Slide 1

  • Topic: Chemistry in Everyday life - Analgesics, Morphine, its uses

Slide 2

  • Analgesics are compounds that help relieve pain without causing loss of consciousness.
  • Morphine is a natural analgesic extracted from the opium poppy.
  • It is used to treat moderate to severe pain.

Slide 3

  • Morphine is an alkaloid compound with the chemical formula C17H19NO3.
  • It is an opioid receptor agonist, meaning it binds to opioid receptors in the body.

Slide 4

  • The structure of morphine consists of a basic ring structure called a phenanthrene ring, which is fused to a piperidine ring.
  • Both rings contribute to the analgesic activity of morphine.

Slide 5

  • Morphine exerts its analgesic effects by binding to opioid receptors in the central nervous system.
  • This binding inhibits the transmission of pain signals along the neural pathways.

Slide 6

  • The analgesic properties of morphine also result in several side effects, such as sedation, respiratory depression, and constipation.

Slide 7

  • Due to its potential for addiction and abuse, morphine is classified as a Schedule II controlled substance.
  • It is primarily used in hospitals for pain management under strict supervision.

Slide 8

  • Morphine is often administered intravenously or via oral tablets.
  • It can also be found in combination with other drugs in certain analgesic formulations.

Slide 9

  • Morphine is not recommended for long-term use due to the risk of dependence and tolerance.
  • In cases where continuous pain relief is required, alternative analgesics may be prescribed.

Slide 10

  • Overall, morphine is an important analgesic agent used in medical settings to provide effective pain relief.
  • However, its use is strictly regulated due to its potential for abuse and side effects.

Slide 11

  • Topic: Chemistry in Everyday life - Anti-inflammatory Drugs, Aspirin, its uses

Slide 12

  • Anti-inflammatory drugs are medications used to reduce inflammation and relieve pain.
  • Aspirin, also known as acetylsalicylic acid, is one of the most commonly used anti-inflammatory drugs.

Slide 13

  • Aspirin belongs to a class of drugs called non-steroidal anti-inflammatory drugs (NSAIDs).
  • It works by inhibiting the production of prostaglandins, which are responsible for pain and inflammation.

Slide 14

  • The chemical structure of aspirin consists of an acetyl group (CH3CO) attached to a salicylic acid molecule.
  • This acetyl group allows aspirin to exert its anti-inflammatory effects.

Slide 15

  • Aspirin is used to treat a variety of conditions, such as headaches, fever, and inflammation.
  • It is also used as a blood-thinning medication to reduce the risk of blood clots.

Slide 16

  • The mechanism of action of aspirin involves the inhibition of cyclooxygenase (COX) enzymes.
  • COX enzymes play a key role in the synthesis of prostaglandins.

Slide 17

  • By inhibiting COX enzymes, aspirin prevents the formation of prostaglandins involved in pain and inflammation.
  • This leads to reduced pain, swelling, and fever.

Slide 18

  • Aspirin can have side effects, such as stomach irritation, increased bleeding, and allergic reactions.
  • It is important to carefully follow the recommended dosage and consult a healthcare professional if necessary.

Slide 19

  • Aspirin has several other uses beyond its anti-inflammatory properties.
  • It is used as a preventive measure for certain cardiovascular conditions, such as heart attacks and strokes.

Slide 20

  • Overall, aspirin is a versatile drug with both anti-inflammatory and blood-thinning properties.
  • However, it is important to use it responsibly and consult a healthcare professional for proper guidance.

Slide 21

  • Morphine is primarily used for the management of pain.
  • It is commonly used in cases of postoperative pain, cancer-related pain, and severe injuries.
  • The dosage and administration of morphine should be determined by a medical professional based on the patient’s condition and level of pain.

Slide 22

  • Morphine can cause various side effects, including drowsiness, dizziness, nausea, and vomiting.
  • It can also slow down breathing and heart rate, so it should be used with caution, especially in patients with respiratory or cardiovascular diseases.
  • Regular monitoring of vital signs is crucial during morphine administration.

Slide 23

  • Overdose or misuse of morphine can be life-threatening.
  • Naloxone is an opioid antagonist that can be administered to reverse the effects of morphine overdose and prevent respiratory depression.
  • Immediate medical attention is necessary in cases of suspected morphine overdose.

Slide 24

  • Morphine is metabolized in the liver by enzymes like cytochrome P450.
  • The liver metabolizes morphine into morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G), which are less potent but still have some analgesic effects.

Slide 25

  • The elimination half-life of morphine is around 2-4 hours.
  • It is primarily excreted through the kidneys in the form of metabolites.
  • Patients with impaired kidney function may require dosage adjustments to prevent accumulation of morphine and its metabolites.

Slide 26

  • Morphine can interact with other medications, such as sedatives, tranquilizers, and antidepressants, leading to increased sedation and respiratory depression.
  • It is essential for healthcare providers to review the patient’s medication history before prescribing morphine.

Slide 27

  • Morphine is a controlled substance due to its potential for abuse and addiction.
  • It is classified as a Schedule II drug in the United States.
  • Strict regulations are in place to prevent misuse and diversion of morphine.

Slide 28

  • Patients prescribed morphine should be educated about the correct use, potential side effects, and risks associated with the medication.
  • Proper storage and disposal of unused morphine should also be emphasized to prevent accidental ingestion by children or misuse by others.

Slide 29

  • In conclusion, morphine is a potent analgesic used to relieve severe pain.
  • Its use should be closely monitored, and patients should be informed about the potential side effects and risks.
  • Healthcare professionals play a crucial role in ensuring the safe and responsible use of morphine.
