Ambrisentan: A New Drug For Pulmonary Arterial Hypertension

A New Drug for PAH: Clinical Pharmacology of Ambrisentan

In June 2007, the FDA approved ambrisentan (LETAIRIS) for the once-daily treatment of PAH to improve exercise capacity and delay clinical worsening.

Ambrisentan, a diphenyl propionic acid derivative ( Figure 1. PubChem CID:6918493), represents a valuable addition to the treatment alternatives for this orphan disease, which include prostacyclin (Flolan), inhaled nitric oxide, iloprost (a prostacyclin analog), sildenafil (a PDE5 inhibitor), and conventional Ca++ channel blockers (e.g., verapamil and nifedipine). Ambrisentan is orally active and similar to an existing drug, bosentan;[5] both are competitive inhibitors of endothelin receptors and are termed endothelin receptor antagonists (ERAs). However, bosentan lacks the receptor selectivity of ambrisentan. Ambrisentan exhibits ∼100-fold greater selectivity for endothelin receptor A (ETA) as compared to endothelin receptor B (ETB) [Ki = 0.6 nM for the human ETA receptor, 49 nM for the ETB receptor].[4] This moderate selectivity for the ET receptor may provide therapeutic advantages compared to bosentan. A common adverse effect of ERAs is the propensity to impair liver function in some patients. Thus, ambrisentan is not recommended for use in patients with moderate or severe hepatic impairment since it may cause additional liver damage.[6] Liver aminotransferase enzymes (ALT and AST) must be measured before initiation of therapy and at least monthly thereafter during therapy. The drug is an FDA category X pregnancy drug and is contraindicated in women who are or who may become pregnant. It is not known whether the drug is secreted in milk, therefore nursing mothers should not breastfeed while receiving the drug. Because of the risks of liver injury and birth defects, ambrisentan is only available through the Letairis Education and Access Program (LEAP); only prescribers and pharmacies registered with LEAP may prescribe and dispense the drug, and only patients enrolled in and meeting all conditions of LEAP may receive the drug (for enrollment information, call 866-663-5327).

Adult dosing is initiated with 5 mg once daily, and if tolerated, dosing is increased to 10 mg once daily. Although early clinical trials showed no significant differences in beneficial effects using different doses of ambrisentan (1-10 mg) for patients with PAH,[7] the results of two recent clinical trials, ARIES-1 and ARIES-2, showed a dose-dependent improvement in 6-minute walk distance with once a day ambrisentan after 12 weeks. The absolute bioavailability of ambrisentan in humans is unknown, but is ∼90% in dogs.[7a] Bioavailability is unaffected by food. The drug is rapidly absorbed after oral administration with peak plasma concentrations occurring between 1.7 and 3.3 hours. The terminal half-life is about 15 hours, but after long-term daily dosing the effective half-life is about 9 hours.[49] At steady-state, mean trough concentrations of drug are ∼15% of mean peak concentrations. The drug is highly bound to plasma proteins and elimination is primarily by non-renal pathways. In vitro data indicate ambrisentan is a potential substrate of P-glycoprotein (P-gp), the Organic Anion Transport Protein (OATP), CYP3A4, CYP2C19, and uridine glucuronosyltransferases (UGTs) 1A9S, 2B7S, and 1A3S. Because in vivo data regarding drug interactions of ambrisentan with strong inhibitors or inducers of these transporters and metabolizing enzymes are very limited, caution is advised in co-administering drugs known to affect these entities. Concomitant administration of ambrisentan with warfarin in PAH patients had no effect on PT or INR; no adjustments in dose of warfarin or ambrisentan are required when co-administered.[49] Similarly, no dose adjustments are required when ambrisentan is co-administered with sildenafil.[49] Available in vitro and in vivo pharmacokinetic data indicate hepatic impairment is likely to prolong the elimination of ambrisentan. The drug is not recommended for patients with moderate to severe liver disease, and patients with mild pre-existing hepatic impairment may require reduced dosing. Based on clinical data, no dose adjustment is required in patients with mild to moderate renal impairment, but data in patients with severe renal disease are currently unavailable.[49]

