Does there exist a cheap generic for Lexapro? Or another generic SSRI as good as Lexapro for general anxiety control? > Does there exist a cheap generic for Lexapro? > > Or another generic SSRI as good as Lexapro for general > anxiety control? Although someone marked this post as junk, it does not seem like a junk post. True, it is full of spelling and grammatical error. While that would turn me off or put me to sleep, it does not seem like serious junk. Bill >Does there exist a cheap generic for Lexapro? > >Or another generic SSRI as good as Lexapro for general >anxiety control? Lexapro, chemical name escitalopram isn't available as a generic. Citalopram brand name Celexa, is a very similar less expensive generic alternative.  Signaturemred > Lexapro, chemical name escitalopram isn't available as a generic. > Citalopram brand name Celexa, is a very similar less expensive generic > alternative. Although it is not my expertise, I do know that Citalopram is a mixture of two enantiomers. That is a 50-50 mixture of what is Lexapro and its mirror image molecule. Lexapro. Only the Lexapro (the left-handed molecule) is active. The right-handed version present. If all is well, there will be no harm from this right-handed molecule.

People knowledgeable, physicians, pharmacists can steer patients to considerably less expense, very similar alternatives.

I would think that in most cases, the technology to extract a pure enantiomer is well known to a competent chemical practitioner and does not require the innovation deserving of a patent. The same comment applies to time release medications. What is the inventive spark to that?

Its not really a novel compound. Probably need a patent attorney to explain. The PBM's are on to this practice, they almost never pay for newer items, without prior authorization or tiered co-pays. The drug manufactures are trying to protect bottom line, because low numbers of new drugs currently in pipeline. Signaturemred > Legal basis, not sure.

As much as I detest parasitical pharmaceutical companies, just because a compound is known does not preclude patents for its manufacture. For example, ammonia was a well known compound before the Haber process for manufacturing it was developed. Haber deserved to be considered an inventor. My argument is that many of the processes used for manufacture afre likely to be what any competent chemical engineer could do one he or possibly she, knows of similar previously known manufacture.

Signaturemred >Does there exist a cheap generic for Lexapro? > >Or another generic SSRI as good as Lexapro for general >anxiety control? Yes there is generic Lexapro (Escitalopram) available for good quality and cheap price. You can find at http://www.internationaldrugmart.com/lexapro.html
