Record-breaking Viagra Claims 95% of Market May 14, 1998 4:25 PM NEWTOWN, Pa.--(BW HealthWire)--May 14, 1998--In its first month on the market, Viagra, Pfizer's impotence therapy, generated more new prescriptions than the company's popular calcium channel blocker, Norvasc, and Parke-Davis' cholesterol reducer, Lipitor, which Pfizer co-promotes.
Four Pfizer products were among the top 20 brand-name drugs dispensed in April.
According to Scott-Levin's Source Prescription Audit, 570,000 new prescriptions for Viagra were dispensed in April -- the most prescriptions ever for a drug in the United States during its first full month of availability.
To put this into perspective, Lipitor, which many labeled the most successful launch of all time, had only 26,000 new prescriptions in its first month. The Wyeth-Ayerst obesity medication Redux, another high-profile launch, had 149,000 new prescriptions during its first month.
In April, Viagra claimed 95% of new prescriptions in the erectile dysfunction market. Vivus' MUSE captured 4% of new prescriptions, while Pharmacia & Upjohn's Caverject had a 1% share of the market. Urologists wrote 41% of new Viagra prescriptions, while general and family practitioners accounted for 23%. Internists (21%), cardiologists (2%) and general surgeons (1%) rounded out the top five prescriber groups for Viagra.
More than 50% of Viagra prescriptions were paid for in cash, with the remainder reimbursed by third-party organizations. This is not surprising; managed care plans have adopted stringent guidelines for Viagra reimbursement. The product costs patients approximately $9.25 per day. Many insurers will only reimburse for Viagra if patients have a written statement from their physician indicating that they suffer from erectile dysfunction.