Clinical studies have indicated ambrisentan and other ERAs cause a decrease in hemoglobin and hematocrit during the first few weeks of therapy, which then stabilizes. The cause of the decrease in hemoglobin is not known, but is not due to bleeding or hemolysis. Hemoglobin measurements are required prior to ambrisentan therapy and monthly thereafter. Another ERA class effect is peripheral edema, but this is also a consequence of PAH. In the clinical studies with ambrisentan, there was an increase in peripheral edema in patients taking 5 or 10 mg daily compared to placebo, but this was typically mild to moderate in severity. Most other adverse drug reactions seen in the clinical studies were mild to moderate; discontinuation of treatment due to adverse events other than those related to pulmonary hypertension was similar for drug and placebo (∼2%).[49]Pathophysiology of PAH

PAH is defined hemodynamically as a mean pulmonary arterial pressure of =25 mmHg with a pulmonary capillary wedge pressure of =15 mmHg, both measured at rest by right-heart catheterization. Elevated pulmonary arterial pressure in PAH patients is caused by increased pulmonary vascular resistance (PVR) as a result of severe pulmonary vascular remodeling, sustained pulmonary vasoconstriction, and in situ thrombosis in small arteries. Excessive vascular remodeling, manifested by obliteration of small arteries, muscularization of precapillary arterioles, intimal lesions and fibrosis, and the plexiform lesion, is the major contributor to the elevated PVR in most patients, while sustained vasoconstriction contributes to the elevated PVR in 15-20% of PAH patients. Vasoconstriction, by itself, is also a stimulus of pulmonary artery smooth muscle cell hypertrophy and hyperplasia. Loss of pulmonary vascular compliance and increased PVR due to pulmonary vascular remodeling leads to progressively pronounced pulmonary hypertension and has indeed been found to be the predominate pathological finding in idiopathic PAH.[1]Endothelin and Endothelin Receptors in PAH

Endothelin (ET) is a 21-amino acid peptide exhibiting three isoforms ET-1, ET-2, and ET-3 ( Figure 2, Figure 3, PDB ID: 1EDN). ET-1 is a potent vasoconstrictor, mitogen, and proinflammatory mediator. In the pulmonary circulation, increased ET-1 plasma levels correlate with changes in arterial pressure.[9,10] In patients with PAH, the level of ET-1 in the plasma and pulmonary microvasculature is increased as much as 10-fold and its concentrations correlate with pulmonary artery pressure and severity of disease.[10-13] The actions of endothelins in the vasculature are mediated by at least three different G-protein coupled receptors, the ETA receptor and two ETB receptor subtypes, ETB1 and ETB2.[20,21] ETA receptors bind ET-1 and ET-2 with a higher affinity than ET-3 (order of potency: ET-1 = ET-2 > ET-3), while ETB receptors have similar affinities for all three endothelin isoforms (i.e., order of potency is ET-1 = ET-2 = ET-3). ETA and ETB are functionally expressed in various tissues with different proportions. There are at least two studies demonstrating that expression of smooth muscle cell ETB receptors is increased in PAH,[13,16] while other studies demonstrate that the endothelial ETB receptors are downregulated or dysfunctional.[17,18] Furthermore, the endothelial ETB receptor-mediated ET clearance remains intact in patients with idiopathic PAH, and only modestly reduced in patients with PAH associated with connective tissue diseases (e.g., scleroderma).[19] These studies seem to suggest that increased ET concentration in the plasma and lung tissue serves as an important stimulus for sustained pulmonary vasoconstriction and excessive vascular remodeling in patients with PAH. Selective blockade of the endothelin receptors (e.g., ETA) that mediate contractile and mitogenic effects on PASMC, while maintaining (or preserving) the function of the endothelin receptors (e.g., ETB) that cause vasodilative effects and induce ET-1 clearance, is therefore a good strategy for designing therapeutic approaches for patients with PAH, and may offer more benefits than nonselective ETA/ETB antagonists.

