Pranav Roy answered
Opiate narcotic drugs are a type of analgesic drug. These drugs are derived from the opium poppy and are known for their ability to relieve pain by binding to opioid receptors in the brain and spinal cord.

Explanation:

• Opiate narcotic drugs are a type of medication that is used to treat pain. They are derived from the opium poppy and include drugs such as morphine, codeine, oxycodone, and hydrocodone.

• These drugs work by binding to specific receptors in the brain and spinal cord that are responsible for pain perception. When they bind to these receptors, they block the transmission of pain signals, which can provide significant pain relief.

• Opiate narcotics are often used to treat acute pain, such as pain following surgery or injury. They may also be used for chronic pain conditions, such as cancer pain or chronic back pain.

• However, opiate narcotics can also be highly addictive and can cause a range of side effects, including drowsiness, nausea, constipation, and respiratory depression. They can also be dangerous when taken in high doses or when combined with other drugs or alcohol.

• Because of their potential for addiction and abuse, opiate narcotics are tightly controlled by law enforcement and healthcare professionals. They are typically only prescribed for short-term use and under close medical supervision.

• In recent years, there has been growing concern about the overuse and abuse of opiate narcotics, particularly in the United States. This has led to increased efforts to educate healthcare professionals and patients about the risks of these drugs and to promote alternative pain management strategies.

Suresh Iyer answered
Sertumer, a pharmacist isolated the active principle of opium in 1806 and named it morphine. Morphine is a phenanthrene opioid receptor agonist, its main effect is binding to and activating the u-opioid receptors in the central nervous system. In clinical settings, morphine exerts its principal pharmacological effect on the central nervous system and gastrointestinal tract. Its primary actions of therapeutic value are analgesic and sedation.

Consumption of alcohol may lead to:
  • a)
    Accumulation of acetaldehyde in liver
  • b)
    Synthesis of fat in liver
  • c)
    Lowering of blood glucose level of the body
  • d)
    All of the above
Correct answer is option 'D'. Can you explain this answer?

Consumption of alcohol may lead to-
Accumulation of acetaldehyde in the liver: The metabolism of acetaldehyde produces excess NADH in liver mitochondria, which in turn leads to a decrease in beta-oxidation of long-chain fatty acids by inhibiting long-chain 3- hydroxy acyl- CoA dehydrogenase activity. Chronic alcohol consumption accelerates ADH- related alcohol metabolism to a limited extent.
Synthesis of fat in the liver: Hepatic fatty acid overload. Ethanol metabolism leads to excessive generation of reducing equivalents, thereby inhibiting fatty acid oxidation.
Lowering of the blood glucose level of the body: While moderate amounts of alcohol may cause blood sugar to rise, excess alcohol can actually decrease blood sugar level, sometimes causing it to drop into dangerous levels, especially people having type 1 diabetes. Beer and sweet wine contain carbohydrates and may rise blood sugar.
