Cycloalkylalkylamines

Propylhexedrine, sold under the brand name Benzedrex among others, is an alkylamine primarily utilized as a topical decongestant. Its main indications are relief of congestion due to colds, allergies, and allergic rhinitis. Propylhexedrine was first used medically in 1949, with the release of Benzedrex by Smith, Kline & French, and it has been used, mainly within the United States, since then.

Cyclopentamine (trade names Clopane, Cyclonarol, Cyclosal, Cyklosan, Nazett, Sinos, among others) is a sympathomimetic and vasoconstrictor drug of the alkylamine family and related to the arylalkylamines. Cyclopentamine was indicated in the past as an over-the-counter (OTC) medication for use as a nasal decongestant, notably in Europe and Australia, but has now been largely discontinued.
