Pain medicines

 Pain medicines, also known as analgesics, come in various forms and are used to relieve different types of pain such as headaches, muscle pain, joint pain, post-surgery pain, or chronic pain conditions. These medications are available in different dosage forms, including oral, topical, injectable, and more. Here’s a detailed explanation of pain medicines with their different dosage forms:

1. Non-Opioid Analgesics:

These are often the first line of treatment for mild to moderate pain. They are widely available and generally safe when used as directed.

a. Paracetamol (Acetaminophen):

• Indication: Mild to moderate pain such as headaches, toothaches, or minor body aches. It also helps reduce fever.

• Forms:

  • Tablets: 500 mg, 650 mg
  • Syrups: Commonly available for children, usually 120 mg/5 ml or 250 mg/5 ml.
  • Effervescent tablets: Dissolvable in water for quick relief (e.g., 500 mg).
