			==Pharmacokinetics==
			*Onset of drug action:
			**IV: 1 to 3 minutes
			**IM: 15 to 30 minutes
			**Oral: 30 to 60 minutes
			*Duration: 1-6 hours, depending on the route and dose.
			*Half-Life: 1.5 to 2.5 hours in adults; longer in elderly and children.
			*Metabolism: Hepatic via CYP3A4 to active metabolites.
			*Excretion: Primarily renal.

			==Drug Precautions==
			'''Pregnancy

			Use only if benefits outweigh risks; potential risk to the fetus.

			'''Breastfeeding

			Excreted in breast milk; not recommended.

			'''Children and Elderly

			Use with caution; Elderly may require lower doses due to increased sensitivity.

			'''Monitoring Requirements

			Respiratory rate, blood pressure, sedation level, signs of respiratory depression.

			'''Drug Interactions
			*Inhibitors of CYP3A4 enzyme like macrolide antibiotics, azole antifungals, protease inhibitors, calcium channel blockers.
			**Can prolong sedation.
			*Avoid Opioids, barbiturates, alcohol, and other benzodiazepines.
			**Increased risk of respiratory depression.
			*Herbal products like St. John's wort.
			**Can affect metabolism of midazolam.

			==FAQ==
			'''How Should I Take the Tablet?

			Take exactly as prescribed, usually 1 to 2 times daily with or without food.

			'''What Should I Avoid While Taking?

			Avoid alcohol and other CNS depressants, and be cautious when driving or operating machinery until you know how midazolam affects you.

			'''What Happens if I Miss a Dose?

			==Common Strengths of Midazolam==
			Midazolam are available in the following strengths:
			*Injectable Solution:
			**1 mg/mL
			**2 mg/mL
			**5 mg/mL
			*Oral Solution:
			**10 mg/5 mL
			*Tablet:
			**15 mg

			==Drug Trade Names of Midazolam==
			Dormicum

			==Drug Usage==
			Midazolam is used for:
			*Procedural sedation
			*Induction of anesthesia
			*Sedation in intensive care settings
			*Treatment of status epilepticus
			*Preoperative sedation

			==Mechanism of Action==
			Midazolam enhances the effect of GABA (gamma-aminobutyric acid), the primary inhibitory neurotransmitter in the brain, by binding to GABA<sub>A</sub> receptors. This results in sedative, anxiolytic, muscle relaxant, and anticonvulsant effects.

			==Route of Administration==
			Midazolam can be administered via:
			*Oral (tablets, solution)
			*Intravenous (IV)
			*Intramuscular (IM)
			*Intranasal

			==Dosages==
			*Sedation:
			**IV: 1 to 2.5 mg, may repeat every 2-3 minutes as needed (max 5 mg).
			**IM: 0.07 to 0.08 mg/kg, max 10 mg.
			*Induction of Anesthesia:
			**IV: 0.1 to 0.2 mg/kg, may repeat as needed.
			*Elderly or Debilitated Patients:
			**Start with lower doses (e.g. 0.5 mg to 1 mg) and titrate carefully.
