Common Name

Enprofylline

Class

Small Molecule

Description

Enprofylline is a derivative of theophylline which shares bronchodilator properties. Enprofylline is used in asthma, chronic obstructive pulmonary disease, and in the management of cerebrovascular insufficiency, sickle cell disease, and diabetic neuropathy. Long-term enprofylline administration may be associated with elevation in liver enzyme levels and unpredictable blood levels.
