## Abstract

ABSTRACT/SUMMARY
Dose dumping, which is defined as ‘‘unintended, rapid drug release in a short period of time of the entire amount
or a significant fraction of the drug contained in a modified release dosage form’’ can have dangerous effects.
Currently, the FDA recommends to assess the risk of alcohol-induced dose dumping for opioid and non-opioid
drugs with a narrow therapeutic index, such as metoprolol succinate (β-blocker) and venlafaxine HCl
(antidepressant). Especially, prolonged-release formulations, which offer a reduced dosing frequency and a
prolonged therapeutic effect due to higher drug amounts, are of specific interest. If the opioid drugs-containing
dosage form is consumed with ethanol, the drug release can increase immediately, resulting in an overdose and
leading to respiratory depression followed by hypoxia and even death. Regarding non-opioid drugs, alcohol might
enhance sedation (through synergistic interactions), decrease in motoric skills and may lead to orthostatic
hypotension. However, not many research studies have been reported in the literature on alcohol-induced dose
dumping. It is important to understand effect of formulation, excipients and manufacturing method on the
vulnerability of modified released formulation to dose dumping by alcohol. Ideally, the modified release
formulation should be rugged, not vulnerable to alcohol-induced dose dumping for safety and efficacy points of
view. The objectives of this project are to mechanistically and systemically understand the effect of formulation
composition, formulation design, excipients properties, manufacturing methods and processes parameters on
alcohol-induced dose dumping. The team has extensive experience on alcohol-induced dose dumping, abuse
deterrent, and meth-deterrent formulations development, evaluation of formulation vulnerability to abuse and
dose dumping, understanding and development of metrics for comparison and evaluation of abuse deterrence
and alcohol-induced dose dumping properties, and classification of formulation vulnerability and ruggedness to
abuse and dose dumping at DPQR (Division of product Quality and Research at FDA). Following are the specific
aims of the proposal: Aim I: Mechanistically understand the effect of drug-related factors on alcohol-induced
dose dumping from extended release formulations; Aim II: Mechanistically understand the effect of formulation-
related (composition and design) factors on alcohol-induced dose dumping from extended release formulations;
and Aim III: Mechanistically understand the effect of manufacturing method and process-related factors on
alcohol-induced dose dumping from extended release formulations. This proposal focusses on fundamental
understanding of excipients properties, manufacturing methods and process parameters that may contribute
vulnerability to dose dumping due to alcohol. This basic understanding about the alcohol-induced dose dumping
will help the agency in framing the policy regarding vulne...
