially overlooked. Although there are many different approaches towards dosing tablets, only a few seem to be tailored to particularly small tablets. Moreover, none of these approaches meets all the user's expectations. This paper comprehensively elaborates and critically discusses the available dosing options like sachets, blisters, home electronic dispensing systems and minitablets manual dispensers. Additional tests have been also conducted to simulate the handling and dosing procedure with 2 mm diameter placebo minitablets. Despite many advantageous inventions, it has been revealed that further efforts are necessary to identify the optimal design that would allow to eliminate the shaking procedure, adjust cavities diameter or provide better protection against humidity. Nevertheless, the current trend may lead to individual therapy becoming more convenient, safe and reliable, especially in pediatric and geriatric patients.
