Based on an ongoing and systematic analysis of all available evidence by CredibleMeds' Scientific Review Board, CredibleMeds® places drugs into broad categories based on whether each can cause QT prolongation or TdP. Because these actions are highly dependent on the circumstances of each drug’s use AND each patient’s clinical characteristics, this is not an attempt to rank-order the drugs within each category. Therefore, it is not recommend that these lists be used to rank-order the drugs for their relative toxicity.
Known Risk of TdP
These drugs prolong the QT interval AND are clearly associated with a known risk of TdP, even when taken as recommended.
Possible Risk of TdP
These drugs can cause QT prolongation BUT currently lack evidence for a risk of TdP when taken as recommended.
Conditional Risk of TdP
These drugs are associated with TdP BUT only under certain conditions of their use (e.g. excessive dose, in patients with conditions such as hypokalemia, or when taken with interacting drugs) OR by creating conditions that facilitate or induce TdP (e.g. by inhibiting metabolism of a QT-prolonging drug or by causing an electrolyte disturbance that induces TdP.)
Drugs to Avoid in Congenital Long QT
These drugs pose a high risk of TdP for patients with CLQTS and include all those in the above three categories (KR, PR & CR) PLUS additional drugs that do not prolong the QT interval per se but which have a Special Risk (SR) because of their other actions.
