Understanding Drug Treatment
The drug treatment process can be viewed from two perspectives: micro and macro. The micro perspective focuses on the patient-practitioner interaction, while the macro perspective considers the healthcare system's role in ensuring rational drug use.
Rational Use of Drugs
Rational drug use is defined as the safe, effective, appropriate, and economical use of medications. Pharmacists play a vital role in promoting rational use by understanding the following aspects:
1- Safety: This involves assessing the relative and absolute safety of medications, considering factors like disease severity, treatment options, and potential side effects.
2- Effectiveness: Effectiveness refers to how well a drug works in real-world settings, considering patient populations and potential confounding factors. Efficacy, on the other hand, refers to a drug's performance in controlled clinical trials.
3- Appropriateness: This dimension ensures the correct medication is prescribed for the right indication, with no contraindications, proper dosage, and administration instructions. Additionally, proper dispensing with sufficient information and counseling is crucial.
4- Cost-Effectiveness: While cost is a factor, a cost-effectiveness approach is preferred. This considers the overall impact on patient outcomes, including potential cost savings from avoiding future complications.
Functions of Drugs
Beyond their therapeutic effects, medications can serve various social and behavioral functions for both individuals and society. Pharmacists should consider these functions when interacting with patients:
· Therapeutic Function: The primary function of medications is to prevent, treat, and cure diseases.
· Placebo Function: Placebos can provide a psychological benefit and show concern for the patient.
· Coping Function: Medications can help manage feelings of stress, grief, or loneliness.
· Self-Regulatory Function: Medications can empower patients to manage chronic conditions.
· Social Control Function: In some cases, medications are used to manage disruptive behavior.
· Recreational Function: Certain medications are misused for pleasure or relaxation.
· Other Functions: Medications can also serve cosmetic, appetite-suppressant, or performance-enhancing purposes.
Prescribing Decisions
The process of prescribing medication has gained significant attention due to rising drug costs and concerns about rational prescribing. Pharmacists can influence prescribing habits by understanding the factors that influence physicians' decisions:
1- Physician Characteristics: Age, experience, and attitudes towards drug use can influence prescribing patterns.
2- Social Environment: Factors like social norms and exposure to drug marketing can impact prescribing choices.
3- Patient Factors: Age, gender, and consultation rates can influence the medications a patient receives.
4- Physician-Patient Interaction: The dynamics of the interaction can influence the medications prescribed.
5- Non-Pharmacological Alternatives: The availability of non-drug therapies can influence prescribing decisions.
Choosing the Right Drug
When selecting a medication, several factors are considered:
1- Therapeutic Effect: The primary goal is to choose a medication with the best chance of achieving the desired outcome.
2- Side Effects: Minimizing the risk and severity of side effects is crucial.
3- Cost: While cost is a factor, it is often secondary to therapeutic effect and safety considerations.
4- Patient Preferences: Whenever possible, patient preferences regarding factors like convenience and taste should be considered.
Influencing Prescribing Behavior
Pharmacists play a key role in promoting rational drug use through various methods:
· Drug Information and Education: Pharmacists can provide physicians with up-to-date information on medications to guide prescribing decisions.
· Individual Feedback: Personalized feedback and one-on-one education can be more effective than printed materials.
· Managerial and Regulatory Activities: Pharmacists can be involved in implementing strategies like limited drug lists and formularies to promote rational prescribing.
By understanding the drug treatment process and the factors influencing prescribing behavior, pharmacists can significantly contribute to ensuring the safe, effective, and appropriate use of medications.
