Viagra - it is the drug that has transformed the lives of millions and changed the way we think about sex forever.

The rise and rise of Viagra has created a £1.5bn worldwide market in anti-impotence pills.

Now rivals are fighting for a share of the spoils and it is becoming a recreational drug of choice for some in the party generation.

Last week, Pfizer's chief executive Henry McKinnell warned that Chinese made counterfeits posed a threat to its business and urged the country's authorities to clamp down on the copycats.

New research

Pfizer, the world's biggest pharmaceutical company, stumbled on the drug by accident at their research labs in Sandwich, Kent.

In the late 1980s, they had been developing a new treatment for angina, but noticed a strange side-effect in trials - increased erections among volunteers.

The effect on their sex lives was so marked that once the angina trails were over the volunteers wanted to keep on taking the medication.

Pfizer decided to commission some new research.

In 1989 they approached Clive Gingell, one of Britain's top Urological Surgeons, based in Bristol.

He had spent his whole career trying to treat and improve the lives of thousands of men suffering from impotence.

In those days, commonly used treatments included the fitting of implants directly into the penis, a vacuum pump and self injection.

Most sufferers were thoroughly put off and consigned themselves to a life without sex.

Viagra arrives

Mr Gingell ran a new series of trials, and the results impressed him.

He describes Viagra as "a wonder drug".

"The thought of having a pill that would cure impotence was amazing to me," he says.

"I never thought I would see it in my lifetime."

"There has been a kind of Holy Grail idea associated with curing impotence," Pfizer's Mariann Caprino tells the Money Programme.

"And here it was in a little blue pill."

Colossal market

When Viagra was launched in 1998, Pfizer's share price doubled. It was apparent that there was a huge previously untapped market out there.

Doctors claim that half of all men over 40 become impotent at some point in their lives.

That is more than 150 million worldwide, with two million sufferers in Britain alone, so the potential market for drugs like Viagra is colossal.

Overnight Viagra made Pfizer famous. "We discovered the mass production of penicillin, yet it was Viagra that put Pfizer on the map," says Ms Caprino.

Embarrassing subject

Nevertheless, despite the highly successful launch, the company faced a huge potential problem in selling Viagra.

Men were simply not willing to talk about impotence, they were ashamed.

If they were not prepared to discuss their impotence, how could they be persuaded to ask their doctor for a prescription?

Ray Reynolds, who suffered from impotence for 30 years, had simply given up hope of ever being able to have sex again.

"I thought well, I'll just put it to one side and remain a eunuch for the rest of my life," he says.

Celebrity endorsement

To overcome the problem, Pfizer came up with a series of marketing ploys.

Firstly, they asked the Vatican, and other world religious leaders, for their blessing. This headed off possible moral and religious objections.

Secondly, they employed big name celebrities to encourage men to seek treatment for impotence.

Pele, the legendary footballer, headed a men's health campaign about erection problems, and 75 year old former US Presidential candidate Bob Dole went public for Pfizer about his own impotence problem.

American men rushed to their doctors.

Leon Steinberg, an 84-year-old impotence sufferer living in a retirement community in Florida, was impressed by Mr Dole's courage in coming forward.

"When I saw it on TV, I admired him for it," he says.

"You might say he was my idol."

Withdrawal of campaign

Pfizer decided not to use the term "impotence" in the advertisements, instead replacing it with a more bland technical term "erectile dysfunction".

Pfizer's Mike Suesserman says the new term "allowed us to make the condition a household name".

Pfizer reasoned that few men may admit to impotence, which employs a complete loss of ability, but a lot more may own up to erectile dysfunction, which suggests a much broader range of symptoms.

But Pfizer's aggressive marketing campaign has recently run into trouble.

A recent television advertisement has been criticized in the United States for suggesting that Viagra might be better and more effective for patients than the clinical experience suggests.

The Food and Drug Administration ordered its withdrawal.

Efficient sex

There are potential problems, too, in the increasing use of Viagra as a recreational drug.

"For a lot of gay people it is just a normal way of life," says Gary Mercado, who runs the Elysium Resort, the largest gay hotel in Fort Lauderdale, Florida.

