Description and composition of Medprofen
Table of Contents
Medprofen, a propionic acid derivative, is a traditional non-steroidal anti-inflammatory drug (NSAID). It contains Ibuprofen as its active ingredient. It also contains inactive ingredients in sufficient quantities.
Being an NSAID, it therefore has analgesic, anti-inflammatory and antipyretic activities. It acts primarily through non-selective, reversible inhibition of the cyclooxygenase enzymes COX-1 and COX-2. COX inhibition results in a marked reduction in prostaglandin synthesis. Furthermore, ibuprofen reversibly inhibits platelet aggregation.

- Mild to moderate pain and inflammation, pyrexia, headache.

The following are notable side effects of Ibuprofen.
- Gastro intestinal disturbances including nausea, diarrhoea, dyspepsia,
- Gastro intestinal ulceration and haemorrhage.
- Hypersensitivity reactions including rash, angioedema, bronchospasm.
- Headache, dizziness, nervousness, depression, drowsiness, insomnia, vertigo, tinnitus, photosensitivity, haematuria.
- Fluid retention (rarely precipitating congestive heart failure in elderly), raised blood pressure, renal failure.
- Rarely, hepatic damage, alveolitis, pulmonary eosinophilia, pancreatitis, visual disturbances, erythema multiforme (Stevens-Johnson syndrome), toxic epidermal necrolysis (Lyell’s syndrome), colitis, aseptic meningitis.
- Very rarely, exfoliative dermatitis, purpura
Always report serious side effects of any medicine to your healthcare provider or to an emergency department.
How to administer Medprofen
Medprofen is for oral use only. It can come in different dosage forms such as Syrup, capsules and tablets.
It may be administered with food to minimize gastro intestinal upset.
Sustained-release products should be swallowed whole with plenty of fluid and not chewed, broken, crushed or sucked on to avoid dose dumping, gastro intestinal discomfort and throat irritation.
Contraindications of Medprofen
- Hypersensitivity (including asthma, angioedema, urticaria or rhinitis) to acetylsalicylic acid or any other NSAIDs.
- Active peptic ulceration
- Hepatic or renal impairment.
- Preferably avoid in history of peptic ulceration.
- Cardiac disease
- Coagulation defects.
- Allergic disorders
- Anticoagulants: NSAIDs may enhance the effects of anticoagulants, such as warfarin.
- Antihypertensives and diuretics: NSAIDS may diminish the effect of these drugs. Diuretics can increase the risk of nephrotoxicity associated with NSAIDs.
- Corticosteroids, antiplatelet agents and SSRIS: Concurrent use may increase the risk of gastrointestinal bleeding.
- Cardiac glycosides: NSAIDs may exacerbate cardiac failure, reduce GFR and increase plasma glycoside levels.
- Aspirin: As with other NSAIDs, co-administration of Ibuprofen with Aspirin is not generally recommended because of the increased risk of adverse effects.
- Lithium: Concurrent use may lead to increased plasma levels of lithium.
- Methotrexate: Concurrent use may lead to increased plasma levels of methotrexate.
- Cyclosporin: Increased risk of nephrotoxicity.
- Zidovudine: Increased risk of haematological toxicity when NSAIDs are given with zidovudine.
