A medicament dispenser comprising a canister and a drug dispensing valve, wherein one or more surfaces of said canister and/or valve has a fluorinated coating provided by a process comprising generating one or more fluorine-containing radical species and polymerising said radicals on said one or more surfaces, provided that the radicals are generated by a hot filament chemical vapour process, pyrolisation of fluoroparylene dimers, use of a photo initiator to create radicals from a fluoroacrylate or laser ablation of a fluoropolymer target. Also disclosed is a medicament dispenser comprising a canister and a drug-dispensing valve, wherein one or more surfaces of said canister and/or valve has a fluorinated coating provided by a process comprising incorporating a fluorine-containing species into a liquid or gas, depositing a fluorine-containing layer on said one or more surfaces, and thereafter optionally removing the liquid or gas.
