Health condition
Health condition(s) or problem(s) studied:
Bioavailability study conducted in healthy volunteers comparing ipratropium bromide administered with and without concurrent charcoal dosing with no health condition or problem studied.

Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, ipratropium bromide belongs to a class of medicines called synthetic ammonium antimuscainic bronchodilators. It is used for the treatment of bronchospasm associated with COPD, including bronchitis and emphysema.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the formulation of ipratropium bromide (1 x 500 mcg) on one occasion with oral charcoal administered pre-dose and at specified times up to 4 hours post dosing and on one occasion without oral charcoal with each dose separated by a one week washout period. The intervention for this trial is ipratropium bromide with charcoal.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose).
Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose.

Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored and for 24 hours after dosing.

Standard meals will be consumed at the Clinical Site with no additional food intake allowed.

Vital sign examination, assessment of well-being, alcohol breath testing, drug testing and pregnancy testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing.

Pre and post study laboratory tests will be completed to assess the healthy of participants along with HIV, Hepatitis and drugs of abuse testing.

The volunteer's randomsied to receive 50 ml of activated charcoal suspension will be given the charcoal suspension 2 minutes prior to dosing, immediately with dosing and also at 1, 2 and 4 hours post dosing.

Each dose (1 x 500 mcg) will be taken orally as 2 ml of ipratropium bromide solution in 18 ml of water. Medication will be administered via a 30 ml syringe and a mouth check will be conducted to ensure the medication has been taken as directed.

Comparator / control treatment
Single dose, crossover study design whereby each participant receives ipratropium bromide (1 x 500 mcg) with concurrent oral charcoal on one occasion and ipratropium bromide (1 x 500 mcg) on one occasion without oral charcoal with each dose separated by a one week washout period. The comparator/control for this trial is ipratropium bromide without charcoal.

Active

Outcomes
Primary outcome [1] 293346 0
To compare the bioavailability of ipratropium bromide (as summarised by Cmax and AUC) with and without concurrent oral charcoal. All plasma samples will be assayed for ipratropium bromide using one fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All formulations will be labelled as Formulation A and B. The identification of each treatment will only be known to the Managing Director and the Section Head - Trials and Regulatory Affairs.

Each participant will be identified by a 3 digit screening number and a 2 digit subject number. The screening number will be issued once the participant has given written consent to participate in the study and the two digit subject number (randomisation number) after acceptance into the study
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation list will be prepared using a computer program for a balanced two-way crossover design.
Masking / blinding
