An object of the present invention is to provide a glass for pharmaceutical containers, which is resistant to delamination and has excellent processibility. The glass for pharmaceutical containers of the present invention comprises, in mol% on an oxide basis, 70 to 81% of SiO 2 , 4 to 12% of Al 2 O 3 , 0 to 5% of B 2 O 3 , 5 to 20% of Li 2 O + Na 2 O + K 2 O, 0.1 to 12% of Li 2 O, 0 to 4% of CaO, 0 to 1% of SrO, and 0 to 10% of MgO + CaO + SrO + BaO. The glass has a hydrolytic resistance of Class 1 in a test in accordance with the European pharmacopoeia.
