Pharmaceutical Benefits Scheme
Certain medications listed on the PBS are available only for specific therapeutic indications or to patients meeting specific criteria where the PBAC has deemed that the cost-benefit analysis is favourable only in those indications/patients. These are noted as "restricted benefits" on the Schedule. Medicare Australia places the onus of policing restricted benefits on the prescribers themselves and the pharmacists dispensing (unless the listing is also 'Authority Required'). For example, the COX-2 inhibitor celecoxib is listed on the PBS as a restricted benefit for the symptomatic treatment of osteoarthritis and rheumatoid arthritis. Prescribers using celecoxib for other indications are expected to indicate "non-PBS" on the prescription, and/or the pharmacist dispensing the celecoxib should charge the patient the full cost.
Colchicine
Oral colchicine had been used for many years as an unapproved drug with no FDA-approved prescribing information, dosage recommendations, or drug interaction warnings. On July 30, 2009 the FDA approved colchicine as a monotherapy for the treatment of three different indications (familial Mediterranean fever, acute gout flares, and for the prophylaxis of gout flares), and gave URL Pharma a three-year marketing exclusivity agreement in exchange for URL Pharma doing 17 new studies and investing $100 million into the product, of which $45 million went to the FDA for the application fee. URL Pharma raised the price from $0.09 per tablet to $4.85, and the FDA removed the older unapproved colchicine from the market in October 2010, both in oral and intravenous forms, but gave pharmacies the opportunity to buy up the older unapproved colchicine. Colchicine in combination with probenecid has been FDA-approved prior to 1982.
