Ibuprofen is used

• For the treatment of sign and symptoms of rheumatoid arthritis, ankylosing spondylitis, osteoarthritis and other non-rheumatoid arthropathies,
• For the treatment of non-articular rheumatic conditions, such as frozen shoulder, bursitis, tendinitis, tenosynovitis and low back pain,

Phenylephrine is an alpha-1 adrenergic agonist used in the management of hypotension, generally in the surgical setting associated with the use of anesthetics.

Phenylephrine injections are indicated to treat hypotension caused by shock or anesthesia, an ophthalmic formulation is indicated to dilate pupils and induce vasoconstriction, an intranasal formulation is used to treat congestion, and a topical formulation is used to treat hemorrhoids. Off-label uses include situations that require local blood flow restriction such as the treatment of priapism.

How Nurofen Sinus Pain Relief works

The exact mechanism of action of ibuprofen is unknown. However, ibuprofen is considered an NSAID and thus it is a non-selective inhibitor of cyclooxygenase, which is an enzyme involved in prostaglandin (mediators of pain and fever) and thromboxane (stimulators of blood clotting) synthesis via the arachidonic acid pathway.

Ibuprofen is a non-selective COX inhibitor and hence, it inhibits the activity of both COX-1 and COX-2. The inhibition of COX-2 activity decreases the synthesis of prostaglandins involved in mediating inflammation, pain, fever, and swelling while the inhibition of COX-1 is thought to cause some of the side effects of ibuprofen including GI ulceration.

Phenylephrine is an alpha-1 adrenergic agonist that mediates vasoconstriction and mydriasis depending on the route and location of administration. Systemic exposure to phenylephrine also leads to agonism of alpha-1 adrenergic receptors, raising systolic and diastolic pressure as well as peripheral vascular resistance. Increased blood pressure stimulates the vagus nerve, causing reflex bradycardia.

Dosage

Nurofen Sinus Pain Relief dosage

Oral Administrations-

For Children:

• 20 mg per kg body weight daily in divided doses. In children weighing less than 30 kg the total daily dosage should not exceed 500 mg. If gastrointestinal disturbances occur Ibuprofenshould be given with food or milk.
• 1-2 years: 1/2 tea spoonful (2.5 ml) 3-4 times daily;
• 3-7 years: 1 tea spoonful (5 ml) 3-4 times daily;
• 8-12 years: 2 tea spoonful (10 ml) 3-4 times daily. Ibuprofenis not recommended for children under 1 year.

For adult:

• For arthritic pain: The dosage range is from 0.9 to 2.4 g per day. The usual dose is 400 mg, 3-4 times per day, preferably after food. The dose may be raised to a maximum of 2.4 g daily depending on the severity of symptom at the time of initiating drug therapy or as patients fail to respond. After a satisfactory response has been achieved the patients dose should be reviewed and adjusted as required and tapered gradually.
• For mild to moderate pain: 400 mg 6 hourly or as demanded by the condition.
• For dysmenorrhoea: 400 mg every 4 hours or as demanded by the condition.

Topical Administrations-

Pain and inflammation associated with musculoskeletal and joint disorder: As 5% cream, foam, gel, spray soln or 10% gel: Apply onto affected area.

Side Effects

Usually Ibuprofen has a low incidence of side effects. The most frequent side effects are gastrointestinal disturbances. Peptic ulceration and gastrointestinal bleeding have occasionally been reported. Other side effects include headache, dizziness, nervousness, skin rash, pruritus, drowsiness, insomnia, blurred vision and other ocular reactions, hypersensitivity reaction, abnormal liver function test, impairment of renal function, agranulocytosis and thrombocytopenia.

Toxicity

The symptoms of overdose are presented in individuals that consumed more than 99 mg/kg. Most common symptoms of overdose are abdominal pain, nausea, vomiting, lethargy, vertigo, drowsiness (somnolence), dizziness and insomnia. Other symptoms of overdose include headache, loss of consciousness, tinnitus, CNS depression, convulsions and seizures. May rarely cause metabolic acidosis, abnormal hepatic function, hyperkalemia, renal failure, dyspnea, respiratory depression, coma, acute renal failure, and apnea (primarily in very young pediatric patients).

