A national survey of price and affordability of key essential medicines for children in Sri Lanka.

OBJECTIVE

To investigate the price and affordability of key essential medicines for children in Sri Lanka.

METHODS

This national survey investigated the prices and affordability of 25 key essential medicines for children in private sector pharmacies using the WHO/Health Action International (HAI) medicine price methodology. Data were collected from a representative sample of 48 private sector pharmacies selected from 8 Provinces using a multistage clustered approach. At each pharmacy prices of originator brand (OB) and lowest priced generics (LPG) of the selected medicines were collected. Medicine prices were compared with international reference prices to obtain a median price ratio (MPR). Income of the lowest paid unskilled government worker was used to establish the affordability.

RESULTS

The median MPR of retail prices to patients was 3.7 for OB (range 0.23-20) and 1.35 for LPG (range 0.05-3.75). MPR >5 was observed for OBs of 5 medicines: ceftriaxone injection, diazepam injection, mebendazole syrup, mebendazole chewable tablet and metronidazole tablet whereas MPR >2.5 was observed only for LPGs of 3 medicines: chlorphenamine syrup, clotrimazole topical cream, and paracetamol syrup. Mean percent difference in price between OB and LPG products was 365 % (range -21, 2343). Rational treatment for acute infections such as mild lower respiratory tract infections and acute gastroenteritis seems to be affordable but treatment for chronic illnesses requiring liquid or inhaled dosage forms were largely unaffordable.

CONCLUSIONS

Intervention is needed to improve the economic access to key essential medicines for children indicated in the treatment of chronic diseases.
