Medical Letter, a nonprofit organization founded in 1958, has released a Palm OS version of its Treatment Guidelines. The publication provides unbiased drug prescribing recommendations to physicians and other healthcare professionals. These guidelines are also available in print and online.

According to Medical Letter, each month, Treatment Guidelines from The Medical Letter provides prescribing and formulary recommendations for diseases such as diabetes, asthma, osteoporosis, hypertension, rheumatoid arthritis, heart failure, cancer, high cholesterol levels, epilepsy, pain, depression, as well as treatment of bacterial, fungal and viral infections. There are also PDA retail price comparison and dosage charts.

"The unique editorial process used to produce Treatment Guidelines results in prescribing recommendations that are free of pharmaceutical influence," said deputy editor Gianna Zuccotti, M.D., M.P.H. "Now these trusted recommendations can be easily accessed by physicians through their PDA."

In addition to its newsletters, Medical Letter also publishes handbooks and software on topics such as adverse drug interactions and antimicrobial therapy.
