Trang 2Pharmaceutical Industry Conduct
Preview: Empirical evidence indicates that
competition is at work, but the industry does not exhibit perfect competition.
Trang 3Pricing Behavior
Can the brand-name firm maintain its
price once its patent expires and
generics enter?
After patent expiration, each 10% increase in the price differential for brand-name drugs
relative to generics resulted in only a 5% drop
in market share for the brand-name drug
(Hurwitz & Caves, 1988)
Average price differential between brand-name and generic firms = 127%, but brand name
market share = 63.4%.
Trang 4Pricing Behavior
The longer the brand-name drug’s
effective patent length, the more market share it preserved after patent

Trang 10A brief regulatory history
1981: industry shows interest in
advertising directly to consumers
1983–1985: FDA obtains voluntary moratorium on DTC advertising
Trang 11Promotional spending by
pharmaceutical manufacturers
Trang 12Are DTC ads reaching
consumers?
Trang 13Ads are read and acted upon
56% of Sacramento-area adults have read a DTC ad carefully from beginning to end
35% have asked their doctor for more
information because of a DTC ad
19% have asked for a prescription due to an ad
Trang 14Misconceptions abound
50% believe ads subject to prior review 43% believe only “completely safe”
prescription drugs can be marketed
DTC; 21% that only “extremely
effective” drugs can be so marketed
22% believe that advertising of
prescription drugs with serious side
effects has been banned
Trang 15Are DTC ads educational?
Trang 16The Industry Perspective
“ By greatly increasing the likelihood that patients will seek help for their medical problems and receive a safe and
effective prescribed medicine, DTC
advertising will…play a very real role in enhancing public health.”
-Alan F Holmer, President, Pharmaceutical Research
and Manufacturers of America, JAMA 281:380,1999
Trang 17A Contrarian View
“Extending the scope of already ubiquitous
promotions about ‘post-nasal drip,’ ‘unsightly rashes,’ or ‘cures for baldness’ has little to do with educating patients or relieving suffering
It will, however, inevitably drain healthcare
dollars, dramatically increase unnecessary prescribing, and strain patient-doctor
relationships.”
JR Hoffman and MS Wilkes, BMJ 318:1301, 1999

Trang 20Influence on prescribing decisions: a bi-national study
Cross-sectional cluster survey in
Sacramento (CA) and Vancouver
(CANADA)
78 primary care physicians
1431 patients (61% of those attending
on preset clinic days)
Trang 21Patient requests and physician
drugs)
Patients requesting a prescription much more likely to receive one (AOR 8.7, 95% CI 5.4-
14.2)
Trang 22Provoking clinical ambivalence
“If you were treating another similar
patient with the same condition, would you prescribe this drug?”
Percent “possibly” or “unlikely”
Rx not requested: 13%
Any drug requested: 49%
Advertised drug requested: 70%
Trang 23Summary of Katz Studies
DTC ads are reaching consumers
Education is a side effect of promotion DTCA-induced requests influence
prescribing
A true reckoning of public health
benefits and harms has not occurred

Trang 27Product Innovation
Innovation is very risky and time
consuming.
R&D process takes many years
Only a small fraction of new drug
discoveries are eventually marketed
75% of NCEs in Phase 1 go to Phase 2
36% of NCEs in Phase 1 go to Phase 3

Trang 32Cautionary note on inflation
The inflation rate calculated by BLS is based on a price index, which may
overstate the true in drug costs.

Trang 33Cautionary note on inflation
BLS “basket” undersamples new drug
products, which generally have smaller price increases than older drugs
BLS treats generics as new products, not as substitutes for more expensive drugs
BLS uses list rather than transactions prices.BLS doesn’t adjust prices to reflect quality improvements
Trang 34Are profits in the drug industry “too high?”

Trang 35Are profits in the drug industry too high?
Under standard accounting practices, R&D is written off as a current expense
But R&D affects revenues for years to come
Rate of return on investment is calculated
using an asset base that improperly excludes intangible R&D
Should capitalize R&D outlays &
depreciate them over appropriate time periods
Accounting figures overstate the rate of return on assets for drug companies
