WHAT do acarbose, nizatidine and The Ashes have in common? Not much — but they do all appear in this article.
I recently attended a diabetes update and was bedazzled by the advances in diagnosis, classification and treatments of this common disease.
Regular readers of this column know that I am no disciple of medicine-by-protocol as it can be too restrictive, takes away clinical autonomy and lends itself to doctor substitution.
The AACE algorithms are a breath of fresh air because they offer clinicians flexibility and aren’t motivated by governmental factors like the Pharmaceutical Benefits Scheme. Doctors spend a whole lot of time studying a whole lot of stuff, and they should be allowed to use this knowledge in its entirety for the benefit of their patients.
Acarbose appears twice in the AACE algorithms; both for diabetes and prediabetes. I thought, “Wow! That’s a drug I have not used for 7–8 years!”
Attending clinical updates, it’s easy to get swept up in all that is new, forgetting all the old tried and trusted (and often cheaper) treatments. The recent MJA article on phenytoin as an antiarrhythmic is another fantastic example of this.
There are a number of reasons why drugs go in and out of fashion — drug companies promoting newer medications; clinical guidelines that can come from a variety of institutions; peer pressure from colleagues; and how often we revise our own knowledge.
So in the spirit of The Ashes, I present my First XI of “forgotten” drugs that I believe still have a role to play in practice:
I) Nizatidine: When a proton pump inhibitor fails or is contraindicated for a patient with peptic ulcer disease, H2-antagonists still have a role to play. Nizatidine also possesses pro-motility properties.
II) Sucralfate: Most of my registrars and medical students have never heard of it, but worth thinking about as a third or fourth line drug in peptic ulcer disease.
III) Imipramine: Oscar London, author of a book on how to be the world’s best doctor, reminds us to never give psychiatrists credit for starting a patient on a tricyclic antidepressant. This class of drugs is also handy for insomnia, enuresis, neuropathic pain and urinary incontinence.
IV) Moclobemide: How long since you’ve seen a depressed patient on this drug? About 15–20 years ago it was popular; then SSRIs (selective serotonin reuptake inhibitors), SNRIs (serotonin–norepinepherine reuptake inhibitors) and new antipsychotics came to town with all their marketing and swept it away. It is effective, safer than many other antidepressants in the elderly and has easy dosing.
V) Acarbose: This drug to treat type 2 diabetes seems to play a bigger role in the US than there, but is included in our team as “an option for improving glycaemic control”.
VI) Nitrofurantoin: Our wicket-keeper is a very safe pair of hands for urinary tract infection (UTI). So many UTIs remain sensitive to it but I know of hardly anyone who gives it a run these days. I’ve seen many an urologist use it as a prophylactic antibiotic at low dose.
VII) Ampicillin: We are constantly told about antibiotic stewardship, yet hospital doctors seem to always prescribe the latest and dearest antibiotics. This all-rounder (hence batting at number seven) still has many applications, not least respiratory tract infection.
VIII) Doxycycline: With broad antibiotic properties, this drug is a rural doctor’s best friend. It covers atypicals like Q-fever and leptospirosis, as well as being effective for respiratory tract, skin and genitourinary tract infections and as a malaria prophylaxis.
IX) Co-trimoxazole: My team is big on all-rounders and this sulfur drug is not only good for urinary tract infection, but also great for respiratory tract, atypicals and skin. The syrup for children does not need to be in the fridge, which is handy for many parents.
X) Cefaclor: A small number of children get a serum sickness-like adverse reaction with this drug so many have rejected it. But it’s still a very useful and mostly well tolerated antibiotic for many patients.
XI) Soluble aspirin: Patients can buy this cheaply at the supermarket and it often gets forgotten, yet has so many uses.
This list is my opinion and in no way intended to modify your prescribing habits. I hope it will stimulate you into thinking and talking to colleagues about some of your favourite older drugs.
And please feel free to add your comments below about my XI. There may be some you want to drop from the team and add your own better performers.
I am confident my First XI performs better than our crumbling Aussie cricketers.
