Research and development costs for a single new pharmaceutical that is introduced to the market are estimated to cost between $1 billion and $2 billion. Due to the high cost of development and the need to quickly access various technologies, it is more cost-effective (clinically and financially) to enhance current pharmaceuticals for potency, selectivity, drug metabolism, and dosing convenience before they reach the market. Orally dissolving tablets have been developed as a result. Pharmaceutical companies have created oral disintegrating tablets that dissolve or disintegrate in the mouth within a few seconds of being placed there in order to maximize the safety and efficacy of the medicine molecule. Because patients with weak physiological (patients with mental illnesses) and physical capacities can easily administer it to geriatrics, children, and patients with these conditions (patients suffering from dysphagia), as well as traveling patients who may not have easy access to water and where swallowing conventional solid oral-dosage forms presents difficulties, it has grown in popularity among a wide population. These tablets can be prepared in many ways like direct compression, freeze drying, sublimation, molding, and spray drying by using single or combinations of superdisintegrants or subliming agents.
