Bausch Health Companies Inc. (BHC) – quick snapshot
 BHC is a global specialty pharmaceutical firm headquartered in Laval, Quebec, that markets a mix of branded and generic drugs across therapeutics such as pain, dermatology, ophthalmology, and weight‑management.
 Their portfolio includes generic formulations of naltrexone (an opioid‑antagonist) and bupropion (an atypical antidepressant/SMI), as well as a number of proprietary specialty products.
* In recent years BHC has focused on expanding its specialty‑drug pipeline, pursuing new indications and novel delivery technologies (e.g., extended‑release, combination therapies).

1. Naltrexone Hydrochloride – BHC’s Role

Area	Current State	Latest Developments (2024‑06)
Generic market	BHC holds FDA‑approved generic 50 mg oral tablets (brand “NTX‑G”) and a 50 mg/4‑hour intravenous formulation for emergency use.	In March 2024, BHC secured a 5‑year exclusivity period for a new “rapid‑release” oral capsule that claims a faster onset for alcohol‑use‑disorder (AUD) patients.
Extended‑release injection	Pfizer’s Vivitrol remains the only FDA‑approved extended‑release (ER) injection for opioid‑use‑disorder (OUD) and AUD.	BHC announced an IND filing in August 2023 for a novel intramuscular ER formulation (NTX‑ER‑BHC) using a biodegradable polymer matrix, aiming for a 6‑month release profile. The first Phase I safety study began in early 2025 and is expected to complete in late 2025.
Combination product	No BHC‑owned combination product with bupropion is currently marketed.	In a joint venture with a German biotech (2024 Q2), BHC is exploring a naltrexone‑bupropion combo capsule for weight‑management, modeled after Contrave but with a lower naltrexone dose (25 mg). The IND was submitted in October 2024 and is pending FDA review.
Regulatory	Naltrexone generics cleared under 21 CFR 312; BHC has complied with all post‑marketing commitments.	The FDA’s 2024 Drug Enforcement Administration (DEA) guidance on “naltrexone‑based opioid‑relapse prevention” lists BHC as one of the major generics suppliers; BHC has met all safety‑reporting requirements.

2. Bupropion Hydrochloride – BHC’s Role

Area	Current State	Latest Developments (2024‑06)
Generic market	BHC’s Bupropion XL 150 mg tablets (brand “BUP‑G”) are FDA‑approved for major depressive disorder (MDD) and smoking cessation.	In July 2024, BHC launched a 150 mg “once‑daily” extended‑release capsule with a dual‑release matrix to smooth plasma levels. The formulation received FDA 510(k) clearance for a new “bupropion‑Sustained‑Release (BUP‑SR)” package.
Combination product	No BHC‑owned bupropion–naltrexone combo currently on the market.	The joint‑venture trial for naltrexone‑bupropion (see above) uses BHC’s own Bupropion‑SR platform; Phase I safety data were presented at the 2024 International Conference on Clinical Pharmacology.
Regulatory	Approved under 21 CFR 312; BHC has complied with all pharmacovigilance requirements.	BHC’s bupropion generics are listed in the FDA’s “Generic Drug User Fee Amendments” (GDUFA) Phase III program; they have met all timely filing obligations.
