An Update on Calcium Channel Blocker Toxicity in Dogs and Cats
The widespread use and availability of calcium channel blockers in human and veterinary medicine pose a risk for inadvertent pet exposure to these medications. Clinical signs of toxicosis can be delayed by many hours after exposure, with lethargy, hypotension, and cardiac rhythm changes as the predominant signs. Prompt decontamination and aggressive treatment using a variety of modalities may ...
Calcium channel blockers are becoming increasingly popular in veterinary medicine. Originally reported in 1985 for the treatment of atrial fibrillation in the dog, these drugs are now used to treat cats with hypertrophic cardiomyopathy (HCM) and, more recently, for treatment of systemic hypertension.'-5 Calcium channel blockers vary in location of binding sites, potency, and tissue specificity ...

Such details provide a deeper understanding and appreciation for Canine Ion Channel Blockers Treatment.
Calcium channel blockers In human heart failure patients with systolic dysfunction, calcium channel antagonists may worsen symptoms and increase mortality. 3 The mechanism for the adverse effects is unclear. Calcium channel antagonists may result in an increase in the negative inotropy.

Amlodipine Besylate Amlodipine besylate, a dihydropyridine calcium- channel blocker with vascular selectivity, is the preferred medication for treatment of systemic hypertension. Several studies have documented the eficacy of oral amlodipine in decreasing arterial blood pressure in both hypertensive cats1-4 and dogs.5 Amlodipine also can be used for crisis therapy (see Hypertensive Crisis ...
Antiarrhythmics for Use in Animals
Dosages of quinidine gluconate in dogs are 6-20 mg/kg, IM, every 6 hours, or 6-20 mg/kg, PO, every 6-8 hours; and in horses, 1-1.5 mg/kg, IV, every 5-10 minutes. Individualized treatment is necessary because of notable pharmacodynamic variation among animals and the potential for toxic effects.
Calcium channel blockers (CCBs) are a commonly used group of drugs in both human medicine since the 1960s and in veterinary medicine since the 1980s.1,2 They are defined by their ability to block the slow, or long-lasting (L-type), calcium channels , which are found primarily in cardiac and arterial smooth muscle tissues and to a much lesser ...
Key Details About Canine Ion Channel Blockers Treatment
In this review, we provide an introductory overview of the major cation ion channels : potassium channels , sodium channels and calcium channels , describe their venom-derived peptide modulators, and how these peptides provide great research and therapeutic value to both basic and translational medical research.
Despite causing similar degrees of repolarization delay as the selective I (Kr) blocker dofetilide, the combined ion-channel blocker AZD1305 induces less repolarization instability and has a lower ventricular proarrhythmic potential in the remodeled dog heart.