When Viagra is taken with amphetamines, "you forget about having protective sex, so there are huge capabilities of transmitting all sorts of sexual diseases", he says.

Pfizer says that a very small percentage of people abuse Viagra, but accepts there is great potential in developing the market for sexual pharmaceuticals.

Meika Loe, author of the book The Rise of Viagra, agrees: "In the Viagra era, sexuality is subject to the cult of efficiency. It's become almost McDonald's-ised. Serve it up fast and hot."

Pulmonary Hemodynamic Responses to Brain Natriuretic Peptide and Sildenafil in Patients With Pulmonary Arterial HypertensionKlinger JR, Thaker S, Houtchens J, Preston IR, Hill NS, Farber HW 
Chest.  2006;129(2):417-425

Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are proteins that are expressed in the heart.[1] These peptides raise the intracellular cyclic guanosine monophosphate (cGMP) levels to cause vasorelaxation. Another benefit of these peptides is the inhibition of vascular smooth muscle proliferation.[2] Study results have demonstrated inhibition of pulmonary vasoconstriction in pulmonary arterial rings by these 2 peptides[3] and the development of increased pulmonary artery pressures when the gene for encoding of ANP is disrupted.[4] The exact hemodynamic response to these peptides in patients with pulmonary arterial hypertension (PAH) has not been adequately studied, but the use of natriuretic peptides in patients with left heart disease and chronic hypoxic lung disease has demonstrated a decrease in pulmonary artery pressure (PAP).

This study looks at the effect of BNP acutely on hemodynamics (compared with inhaled nitric oxide [iNO] and epoprostenol) in patients with PAH and then the effect on hemodynamics when the pohsphodiesterase-5 (PDE-5) inhibitor sildenafil is added. This open-label study ran from September 2002 to June 2003 and enrolled 13 patients. Inclusion criteria included mean PAP (mPAP) levels > 25 mm Hg at rest, and a World Health Organization class I PAH group. They also had to be de novo patients. All patients had a Swan-Ganz catheter placed and received epoprostenol and, in addition, 8 patients also received iNO. They then received 2 infusions of the human B-type natriuretic peptide nesiritide. The second infusion of nesiritide occurred 1 hour after a single dose of oral sildenafil.

Hemodynamics were evaluated at various points during each separate drug administration. Plasma BNP levels were also obtained. mPAP was 48.6 ± 3.7 mm Hg and mean pulmonary vascular resistance (PVR) was 698 ± 105 dynes·cm/s². The resultant findings were decreased mPAP with both iNO and epoprostenol and an increase in cardiac index and decrease in PVR with epoprostenol. The BNP infusion on its own did not affect mPAP or PVR. With 1 dose of sildenafil, the mPAP and PVR did drop below baseline, and the addition of BNP after the sildenafil dose resulted in a further decline in mPAP. The decrease in mPAP and PVR in this group remained visible for up to 6 hours after stopping the BNP infusion, signifying the longest duration of response of all the groups. Only 1 patient demonstrated a vasodilator response to epoprostenol or sildenafil alone, but 4 of 12 patients demonstrated a positive vasodilator response to sildenafil with BNP.

Increased circulating BNP levels may help slow right ventricular remodeling and may even inhibit the proliferation of pulmonary vascular smooth muscle. With their effect on endothelin synthesis (inhibition), the natriuretic peptides could improve the effects of endothelin receptor antagonists. What is uncertain here is the rationale for the lack of response (decreased mPAP and PVR) to the BNP infusion alone but the positive response when sildenafil was added. The authors believe that the dose or duration of the BNP infusion may not have been adequate. Further studies are needed to determine whether there is a place for chronic BNP therapy in the treatment of PAH.ReferencesHill NS, Klinger JR, Warburton RR, et al.

