The variety of the LMIC was guided by the availability of knowledge from the retail sector in the a few geographical locations. Even although this is not a representative sample of nations around the world in every single region, the countries picked are important pharmaceutical marketplaces in phrases of their price in the respective locations.

For oral solids 1 SU is one particular pill or capsule. For oral liquids, a single SU is 5ml. Our investigation focuses on market share expressed as proportion of retail market place quantity. The Described Daily Dose (DDD) which is the standard approach when finding out medicines utilization was not utilised as, (i)“Total generic market place share”: the percentage of overall yearly personal sector product sales quantity of branded generic medications plus unbranded generic medicines divided by the complete once-a-year medicines private sector product sales quantity (originator additionally certified in addition branded generic furthermore unbranded generic medicines). Overall generic marketplace share = (unbranded + branded generic medications)/(unbranded + branded generic + originator + accredited medicines). “Branded generic medications market place share”: the share of yearly personal sector sales volume of branded generic medications divided by overall medicines personal sector income quantity, as defined instantly earlier mentioned. (iii) “Unbranded generic medicines industry share”: the proportion of once-a-year personal sector income quantity of unbranded generic medications divided by overall medications private sector revenue quantity, as described earlier mentioned. (ii) We took as the “regional” market share the median price of the respective marketplace shares for all countries in a given location (LAC, Asia, MeSA) of the diverse categories (unbranded, branded generic, originator) in a offered year. Hence, for the LAC area, the median regional branded generic industry share is the median price of the branded generic industry share for the 10 distinct LAC international locations.

We utilised the United States as a comparator. By hunting at particular pharmaceutical substances for every group (originator, branded generic, unbranded generic) we had been able to figure out if the lessen in market place share of a specific originator pharmaceutical substance was accompanied by an improve in its counterpart unbranded and/or branded generic market place share (s). We employed the disaggregated data on yearly volumes of a total 5131 different pharmaceutical substances (molecules or mixtures of molecules) for the ten nations listed earlier mentioned for all several years from 2001 to 2011. For every single country, we calculated the variation in quantity market place share (as a % of the complete quantity of all prescribed drugs for all types (exceptional of the “Patent N/A” category) amongst 2001 and 2011. For originator pharmaceutical substances, we ranked them by this so-named ”delta originator” with the biggest negative delta first, and picked for additional analysis the prime ranked 30 in this list (hereafter called the “top thirty list”).
