Drugs are complex entities and many of these are temperature sensitive in nature. This entails them requiring precise and continuous temperature conditions in transit in order to retain their potency and resultant efficacy. Many lifesaving drugs including biotech products and vaccines fall under such category. Any break in the cold chain process for such drugs can lead to immediate denaturing or deterioration in their quality parameters. It is imperative that a careful consideration is given by all concerned including government agencies at the sea port, airports while providing storage space at their warehouses for such drugs.

Current bottlenecks: Currently in India there are bottlenecks at the Airports that include authorities not being able to assure cold room space despite getting advance notices from the companies about the possible unloading of large consignments of temperature sensitive products. Some of the other gaps include improper training and refresher courses for some of the handling staff who handles such products at the Airport. Storage of Pharmaceutical products along with meat and food products is against the GMP norms.

Lack of special temperature control:

Cold Chain Medicines require special temperature controlled Cold storage. There are two commonly recommended temperatures specified on labels on cold chain products:

1. Products requiring temperature between 2 to 8 degree centigrade
2. Products requiring temperature around -10 to -20 degree centigrade

Cold Chain is an uninterrupted series of storage and distribution activities which maintains required temperature range of 2 to 8 degree centigrade or -10 to -20 degree centigrade as per product requirement.

Ensuring the right product quality:

Proper Cold Chain Management of pharmaceuticals will ensure that the right quality of such products is maintained not only during storage but during transportation also to meet right regulatory specifications. There is a greater focus and stringent regulatory guidelines and standards today in the developed markets around the world on strict adherence to right storage and transportation process for cold chain sensitive pharmaceuticals.

It should be kept in mind always that Cold Chain products are mostly sensitive biological substances that can become less effective or lose potency if not properly stored.
Some examples:

Products requiring 2 to 8 degree storage will not be effective if:

i. They are frozen or stored below 2 degree centigrade
ii. Exposed to temperatures above 8 degree centigrade
iii. Exposed to direct sunlight or fluorescent light

The loss of potency is cumulative and irreversible. If products are exposed to conditions outside the established range, the quality may be adversely affected, reducing their assigned shelf life, diminishing their effectiveness or making them ineffective. The exposed product may look the same – the loss of potency may not be visible.

Quality of storage is critical:

Quality of storage and handling of Cold Chain Pharmaceutical products at Airports and Seaports in the course of Export from or Import into India requires special care and attention. Since multiple products are stored and handled at Seaports/ Airports, personnel may not be able to appreciate the special need for Cold Chain Pharmaceuticals Storage & Handling. Thus, there should be Standard Operating Procedures (SOPs) for storage and handling of pharmaceuticals laid down by the Port Management authorities, so that the personnel handling pharmaceuticals strictly adhere to the pre-set norms.

Rapidly growing demand of cold-Chain facilities:

Pharmaceutical Products for which efficient Cold Chain facilities are required are rapidly growing in numbers. In its movement across the supply chain from the manufacturers to the patient, the medicines are handled and stored by various stakeholders like transporters, Airports, Sea ports, Distributors, Stockists, Retailers etc. Since the storage and handling of Cold Chain Pharmaceutical Products are unique, an uninterrupted Cold Chain is to be maintained in the entire supply chain network without any discontinuity, even for a short while, so that medicinal products of high quality reach the patients, always. Thus it is very important for all concerned stakeholders to ensure maintenance of proper Cold Chain facility.

Currently no ‘Pharma Zones’ in India:

At present there are no ‘Pharma Zones’ in India. However, Mumbai International Airport Private Limited (MIAL) has created 4 new cold rooms for pharmaceuticals and Delhi International Airports Limited (DIAL) has reported to have assured that the new Cargo Terminal, which is expected to be commissioned later in the year, will have around 4000 square metres of additional cold room capacity compared to the current cold room capacity of 400 square metres. Similarly, MIAL has agreed for a dedicated Cold Room facility for Pharmaceutical Products in the proposed new set–up.

The serious Concern continues:

Poor cold room storage facility at the country’s major airports and seaports is indeed an ongoing serious concern.

Unfortunately, even today, pharmaceuticals and bio-pharmaceuticals are, by and large, treated like just any other common product at our ports. It is high time, the authorities should note that due to inadequate storage and handling of these lifesaving drugs at ports, high dwell time and dispersed multiple authorities from whom clearances are required, the quality of these products may get adversely affected exposing the user patients at a great risk. The absence of a temperature monitoring mechanism in such facilities adds to the concern.

Recent Plan of “Pharma Zones” in India:

The DCGI has planned a separate dedicated controlled environment – ‘Pharma Zone’, within the cargo premises at Airports and Sea Ports for proper storage of Pharmaceutical products in line with Good Manufacturing Practices and Good Distribution Practices so as to assure the quality, safety and efficacy of Pharma products, which are to be either imported or exported.

Need for outsourcing Cold Chain services:

In the developed markets of the world there are private cold chain storage and third party logistics providers to offer contract logistics and storage services especially to cater to the growing demands Biopharmaceutical segment, which is the fastest growing manufacturing sector within global pharmaceutical industry.

Thus it is expected that spend of the Biopharmaceutical companies towards outsourcing of cold chain facilities will grow by over 10 – 15% for the next three to five years in the developed markets. India being the second largest producers of Biopharmaceuticals after China, similar opportunities exist in the country.

In India some renowned international courier companies like DHL and World Courier have been reported to have developed an efficient cold-chain management process, especially for the pharmaceutical companies to maintain the cold chain in their logistics network.

Conclusion:

An efficient cold chain infrastructure and its efficient management within the country will help immensely to Indian domestic pharmaceutical companies as they are exploring more and more opportunities to export pharmaceuticals in the global market. To achieve this objective modern cold chain warehouses, their efficient management as per regulatory guidelines will play a key role in ensuring right product quality standard.

Over a period of time cold-chain management practices of global standards will be required to achieve this goal. Currently for both import and export of cold-chain sensitive pharmaceuticals, as indicated, before, this area in particular poses to be one of the key challenges encountered by the industry to maintain high product quality during shipment. Individual pharmaceutical companies like Eli Lilly, India have their own vehicles equipped with cold-chain management systems for transportation of their cold chain sensitive products.

Greater initiative by the DCGI in this area in collaboration with the pharmaceutical industry as a whole, sooner, is absolutely essential, for the patients’ sake.