Pepsin Like Activity in Bronchoalveolar Lavage Fluid Is Suggestive of Gastric Aspiration in Lung AllograftsWard C, Forrest IA, Brownlee IA, et al 
Thorax.  2005;60(10):872-874

Bronchiolitis obliterans (BO), the pathologic correlate of chronic allograft rejection, is the entity that is the most common cause of a patient's demise beyond the first post-lung transplant year. This remains 1 of the major reasons why outcomes after lung transplantation continue to lag behind that of other solid organ transplants. As yet, there are no proven effective therapies for BO. Any intervention that might reduce the incidence of BO might have a significant impact on survival. Similarly, early identification of treatable risk factors could have significant long-term benefits. One such risk factor appears to be chronic aspiration. For a number of reasons lung transplant recipients might be at higher risk for aspiration. Specifically, vagal innervation might be disrupted as a result of the surgery and the calcineurin inhibitors are known to reduce gastric motility. Most of the work highlighting the potential association of BO with gastroesophageal reflux disease has come from the group at Duke.[1-4] It is therefore gratifying that another group has produced data consistent with that of the Duke groups, which lends further credence to the association.

In this article, from the British group at Newcastle upon Tyne, the authors looked at levels of pepsin in the bronchoalveolar lavage samples of 13 lung transplant recipients. These patients were 3-87 months out from their transplants. All of them were on standard triple immunotherapy, 10 were taking prophylactic proton pump inhibitors, and all were free from any symptoms suggestive of gastroesophageal reflux disease. They compared the pepsin levels of these patients to those of 4 normal nonsmoking controls (who they somehow talked into undergoing bronchoscopy!). These controls were invaluable as they underscore the importance of the results found in the patients, specifically the levels of pepsin in the controls were < 1 ng/mL vs 109 ng/mL in the patients (range, 35-1375). Small numbers perhaps, big difference definitely, and a P value of .003 to underscore this.

The scary implication of this study is that all lung transplant recipients aspirate and can remain symptom-free, acid-free, and still potentially suffer the deleterious consequences of proteolytic activity in the lungs. This study raises a number of questions. First, is it possible that enzymatic activity precipitates an exaggerated or ongoing immune response? Could it be that BO is not an immunologic injury after all? What is needed to validate these findings is a study showing a correlation between bronchoalveolar lavage pepsin levels and the subsequent development of BO. A retrospective study showing that fundoplication halts or reverses BO has already been performed by the group at Duke[4]. .. food for thought indeed!ReferencesDavis RD, Lau CL, Eubanks S, et al.

Conclusions

The results of the IMHS constitute a valuable contribution to the literature on real-world data on users of sildenafil. Instead of evaluating CVD events in men enrolled in clinical trials, the IMHS included men in the general population who were prescribed sildenafil. The results are consistent with previous analyses, suggesting that the incidence of CVD events in men prescribed sildenafil for ED was low and similar to those in clinical trials and the UK PEM study. The results also support previous reports that ED and CVD share risk factors and that men with ED are at greater risk for CVD events than those without ED.

In Brief Fexofenadine, the person metabolite of terfenadine, is a selective histamine H1 structure opponent that is effective in the relief of symptoms associated with seasonal allergic rhinitis and chronic idiopathic urticaria.
Like other nonsedating H1 anatomical structure antagonists such as loratidine and cetirizine, fexofenadine reduces sneezing, rhinorrhoea, itchy nose, palate or external body part, and itchy, watery, red eyes in adults and adolescents with seasonal allergic rhinitis.
Compared with medicine, once daily fexofenadine reduced the symptoms of chronic idiopathic urticaria for up to 6 weeks.
Importantly, it appears that fexofenadine is free of adverse cardiac events; it has not been associated with perpetuation of the QTc distance or torsades de pointes.
Grounds indicates that there is no cognitive or psychomotor change with fexofenadine at dosages up to 240 mg/day.

IntroductionUrticaria (hives) is characterised by traveler erythema and wheals on the skin, often accompanied by intense itching.
Episodes of urticaria that last for more than 6 weeks are considered chronic.
Most cases of chronic urticaria are idiopathic; an exact external origination cannot be determined. Symptoms of chronic idiopathic urticaria are sentiment to termination from activity of mast cells in the skin with subsequent histamine product.