Antidepressants

Effexor XR (venlafaxine hydrochloride) Extended Release Capsules

Manufacturer: Wyeth-Ayerst

Drug Approval Classification: Supplemental New Drug Application (Approval Date: 02/11/03)

New Indication:Effexor XR (venlafaxine hydrochloride) is now indicated for the treatment of social anxiety disorder, also known as social phobia, as defined in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV [300.23]).

Social anxiety disorder is characterized by a marked and persistent fear of 1 or more social or performance situations that necessitate exposure to unfamiliar people or to possible scrutiny. Exposure to the feared situation usually provokes anxiety, which may approach the intensity of a panic attack. The feared situations are avoided or endured with intense anxiety or distress. The avoidance, anxious anticipation, or distress in the feared situation(s) interferes significantly with the person's normal routine, occupational or academic functioning, social activities or relationships, or there is a marked distress about having the phobias. Lesser degrees of performance anxiety or shyness generally do not require psychopharmacologic treatment.

Dosing: For the treatment of social anxiety disorder, the recommended starting dose for Effexor XR is 75 mg/day, administered in a single dose. In clinical trials, Effexor XR was started at a dose of 75 mg/day and the maximum dose was 225 mg/day.

The Effexor XR labeling recommends titrating the starting dose at 37.5 mg/day for 4 to 7 days, to allow new patients to adjust to the medication before increasing to 75 mg/day.

Clinical Summary: A total of 551 adult patients with social anxiety disorder were studied in two 12-week double-blind, parallel group, multicenter, placebo-controlled, flexible-dose studies. The efficacy of long-term treatment with Effexor XR beyond 12 weeks has not been studied. The dose of Effexor XR ranged from 75-225 mg/day.

Efficacy was assessed with the Liebowitz Social Anxiety Scale (LSAS). Effexor XR was significantly more effective than placebo on change from baseline to endpoint on the LSAS total score.

Adverse Effects: The most common adverse events reported in the social anxiety disorder clinical trials included: nausea (4%), insomnia (3%), headache (2%), and somnolence (2%). Impotence was reported in 3% of the men who participated in the trial (n = 158).Reference

Statins Improve Erectile Performance Of Some Men Who Previously Did Not Respond Well To Viagra

Researchers at the University of Pennsylvania School of Medicine say preliminary results of a small study show promise in improving erectile dysfunction (ED) in men who had shown minimal reaction to Viagra. The study results are published in the March issue of the "Journal of Sexual Medicine."

Erectile dysfunction is often a sign of a more severe vascular problem that involves abnormalities in the lining of the blood vessels. And often, endothelial dysfunction is an underlying problem for ED - it can be one of the first signs of atherosclerosis, a build-up of plaque and blockages in the arteries.

"It's already known that there is a connection between erectile dysfunction and coronary disease. The risk factors are the same for both, and thus, ED can be a marker for coronary disease," explains lead author Howard Herrmann, MD, Professor of Medicine and Director of the Interventional Cardiology and Cardiac Catheterization Laboratories at the Hospital of the University of Pennsylvania. "Normal erections are caused when nitric oxide is made, but with endothelial dysfunction, the body doesn't make enough of it, causing the erectile dysfunction. Normally, Viagra prevents the breakdown of the little nitric oxide that is there, so that there is enough of it for an erection to occur."

However, about 10-30 % of men are classified as "Viagra non-responders" - in these men, Viagra did not significantly help their erectile dysfunction. So in a small, double blind, randomized, placebo-controlled study at Penn, Herrmann looked at a dozen patients with ED who had not responded well to Viagra. He gave them either a high-dose Lipitor or a placebo. He then rechallenged them with Viagra and asked if the ED had improved.

