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.
