Adverse drug reactions lidocaine

A study in 6 healthy subjects receiving 30-hour infusions of lidocaine at a rate of 2 mg/minute found that pretreatment with propranolol 80 mg every 8 hours for 3 days raised the steady-state plasma lidocaine levels by 19% (from 2.1 to 2.5 micrograms/mL) and reduced the plasma clearance by 16%. Other similar studies have found a 22.5 to 30% increase in steady-state serum lidocaine levels and a 14.7 to 46% fall in plasma clearance due to the concurrent use of propranolol. Two cases of lidocaine toxicity attributed to a lidocaine-propranolol interaction were revealed by a search of the FDA adverse drug reaction file in 1981. A further case of lidocaine toxicity (seizures) has been described in a man on propranolol after accidental oral ingestion of lidocaine for oesophageal anaesthesia. High serum levels of lidocaine were detected. ... [Pg.263]

The answer is e. (Hardman, pp 858-874.) Because verapamil, a Ca channel blocker, has a selective depressing action on AV nodal tissue, it is an ideal drug for both immediate and prophylactic therapy of supraventricular tachycardia (SVT). Nifedipine, another Ca channel blocker, has little effect on SAT Lidocaine and adenosine are parenteral drugs with short ha If-lives and, thus, are not suitable for prophylactic therapy. Procainamide is more suitable for ventricular arrhythmias and has the potential for serious adverse reactions with long-term use. [Pg.121]

Antiarrhythmic therapy carries with it a number of risks. In some cases, the risk of an adverse reaction is clearly related to high dosages or plasma concentrations. Examples include lidocaine-induced tremor or quinidine-induced cinchonism. In other cases, adverse reactions are unrelated to high plasma concentrations (eg, procainamide-induced agranulocytosis). For many serious adverse reactions to antiarrhythmic drugs, the combination of drug therapy and the underlying heart disease appears important. [Pg.294]

Mexiletine is similar to lignocaine (lidocaine) but is effective by the oral route (t) 10 h). It has been used for ventricular arrhythmias especially those complicating myocardial infarction. The drug is usually poorly tolerated. Adverse reactions are almost universal and dose-related and include nausea. [Pg.501]