"There did seem to be some improvement for those who received Lipitor versus the placebo," said Herrmann. "We theorized that if you could make the edothelium healthier through the use of statins — so that there is more nitric oxide available — you would improve the endothelial dysfunction and Viagra would work better for the patient."

And there are other potential benefits too. Stan Schwartz, MD, Director of the Diabetes Disease Management program at Penn and co-author, states, "Patients with Diabetes, both Type 1 and Type 2, are plagued with complications of the diabetic state that involve endothelial dysfunction. This research points us in a direction that says any drug class that improves endothelial dysfunction may also be beneficial to patients with diabetes."

Additionally, Emile Mohler, MD, Director of Vascular Medicine at Penn and co-author, cautions, "ED is a sign that cholesterol plaque may be present in the heart, neck or leg arteries. Men with ED should be evaluated for vascular disease."

"These preliminary results show promise," adds Herrmann. "They support the hypothesis that erectile dysfunction may be one sign of a generalized vascular disorder characterized by endothelial dysfunction and that statin drugs may improve the endothelial dysfunction, even before altering the lipid profile. But the results are preliminary and warrant further testing in a larger clinical trial," he cautions.

It should be noted that beyond endothelial dysfunction, there are other reasons Viagra may not work well for someone.

The results of this study were published in the March 2006 issue of the "Journal of Sexual Medicine." Members can access the journal on-line at: <http://jsm.issir.org>. The article is titled, "Can Atorvastatin Improve the Response to Sildenafil in Men with Erectile Dysfunction Not Initially Responsive to Sildenafil? Hypothesis and Pilot Trial Results."

This study was supported by an unrestricted medical center grant from Pfizer.

Drug wars over potency pill

Drug wars over potency pill

The Advertising Standards Agency is warning against a flock of companies trying to cash in on the Viagra craze.

The ASA says many firms are trying to jump on the Viagra bandwagon by advertising impotence 'cures' with names which are suspiciously like Viagra.

One, for a herbal treatment called Vigorex, actually uses the words: "Finally available in the UK. The potency pill that swept America".

It says the pill will give men "sexual powers beyond their wildest dreams" and should be snapped up before the "sheer frenzy" which will occur when it is officially launched in the UK.

The ASA is investigating Vigorex on the basis that it is trying to pass off as Viagra, the pill which is claimed to 'cure' impotency and give middle aged men the libido of a 20-year-old.

Herbal remedies

Viagra, manufactured by US company Pfizer, is expected to get the go-ahead for European sales this month, despite reports of over 100 deaths worldwide linked to it.

The drug acts by narrowing the blood vessels supplying the penis, causing an erection.

Most of the fake Viagra drugs are herbal remedies, containing Yohimbe bark, described as a natural aphrodisiac.

Many are marketed on the Internet, although some are also being advertised in magazines and newspapers.

Vigorex has its own Website where it is described as a strawberry-flavoured erection lotion.

Injunction

Other herbal remedies with names similar to Viagra include Vaegra, a vitamin and herbal supplement, and Viagro, another herbal remedy.

Legal action was taken against both. The US Federal Trade Commission won a temporary ban on Vaegra last month.

Some herbal remedies charge as much as the real Viagra. Experts claim they have not been subjected to any rigorous testing and claims about their effectiveness are dubious.

A UK television documentary revealed that the UK Counterfeit Intelligence Service is investigating several impotence 'cures', some of which use some of Viagra's ingredients.

Many are reportedly being manufactured in Thailand and India.

Other herbal cures, advertising themselves on the internet as "natural alternatives" to Viagra include Milagro, also made from Yohimbe bark, and Biogra.

The makers of Biogra claim people have flocked to it after concerns have been raised about the safety effects of Viagra.

