                     Therapeutics Initiative, based at the University of British Columbia,

                     provides up-to-date, evidence-based, practical information on drug

                    therapy. One feature is the Therapeutics Letter – a short publication

                  that targets problematic drug issues. Another feature is the Podcasts –

                        case-based education sessions (20-30 minutes) that can be

                   downloaded to your MP3 player. Registration is free at www.ti.ubc.ca

**New Canadian Hypertension Guidelines 2009**

      CHEP is the Canadian Hypertension Education Program

      CHEP provides recommendations for the diagnosis and treatment of

       hypertension in Canada

                                   What’s New?

   CHEP Theme for 2009: Hypertension in the diabetic patient

      80% of diabetics die of CVD and a recent survey showed that more

       than 2/3 of diabetics in Canada had uncontrolled BP

      CHEP recommends that all diabetics be screened and aggressively

       treated for hypertension with a combo of lifestyle and pharmacotherapy

       in order to control BP to <130/80mmHg

   Combination Therapy with ACE Inhibitors and ARBs

      CHEP now does NOT recommend the use of the combo of an ACE

       inhibitor and ARB in patients with:

        1) Uncomplicated Hypertension

        2) Ischemic heart disease in the absence of heart failure

        3) Non proteinuric chronic kidney disease

        4) Diabetes without microalbuminuria

      This is based on new studies that suggest this combo leads to an

       increased risk of adverse effects (hyperkalemia, hypotension, renal

       impairment) without any added benefit in these pt groups

      The only pts who should be considered for this combo (as there is still

       evidence for benefit) are pts with advanced heart failure or
               proteinuric nephropathy.


            CHEP specifically recommends that age not be used as a factor in

               prescribing drugs for hypertension

              New studies show clear benefits of lowering BP in the elderly (>80

               years); therefore, treat these pts similarly to other pts.

              However, use caution with frail elderly pts (esp those with postural

               hypotension) as risks of treating may outweigh the benefits.

                                       Other Important Reminders

            CHEP continues to encourage home BP measurement

            Assess BP at all appropriate visits

            Assess and manage overall CV risk in hypertensive patients

            Lifestyle modification is the cornerstone for management

What’s the deal with the new Pantoprazole Magnesium (Tecta™)?

                                               Bottom Line
              Tecta™ (pantoprazole magnesium) is a new salt form of

               pantoprazole sodium (Pantoloc™ - which recently went generic)

              Tecta™ is more expensive than generic pantoprazole sodium,

               generic omeprazole and rabeprazole (Pariet™)

              Tecta™ is not currently on the provincial formulary

              There is no published information available that supports the drug

               company’s claims that Tecta™ it is clinically equivalent to
    Pantoloc™ (or other PPIs)

   Tecta™ (pantoprazole magnesium) is a new salt form of pantoprazole

    sodium (Pantoloc™) marketed by Nycomed Canada.

   Approved for sale in Canada in 2006

   Dose = 40mg once daily in the morning for most indications

   Similar treatment indications to other PPIs


   Tecta™ is not currently on Sask provincial formulary

   Cost comparison (obtained from a local pharmacy Mar 23, 2009):

                   1. Tecta™ 40mg x 30 tabs = $58.04

                   2. pantoprazole (generic) 40mg x 30 tabs = $53.84

                   3. omeprazole (generic) 20mg x 30 tabs = $44.93

                   4. rabeprazole (Pariet™) 20mg x 30 tabs = $38.66

                          Evidence – Tecta™ vs. Pantoloc™

   Tecta™ was shown have similar effects to Pantoloc™ on esophagitis

    healing rates in a one UNPUBLISHED RCT in 636 pts with GERD.

   Pharmacokinetic parameters (i.e., Cmax) are not equivalent between

    the two products

   There is no long term data on adverse effect or drug interaction

    differences between the two products.

         The Importance of Asthma / COPD Inhaler Technique

                      Poor inhaler technique is a very common problem

                      Improper technique leaves medication in the mouth and throat

                       instead of getting into the lungs where it is effective

                      To assess a patient’s inhaler technique, observe a demonstration by

                       the patient first, then offer suggestions for improvement

                      For examples of technique for an MDI without a spacer:




                      And an MDI with a spacer:





                      A Turbuhaler:



                      A diskus (called an accuhaler in the video)
