Causing serious adverse reactions: during the use of ibandronate injection, it may cause serious adverse reactions, such as cardiac diseases, including bundle branch block, myocardial ischemia, palpitations and other cardiovascular diseases, and if the titration speed is too fast, it will lead to an increase in the probability of the appearance of these adverse reactions. 2. Increase the burden on the kidneys: ibandronate injection is secreted by the kidneys and then eliminated, if the intravenous infusion is too fast, it will lead to too high a concentration of the drug per unit of time excreted by the kidneys, thus increasing the probability of drug-related renal damage.
