1. A method of making a coated pharmaceutical container, the method comprising the steps of:
forming a glass tube;
forming the glass tube into a pharmaceutical container comprising an interior surface and an exterior surface, wherein the pharmaceutical container comprises a glass composition that has Class HGA1 hydrolytic resistance when tested according to the ISO 720 testing standard; and
applying a coating to the exterior surface but not on any portion of the interior surface, wherein the coating comprises a polymer;
wherein:
the coating has a coefficient of friction less than or equal to 0.7, wherein the coefficient of friction is a maximum coefficient of friction measured relative to a second pharmaceutical container in a vial-on-vial testing jig under a normal load of 30 N, the second pharmaceutical container formed from the same glass composition and comprising the same coating and subjected to the same environmental conditions prior to measurement of the coefficient of friction;
the coated pharmaceutical container is thermally stable after heating to a temperature of at least 260° C. for a time period of 30 minutes; and
the coating has a thickness of less than 100 nm.
