• Concentration2023

  Bespak was founded in 1961 in King's Lynn, Norfolk specifically to manufacture the metering valve for Riker Laboratories' Medihaler — the world's first commercially available pressurized metered-dose inhaler (pMDI), launched in 1956 and a revolutionary drug delivery breakthrough for asthma patients. The Medihaler's metering valve was invented by Riker's engineers and Bespak was established as the exclusive manufacturer. Over the following 63 years, Bespak's BK357 metering valve has been qualified into the Ventolin HFA (GSK's ubiquitous blue rescue inhaler — the most recognized pharmaceutical product in the world after aspirin), Flixotide/Flovent (fluticasone), Seretide/Advair (fluticasone/salmeterol), QVAR (beclomethasone), and hundreds of other branded and generic pMDIs. The company founded to make the world's first inhaler valve still makes the majority of the world's inhaler valves — because the qualification and formulation development investment required to switch from Bespak's BK357 to any alternative is prohibitive. A 60-year-old supplier relationship, based on a 1961 manufacturing contract, persists in the supply chains of every major respiratory pharmaceutical company in the world.

• Capacity2023

  The global pMDI supply chain has an unusual structure: H&T Presspart (Lancashire, 85% of canisters), Bespak (Norfolk, ~45% of metering valves), and Koura/Orbia (Runcorn/Mexico, 75% of HFA 134a propellant) — three geographically concentrated UK/European suppliers that together provide the key components for virtually every asthma inhaler globally. Bespak's metering valve and Presspart's canister must be tested together with the specific drug formulation and Koura's propellant in an integrated pharmaceutical qualification process: the FDA and EMA require stability data for each specific drug-canister-valve-propellant combination. This creates a dense web of bilateral qualification locks between the three suppliers — switching any component requires regulatory re-qualification of the entire MDI system. The result is a supply chain resilience paradox: the components are made by highly qualified specialist suppliers with decades of pharmaceutical manufacturing expertise, but the regulatory qualification structure makes rapid substitution effectively impossible if any supplier has a disruption. The asthma inhaler supply chain is simultaneously highly qualified and highly concentrated.

• Origin2023

  Bespak was founded in 1961 in King's Lynn, Norfolk — originally manufacturing precision aerosol valves for consumer products (hairspray, insect repellent, aerosol paint). The company's entry into pharmaceutical MDI metering valves grew organically as pharmaceutical companies sought to apply aerosol delivery technology to asthma medication in the 1960s-1970s. The technical challenge was significant: a consumer hairspray valve can deliver variable amounts with each press without consequence; a pharmaceutical metering valve must deliver exactly the labeled drug dose (within ±15% per international pharmacopeia) consistently across thousands of actuations, across temperature and storage conditions, with no drug extractable from the elastomeric components. Bespak's accumulated manufacturing precision and regulatory experience made it the dominant supplier — its BK357 valve platform became the de facto standard for MDI design and is qualified across virtually every major pharmaceutical regulatory jurisdiction globally. The company is now part of Consort Medical, and operates as a hybrid pharmaceutical component manufacturer and pharmaceutical CDMO.
