The Pharmacy Treatment Alliance will offer a Medicare-approved drug discount card beginning May 3, when Medicare beneficiaries will start trying to get the card. On June 1 Enrollees will begin receiving discounts on their prescription drugs. The Pharmacy Care Alliance estimates that the Medicare beneficiaries will be able to save just as much as 20 % on brand and 40 % on generic drugs by using its Medicare-approved drug price cut card. Medicare-approved drug discount cards are made to help beneficiaries with prescription medication costs until the complete federal prescription medication coverage – Medicare Component D – takes effect in January 2006.. 76 % of Medicare beneficiaries believe the Medicare medication discount cards are a good idea According to a survey commissioned by the Pharmacy Care Alliance, a large majority-76 %-of Medicare beneficiaries with out prescription drug protection polled believe the Medicare drug discount cards certainly are a good idea and can help them spend less.The reason behind the non-efficacy of the medication is not yet known. A study last year using it in homosexual men discovered that it reduced attacks by 44 %. Another study in which a similar drug was used in a vaginal gel decreased the HIV disease rate in women by 39 %. It is designed to be used after infection in conjunction with other antiretroviral medicines. Two other research are underway in sub-Saharan Africa to check the compounds in tablet and gel form for HIV prevention in heterosexual women and men. If successful it would be an inexpensive and easy method for AIDS prevention.
