We will typically belief that the medicines we purchase at pharmacies include what they’re presupposed to and that they have been manufactured in response to good high quality requirements. In his newest column, Dr Andy Grey zooms in on the regulatory scaffolding that permits this belief.
One of many health-related Sustainable Improvement Aim targets is to realize “common well being protection, together with monetary threat safety, entry to high quality important health-care providers and entry to secure, efficient, high quality and inexpensive important medicines and vaccines for all”. The phrase “high quality” seems twice in that focus on description, as a requirement for the healthcare providers delivered, and as a vital component of the medicines and vaccines made out there.
‘High quality can’t be examined right into a product’
There’s a truism within the pharmaceutical business that high quality can’t be examined right into a product. As an alternative, high quality is assured by the implementation of a pharmaceutical high quality system, known as present Good Manufacturing Apply (cGMP).
The first authorized enablement is supplied by the Medicines and Associated Substances Act, 1965. Part 1(3) of the Act states: “In figuring out whether or not or not the registration or availability of a drugs is within the public curiosity, regard shall be had solely to the protection, high quality and therapeutic efficacy thereof in relation to its impact on the well being of man or any animal, because the case could also be.” Proof for security and therapeutic efficacy is supplied by well-conducted medical trials. There’s a distinction, nevertheless, between registered medicines and complementary medicines. The latter require a warning on their labels stating: “This unregistered drugs has not been evaluated by the SAHPRA for its high quality, security or supposed use”. Complementary drugs producers are being progressively introduced consistent with GMP.
Proof of high quality will not be reliant solely on retrospective knowledge, on checks performed on the medicines used within the medical trials, and the design of the dosage type to be bought, but additionally on the means to make sure that each batch made will ship the identical outcomes. By requiring that each producer of a drugs is licensed by the South African Well being Merchandise Regulatory Authority (SAHPRA), the Authority can guarantee compliance with GMP. The final word sanction for not assembly GMP requirements is withdrawal of licensure and due to this fact an instantaneous cease to all manufacturing actions.
New tips
SAHPRA up to date its GMP tips in April 2026. The rule of thumb defines GMP as “a set of ideas and procedures that, when adopted, be sure that medicines and associated substances are of top of the range, security and efficacy”, and as a “system that ensures medical merchandise are persistently produced and managed in response to high quality requirements”. Echoing the truism, it states that GMP is “designed to minimise the dangers concerned in any pharmaceutical manufacturing that can not be eradicated by way of testing the ultimate product”.
GMP requires the producer to supply detailed description of the methods to be applied to doc each step within the manufacturing course of and the management measures in place to make sure high quality. These step-by-step descriptions must cowl each part included within the drugs and its packaging, the premises and tools used, in addition to the coaching and accreditation of the workers concerned within the manufacturing course of. A risk-based strategy is used, for instance differentiating between sterile and non-sterile manufacturing processes. High quality management testing throughout the manufacturing course of is critically essential.
GMP locations a whole lot of emphasis on the potential of key personnel, but additionally the way in which during which authority and accountability is assigned, accepted and documented, and the way every individual matches into the administration decision-making course of. For instance, SAHPRA’s GMP tips differentiate between the Head of High quality Management, who “ought to have the authority to determine, confirm and implement all high quality management procedures similar to authority over high quality choices, oversight of testing and outcomes, approval of high quality management documentation, laboratory administration, validation and technique management”, and the Head of High quality Assurance, who “must be a part of the decision-making course of in all issues that have an effect on the standard of merchandise together with growth, laboratory, storage, distribution, distributors and third-party contractors”. All workers engaged in manufacturing must be educated on the ideas of GMP and the precise duties assigned to them. Persevering with coaching is required, with documented coaching programmes, coaching information, and checks to verify that procedures are being adopted.
What if medicines are made exterior of SA?
