Prospective Process Validation of Paracetamol Tablets

Paracetamol 

Paracetamol/acetaminophen is the most commonly used analgesic and antipyretic drug, It is the drug of choice in patients who cannot be treated with non-steroidal anti-inflammatory drugs (NSAID), such as people with bronchial asthma, peptic ulcer disease, hemophilia, salicylate-sensitized people, children under 12 years of age, pregnant or breastfeeding women. It is recommended as a first-line treatment of pain associated with osteoarthritis. The mechanism of action is complex and includes the effects of both the peripheral (COX inhibition), and central (COX, serotonergic descending neuronal pathway, L-arginine/NO pathway, cannabinoid system) antinociception processes and “redox” mechanism. Paracetamol is a well-tolerated drug and produces few side effects from the gastrointestinal tract, however, despite that, every year, has seen a steadily increasing number of registered cases of paracetamol-induced liver intoxication all over the world.

Paracetamol is used for pain relief and fever. It is used to relieve pain in conditions like headache, muscle pain, or dental pain.
How Paracetamol works
Paracetamol is an analgesic (pain reliever) and antipyretic (fever reducer). It works by blocking the release of certain chemical messengers that cause pain and fever.

Common side effects of Paracetamol

Nausea, Vomiting, Insomnia (difficulty in sleeping), Headache, Constipation, Itching

RATIONALE FOR SELECTION OF CRITICAL STEPS AND ITS PROCESS PARAMETERS  FOR VALIDATION :

A) Blending: This step involves mixing of granules with other Excipients and lubricants. The purpose of blending is to get a uniform distribution of Paracetamol to get good flow and anti-adhesion properties of the blend. Mixing speed and time are critical variables in this process. Since the speed of the blender is constant, the time required for proper mixing shall be determined. Mixing time is critical as less blending will result in a non-uniform distribution of drugs and poor flow whereas more blending will result in de-mixing leading to a non-uniform distribution of drugs and an increase in disintegration time.

In addition to this Following tests shall be carried out for information purposes. This shall be carried out on final time interval samples only.

  1. Loss on drying
  2. Bulk Density
  3. Sieve analysis
  4. Compressibility Index

B) Compression: This step involves the conversion of blended material into tablets as per specifications. The speed of the machine is a major variable. The following physical parameters are to be checked to establish the above-mentioned variables at regular intervals

  • Appearance
  • Average Mass
  • A mass of 20 Tablets
  • Resistance to Crushing
  • Thickness
  • Friability
  • Disintegration time
  • Length and Width

SAMPLING PROCEDURE & LOCATION DIAGRAM

At Compression Stage – Sampling Locations for Hopper Level

Procedure: Compression setting shall be done as per batch manufacturing record. During sampling ensure the hopper level as per the below-mentioned diagram. Initial sampling shall be performed for full Hopper and after that Half Hopper and then quarter Hopper.  Sampling shall be performed directly from the chute of the compression machine.
