Drug combinations are used to minimize resistance in certain infections, for example tuberculosis.

The sulphonamides were the first drugs found to be effective in the treatment of systemic infections and although they do still have some specific uses, for example treatment of toxoplasma infections in patients with HIV, they are not much used nowadays because of bacterial resistance and the development of more effective drugs, which are less toxic.

Sometimes pulse doses of corticosteroids are used to suppress inflammation while longer term and slower acting DMARDs are being started. Corticosteroids suppress all phases of the inflammatory response, including the early swelling, redness and pain and the later stages seen in chronic inflammation.

The physiotherapist would then have full access to medical records and medication details. A physiotherapist working in rehabilitation of older patients is likely to find occasion to prescribe analgesics, anticoagulants, antibiotics (including for MRSA) antacids and laxatives. Management of long-term neurological conditions could mean wider prescribing. The benefits of extended prescribing apply to both patients and physiotherapists.

Hypoglycaemia can occur with any of these drugs and is particularly dangerous in the elderly. Gastrointestinal upsets and allergic skin rashes have been reported, as has bone marrow damage, which is rare but nevertheless severe. Biguanides do not affect insulin production but they do require some functioning β-cells to work.

Infections such as tuberculosis can spread extensively before they are discovered.

The conduction pathway of electrical activity goes from the SA node to the atrioventricular node between atria and ventricles, then down the septum between the two ventricles to the apex of the heart and finally round the ventricles themselves.

Apart from nitrous oxide, which is still widely used, earlier inhalation anaesthetics are no longer used. Ether is not suitable because it is explosive and irritant to the respiratory tract. Chloroform cannot be used because it is toxic to the liver. Inhalation anaesthetics currently in use are the volatile liquids halothane and more recently isoflurane, desflurane and sevoflurane and nitrous oxide gas.
