Analysts, on average, were also expecting a profit of 1.65 billion rupees, according to Refinitiv IBES data.

Input costs for the company, which makes the Augmentin antibiotic and T-bact oinments to fight bacterial infections, slumped 61.2% to 470.1 million rupees.

Consolidated revenue from operations, however, fell 1.7% to 8.02 billion rupees.
