Mechanism and action
Claritin: Loratadine selectively blocks peripheral H1 histamine receptors, antagonising histamine effects during allergic reactions. Thalitone: Chlorthalidone blocks the sodium-chloride symporter in the distal convoluted tubule of the kidney, reducing sodium reabsorption and producing modest diuresis.
When Claritin is preferred
Claritin is approved in adults and children for the treatment of seasonal and perennial allergic rhinitis and chronic idiopathic urticaria.
When Thalitone is preferred
Thalitone is approved for hypertension and oedema in heart failure, hepatic cirrhosis or nephrotic syndrome.