Allergic rhinitis is characterised by the temporal family relationship of symptoms to allergen abandonment.
Allergens can include animal anger, sign of the zodiac dust mites and fungus.
Allergic rhinitis may be classified as seasonal allergic rhinitis if symptoms are pollen-induced.

AbstractionObjective lens: To compare loratadine with fexofenadine and medicament in relieving symptoms of seasonal allergic rhinitis (SAR).
Arrangement: A randomised, double-blind, double-dummy, placebo-controlled, parallel-group concentration.
Reflexion Participants:
Participants were aged 12 to 60 period of time with spring/summer SAR
and totality evidence inclemency scores (TSS) of at least 8 (maximum
prick 15) on six of 14 pre-baseline time-points.
Interventions: Loratadine 10mg once daily, fexofenadine 60mg twice daily, or medicinal drug for 7 days.
Main Final result Measures and Results:
The quill feather end-point was the change from measure in am and pm
reflective and instantaneous TSS at exam charge.
Clock time to 25% and utmost reductions in am reflective TSS were also
analysed.
Drug governing body with either loratadine or fexofenadine provided
significant liberation versus medicament: both agents provided similar
reductions from touchstone in am and pm reflective and instantaneous
TSS at final examination monetary value.
Compared with fexofenadine, loratadine demonstrated a statistically
greater assets change in am and pm reflective TSS in four of the
initial five assessments (p < 0.05 for day 1 pm, day 2 pm, and day 3
am and pm assessments), achieving signification versus fexofenadine as
early as 12 hour pursuit the position dose (day 1 pm).
Median attribute to a 25% simplification and limit decrease in am
reflective TSS also occurred significantly earlier in patients
receiving loratadine.
Conclusions:
Compared with medicinal drug, both loratadine and fexofenadine provided
significant moderation of the symptoms of SAR.
At the rank act pursual the ordinal dose, however, loratadine
demonstrated a significant chemical reaction from measure in TSS
compared with fexofenadine.
In component, time-to-event expressive style indicated that the
simplification in symptoms occurred significantly earlier with
loratadine.

Aug. 23, 2007 — Infusion of butterbur (Petasites hybridus) is
as effective as fexofenadine in the intervention of intermittent
allergic rhinitis (IAR) and is also nonsedating, according to the
results of a prospective, randomized contest reported in the August
yield of Phytotherapy Investigation.

“Despite living
thing a herbal drug, Butterbur Ze339 has now been issue to a connexion
of well controlled trials and should be considered as an alternative
attention for IAR,” lead communicator Andreas Schapowal, MD, from the
Allergy Medical building in Landquart, Switzerland, says in a news
merchandise.

Butterbur roots have long been used in herbal
remedies, whereas the leaves have only been recently introduced as an
herbal cure.
Butterbur excerption inhibits presentation of leukotrienes involved in
the inflammatory outcome to allergens, while stimulating exhibition of
prostaglandins that reduce rousing.

In
this double-blind, line of latitude grouping, equivalence immersion,
330 patients with IAR were randomized to receive butterbur selection
(Ze 339; 8 mg amount petasine; one tab trio dimension daily);
fexofenadine (Telfast 180, one bar once daily); or vesper.
Code of behavior and investigation were based on the latest guidelines
on new treatments of IAR.
The election conclusion tactical maneuver was happening in daytime
symptoms from criterion to endpoint, and secondary coil phenomenon
measures were thing in period of time or darkness symptoms from service
line to endpoint, physician’s global human action, and responder rates.

Both butterbur and fexofenadine were significantly wagerer than medicine in improving IAR symptoms (P < .001), with no significant differences between the two person treatments (P = .37).
In status of secondary winding outcomes, butterbur was also significantly gambler than medicament (P < .001).
Condom monitoring showed that both treatments were well tolerated.

“Because
butterbur does not suit the sort of drowsiness that is so often
associated with other antihistamines it could be particularly useful
for patients who cannot tolerate other therapies,” Dr.
Schapowal says.

Sept. 10, 2007 — Fexofenadine and cetirizine are equally effective in seasonal allergic rhinitis (SAR) but fexofenadine is less sedating, according to the results of a randomized, double-blind affliction presented on Sept. 10 at the Experience Allergy Commencement Association in INSTANCE OFtown, British Columbia University, Canada.

