Nurofen Ibuprofen Orodispersible Tablet Disintegration Study

Study Overview
=================
Brief Summary
-----------------
Disintegration time is an important quality attribute of ODTs, and the evaluation of disintegration time is positioned as a key step in formulation development, manufacturing, and clinical practice. The standard recommended over-the counter dose of 200mg Nurofen ibuprofen ODT is one (200mg) to two (400mg) tablets. To reflect this, the disintegration time of both one (200mg) and two (400mg) tablets will be assessed in this study. Studies have been performed assessing in vivo ODT disintegration time and have created standardised oral conditions by giving water prior to dosing, to moisten/wet the mouth. In this study it is therefore necessary to standardise the oral conditions as much as possible, despite the interpersonal variability, to measure the time it takes for the ODT to disintegrate. For this study, 20 mL of water is swallowed prior to dosing to standardise oral conditions. Thirty-three healthy volunteers are required to be randomised into the study, to allow evaluable data to be obtained for 30 subjects. Subjects are given a light meal/snack and then fast for 2 hours 15 minutes (± 15 minutes) before dosing, in order to bring the oral cavity environment as close as possible to standard levels and to minimise variability in salivation. Directly before dosing, subjects drink (with oral cavity rinsing) 20 mL of water. Subjects are dosed according to the sequence they have been randomised and the ODT disintegration time assessed. Following the first dose, subjects complete a washout period of a minimum of 4 hours, in accordance with the recommended posology, before receiving the second dose. During this washout period, subjects are given a second light meal/snack (the same as the previous light meal/snack), timed to allow subjects to fast for 2 hours 15 minutes (± 15 minutes) before the second dose. Directly before the second dose, subjects drink (with oral cavity rinsing) 20 mL of water. Subjects then receive the alternative dose to the dose they received during the first assessment, in accordance with the randomisation sequence. Following completion of the disintegration assessments, or upon subject withdrawal, subjects are asked whether they are experiencing any symptoms or complaints. Any AEs are recorded in the CRF and followed up as necessary by the Investigator. Subjects then leave the clinic.Subjects are contacted by the Investigator (or designee) from 24 to up to 48 hours to ensure any AEs are captured.

A current or recent history (within one year of the study) of alcohol abuse or significant abuse/misuse of any legal or illegal drugs, substances and solvents Those with a positive screen/test for drugs of abuse and/or alcohol Those who consume more than 14 units of alcohol per week, and where this consumption is spread over less than 3 days, or those who regularly (weekly) consumed excessive amounts of alcohol (>8 units for men and >6 units for women in one consumption, excessive amounts as defined by the UK National Office of Statistics) Those who had consumed alcohol within the 24 hours before enrolment onto the study. Those who had regularly consumed excessive quantities of caffeine (>6 cups of tea, coffee or cola per day), according to the Investigator's judgment. Those who had consumed caffeine-containing food and drinks within the 24 hours before enrolment onto the study. Those who had performed strenuous exercise within the 24 hours before enrolment onto the study. Those who currently or have recently (within last 6 months) use/d tobacco or nicotine containing products. Those who have used any herbal/vitamin or fish oil supplement in the 7 days prior to enrolment Those who have used any OTC or prescription medications (except hormonal contraceptives) in the 7 days prior to enrolment Those who have used ibuprofen with concomitant aspirin or other NSAIDs including cyclooxygenase-2 selective inhibitors and any drugs that should be used with caution, in combination with ibuprofen as per the SmPC, in the 7 days prior to enrolment (or longer if stated within the SmPC) Those previously randomised into this study. Those who are an employee at the study site. Those who are a partner or first-degree relative of the Investigator or other employees. Those who have participated in any taste testing study within 3 days of the screening visit. Those who have participated in a clinical trial involving consumption of an investigational medicinal product within 3 months of dosing or a study with a marketed compound in the last month before dosing. Those unable in the opinion of the Investigator to comply fully with the study requirements. Women who are pregnant or breast feeding
