Consolidated profit before tax dropped to 1.90 billion rupees ($23.23 million) for the quarter ended March 31, from 2.08 billion rupees a year earlier, the Indian unit of UK's GSK Plc said in an exchange filing.

Revenue from operations at the maker of Augmentin antibiotic and T-Bact ointment fell 2.7% to 7.87 billion rupees.

"A robust underlying volume growth was offset by the impact of National List of Essential Medicines (NLEM) 2022," the company said.

GlaxoSmithKline's Ceftum and T-Bact, used to treat bacterial infections, were included in the NLEM list, which mandates those medicines to be sold below a price ceiling set by a government pricing body.

In March, the company said the revenue share of drugs impacted by the pricing cap was at 42% so far in 2023, up from 33% in 2022.

The company plans to mitigate the impact of the price caps by boosting sales volumes of its Ceftum, T-Bact and Augmentin.

Separately, the company recommended a dividend of 32 rupees per share.

Shares of the drugmaker closed 0.43% higher before the results, compared with a 0.45% fall in the benchmark Nifty Pharma index.
