Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

1.2K
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Drug Abuse and Addiction: Pharmacological Phenomena

1.4K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Drug Accumulation During Multiple Dosing: Repetitive IV Injections

343
Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...

Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

1.9K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices

57
Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.3K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Area of Science:

  • Addiction Medicine
  • Pharmacology
  • Public Health

Background:

  • Recent randomized control trials (RCTs) indicate supervised injectable heroin (SIH) efficacy for persistent street heroin users in methadone treatment.
  • Short-term RCTs have limitations in evaluating chronic, relapsing addiction disorders and capturing SIH treatment dynamics over time.

Purpose of the Study:

  • To review the effectiveness of supervised injectable heroin (SIH) in treating individuals with chronic heroin addiction.
  • To explore the long-term impact and mechanisms of action of SIH in a clinical setting.

Main Methods:

  • This study is a narrative review based on published data analysis.
  • Reflective analysis incorporates clinical experience with SIH delivery and its variations.

Main Results:

  • SIH is sufficiently reinforcing to engage many long-term, marginalized heroin users in daily, structured treatment.
  • Adequate methadone dosage combined with occasional SIH can maintain treatment adherence.
  • Participation in SIH treatment correlates with reduced non-prescribed drug use, improved self-perception, and for some, social reintegration and eventual treatment withdrawal.

Conclusions:

  • Supervised injectable heroin (SIH) effectively motivates a proportion of recidivist addicts towards long-term treatment engagement.
  • Structured treatment offers a reprieve from compulsive drug use, facilitating gradual positive changes.
  • Successful withdrawal from SIH, when achieved, is a slow and non-linear process.
