Generic versions of the anti-hypertensive irbesartan are equally effective as their branded counterparts, finds a phase IV study conducted in Korea.

Adherence to generic versus brand-name statins and associated clinical and economic outcomes

Despite evidence supporting the efficacy of statins for the treatment and prevention of cardiovascular disease, a lack of adherence to statin treatment continues to be a major problem. Sicras-Mainar and colleagues investigated real-world treatment persistence and medical possession for generic versus brand-name statins used in routine clinical practice, and assessed associated clinical and economic outcomes [1].

Mixed beliefs about generics among patients in a Malaysian hospital

The Malaysian Government is heavily subsidizing public healthcare expenditure in order to provide access to health care for all citizens. In 2017, total healthcare expenditure in the country was approximately 9.4% of the annual budget. In order to overcome the increasing cost of health care, the government has implemented a National Generic Medicine Policy in 2006 to promote healthier competition in medicine pricing and to make medicines more affordable to the general public. After 10 years of policy implementation, authors from the Ministry of Health Malaysia assess patients' beliefs about generics.

Market evolution of new drug formulations

Brand-name drug manufacturers sometimes create modified versions of their approved drugs which can include new strengths, dosage forms, or delivery routes. This product modification can meaningfully increase patient treatment options; however, some cases have come under scrutiny as they do not offer any clear therapeutic advantages. This second practice is a form of ‘product hopping’, a method used by manufacturers to prolong revenue streams related to market exclusivity. Complementary strategies such as product discontinuation can augment the impact of product hopping.

Factors associated with increased side effects and lower perceived efficacy when switching to a generic

In 2017, the New Zealand Pharmaceutical Management Agency (PHARMAC) changed the funded version of the antidepressant venlafaxine from Efexor XR (the branded originator) or Arrow-Venlafaxine XR (a generic version) to a new generic, Enlafax XR. MacKrill and Petrie examined differences in preferences and perceptions between patients switched from the originator branded venlafaxine to the new generic, and those switched from the old generic version [1]. Specifically, they investigated the factors associated with preference for branded medicines, side effects reported following switching and efficacy ratings of the new generic.

Escalating prices of generic drugs in the US

Generic prescription drug prices have been escalating rapidly in the US. In 2014, generic drug prices increased by 38% on average. Public outcry has led to a flurry of legislative proposals, and two federal bills were introduced in 2017 to improve price transparency and identify drugs exhibiting outlier ‘price spikes’, however, both remain unenacted. In the first three months of 2018, 53 drug pricing transparency bills were initiated in 23 state legislatures.
