A novel mucoadhesive buccal tablet containing flurbiprofen (FLB) and lidocaine HCl (LID) was prepared to relieve dental pain. Tablet formulations (F1-F9) were prepared using variable quantities of mucoadhesive agents, hydroxypropyl methyl cellulose (HPMC) and sodium alginate (SA). The formulations were evaluated for their physicochemical properties, mucoadhesive strength and mucoadhesion time, ...

Poorly water-soluble drugs, such as phenylephrine, offer challenging problems for buccal drug delivery. In order to overcome these problems, particle size reduction (to the nanometer range) and cyclodextrin complexation were investigated for permeability enhancement. The apparent solubility in water and the buccal permeation of the original phenylephrine coarse powder, a phenylephrine-cyclodext...

OBJECTIVE: This study was conducted to characterize the pharmacokinetics, including extent of accumulation, and safety and tolerability of fentanyl following multiple doses of fentanyl buccal tablet (FBT) in healthy Japanese volunteers. METHODS: Healthy Japanese adults received 10 successive doses of open-label FBT 400 microg at 6-hour intervals. Naltrexone was given to minimize the opioid effe...

Breakthrough pain, a transitory severe pain with the background of otherwise controlled persistent pain has a prevalence between 52% and 67% in outpatients with cancer. Medications for such sudden-onset pain require non-invasive delivery of a potent and short-acting opioid for rapid pain relief. Although oral transmucosal delivery of fentanyl citrate (OTFC) has been shown to provide better pain...

The objective of the paper is to study the effect of a permeation enhancer, sodium taurocholate on permeation of Ondansetron HCl from bioadhesive buccal tablet formulation by performing ex-vivo permeation experiments using porcine buccal mucosa. Optimized formulation has selected based on in-vitro drug release studies of bilayered bioadhesive buccal tablets. To the optimized formulation, 10mM s...

OBJECTIVE: This study was conducted to assess the dose proportionality, safety, and tolerability of fentanyl buccal tablet (FBT) in Japanese volunteers. METHODS: Healthy, opioid-naive Japanese adults received single-dose FBT 100, 200, 400, and 800 microg in a randomized, open-label, crossover fashion. Naltrexone was given to minimize the opioid effects of fentanyl. Peak serum fentanyl concentra...

OBJECTIVE To evaluate the time of onset, overall efficacy, and safety of fentanyl buccal tablet (FBT) for noncancer-related breakthrough pain (BTP) in opioid-tolerant adults over 12 weeks. DESIGN A novel 12-week study that mimicked clinical practice with dose titration to effective dose, open-label treatment, and three randomized, double-blind, placebo-controlled, multiple-crossover periods a...
