<h1>Regulator bans cough syrup after child deaths; petition seeks national inquiry, CBI probe and mandatory NABL toxicology testing</h1> A state food-and-drugs regulator has banned sale and use of a specific cough syrup after multiple child deaths linked to the product; several other states had already imposed similar curbs. A public-interest petition in the Supreme Court seeks a court-monitored, nationally coordinated inquiry, transfer of all related FIRs to the CBI, constitution of a judicial/expert commission, and mandatory toxicological testing in NABL-accredited labs. A medical association defended an arrested prescribing physician and blamed regulatory failures by central and state drug authorities. One state has agreed to bear treatment costs; an opposition party demands judicial probe, stricter action against manufacturers and regulators, and compensation for victims' families.
