WHAT ABOUT GENERIC ALPHAGAN?
Over the years, there has been quite a degree of evolution in the class
of drugs known as alpha agonists. Epinephrine related products were largely
replaced with Propine and later by a drug called Apraclonidine. In 1996,
Allergan released a drug called Alphagan (brimonidine .2%). Although this
drug was not typically used as the first treatment for glaucoma, it was
a very effective drug in some patients. One of its limitations was that
it caused allergy in a significant number of patients. In 2001, Allergan
released an improved version under the name of Alphagan P (0.15%). This
new form was reported to cause less redness and allergy. After several
months, production of Alphagan was halted as the majority of the patients
were switched from Alphagan to Alphagan P. Recently, the patent protection
for Alphagan expired, and several companies have begun making a generic
version of Alphagan (Brimonidine). Because Brimonidine has a different
preservative and different strength than Alphagan P, these drugs are not
strictly considered generic equivalents, and substitutions may not be
made by the pharmacist without permission of the physician.
If patients desire brimonidine .2% (generic Alphagan), we are happy to
write them a prescription and they can compare the price of the generic
product to that of the brand name Alphagan P, and they can determine for
themselves whether there is a problem with redness or allergy. Only the
eye doctor can help them assess whether there is a difference in the effectiveness
of the two drugs.
In effect, there is a generic Alphagan (brimonidine .2%), but there is
no longer a brand name Alphagan being sold. There is a brand name Alphagan
P in the pharmacies, but no generic Alphagan P at this point.