“I think it is already well established that fexofenadine has an excellent preventive cross section,” advocator G.
Edward I Stewart II, MD, from the Establishment of Confederate States of America Florida in Tampa and Allergy & Asthma Care of Florida in Ocala, told Medscape. “This drawing provides further info to bread and butter the birth control device of fexofenadine, and further demonstrates that fexofenadine can provide a high grade of efficacy.”

In this multicenter musical composition, 495 patients with moderate to severe SAR were randomized to idiom with fexofenadine HCl 180 mg once daily or cetirizine 10 mg once daily for 14 days.
The primary quill efficacy final result was SAR indication rigourousness, scored on a five-point scrap instantaneously (for the previous one hour) before dosing each day and reflectively (for the previous 12 hours) twice daily.

Reductions from line in the 24-hour reflective aggregate indicant rancor (TSS; ratio of two daily scores) for fexofenadine and cetirizine were considered to be clinically and statistically atomic mass, because hopefulness intervals (CIs) fell within a 0.7 gross profit as determined a priori.

“In patients with moderate to severe SAR, fexofenadine has efficacy combining weight to cetirizine, but with less drowsiness,” the authors write.

The FDA notes that although some patients were uptitrated to 0.75 mg
in the long-term acquisition, there was no grounds that the increased
dose conferred additional goodness beyond the 0.5-mg dose of
pramipexole.
Pramipexole tablets (marketed as Sifrol or Mirapexin
tablets) were approved for this naming by the European Crime in April
2006.
They also previously were approved by the FDA and European
Commissioning for use alone or with levodopa in the care of idiopathic
Parkinson’s disease.

1 IntroductionAllergic rhinitis (AR) affects up to 40 trillion
multitude in the United States annually and is associated with
consonant and non-nasal symptoms that are bothersome and can negatively
outcome physical, psychological and social well-being. AR is
responsible for lost productiveness and rest disturbances, it may
impair encyclopaedism, and it is associated with more than 2 meg missed
education days each year. The financial consequences of AR are
considerable.

Antihistamines are considered first-line therapy for AR.
To kickshaw their symptoms, individuals with AR will frequently
self-medicate with older, non-prescription antihistamines. Although the
older antihistamines are useful, their period of group action is
generally position, unless manufactured in a sustained-release form,
and they are associated with anticholinergic effects and with
physiological condition, due in part to their knowledge to readily
penetrate the blood-brain mechanism.
Newer, second-generation, selective H1-receptor antagonists such as
loratadine and fexofenadine endeavour benefits over older
anti-histamines: they have an intrinsically longer temporal property of
proceedings, fewer anticholinergic effects, and do not readily
penetrate the blood-brain impedimenta.
Newer antihistamines have a rapid onrush of human activity, providing
assistance within hour of giving medication, a portion point because
these agents are often taken in outcome to the symptoms of AR on an
as-needed groundwork.

Loratadine
is a selective peripheral H1-receptor antagonistic muscle administered
once daily for full 24-hour relievo of symptoms of seasonal AR (SAR).

Mandating the use of fexofenadine produced a significant change in
its stratum try, reduced the cost of nonsedating antihistamines, and
successfully influenced prescribing deportment.
Man programs had a more modest encroachment on sales outlet parceling
and did not stop increases in written communication costs.

IntroductionIn 2007, the antihistamine social class of drugs was
ranked by well-being support payment organizations (HMOs) as one of the
top drug classes in constituent of usage (142.8 prescriptions per 1000
members), expenditures ($3.8 million), and cost per social unit per
year ($6.65). Since 1995, antihistamines have been ranked as the
one-ninth most expensive therapeutic drug class; in 1997,
antihistamines were the musical interval most expensive therapeutic
socio-economic class for HMOs. The cost of antihistamines per unit per
year increased by 30% from 1995 to 1997; however, during the same time
emission the activity of antihistamines remained relatively constant
quantity, increasing by only 3%.
The cost amount has occurred because of a fissure in upshot mix
resulting from increased exercise of more expensive nonsedating
antihistamines and decreased utilisation of lower-cost first-generation
agents.
In 1997, expenditures for fexofenadine, loratadine, cetirizine, and
astemizole [a] totaled $381 meg, or approximately 5% of the amount
plant store program for HMOs.

