    Study Notes

    Reserpine

    • May cause severe depression that can lead to suicide, which is why it's no longer commonly used as an antihypertensive.
    • Side effects include orthostatic hypotension, weakness, fatigue, and insomnia.

    Contraindications

    • No specific contraindications mentioned, but its use is limited due to its side effects.

    Uses of Reserpine

    • Mainly used to treat myasthenia gravis.
    • Administered orally in a dose of 60mg, 4 times a day, or in a sustained-release tablet format, which has a longer duration and fewer side effects.

    Drug Incompatibility

    • Pharmaceutical preparations may involve incompatibility between constituents, affecting the preparation's stability and potency.
    • Important to consider these interactions when preparing medications.

    Characteristics of a Mechanism

    • Requires a carrier.
    • Requires energy.
    • Works against concentration gradient.
    • Is selective.
    • Transports compounds with high molecular weight.

    Pharmacokinetics

    • Figure 3:6 shows a concentration-time profile of different routes of administration of the same drug and dose.
    • Important factors to consider in pharmacokinetics include:
      • Distribution of the drug in the body.
      • Rate of elimination of the drug.
