BIOAVAILABILITY VS CONVENIENCE: A COMPARATIVE PHARMACEUTICO-CLINICAL ANALYSIS OF CHURNA (POWDER) AND VATI (TABLET) DOSAGE FORMS IN AYURVEDIC THERAPEUTICS

The modernization of Ayurvedic pharmaceutics has seen a massive shift from traditional powders (Churna) to compressed tablets (Vati/Gutika), driven primarily by patient compliance and convenience. However, this shift raises critical pharmacokinetic questions regarding efficacy, onset of action, and bioavailability. This paper analyzes the comparative pharmacodynamics of Churna and Vati, exploring the "Convenience Tax"—the potential loss of therapeutic potency due to compression, excipients, and the bypassing of oral sensory signaling (Rasa-Bodhana). We argue that for specific therapeutic indications, particularly Deepana (appetizer) and Pachana (digestive), the tablet form significantly compromises clinical outcomes.
