Sir: The discovery of Sovaldi, a medicine that is helpful to cure Hepatitis C that infects 170 to 200 million people around the globe, is good news. In Pakistan there are 10 to 15 million people suffering from this deadly disease. However, the availability of the drug has been made difficult. In Pakistan, only one company is allowed to sell it, that too in limited quantities. In Rawalpindi, only one chemist is authorised to sell it on a prescription from a private clinic that costs Rs 2,500 per patient. Sovaldi has 90 percent rate of cure and one bottle costs Rs 32,000, which contains the dosage for one month. This is too expensive for poor people. The government needs to make Sovaldi available at hospitals and medical stores at a relatively cheaper price.
