The objective of this study was to analyse the market share of generic vs originator selective serotonin re-uptake inhibitors (SSRIs), and also compare market share of different SSRIs in the private health care sector in South Africa, over a period of 4 years.
This was a retrospective, descriptive study that measured generic market volume as a percentage of the total private SSRI market volume. Retail private sector sales data for six SSRIs available in the private sector in South Africa was evaluated. Sales data were obtained from various stages in the pharmaceutical supply chain, June 2009 - May 2013.
Generics constituted 86% and originators 14% of the private sector market volume of SSRIs. The share of the market volume of generic medicines increased by 29.93% over this 4-year period, while an overall increase of 27.86% in the ratio of generics to originators was observed.
In line with policies, generic SSRIs hold a larger volume of the market in the private sector in South Africa.
本研究的目的是分析通用型与原研型选择性5-羟色胺再摄取抑制剂（SSRI）的市场份额，并比较南非私立医疗保健部门中不同SSRI在4年期间的市场份额。
这是一项回顾性描述性研究，以通用型市场销量占私立SSRI总市场销量的百分比来衡量。对南非私立部门中可用的六种SSRI的零售私营部门销售数据进行了评估。销售数据来自2009年6月至2013年5月药品供应链的各个阶段。
通用型药物占私立部门SSRI市场销量的86%，原研型占14%。在这4年期间，通用型药物的市场销量份额增长了29.93%，同时通用型与原研型药物的比例总体增长了27.86%。
与政策一致，通用型SSRI在南非私立部门占据更大的市场份额。