That each one sounds easy, if the producer is positioned in South Africa and might simply be accessed by a SAHPRA GMP inspector. Nonetheless, nearly all of medicines consumed in South Africa are imported, and even these which are made domestically largely depend on imported energetic pharmaceutical components or drug substances.
Worldwide requirements for GMP have an extended historical past. The primary draft doc was ready by the World Well being Group (WHO) in 1968. Since 1969, compliance with WHO GMP has been the idea for the WHO certification scheme on the standard of pharmaceutical merchandise transferring in worldwide commerce. Nonetheless, there was criticism of the scheme, as certificates could be issued by nationwide regulators that aren’t thought-about to fulfill acceptable maturity requirements.
Though there’s provision for exceptions, medicines imported into South Africa must be subjected to post-importation identification and assay (testing of what it comprises) by a neighborhood, accredited laboratory, or samples must be returned to the producer or an abroad testing laboratory.
SAHPRA is a member of two key organisations which are advancing harmonisation of regulatory requirements. The Worldwide Council for Harmonisation of Technical Necessities for Prescribed drugs for Human Use (ICH) publishes in depth high quality tips. ICH Q10, as an illustration, describes the necessities for a Pharmaceutical High quality System.

SAHPRA can be a member of the Pharmaceutical Inspection Co-operation Scheme (PIC/S), which goals to pursue the “growth, implementation and upkeep of harmonised GMP requirements and high quality methods of inspectorates”. Other than its work on harmonising GMP requirements, PIC/S permits the coaching of GMP inspectors and the voluntary sharing of GMP inspection stories. PIC/S membership requires an evaluation of a regulator’s inspectorate methods and procedures, so supplies a top quality test at that degree. South African GMP adopted the PIC/S GMP information in 2006, updating that standing in 2017.
SAHPRA’s GMP inspectors should not confined to working solely inside the boundaries of the nation. In addition they examine pharmaceutical manufacturing vegetation in different nations and work along with the WHO prequalification programme to increase their attain. That mentioned, even the best-resourced regulatory authorities are struggling to cowl a globalised pharmaceutical business, with many services positioned in China and India. A latest commentary within the New England Journal of Drugs identified how few international vegetation making generic medicines had been inspected by the Meals and Drug Administration, and the issues they encountered when conducting inspections, calling for improved post-marketing surveillance.
The general public, sufferers and well being professionals can due to this fact make an inexpensive assumption that medicines produced in a cGMP-compliant manufacturing facility meet the required high quality requirements. Nonetheless, that’s inadequate by itself. Mature regulators are additionally required to have efficient post-marketing vigilance methods in place. Other than hostile occasion reporting, these methods also needs to allow the reporting of high quality issues with medicines.
Substandard or falsified medicines
Efficient surveillance of the pharmaceutical market assists within the identification of substandard or falsified (SF) medicines. The mandatory management measures additionally must be in place to allow recollects and the destruction of recognized SF medicines.
The WHO International Benchmarking Device (GBT) requires proof that “Authorized provisions and laws authorize market surveillance and management actions which embrace product sampling from totally different factors of the availability chain.” SAHPRA doesn’t function its personal testing laboratory, however contracts with a WHO -prequalified facility at North-West College. Proactive sampling of medicines from all factors within the distribution chain must be strengthened, as a part of the Nationwide Motion Plan to fight SF medicines.
Regardless of the existence of a International Surveillance and Monitoring System for SF medical merchandise (each medicines and gadgets), quantifying the dimensions of the issue stays difficult. Medical product alerts have been issued in each WHO area, affecting each sort of medical product, not solely generic medicines. They’ve been recognized in nations with well-resourced, mature regulatory methods and in nations that lack such capability. Nonetheless, clear reporting of issues recognized, corrective actions taken and regulatory interventions may also help to construct confidence that high quality assurance methods should not solely working, however are seen to be working. High quality shouldn’t must be assumed with out assurance that efficient methods are in place and appropriately monitored.