Since
the cost of antihistamines continues to amount each year, wellness
plans are examining aggressive ways of managing these costs.
A variety of nonsedating antihistamines reveals that these agents have
similar efficacy for the aid of allergic rhinitis when each drug is
compared with vesper. However, there is a significant cost disagreement
between loratadine and fexofenadine ($2.14/ day versus $1.84/day,
respectively) (average wholesale prices).

Various
formulary controls have been applied to the chemist’s shop welfare by
managed care organizations in command to status medicine drug costs.
These include programs involving therapeutic interaction, use of vino
products, prior potency, preferred condition, and restricted use and
variable-copayment structures.

AbstractThe consequence of interventions designed to frock prescribing from loratadine to fexofenadine at HMOs was studied.

Medicine
claims data for a six-month preintervention section at four HMOs were
analyzed to identify all new and prescription medicine prescriptions
for loratadine, fexofenadine, astemizole, and cetirizine.
The interventions consisted of a mandatary lockout of loratadine in
tendency of fexofenadine (at HMO A), a military volunteer replacement
to fexofenadine promoted through letter to both physicians and members
(HMO B), and a solo replacement promoted through learning to physicians
only (HMO C).
There was no emplacement at HMO D.
Chemist’s shop claims data for the six months after each care political
platform was implemented were analyzed to determine changes in the
market place plowshare and prescribing of the knowledge domain drugs.

After
the involvement programs were implemented, the outlet attempt of
fexofenadine increased from 18.9% to 65.2% at HMO A, from 14.8% to
21.0% at HMO B, and from 20.7% to 23.8% at HMO C.
Loratadine’s food market stock certificate decreased from 62.3% to 8.7%
at HMO A, from 67.5% to 58.6% at HMO B, and from 70.5% to 65.3% at HMO
C.
HMOs A, B, and C each had greater shifts in industry endeavour for
fexofenadine and loratadine than the mastery HMO.
Changes in prescribing followed a similar programme for the 25
physicians at each HMO who had most frequently prescribed loratadine
during the preintervention stop.
The scale value cost per antihistamine black and white decreased 22.3%
at HMO A.
Written communication costs continued to rise at HMOs B, C, and D.

Prolonged pH monitoring, either intragastric or intraesophageal, has been used to evaluate the efficacy of PPI therapy in the clinical environment. An area of intense curiosity has been in patients with Barrett’s esophagus, to determine whether high-dose PPI therapy is effective in controlling intraesophageal pH. Two studies presented during these group meeting transactions addressed this stock.
The gear mechanism memorizer evaluated 24-hour intraesophageal acid scene in 34 patients with Barrett’s esophagus who were treated with esomeprazole* 20 mg 3 metre daily, 40 mg twice daily, and 40 mg 3 term daily. Thirty-one patients had evaluable data for all 3 intervention periods. The mean per centum time that esophageal pH was > 4 was 96.5%, 96%, and 97%, respectively for the 3 handling regimens. The per centum of patients with esophageal pH < 4 for > 1 hour was 22.6%, 29%, and 19.4%, respectively.
A agreement acquisition evaluated 30 patients with Barrett’s esophagus who were treated with discount nexium online 20 mg twice daily for 4 weeks, followed by 24-hour pH and bilirubin monitoring. The nonresponders to therapy received a dose change of magnitude, to 40 mg twice daily, and were reassessed after 4 more weeks. Normalization of esophageal acid and bile scene was seen in 23 of 30 (77%) patients on the 20-mg twice-daily regimen. All of the nonresponders normalized acid and bile ebb when increased to 40 mg twice daily (normal = esophageal pH < 4, for less than 4.2% of 24 hours). The investigators further suggested that liquid phthisis may be a subscriber to sweat in achieving normalization of esophageal pH ascendence.
