What this trial studies

Adults aged 21–50 with clinically diagnosed post-dural puncture headache and a pain score of at least 5 are enrolled at Tanta University and given one of three medications (theophylline, sumatriptan, or gabapentin). The study compares how well each drug reduces headache severity and records side effects to compare safety. Treatments are given per protocol and patients are followed for clinical response and adverse events. Outcomes focus on pain relief magnitude and tolerability.

Who should consider this trial

Good fit: Adults 21–50 years old with PDPH meeting International Headache Society criteria, ASA physical status I–II, and a numeric pain rating of ≥5 are the intended participants.

Not a fit: People who are pregnant, have chronic headache disorders, significant cardiovascular disease, thyroid/liver/kidney impairment, or contraindications to the study drugs are unlikely to benefit from these treatments.

Why it matters

Potential benefit: If successful, the trial could identify an effective, low-cost medication option to relieve PDPH without needing invasive procedures.

How similar studies have performed: Smaller previous reports have suggested benefit from theophylline and sumatriptan for PDPH, but direct head-to-head comparative data are limited.
