Development and Evaluation of Effervescent Tablets with Caffeine, Green Tea, and Lemon Extract

Effervescent tablets enhance oral drug delivery by providing rapid onset and increased bioavailability. This research focuses on formulating and evaluating an effervescent tablet containing caffeine, green tea, and lemon extracts, optimized in Batch F2. Detailed preformulation studies were conducted, followed by tablet preparation using direct compression. Evaluation parameters included weight uniformity, hardness, friability, disintegration, and dissolution rates. Batch F2 displayed optimal results, with over 85% dissolution within 10 minutes, indicating effective bioavailability. These findings suggest that effervescent tablets enriched with botanical extracts are viable for therapeutic and health supplement applications
