British National Formulary (BNF) Guidelines for Ibuprofen: A Comprehensive Overview

The British National Formulary (BNF) is a widely respected pharmaceutical reference book that provides healthcare professionals with essential information on prescribing medications. Its guidelines for ibuprofen offer a detailed and authoritative perspective on the appropriate use, dosage, and considerations for this commonly used non-steroidal anti-inflammatory drug (NSAID). Understanding the BNF's recommendations for ibuprofen is crucial for healthcare providers and can be informative for patients seeking to understand their medication regimens.

According to the BNF, ibuprofen is indicated for the management of mild to moderate pain, inflammatory conditions, and fever. It's classified as an NSAID and works by inhibiting prostaglandin synthesis, which is responsible for pain and inflammation in the body. The BNF outlines several specific indications for ibuprofen use, including osteoarthritis, rheumatoid arthritis, soft-tissue disorders, back pain, dental pain, postoperative pain, dysmenorrhoea, headache, and migraine.

The BNF provides detailed dosage guidelines for ibuprofen, which vary depending on the patient's age, the condition being treated, and the route of administration. For adults, the standard oral dose for pain and inflammation is 200-400 mg, 3-4 times daily, with a maximum daily dose of 2.4 g. However, for certain conditions like rheumatoid arthritis, the BNF notes that higher doses up to 3.2 g daily may be used under medical supervision.

For children, the BNF recommends weight-based dosing. The standard dose is 20-30 mg/kg daily in divided doses. For example, for a child aged 1-2 years, the recommended dose is 50 mg 3-4 times daily, while for a child aged 7-9 years, it's 200 mg 3-4 times daily. The BNF emphasizes the importance of not exceeding the recommended dose and duration of treatment for children.

The BNF also provides guidance on different formulations of ibuprofen. Besides oral tablets and capsules, it discusses liquid formulations, which are particularly useful for children and adults who have difficulty swallowing tablets. Topical preparations of ibuprofen are also mentioned, with recommendations for their use in localized pain and inflammation.

An important aspect of the BNF's guidance on ibuprofen is its emphasis on potential side effects and contraindications. It warns that NSAIDs, including ibuprofen, can cause gastrointestinal bleeding and ulceration, particularly in elderly patients or those with a history of peptic ulcers. The BNF advises that the lowest effective dose should be used for the shortest duration necessary to control symptoms.

The BNF also highlights specific contraindications for ibuprofen use. These include severe heart failure, active gastrointestinal bleeding or ulceration, and severe liver or kidney impairment. It advises caution in patients with a history of gastrointestinal disorders, cardiovascular disease, or hypertension, as ibuprofen can exacerbate these conditions.

Interactions with other medications are thoroughly detailed in the BNF's ibuprofen monograph. It notes that ibuprofen can interact with several common medications, including warfarin (increasing the risk of bleeding), lithium (potentially increasing lithium levels), and certain antihypertensive drugs (potentially reducing their effectiveness). The BNF advises healthcare professionals to carefully consider these interactions when prescribing ibuprofen.

Pregnancy and breastfeeding considerations are also addressed in the BNF's guidance. It advises against the use of ibuprofen during the third trimester of pregnancy due to the risk of premature closure of the ductus arteriosus and possible persistent pulmonary hypertension in the newborn. For breastfeeding mothers, the BNF notes that ibuprofen is present in breast milk but in amounts too small to be harmful to the infant.
