CLINICAL TRIALS PROFILE FOR NALOXONE HYDROCHLORIDE AND PENTAZOCINE HYDROCHLORIDE

All Clinical Trials for NALOXONE HYDROCHLORIDE AND PENTAZOCINE HYDROCHLORIDE

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00125931 ↗	Effects of Pentazocine on Manic Symptoms	Completed	Stanley Medical Research Institute	Phase 2	2005-09-01	The opiate neurotransmitter system is thought to be involved in many abnormal mood states. Some researchers have suggested that changes in this system may trigger the switch to/from manic and depressive states in bipolar disorder. One problem with most of the currently available opiate medications is that they can produce addiction/dependence. A particular kind of opiate medication known as kappa-opiates may be able to produce changes in this system with much less risk of addiction. This study looks at Talwin (a combination of pentazocine and naloxone), a medication which affects the kappa and mu opiate systems. The study will examine whether two doses of Talwin affect manic symptoms in people who have been admitted to the hospital. This study will give more information about the involvement of the opiate system in bipolar disorder, and give important information for use in developing new treatments.

FAQs

1. What is the primary therapeutic rationale behind combining Naloxone with Pentazocine?
The combination aims to address both opioid overdose reversal (via Naloxone) and analgesic management (via Pentazocine), potentially offering a dual-action therapy. However, safety concerns necessitate rigorous clinical validation.

2. Are there approved drugs currently on the market that combine Naloxone and Pentazocine?
No, as of early 2023, no regulatory approvals have been granted for fixed-dose combination formulations of Naloxone with Pentazocine. Clinical trials are ongoing to evaluate this potential.

3. What are potential safety issues with the Naloxone-Pentazocine combination?
Pentazocine's psychotropic effects and its known abuse potential pose safety risks, which need to be mitigated through formulation design, dosing strategies, and thorough clinical testing.

4. How does the regulatory landscape impact the development of this combination?
Regulatory agencies require comprehensive safety and efficacy data, especially for combination drugs with abuse potential. Challenges include demonstrating abuse deterrence and addressing safety concerns in overdose scenarios.

5. What are the key drivers for future market growth?
The primary drivers include increasing opioid overdose rates, demand for safer and more effective overdose reversal agents, regulatory momentum favoring abuse-deterrent therapies, and innovations in drug delivery technologies.
