The objective of this study is to evaluate the relative bioavailability, and the rate and extent of absorption of bromocriptine in male and female children and adolescent Type 2 Diabetes Mellitus patients, aged 10 to less than 18, under fed conditions. It is undetermined if the pharmacokinetic profile of bromocriptine-QR in type 2 diabetes children aged 10- to less than 18 years differs appreciably from that in healthy adults. Bromocriptine is extensively metabolized by the liver (namely CYP3A4). Studies in children have demonstrated little difference in clearance among children over 10 years of age compared to adults (Blanco et al, 2000). However, differences in blood volumes or other factors may impart differences that could affect the pharmacokinetic properties of bromocriptine-QR. Therefore, this study will assess the pharmacokinetics in children aged 10-to less than 18 years who have type 2 diabetes. After describing the profile of bromocriptine-quick release in this patient population, a follow on study will be conducted to evaluate its safety and efficacy in treating children and adolescents who have type 2 diabetes. The pharmacokinetic profile of bromocriptine will be determined following the administration of a single, weight-adjusted dose of CYCLOSET (bromocriptine mesylate) tablets. The study will be a single period, bioavailability study in 30 patients. The study duration will be 3 days.

Corneal epithelial disruption, commonly termed "corneal staining" has been frequently associated with contact lens wear. Previous research has demonstrated higher levels of observed corneal staining when certain combinations of contact lenses and lens care products are used, particularly under daily wear regimens. B+L lenses made from Balafilcon (PureVision) have been associated with the highest rates of observed staining. Additionally, polyhexamethylene biguanide (PHMB) based lens care products, specifically B+L ReNu MultiPlus have been implicated in higher rates of staining. In general, many lenses constructed from newer, silicone hydrogel (SiHy) materials appear more susceptible to increased rates and amounts of corneal staining. Although the clinical significance of staining is debated, most clinicians agree that less staining is preferable to greater amounts of staining. Advances in understanding as well as the specifics of lens care product formulation ideally will have resulted in design of newer products that minimize corneal staining and maximize product performance. This study will examine rates of corneal staining using B+L's recently introduced lens care product: BioTrue with the B+L PureVision lens which has previously been associated with the highest levels of staining.
