In Finland, mandatory generic drug substitution was adopted in 2003 [1]. This is overseen by pharmaceutical staff who give advice to patients and decide which drug products they should receive. A recent study by Ranio et al. assessed the content of patient counselling about interchangeable medicines and generics substitution in Finnish community pharmacies [2].

A link between socioeconomic status and the prescription of brand-name drugs in the US, has been revealed by a team of researchers based at Brown University [1].

Modelling of the cost savings from the use of generic Gleevec (imatinib) in the US finds that US payers saved US$2.5 billion in years 1 and 2 following patent expiry. Projected savings in years 3 to 5 exceed US$12 billion, even without step-edit formulary management [1].

Since the enactment of Hatch-Waxman Act in 1984, use of generics has grown substantially in the US. Generics now account for nearly nine out of 10 prescriptions and are considered a cost-containment solution for escalating healthcare expenditures [1]. However, several factors may influence the use of generics including, but not limited to, the perception of the safety and effectiveness of these products [2]. The US Food and Drug Administration’s (FDA) standard of bioequivalence requires similar pharmacokinetic (PK) profiles of generic versus reference drug products with the assumption of similar pharmacodynamic (PD) effect. However, several instances related to generics substitution and treatment failures have led to concern particularly for drugs with narrow therapeutic indices and in therapeutic areas with severe effectiveness and safety outcomes.

The labels for established generics and their originators differ. Especially when it comes to safety messaging, these differences could have a fatal or life-threatening impact on patients, according to researchers from Switzerland [1].

Generics offer less expensive alternatives to brand-name drugs. However, they must be accepted by patients to increase uptake and reduce healthcare cost. Finland adopted generics substitution in 2003. Then, in 2009, this was supplemented with a reference price system. A recent survey [1] has shown that the price of medicine is key for Finnish pharmacy customers.

The cost of prescription drugs is a concern in the US. Drug prices typically decline once a generic drug is approved due to market competition. However, in recent years generics prices have risen and there have been shortages. The US Food and Drug Administration (FDA) has taken action to reduce prices and increase generics competition. It is hoped that this will increase access to medicines across the country.

Healthcare budgets in the US are under strain and the cost of prescription drugs is a continuous concern. Generic drugs offer cheaper alternatives to brand-name products due to competition. However, in recent years generics prices have risen in the US and there have been shortages of products.

Poor management of the drug inventory in hospitals can be caused by stagnant and stock-out conditions, which might lead to economic loss. In order to investigate this phenomenon, researchers from Indonesia compared the economic loss between generics and patented drugs in stagnant and stock-out conditions at the Surabaya Islamic Hospital [1].

Patients with lower incomes are more likely to use generic drugs, finds a literature review from Auburn University, Alabama, USA [1].
