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.
