Study Notes

Opioids and Side Effects

Low doses of opioids can cause side effects, particularly constipation.
These side effects might complicate overdose treatment without offering significant pain relief.

2-Imipenem

2-Imipenem is partially inactivated in the kidney due to enzymatic activity.
Administered with cilastatin, an enzyme inhibitor, to block renal metabolism and enhance effectiveness.

Doxycycline Usage

Common indications for doxycycline include:
- Genital Chlamydia infections.
- Acne treatment.
- Brucellosis, typically in combination with rifampicin.

Tricyclic Antidepressants (TCAs)

TCAs exhibit several pharmacological effects:
- α-adrenergic blockade leading to orthostatic hypotension.
- Antihistaminic effects causing sedation.
- Anticholinergic effects resulting in related symptoms.
TCAs can also present cardiotoxic effects, necessitating careful monitoring.

Drug Formulations
