Catalysis of the transfer of putrescine from one side of the membrane to the other. Putrescine is 1,4-diaminobutane, the polyamine formed by decarboxylation of ornithine and the metabolic precursor of spermidine and spermine. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: putrescine(out) + ornithine(in) = putrescine(in) + ornithine(out). Catalysis of the transfer of amines, including polyamines, from one side of the membrane to the other. Amines are organic compounds that are weakly basic in character and contain an amino (-NH2) or substituted amino group. Catalysis of the transfer of polyamines, organic compounds containing two or more amino groups, from one side of the membrane to the other. Catalysis of the reaction: ATP + H2O + putrescine(out) = ADP + phosphate + putrescine(in).
