Adverse drug response (ADR) has been implicated as a leading motive of morbidity and mortality globally. The superiority fee of ADRs has been pronounced to range from 0.16 to 15.7 per cent. Morbidity associated with ADRs is also widely known and reasons a huge wide variety of clinic admissions similarly, ADR associated hospitalization in emergency and intensive care devices (ICU) could be very excessive amongst high danger populace like aged populace with a couple of co-morbidities.
There are many drugs or group of drugs which can lead to drug induce diseases such as supraventricular arrhythmias related to heart. These diseases are manageable and can be treated. Pharmacist can play an important role in managing these diseases.
A supraventricular arrhythmia is an irregular heart rate that begins above the ventricles, which are the two lower chambers of the heart. Drugs may induce a variety of supraventricular arrhythmias that may be associated with symptoms like hemodynamic instability, stroke, and an increased risk of death. Also include sinus bradycardia, atrioventricular (AV) node block, atrial fibrillation or flutter, atrial tachycardia. Sinus bradycardia is defined as a sinus rate <60bpm.AV block occurs when conduction of impulses from the atria to the ventricles through the AV node is inhibited. AV block is classified as first, second and third degree.
Supra ventricular arrhythmia may be associated with a wide variety of drugs. In addition to occurring as a result of drugs administered orally or intravenously, this may be induced by drugs administered as eye drops. Numerous are associated with topical adrenergic β- receptor antagonists (β- blockers). Chronic cocaine and digoxin use has been shown to increase the odds of bradycardia and severe bradycardia.
Drug-induced arrhythmias may be caused by inhibition of automaticity of the node, slowing of sinus node conduction, or prolongation of sinus node repolarization. May result in the need for temporary or permanent pacemaker implantation.
Drug-induced disease is often preventable. When possible, drugs with the potential to inhibit sinus or AV node function should be avoided in patients with known sinus or AV node dysfunction in the absence of a functioning pacemaker.
Patients who are taking drugs with the potential to cause sinus bradycardia, sinus pauses, or AV block should be taught to monitor their heart rate daily and to consult their pharmacist or physician if heart rate falls below 50 bpm or if they experience symptoms of bradycardia or tachycardia. A reduction in dose of the offending medication may be sufficient, but in most cases hospitalization and discontinuation of therapy is necessary. The Pharmacist should keenly monitor these patients.
PATIENT INFORMATION
Pharmacist should counsel and monitor the patient. Patients should be instructed that a specific drug may cause the heart rate (pulse) to become slower. Patients should be taught to take their pulse and to monitor their heart rate daily. Patients should be instructed to consult their pharmacist or physician if their heart rate falls below 50 bpm, or if they feel lightheaded, dizzy, tired, weak, short of breath, experience chest pain, or lose consciousness.
Conclusively, a pharmacist should stay in touch with the patient and counsel them at every necessary moment. Should provide them patient education materials and tell them the pros and cons of the medicine to avoid any serious medical condition.