The reported LD50 of ibuprofen is of 636 mg/kg in rat, 740 mg/kg in mouse and 495 mg/kg in guinea pig.

Patients experiencing and overdose may present with headache, hypertension, reflex bradycardia, tingling limbs, cardiac arrhythmias, and a feeling of fullness in the head. Overdose may be treated by supportive care and discontinuing phenylephrine, chronotropic medications, and vasodilators. Subcutaneous phentolamine may be used to treat tissue extravasation.

Precaution

Ibuprofen should be given with caution to patients with bleeding disorders, cardiovascular diseases, peptic ulceration or a history of such ulceration and in those who are receiving coumarin anticoagulants and in patients with renal or hepatic impairment.

Interaction

Increased risk of GI bleeding with warfarin, corticosteroids, SSRIs and aspirin. May reduce the natriuretic effects of diuretics. Reduced antihypertensive effect of ACE inhibitors and angiotensin II receptor antagonists. May increase toxicity of lithium and methotrexate. Increased nephrotoxicity with ciclosporin and tacrolimus.

Volume of Distribution

The apparent volume of distribution of ibuprofen is of 0.1 L/kg.

The volume of distribution of phenylephrine is 340L.

Elimination Route

It is very well absorbed orally and the peak serum concentration can be attained in 1 to 2 hours after extravascular administration. When ibuprofen is administered immediately after a meal there is a slight reduction in the absorption rate but there is no change in the extent of the absorption.

When orally administered, the absorption of ibuprofen in adults is very rapidly done in the upper GI tract. The average Cmax, Tmax and AUC ranges around 20 mcg/ml, 2 h and 70 mcg.h/ml. These parameters can vary depending on the enantiomer form, route, and dose of administration.

Phenylephrine is 38% orally bioavailable. Clinically significant systemic absorption of ophthalmic formulations is possible, especially at higher strengths and when the cornea is damaged.

Half Life

The serum half-life of ibuprofen is 1.2-2 hours. In patients with a compromised liver function, the half-life can be prolonged to 3.1-3.4 hours.

Intravenous phenylephrine has an effective half life of 5 minutes and an elimination half life of 2.5 hours.

Clearance

The clearance rate ranges between 3-13 L/h depending on the route of administration, enantiomer type and dosage.

Phenylephrine has an average clearance of 2100mL/min.

Elimination Route

Ibuprofen is rapidly metabolized and eliminated in the urine thus, this via accounts for more than 90% of the administered dose. It is completely eliminated in 24 hours after the last dose and almost all the administered dose goes through metabolism, representing about 99% of the eliminated dose. The biliary excretion of unchanged drug and active phase II metabolites represents 1% of the administered dose.

In summary, ibuprofen is excreted as metabolites or their conjugates. The elimination of ibuprofen is not impaired by old age or the presence of renal impairment.

86% of a dose of phenylephrine is recovered in the urine with 16% as the unmetabolized drug, 57% as the inactive meta-hydroxymendelic acid, and 8% as inactive sulfate conjugates.

Pregnancy & Breastfeeding use

Ibuprofen is not recommended during pregnancy or for use in nursing mothers.

Contraindication

Ibuprofen should not be given to patients with hypersensitivity to lbuprofen and to individuals who show nasal polyps, angioedema, bronchospastic reactivity to aspirin or other non-steroidal anti-inflammatory drug. Ibuprofen is contraindicated in patients with active or previous peptic ulceration & gastro-intestinal ulceration or bleeding.

Acute Overdose

Gastric lavage, correction of blood electrolytes (if necessary). There is no specific antidote for Ibuprofen

Storage Condition

Keep in a cool & dry place. Keep out of the reach of children.
