conventional tablets cannot be swallowed with out water. However, water or any other fluid is needed, by the patients, in most of the cases to swallow the capsule or tablet. The difficulty in swallowing, more commonly termed as dysphagia, is apparent in patients of all age groups, especially the pediatrics and geriatrics. The result is a high incidence of non compliance and ineffective therapy. In case of patients who are mentally ill, uncooperative, nauseated patients and those with acute episodes of coughing or asthma the time of response should be very rapid which indicates that the drug should be absorbed into the systemic circulation as early as possible.
