Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

1.3K
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...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

281
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Hepatic Portal System01:21

Hepatic Portal System

6.1K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Continuing Care01:25

Continuing Care

2.0K
Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

    Area of Science:

    • Hepatology
    • Addiction Medicine
    • Telehealth

    Background:

    • Individuals with opioid use disorder (OUD) are a priority for hepatitis C (HCV) diagnosis and treatment.
    • Integrating HCV treatment into OUD care via telemedicine presents a novel approach to improve patient outcomes.

    Purpose of the Study:

    • To evaluate the feasibility and outcomes of HCV treatment within a telemedicine-based OUD program.
    • To identify barriers to HCV treatment access in this patient population.

    Main Methods:

    • A retrospective chart review was conducted on patients receiving HCV treatment through a telemedicine OUD program.
    • Data collected included demographics, HCV history, prior authorization status, treatment initiation and completion, and viral clearance.

    Main Results:

    • Sixty-three treatment-naïve patients with OUD were prescribed antiviral therapy for HCV.
    • The median patient age was 36, 41% were female, and 57% had Medicaid insurance.
    • Despite 52% treatment completion, approximately 20% of patients faced prior authorization denials for antiviral therapy.

    Conclusions:

    • Telehealth platforms are a viable option for delivering HCV treatment to patients with OUD.
    • Policy changes to ease payer restrictions on antiviral coverage are crucial for enhancing medication accessibility through telehealth.
