Sodium-glucose co-transporter 2 (SGLT2) inhibitors lower blood glucose by reducing the reabsorption of glucose in the kidney. They are a second-line therapy for type 2 diabetes. During clinical trials it was noticed that SGLT2 inhibitors had favourable effects on cardiovascular and renal disease. ⋯ However, a decline in the glomerular filtration rate may be seen at the start of treatment. As most experience with SGLT2 inhibitors is in diabetes, patients without diabetes need to be aware of why they are being prescribed these drugs. Some of the potential indications for SGLT2 inhibitors beyond diabetes are not yet approved by regulatory authorities.

Most of the benefit of asthma preventer inhalers is seen with low doses. However, many Australian patients are prescribed doses of inhaled corticosteroids that are higher than necessary to control their asthma. Prescribing unnecessarily high preventer doses increases the patient's risk of adverse effects. ⋯ Asthma guidelines recommend considering a step-down in preventer treatment after asthma has been well controlled for two to three months in adults and for six months in children. The step-down process should be individualised for each patient. Preventive therapy should not be stopped completely.

Drugs with anticholinergic effects are known to cause adverse effects such as dry mouth, constipation and urinary retention. In older people drugs with anticholinergic effects may contribute to cognitive decline and a loss of functional capacity. Many drugs that are not in the anticholinergic drug class also have anticholinergic effects. ⋯ This can assist decisions about continuing or stopping drugs with anticholinergic effects. Deprescribing drugs with anticholinergic effects has several potential benefits in older people. In addition to reversing adverse effects, deprescribing may prevent problems such as falls.

The goals of acute rheumatic fever therapy are to relieve symptoms, mitigate cardiac valve damage and eradicate streptococcal infection. Preventing future recurrences requires long-term secondary antibiotic prophylaxis and ongoing prevention of Streptococcus pyogenes (group A streptococcus) infections The recommended regimen for secondary prophylaxis comprises benzathine benzylpenicillin G intramuscular injections every four weeks. ⋯ Secondary antibiotic prophylaxis can reduce the long-term severity of rheumatic heart disease Patients with rheumatic heart disease, including those receiving benzathine benzylpenicillin G prophylaxis, should receive amoxicillin prophylaxis before undergoing high-risk dental or surgical procedures. If they have recently been treated with a course of penicillin or amoxicillin, or have immediate penicillin hypersensitivity, clindamycin is recommended.
