The unlawful manufacture, importation, advertising and distribution of unregistered medicines pose a serious risk to public health," Sahpra CEO Boitumelo Semete-Makokotlela said..According to Sahpra, inspectors uncovered extensive regulatory failures during the raid, including what it described as the illegal importation of active pharmaceutical ingredients (APIs), inadequate sterile manufacturing conditions and the absence of proper analytical testing to confirm product quality, potency and purity."We will not hesitate to act to protect patients and safeguard the integrity of South Africa's regulatory system," Semete-Makokotlela said.Inspectors allegedly found dust contamination, unsuitable equipment and no validated heating, ventilation and air-conditioning system required for sterile pharmaceutical production.Sahpra also raised the alarm over the absence of a pharmacovigilance system to monitor adverse drug reactions linked to the products, adding that it has already received reports of adverse events, including hospitalisations associated with some of the medicines under investigation.Compounding this is the practice of preparing customised medicines for individual patients, which is permitted under South African law only when done on the basis of a valid prescription and within tightly controlled parameters..Sahpra said the operation has moved beyond patient-specific compounding into the broader commercial manufacturing and marketing of GLP-1 medicines, particularly for weight management.As part of the enforcement action the regulator seized all finished products containing semaglutide, tirzepatide and related combinations found on site. The company has also been instructed to initiate a full recall of affected products distributed through healthcare providers, pharmacies and other channels.The SAPC said disciplinary action against pharmacy professionals implicated in the matter will follow."Unlawful manufacturing, promotion and distribution of unregistered GLP-1 medicines for weight loss is a serious violation of the law and a direct threat to public safety," SAPC CEO Vincent Tlala said."Pharmacists and pharmacy support personnel found selling, compounding or distributing these unregistered medicines risk severe disciplinary action, including possible removal from the register. The council will not tolerate any conduct that compromises patient safety or the integrity of the pharmacy profession.".This article was first published on Business Day and is republished with permission.Sign up for your early morning brew of the BizNews Insider to keep you up to speed with the content that matters.
