The health sector has new drugs in place e.g. thalidomide. In addition, some old drugs like digoxin are still in use. However, the drug in use currently has seen 20 years of progress. A substantial improvements is seen in the classes of long-established drugs e.g. the antipsychotics and atypical. Other new classes which have come up e.g. the statins drugs do offer great milestone. Alzheimer’s is among the disease that went for years without medications. Nevertheless, today it has treatment and prevention.
1980s saw the development of HIV/AIDS. To date, research is being done to find its curative measure. ii. Process of a new drug approval Just like other countries, US have a formal system that approves marketing in terms of advertisement or promotion in reference to new drug. US standards of drug approval are just like in other countries. However, the progression may differ from a nation to the other Dickson & Gagnon, 2009. On the other hand, advertisements in conjunction to other logistics that are required to ensure a new drug reaches the target client; adds weight to the consumer’s cost.
This is because; firms will rate their sales to get returns on their expenses during production and marketing Dickson & Gagnon, 2009. Figure 1 below show drug approval process. From figure 1, there is clear indication as to why drug approval is time consuming and the process is complex. In 1960 the average approval stretch for a new drug was 7.9 years. This time had mounted to 12.8 years by the time the clock ticked 1990s see figure 2. The reason for this time increment can be counted from clinical trial period increase i.e. New Drug Application (NDA) submission takes time for a new drug to be filed for investigation.
The reasons for this fact are: a) The specifity of a particular disease; the investigation is being carried on (DiMasi, 2001). b) Clinical trials in phase II and III has risen by 118% and 51% procedures on average per client respectively (DiMasi, 2001). c) The increased challenges of getting and recruiting subjects to carry on clinical trials Dickson & Gagnon, 2009. d) Currently, the clinical trials require more study subjects Dickson & Gagnon, 2009. e) There is increase in regulatory requirements Dickson & Gagnon, 2009. f) Data collected form different sources is supposed to be converged to a minimum of two points.
Previously, this time was about 10-20 years for a new drug development. This time averages 9 to 12 years. In the last 20 years, this duration has shot up following the requirements of regulatory, complexity and lengthened clinical trials needed for chronic illness Dickson & Gagnon, 2009. g) iii. Risk component DiMasi, 2001, There is an increased risk in the pharmaceutical companies. This results from: a) The Economic Uncertainty b) Regulatory Uncertainty and c) Scientific Uncertainty.
Regulatory and scientific risks contribute to the lengthened time and economic risk. The challenge with long scientific development time means that; a competitor is likely to discover a certain drug first. The unfortunate innovator therefore ends up being a loser. The time required for innovative drug approval also may result to regulatory uncertainty. As a result, due to lack of clarity of market approval of a new drug there is product delay in marketing. How to reduce these risks Pharmaceutical corporations are now realizing the need to work only on promising drugs and discontinue less assuring ones.
To achieve this, they look at how cost effective a drug is going to be Dickson & Gagnon, 2009. Another measure is first reviewing how the drugs entering R&D get approved for marketing. E.g. anti-infective drugs has had highest approval rate of 28.1% since 1983 while CNS (Central Nervous System) has had the lowest rate of 14.5%. This show that new drug development is full of risk since the difference of highly rated and lowest rated drug is quite minimal Dickson & Gagnon, 2009. Summary on risks Business environment risk results from a prolonged period of discovery and approval of a NDA.
