Corflam Cold Drops

Corflam Cold Drops is the drug manufactured with the combination of Paracetamol IP, Phenylephrine HCL IP, and Chlorpheniramine Maleate IP.

Paracetamol IP

Paracetamol is a medicine more commonly used over-the-counter analgesic (i.e. for pain reliever) and antipyretic (i.e. for fever reducer).

Chemistry of Paracetamol

Chemical Formula: C8H9NO2

Molecular Mass: 151.17 g/mol

Pharmacokinetics of Paracetamol

Absorption: Paracetamol is easily absorbed from the gastrointestinal tract with peak plasma concentrations occurring nearby 10 to 60 minutes after the oral administration.

Distribution: Paracetamol is distributed into most of the body tissues. Plasma protein binding is negligible at usual therapeutic doses but increases with increasing doses.

Elimination: Its elimination half-life varies between 1 and 3 hours.

Pharmacodynamics of Paracetamol

Paracetamol is a p-aminophenol derivative that exposes analgesic and antipyretic activity and it does not have anti-inflammatory activity.

Medical uses of Paracetamol

Paracetamol has the following medical uses:

  • Used to reduce fever in people of all ages
  • Used for the relief of pains associated with various parts of the body
  • Side Effects of Paracetamol

    Though, the side effects of Paracetamol are mild to non-existent but prolonged daily use may cause:

  • Upper gastrointestinal complications (i.e. stomach bleeding)
  • Kidney or liver damage
  • Occasionally, it causes skin rashes and hypersensitivity reactions.
  • Overdose of Paracetamol

    Though, signs and symptoms of Paracetamol toxicity initially might be absent or vague but if treatment of overdose has not been given then it can cause to liver failure and death within days.

    Caution of Paracetamol

    Paracetamol should be used with caution especially with the patients who have:

  • Impaired renal function
  • Impaired hepatic function
  • Phenylephrine HCl IP

    Phenylephrine is the derivative of Phenylephrine (HCl) and it is of Synthetic origin that belongs to Aminoethanol.

    Chemistry of Phenylephrine HCL IP

    Chemical Formula: C9H13NO2, HCl

    Molecular Mass: 203.70

    Physical Properties: White, odourless, and crystalline powder

    Solubility: Fully soluble in water

    Pharmacokinetics of Phenylephrine HCL IP

    The oral absorption of Phenylephrine (HCl) is about 73% ±2. The volume of distribution is about 340 litres. Presystemic metabolism is measured about 60% and metabolism is reported Hepatic. And, the renal excretion accounts for < 20 % and plasma half life is 2 to 3 hours.

    Phenylephrine is largely excreted through the kidneys and about 80% to 90% of the orally given dosage is eliminated within 48 hours.

    Pharmacodynamics Phenylephrine HCL IP

    Oral phenylephrine is comprehensively metabolised by monoamine oxidise, an enzyme which remains in the gastrointestinal tract and the liver. Therefore, in comparison to orally-taken pseudoephedrine, it has a reduced and variable bioavailability of merely up to 38 percent, and hence it is less effective as a nasal decongestant than pseudoephedrine.

    Medical uses of Phenylephrine HCL IP

    Phenylephrine Hydrochloride is an active pharmaceutical element and it is being used largely for the following drugs formulations:

    Oral Preparations:

  • Capsules
  • Tablets and film tablets
  • Syrups and other liquids
  • Granules and powder for liquid intake
  • Topical preparations:

  • Eye drops
  • Nose drops and sprays
  • Some other uses are:

  • Oral strips
  • Chewable tablets
  • Creams
  • Ointments
  • Gels
  • Ear drops
  • Ophthalmic inlays
  • Nebulizers
  • Side Effects of Phenylephrine HCL IP

    Phenylephrine (HCl) produces potentially serious side effects which include:

  • Bradycardia
  • Vomiting
  • Severe hypertension
  • Overdose of Phenylephrine HCL IP

    The signs and symptoms that caused because of the overdose of Phenylephrine (HCl) are:

  • Bradycardia
  • Rise in B.P.
  • Caution of Phenylephrine HCL IP

    Phenylephrine should be used with caution with the patients who have hyperthyroidism, bradycardia, and partial heart block. Besides, it should be used in large vein to shun necrosis and sloughing of surrounding tissues.

    Chlorpheniramine Maleate

    Chlorpheniramine (Maleate) also known as Chlorphenamine Maleate is a first-generation alkylamine antihistamine and generally used in the prevention of the symptoms of allergic conditions including rhinitis and urticaria.

    Chemistry of Chlorpheniramine Maleate

    Chemical Formula: C16H19ClN2

    Molecular Mass: 274.788 g/mol

    Pharmacokinetics of Chlorpheniramine Maleate

    Chlorpheniramine maleate is absorbed comparatively slowly from the gastrointestinal tract, with peak plasma concentrations occurring approximately 2.5 to 6 hours after oral administration. It appears to undergo considerable first-pass metabolism. Besides, bioavailability is low and values of 25% to 50% having been noted. There is large inter-individual variation in the pharmacokinetics of chlorpheniramine; half-life values ranging between 2 and 43 hours noted.
