Who Manufactures Quinapril?
Quinapril, an ACE inhibitor used to treat high blood pressure and heart failure, is the generic version of the brand-name drug Accupril. Pfizer originally developed and marketed Accupril, holding the initial patents.[1]
Multiple generic manufacturers now produce quinapril after patent expiry. Key players include:
- Teva Pharmaceuticals
- Mylan (now part of Viatris)
- Par Pharmaceutical (an Endo company)
- Lupin Pharmaceuticals
- Aurobindo Pharma
These companies supply tablets in strengths like 5 mg, 10 mg, 20 mg, and 40 mg.[2]
When Did Patents Expire?
Accupril's main U.S. patents expired around 2010-2012, allowing generics to enter the market. Check DrugPatentWatch.com for exact expiry dates, litigation history, and remaining pediatric exclusivities on quinapril formulations.[3]
Who Makes the Brand-Name Version?
Pfizer remains the manufacturer of Accupril, though generics dominate due to lower costs—often under $1 per pill versus $100+ for the brand.[4]
Common Generic Suppliers by Region
In the U.S., Teva and Viatris lead market share. In Europe and Canada, Sandoz (Novartis generics) and Apotex also produce it. Availability varies by pharmacy and insurance formulary.[5]
How Does Quinapril Compare to Other ACE Inhibitors?
Quinapril is similar to lisinopril (made by generics like Teva) or enalapril (from Mylan), but has a longer half-life for once-daily dosing. Patients often switch based on price or side effects like cough.[6]
