Miconazole

Miconazole is an  imidazole antifungal agent commonly used in topical sprays, creams and ointments applied to the  skin to cure fungal infections such as Athlete's foot and Jock itch. It may also be used internally to treat vaginal  yeast infection.

When used by a person taking the anticoagulant medication warfarin, Miconazole may cause an adverse reaction which can lead to excessive bleeding or bruising.

Propoxyphene

• A methadone analog.Used orally to relieve mild to moderate pain.
• A typical opiate, it does not possess anti-inflammatory or antipyretic actions, but has little or no antitussive activity.
• Cannot be used parenterally because of irritant properties.
• Has a low addiction potential primarily due to its lack of potency as an opiate.
• The most common adverse side effects are:• dizziness, drowsiness, and nausea and vomiting. • these effects are more prominent in ambulatory patients.
• Withdrawal symptoms have occurred in both adults and in neonates following use of the drug by the mother during pregnancy.
• CNS depression is additive with other CNS depressants.

Procaine penicillin Procaine penicillin is a combination of benzylpenicillin with the local anaesthetic agent procaine. This combination is aimed at reducing the pain and discomfort associated with a large intramuscular injection of penicillin.

Benzodiazepines
All metabolites are active sedatives except the final glucuronide product. Elimination half-life varies a great deal from drug to drug.

?-Hydroxylation is a rapid route of metabolism that is unique to triazolam, midazolam, and alprazolam.
This accounts for the very rapid metabolism and short sedative actions of these drugs.

Pharmacological effects of benzodiazepines

- Antianxiety.
- Sedation.
- Anticonvulsant (including drug-induced convulsions).
- Amnesia, especially drugs like triazolam.
- Relax skeletal muscle (act on CNS polysynaptic pathways).

Indications

- IV sedation, (e.g., midazolam, diazepam, lorazepam).
- Antianxiety.
- Sleep induction.
- Anticonvulsant (e.g., diazepam, clonazepam).
- Panic disorders.
- Muscle relaxation.


Adverse effects

- Ataxia, confusion.
- Excessive sedation.
- Amnesia (not a desired effect with daytime sedation).
- Altered sleep patterns (increase stage 2 and decrease stage 4 sleep).