Patterns of Use of Sildenafil Among Commercially Insured Adults in the United States: 1998-2002

Sildenafil is increasingly organism marketed to younger healthcare consumers.
The aim of this domain was to salience sildenafil use in commercially insured, person beneficiaries.
Yearly ambulatory medicine claims data from 1998 to 2002, for a nationwide, random example of over 5 zillion life-years of commercially insured adults (aged >/=18 y), were examined retrospectively.
The boilers suit figure of viagra use increased from 0.8% (1998) to 1.4% (2002), an 84% growth.
While the vegetation in use slowed in older males, use became more pronounced in younger males and females and decreased in older females.
The fastest ontogenesis piece of users was found to be males aged 18-45 y.
The proportionality of users who had two or more claims for a medicament that is suspected of inducing erectile dysfunction (ED) and/or a writing implement for a suspected ED-inducing disease decreased over the musical composition punctuation mark.
Our findings suggest that use may alteration among younger male and beast patients and those without an underlying etiologic rational motive for use.View

Sexual dysfunctions are marked by alteration in sexual arousal and the psychophysiological alterations associated with sexual style. Both sexes education sexual dysfunction; however, females (43%) are estimated to be at a higher risk than males (31%). Little investigation on the epidemiology and management of sexual dysfunction has been focused on females, perhaps due to the multicausal and multidimensional aspects of this physiological state in females. Conversely, there has been substantial problem solving performed on sexual dysfunction, particularly erectile dysfunction (ED), epidemiology, and intervention in males.

ED is an age-related term that can be associated with status information such as vascular disease, diabetes mellitus, impression, prostate disease, renal natural event, Parkinson’s disease and spinal cord accidental injury. The causes of ED can be organic, psychogenic, and/or iatrogenic. Regardless of suit, intracavernosal/transurethral prostaglandin E1 injections, oral medications, surgical operation, and space bottleneck devices are available as treatments.
Understandably, patients have demonstrated a orientation for oral therapies.

In 1998, viagra (Viagra®) became the first-class honours degree oral quality factor to receive mercantilism liking from the United States (US) Food and Drug Social control for the attention of sexual dysfunction in males. During clinical trials, viagra was found to be effective in relieving symptoms of ED in approximately 70% of subjects. Initial studies found viagra to provide results similar to medicinal drug for the intervention of sexual dysfunction in postmenopausal women, but indicated improvements in sexual software program in premenopausal women.

With a direct to consumer advertizing (DTCA) operation, sildenafil has brought the apprehension and handling of ED to the front end of populace consciousness. Originally, sildenafil DTCA in the US was targeted to older males (eg using Bob Dole as spokesperson, graphic art ad featuring gray-haired male dancing with gray-haired female), but it has been increasingly marketed to younger consumers (eg ballgame person Rafael Palmeiro as a spokesperson, sponsoring Concern, Wind, and Fire concert tour). Already concerned with the encroachment viagra has had on their chemist’s shop budgets, wellbeing plan sponsors now face the mortal of increased use among a younger procreation of ED patients.
In plus, mercantilism support of other infertility products (eg vardenafil, tadalafil) is forthcoming.
Message will likely increment use of oral impotency agents classwise.

viagra use is not without risks owing to its vasodilatory properties.
Judiciousness should be excercised in patients with one or more risk factors for cardiovascular or cerebrovascular disease, as cardiovascular events related to viagra include myocardial infarction, cardiac capture, inflammatory disease, ventricular tachycardia, hypertension, and other cardiac symptoms. Concomitant use with organic nitrates (eg glyceryl trinitrate, isosorbide dinitrate) has resulted in cardiac deaths, possibly due to cheap sildenafil citrate potentiating the nitrate’s hypotensive effects.

Few, if any, nationwide studies profiling sildenafil use are available.
Little is known about the characteristics of sildenafil users and prescribers and the use of sildenafil for underlying etiologic reasons.
In suburbia, there is a scarcity of message on the belief of messaging on sildenafil use, whether through DTCA of viagra to younger males or reports of cardiac deaths related to sildenafil use.
Thus, the goal of this opus was to saliency sildenafil use in a random, nationwide illustration of commercially insured, somebody beneficiaries from 1998 to 2002.
